A Theological Dictionary

Terms, concepts and people, in plain words first

I have views on plenty of this. Here, the job is to set out the positions fairly, not argue mine.

Terms [29]

Vocabulary. Mostly Greek and Latin words you meet in reading and need decoded before the sentence makes sense.

Allegory Greek

Reading a text for a meaning underneath the surface one.

On the timeline: Origen writes On First Principles and Against Celsus, c. 230 to 250

More about Allegory

Associated with Alexandria and above all with Origen, who read scripture on a literal, a moral and a spiritual level. Antioch preferred to stay nearer the plain sense. Modern readers are usually taught to distrust allegory, though the line between it and typology is thinner than the textbooks let on.

Origen of Alexandria · Quadriga · Typology

Apocrypha Greek

Books in the Greek Old Testament that are not in the Hebrew Bible.

More about Apocrypha

Catholic churches receive them as scripture and call them deuterocanonical. The Orthodox churches receive them too, on a slightly longer list and usually under a different name. Protestant churches do not, though the Reformers valued them for reading and early Protestant Bibles printed them. Jerome raised the question when he translated from the Hebrew, and Augustine disagreed with him about it.

Canon · Jerome · Septuagint

Apologist Greek

A defender. Someone who argues the case for Christianity to people outside it.

On the timeline: Justin Martyr writes the First Apology, c. 155

More about Apologist

From apologia, a speech for the defence in court, which is how 1 Peter 3:15 uses it. The second century apologists, Justin above all, were writing to the emperor and to the educated public. Nothing in the word has anything to do with apologising.

Justin Martyr · Logos

Canon Greek

A measuring rod. The list of books the church receives as scripture.

On the timeline: Athanasius lists the twenty seven books of the New Testament, 367 · The four gospels reach their written form, c. 65 to 100 · Marcion is expelled from the church at Rome, c. 144

More about Canon

The canon was recognised rather than decreed. Books already being read everywhere, and traceable back to the apostolic circle, settled into place over roughly three centuries. Athanasius in 367 gives the first surviving list that matches the present New Testament exactly.

Apocrypha · Marcionism · Septuagint

Catechesis Greek

Teaching someone the faith, usually before they are baptised.

More about Catechesis

The early church took it very seriously. The catechumenate could run for years, and it ended with a formal handing over of the creed. The Reformation catechisms, Luther's, Heidelberg and Westminster, are the same instinct put into print.

Confession · Creed

Christology Greek

The doctrine of the person of Christ. Who he is, rather than what he did.

More about Christology

The classic split is between the person of Christ, which is christology proper, and the work of Christ, which is soteriology. The first five centuries are mostly taken up with the first question, and the great councils are the milestones along the way.

The Chalcedonian Definition · The hypostatic union · Soteriology

Creed Latin

From credo, I believe. A short agreed statement of faith.

More about Creed

Creeds grew out of the questions put to people at baptism, and out of the rule of faith. The Apostles' Creed is western and later than its name suggests. The Nicene Creed comes from councils. The Athanasian Creed is neither by Athanasius nor from a council.

Confession · The rule of faith

Ecclesiology Greek

The doctrine of the church. What it is, who belongs, and who leads.

More about Ecclesiology

Most church splits are ecclesiological before they are anything else. The questions keep coming back in the same shape Cyprian and the Donatists met them in. Is the church defined by holiness or by grace? And does the failure of a minister invalidate what he does?

The marks of the church · Donatism · Ekklesia · Episcopacy

Eisegesis Greek

Reading your own meaning into a text. The thing exegesis is supposed to prevent.

More about Eisegesis

Nobody sets out to do it. It is what happens when the conclusion is settled before the reading starts, and it is most dangerous when the conclusion is one you are fond of.

Exegesis · Hermeneutics

Ekklesia Greek · ek-klay-SEE-a

Assembly. The New Testament word we translate as church.

On the timeline: Pentecost, c. 30 or 33

More about Ekklesia

In ordinary Greek it meant a civic gathering, citizens called out to decide something. The Septuagint uses it for the assembly of Israel, and that is the more important background. It never means a building.

The marks of the church · Ecclesiology

Eschatology Greek

The doctrine of last things. Death, judgement, resurrection, new creation.

More about Eschatology

Modern theology has increasingly argued that this is not an appendix at the end of the syllabus but a dimension running through the whole of it. The New Testament treats the last days as already begun in the resurrection and not yet finished, which usually gets called inaugurated eschatology.

The kingdom of God · Parousia · Resurrection

Exegesis Greek

Drawing the meaning out of a text.

More about Exegesis

Reading a passage in its own language, its own genre and its own setting, and letting it say what it says. It is slow work and there is no shortcut.

Eisegesis · Hermeneutics

Hermeneutics Greek

The theory of interpretation. The rules you are using, whether you know it or not.

More about Hermeneutics

Exegesis is the act of interpreting a passage. Hermeneutics is the account of how interpretation works at all. Everyone has one. The only question is whether it has ever been looked at.

Allegory · Exegesis · The rule of faith · Typology

Homoiousios Greek · ho-moy-OO-see-os

Of similar being. One Greek letter away from homoousios, and the difference mattered.

More about Homoiousios

The compromise party wanted to say the Son is like the Father in being. Gibbon sneered that the world was convulsed over a single letter. But the argument was about whether the Son is God or the highest of creatures, which is not a small distinction however small the spelling. Many who used the word were not Arians, and Athanasius himself treated them as brothers who meant the right thing badly.

Arianism · Homoousios

Homoousios Greek · ho-mo-OO-see-os

Of the same being. The word Nicaea used to say the Son is God in the same sense the Father is.

On the timeline: The Arian controversy breaks out in Alexandria, c. 318 to 321 · The Council of Nicaea, 325

More about Homoousios

Nicaea picked a word that does not appear in the Bible, which was controversial then and still gets raised as an objection. The council's answer was that the Arians could agree to every biblical phrase while meaning something else by it, so a word was needed that they could not sign. It rules out the idea that the Son is merely very like God.

Arianism · Homoiousios · Ousia

Hypostasis Greek · hy-POS-ta-sis

A particular concrete existence. In trinitarian language, a person.

On the timeline: The Cappadocian Fathers, c. 360 to 395

More about Hypostasis

It originally meant much the same as ousia, which is why the fourth century was so confused. The Cappadocians fixed the distinction. One ousia, three hypostases. In christology the word does different work again, because Chalcedon says the two natures meet in one hypostasis.

The hypostatic union · Ousia · Persona · The Trinity

Kerygma Greek · ke-RIG-ma

The proclamation. The core announcement the church made about Jesus.

On the timeline: The crucifixion and resurrection of Jesus, c. 30 or 33

More about Kerygma

Set against didache, which is teaching. The kerygma is the news itself. Christ died, was buried, was raised, appeared. Scholars have tried to reconstruct its earliest shape from formulas buried in the New Testament, especially in 1 Corinthians 15.

Gospel · Resurrection

Logos Greek · LOH-goss

Word, reason, principle. The title John gives Christ in his first chapter.

On the timeline: Justin Martyr writes the First Apology, c. 155

More about Logos

The term already carried weight in Greek philosophy, where it named the rational order of the universe. John takes it and says that ordering principle became flesh. Justin and the apologists used the overlap to argue that whatever is true in philosophy already belongs to Christ.

Apologist · The Incarnation · Justin Martyr

Ousia Greek · OO-see-a

Being, or substance. What a thing is.

On the timeline: The Cappadocian Fathers, c. 360 to 395

More about Ousia

In trinitarian language, God is one ousia. Latin renders it substantia, which is why the western creeds talk about one substance. Part of the confusion in the fourth century was simply linguistic. Greek and Latin speakers were using cognate words for different things.

Homoousios · Hypostasis · The Trinity

Parousia Greek · pa-roo-SEE-a

Presence, or arrival. The New Testament word for the return of Christ.

More about Parousia

In ordinary Greek it described the state visit of a king or a governor to a city, which fits the New Testament use better than the English word coming does. The city goes out to meet the ruler on the road and walks him in.

Eschatology

Patristics Latin

The study of the church fathers, roughly from the end of the New Testament to the eighth century.

More about Patristics

The boundaries are a convention rather than anything natural. In the west the period is usually closed with Gregory the Great in 604, in the east with John of Damascus in the eighth century. Patrology strictly means the study of the writers and patristics the study of their thought, though in practice the words get used loosely.

Apologist · The Apostolic Fathers

Perichoresis Greek · peri-kho-RAY-sis

The three persons of the Trinity living in one another.

More about Perichoresis

Each person wholly contains and is contained by the others, and none of them loses what makes them distinct. The Latin equivalent is circumincession. It is the answer to the question of how three persons are one God without being three parts of God.

Hypostasis · The Trinity

Persona Latin

Person. The Latin word behind the three persons of the Trinity.

On the timeline: Tertullian writes in Latin, c. 197 to 210

More about Persona

Tertullian brought it in. It originally meant a mask, or a role, which has caused centuries of anxiety that it might suggest God playing three parts. It does not mean person in the modern sense of a separate centre of consciousness. Read it that way and you end up with three gods.

Hypostasis · Modalism · Tertullian · The Trinity

Pneumatology Greek

The doctrine of the Holy Spirit.

On the timeline: Azusa Street, 1906 · The Cappadocian Fathers, c. 360 to 395 · The First Council of Constantinople, 381 · Pentecost, c. 30 or 33

More about Pneumatology

Nicaea in 325 said very little about the Spirit. Basil's On the Holy Spirit and the Council of Constantinople in 381 supplied what was missing. That pneumatology stays thin next to christology is a complaint modern theology keeps making.

Basil of Caesarea · Filioque · Pentecostalism · The Trinity

Quadriga Latin

The medieval fourfold sense of scripture. Literal, allegorical, moral and anagogical.

More about Quadriga

A four horse chariot, hence the name. The literal sense tells you what happened, the allegorical what to believe, the moral what to do, the anagogical what to hope for. Jerusalem is the worked example everyone uses. A city, the church, the faithful soul, and the heavenly city.

Allegory · Hermeneutics

Septuagint Latin

The ancient Greek translation of the Old Testament, written LXX.

More about Septuagint

Made for Greek speaking Jews from the third century BC onwards. It is the version most New Testament writers quote, which is why their Old Testament citations sometimes do not match the Hebrew wording. It also carries a wider book list than the Hebrew Bible.

Apocrypha · Canon

Soteriology Greek

The doctrine of salvation. What God has done about the human problem, and how.

On the timeline: Athanasius becomes bishop of Alexandria, 328

More about Soteriology

It is tied at every point to christology. What you think Christ had to be depends on what you think had to be fixed. That is exactly the move Athanasius makes against Arius, and it is why the two doctrines cannot be studied apart.

Atonement · Christology · Deification · Justification

Theotokos Greek · thay-o-TOH-kos

God-bearer. The title of Mary confirmed at Ephesus in 431.

On the timeline: The Council of Ephesus, 431

More about Theotokos

The word says something about Christ before it says anything about Mary. If the one she bore is God the Son, then she bore God. Nestorius preferred Christotokos, and the council judged that this split Christ into two subjects.

Cyril of Alexandria · The hypostatic union · Nestorianism · Nestorius

Typology Greek

Reading earlier people, events and institutions as patterns that point forward to Christ.

More about Typology

Different from allegory in that typology holds the historical events really happened and really do point forward, rather than standing in for something else. Adam and Christ. The exodus and redemption. The temple and the incarnation. The New Testament does it constantly, which is the main argument for its legitimacy.

Allegory · Biblical theology · Temple and sacred geography

Concepts [89]

The ideas themselves. Doctrines, methods, practices, controversies and movements.

Analogy Method

Language about God is neither literal nor meaningless. It is analogical.

On the timeline: Thomas Aquinas writes the Summa Theologiae, 1265 to 1274

More about Analogy

When we call God good, the word is not being used exactly as it is of a person, or the creator would be a creature. Nor is it being used with no connection at all, or we would be saying nothing. Aquinas' doctrine of analogy is the classic attempt to hold the middle ground.

Thomas Aquinas · Natural theology

The Apostolic Fathers Movement

The generation of Christian writers straight after the apostles.

On the timeline: 1 Clement, c. 96 · The Didache, c. 50 to 120

More about The Apostolic Fathers

A modern collective name, not one they used. Clement of Rome, Ignatius, Polycarp, the Didache, Barnabas and the Shepherd of Hermas. They are not systematic theologians. They are pastors writing to churches under pressure, and that is what makes them worth reading.

Clement of Rome · Ignatius of Antioch · Patristics · Polycarp of Smyrna

Arianism Controversy

The Son is the highest of creatures, not God in the full sense.

On the timeline: The Arian controversy breaks out in Alexandria, c. 318 to 321

More about Arianism

Arius was defending the uniqueness of God, not attacking Christ. But if the Son is created then he shares in God rather than possessing divinity, and he cannot give what he does not have. Athanasius' answer is about salvation. A creature cannot save creatures.

Arius · Athanasius of Alexandria · Homoousios · 325 · Participation

Arminianism Controversy

Election rests on foreseen faith, and grace can be resisted.

On the timeline: The Synod of Dort, 1618 to 1619

More about Arminianism

Named for Jacobus Arminius, a Reformed minister trained in Geneva. His followers, the Remonstrants, put five points to the Dutch church in 1610 and the Synod of Dort answered each one. They are not semi-Pelagians. The Remonstrance affirms that a person can do nothing good without grace going before, and the argument is about whether that grace can be refused. Wesley later took up a version of it, which is why the Methodist and Reformed traditions still divide here.

Free will · Predestination · John Wesley

Atonement Doctrine

What the death and resurrection of Christ actually accomplish.

On the timeline: Anselm writes Cur Deus Homo, 1098

More about Atonement

The church has never dogmatised a single theory, which is unusual. Ransom, victory over the powers, satisfaction, penal substitution, moral example, recapitulation. All have been held, often together. The New Testament uses several images at once, and whether one of them is the controlling image is itself part of the argument.

Christus Victor · Penal substitution · Recapitulation · Satisfaction · Soteriology

Biblical theology Method

Reading the Bible as one unfolding story, on its own terms and in its own order.

More about Biblical theology

Different from systematic theology, which arranges everything by topic. Biblical theology asks what a book, or a stage of the story, contributes where it stands, and then traces the themes forward. Creation, exile, temple, kingship, covenant. It is the dominant method in a lot of current evangelical scholarship.

Covenant · Systematic theology · Temple and sacred geography · Typology

The Chalcedonian Definition Doctrine

The 451 statement that Christ is one person in two natures, fully God and fully human.

On the timeline: The Council of Chalcedon, 451

More about The Chalcedonian Definition

It is the standard of christological orthodoxy for Catholic, Orthodox and most Protestant churches. It works largely by exclusion, ruling out the answers that had already failed, and it deliberately does not explain the mechanism. Not all churches received it, and the Oriental Orthodox split dates from here.

The hypostatic union · Monophysitism

Christus Victor Doctrine

The cross as a victory over sin, death and the devil.

More about Christus Victor

Prominent in the early church and in the east. Gustaf Aulen's 1931 book gave it the name and argued it had been wrongly displaced in the west, a historical claim that has been much disputed since. It reads the cross and the resurrection together as a single act of liberation. Many who hold it hold a substitutionary account as well, and do not treat the two as alternatives.

Atonement · Recapitulation

The Confessing Church Movement

The German Protestants who refused to let the Nazi state define the church.

More about The Confessing Church

Formed in 1934 around the Barmen Declaration, against the German Christians who wanted the church lined up with the regime. Its record is mixed. Plenty of members opposed state control of the church without opposing much else, and only a minority went as far as Bonhoeffer.

1934 · Karl Barth · Dietrich Bonhoeffer · Confession

Constantinianism Controversy

A critical name for the church's alliance with state power after Constantine.

On the timeline: Constantine at the Milvian Bridge, 312

More about Constantinianism

The term is polemical, and it comes from John Howard Yoder and the Anabaptist tradition. Yoder's own denomination later documented his record of sustained sexual abuse and harassment of dozens of women over several decades, confirmed by a 2015 peer reviewed historical study. The word names the moment the church stopped being a persecuted minority and started having access to force. Whether 313 was a rescue or a fall is one of the oldest arguments in church history.

Constantine · 313 · The two cities

Conversion Practice

Turning. A change of allegiance, and in evangelical usage often a datable one.

On the timeline: The Evangelical Revival and the Great Awakening, c. 1730 to 1760

More about Conversion

The tradition holds two things together. Sudden turnings, like Paul's and Augustine's, and the slow forming of people raised in the faith. Insisting that everyone must have the first kind has caused a great deal of unnecessary anxiety.

386 · Evangelicalism

Council Practice

A gathering of bishops to settle a disputed question for the whole church.

On the timeline: The Council of Jerusalem, c. 49 · The Council of Nicaea, 325

More about Council

The pattern goes back to Acts 15. Seven councils, from Nicaea in 325 to the Second Nicaea in 787, are received as ecumenical by both east and west. The Roman Catholic Church counts twenty one. Which councils count is itself part of the disagreement.

451

Covenant Doctrine

A binding relationship, sworn, with obligations, between God and a people.

More about Covenant

The organising idea of much of the Old Testament, and the frame the New Testament reads it within. Noah, Abraham, Moses, David, and the new covenant in Christ. Whether these are stages of one covenant or genuinely separate arrangements is the fault line between covenant theology and dispensationalism.

Biblical theology · Law and gospel · Supersessionism

Deification Doctrine

Also called theosis. Sharing in the life of God without ever becoming God.

On the timeline: Athanasius becomes bishop of Alexandria, 328 · Athanasius writes On the Incarnation, c. 318 to 335

More about Deification

Athanasius' famous line is that he became human so that we might become divine. The claim is participation, not absorption. Humanity is taken into the relationship the Son has with the Father, by grace, and the line between creator and creature holds absolutely. It is central to Orthodox theology and it has been recovered in the west over recent decades.

Athanasius of Alexandria · Participation · Recapitulation · Soteriology

The divine dilemma Doctrine

Athanasius' framing. God's justice requires death for sin, God's goodness will not abandon his image.

On the timeline: Athanasius writes On the Incarnation, c. 318 to 335

More about The divine dilemma

Repentance on its own cannot solve it, because repentance does not undo corruption. Only the Word, taking a body that can die, can satisfy the sentence and remake the nature at the same time. It is the engine of the argument in On the Incarnation.

Athanasius of Alexandria · Atonement · Deification

The documentary hypothesis Controversy

The theory that the Pentateuch was put together from four earlier sources.

On the timeline: The rise of historical criticism, c. 1780 to 1900

More about The documentary hypothesis

The classical form, associated with Wellhausen, identifies J, E, D and P. The consensus behind it has weakened a great deal and few scholars now hold the original version. The underlying question, of how the Pentateuch came together, is still a real one.

Biblical theology · Higher criticism

Dogma Method

A teaching the church has formally defined as binding.

More about Dogma

Narrower than doctrine, which covers Christian teaching in general. The Trinity and the two natures of Christ are dogma. A great deal else is doctrine, held with varying degrees of confidence, and being able to tell the difference is part of growing up theologically.

Council · Creed · Systematic theology

Donatism Controversy

Sacraments performed by unworthy ministers are invalid.

On the timeline: The Great Persecution, 303 to 311

More about Donatism

The African church split over clergy who had handed scriptures to the authorities during the Great Persecution. Augustine's answer was that the sacraments belong to Christ and not to the minister, so their validity does not rest on the minister's holiness. The controversy also moved Augustine, who had opposed coercion, to defend the use of state force against the Donatists. He argued it from the parable's compel them to come in, and it was quoted for centuries afterwards to justify a great deal.

Augustine of Hippo · Ecclesiology · Novatianism

Ecumenism Movement

The effort to heal the divisions between the churches.

On the timeline: The Second Vatican Council, 1962 to 1965

More about Ecumenism

From the Greek for the whole inhabited world. Modern ecumenism grew out of the missionary movement, which found competing denominations impossible to defend on the field. The World Council of Churches and the Second Vatican Council are its landmarks.

World Christianity

Episcopacy Practice

Government of the church by bishops.

On the timeline: 1 Clement, c. 96 · Cyprian of Carthage is executed, 258 · Ignatius of Antioch writes seven letters on the way to his death, c. 107 to 117

More about Episcopacy

Ignatius already assumes a single bishop with presbyters and deacons around him. Cyprian argued that the bishops together hold the church's unity. Whether the arrangement is divinely instituted or a practical development is one of the oldest questions between the churches.

Cyprian of Carthage · Ecclesiology · Ignatius of Antioch

Eternal generation Doctrine

The Son is begotten of the Father eternally. No before, no beginning.

On the timeline: Origen writes On First Principles and Against Celsus, c. 230 to 250

More about Eternal generation

The answer to the Arian claim that begotten has to mean a start. Human begetting happens in time and produces a separate being. Divine begetting does neither. The Son is always Son and the Father is always Father, and neither of them becomes so.

Arianism · Homoousios · Origen of Alexandria · The Trinity

Evangelicalism Movement

A transatlantic Protestant movement marked by conversion, the Bible, the cross and activism.

On the timeline: The Lausanne Covenant, 1974 · The Evangelical Revival and the Great Awakening, c. 1730 to 1760

More about Evangelicalism

David Bebbington's four marks, conversionism, biblicism, crucicentrism and activism, are still the standard description. It grew out of the eighteenth century revivals, and it runs across denominations rather than being one.

Jonathan Edwards · John Wesley

Filioque Controversy

And from the Son. A phrase the west added to the creed and the east never accepted.

On the timeline: The First Council of Constantinople, 381 · The East and West Schism, 1054

More about Filioque

Does the Spirit proceed from the Father, or from the Father and the Son? There are two disputes here, not one. The east objects to the doctrine, holding that the Father alone is the source within the Trinity. And it objects to the procedure, because the west amended an ecumenical creed without an ecumenical council. Rome has since clarified that it does not mean the Spirit has two sources, and the creed is used without the phrase in some Catholic worship. It remains unresolved.

Pneumatology · The Trinity

The fourfold gospel Doctrine

The church's decision to keep four accounts rather than blend them into one.

On the timeline: The four gospels reach their written form, c. 65 to 100

More about The fourfold gospel

Irenaeus defended it with an argument from the four winds and the four corners of the earth that few now find persuasive. The decision itself has worn far better. Four portraits that differ in detail and agree in substance are harder to explain away than one smoothed narrative.

Canon · Irenaeus of Lyons

Free will Doctrine

Whether, and in what sense, a person can choose God.

On the timeline: The Pelagian controversy, c. 411 to 431

More about Free will

Almost nobody in the tradition denies that people choose. The argument is about whether a will bent away from God can turn itself back. Augustine said no, Pelagius said yes, Erasmus and Luther fought it out again, and Arminius and Dort after them. Separating freedom from coercion and freedom of inclination takes most of the heat out of it.

Desiderius Erasmus · Grace · Martin Luther · Pelagianism · Predestination

Gnosticism Controversy

Salvation by secret knowledge, and a creation that should never have happened.

On the timeline: Irenaeus writes Against Heresies, c. 180

More about Gnosticism

A loose family rather than one system. What they share is a lesser and hostile creator god, matter as the problem, and an elite saved by knowing things. Irenaeus saw that the real issue was the story. The gnostics used Christian words inside a completely different plot.

Docetism · Irenaeus of Lyons · Marcionism · The rule of faith

Gospel Doctrine

Good news. Originally the announcement of a royal victory, or a new emperor.

More about Gospel

The word euangelion was already in public use for imperial proclamations before the church took it. Applying it to a crucified provincial was a deliberate provocation. It names the announcement first, and only later became the label for the four books that carry it.

The fourfold gospel · Kerygma · The kingdom of God

Grace Doctrine

God's favour, given rather than earned.

On the timeline: The conversion of Augustine, 386 · The Second Council of Orange, 529 · The Pelagian controversy, c. 411 to 431

More about Grace

The word carries a lot of weight and it does not always carry the same weight. For Augustine it is the power that heals a damaged will. For the medieval schoolmen it can be something infused. For the Reformers it is above all God's disposition towards sinners. Read it carelessly across periods and you will confuse yourself endlessly.

Augustine of Hippo · Justification · Pelagianism · Prevenient grace

The Great Commission Practice

The command at the end of Matthew to make disciples of all nations.

On the timeline: William Carey and the modern missionary movement, 1792

More about The Great Commission

Its force was disputed. Some held it had been discharged by the apostles, which is the view Carey wrote against in 1792. Read alongside Genesis 1:28 it also looks like the renewal of an original commission to fill the earth, which is how biblical theology tends to take it.

Biblical theology · Mission

Higher criticism Method

Historical study of a biblical text's sources, authorship, date and setting.

On the timeline: The rise of historical criticism, c. 1780 to 1900

More about Higher criticism

Different from lower or textual criticism, which works out the wording. The methods themselves are ordinary historical tools. The controversy is about the assumptions they are sometimes carried out with, particularly where the conclusion about what can happen in history is fixed in advance.

The documentary hypothesis · The quest for the historical Jesus · Textual criticism

The hypostatic union Doctrine

The two natures of Christ meet in one person. No mixing, no separating.

On the timeline: The Council of Chalcedon, 451 · The Council of Ephesus, 431

More about The hypostatic union

Chalcedon's four adverbs do the work. Without confusion, without change, without division, without separation. The first two protect the distinction of the natures, the second two protect the unity of the person. The definition is a fence, not an explanation.

The Chalcedonian Definition · Hypostasis · The Incarnation · Monophysitism · Nestorianism

Iconoclasm Controversy

The rejection of religious images, and the fight over them in the eastern church.

On the timeline: The iconoclast controversy, c. 726 to 843

More about Iconoclasm

John of Damascus answered that the incarnation changes the terms. God who could not be pictured has taken visible flesh, so refusing images comes close to denying that. The Second Council of Nicaea in 787 permitted them, drawing a line between veneration and the worship due to God alone. The Reformed churches later rejected images again, arguing from the second commandment rather than from christology. That is a different objection and it needs answering on its own terms.

The Incarnation · John of Damascus

Imputation Doctrine

Something credited to an account that did not earn it.

More about Imputation

In Reformation theology, Adam's sin is imputed to humanity and Christ's righteousness to the believer. Critics call it a legal fiction. Defenders answer that it is no fiction if the person is genuinely united to Christ, which is why imputation and union with Christ belong together.

Justification · Original sin · Union with Christ

The Incarnation Doctrine

God the Son took a full human nature and did not stop being God.

On the timeline: The iconoclast controversy, c. 726 to 843

More about The Incarnation

From the Latin for enfleshing. The claim is not that God appeared as a man, nor that a man was promoted to divinity, but that one person exists in two complete natures. Every christological heresy of the first five centuries is a simplification of this in one direction or the other.

Arianism · The Chalcedonian Definition · Docetism · The hypostatic union · Logos

Indulgence Practice

Remission of temporal penalty for sin, and the immediate cause of the Reformation.

On the timeline: Luther posts the Ninety Five Theses, 1517

More about Indulgence

In theory an indulgence remits penalty, not guilt, and never forgiveness itself. In practice, by 1517, it was being sold with promises about souls in purgatory. Luther's theses attack the sale and the theology behind it. Trent later abolished the sale and kept the doctrine.

Martin Luther · Penance · 1545 to 1563

Justification Doctrine

Being declared right with God.

On the timeline: The conversion of Saul of Tarsus, c. 33 to 36 · Luther posts the Ninety Five Theses, 1517 · The Council of Trent, 1545 to 1563

More about Justification

The central Reformation dispute. Is it a legal declaration on the basis of Christ's righteousness credited to the believer, or the act by which God makes a person actually righteous, begun at baptism and increased through life? Trent and the Reformers meant different things by the word, which is part of why they could not agree. In 1999 the Lutheran World Federation and the Catholic Church signed a Joint Declaration concluding that the condemnations of the sixteenth century no longer apply to the other side's teaching as it is now stated. Not everyone on either side accepts that this settles it.

Imputation · Martin Luther · Penal substitution · Sanctification

The kingdom of God Doctrine

God's reign, announced by Jesus as arriving in his own ministry.

More about The kingdom of God

The central theme of Jesus' preaching in the synoptics. The scholarly consensus of the last century is that it is both present and future, already begun and not yet finished, which is why the New Testament can speak of it in both tenses without embarrassment.

Eschatology · Parousia

The lapsed Controversy

Those who denied the faith under persecution and later wanted to come back.

On the timeline: The Decian persecution and the lapsed, 250 to 251

More about The lapsed

The hardest pastoral problem of the third century, by a distance. Some had sacrificed. Some had merely bought a certificate. Some had handed over books. Whether and how they could be restored split churches, and it generated the doctrine of penance.

Cyprian of Carthage · Novatianism · Penance

Law and gospel Doctrine

The relation between God's command and God's promise.

On the timeline: The Council of Jerusalem, c. 49

More about Law and gospel

Luther made the distinction a key for reading the whole Bible, arguing that confusing the two destroys assurance. The Reformed tradition adds a third use of the law, as a guide for the Christian life, where Luther pressed hardest on its work of exposing sin. Both are trying to keep grace free without making obedience optional.

Liberal theology Movement

Rebuilding Christian belief on religious experience and modern knowledge.

On the timeline: Schleiermacher and liberal theology, 1799 to 1830

More about Liberal theology

Begins with Schleiermacher and runs through the nineteenth century. The aim was to keep faith credible to educated moderns. Barth's judgement, formed by watching his teachers endorse the war in 1914, was that it had ended up talking about humanity in a loud voice.

Marcionism Controversy

The God of the Old Testament is a different and lesser god from the Father of Jesus.

On the timeline: Marcion is expelled from the church at Rome, c. 144

More about Marcionism

Marcion cut the Old Testament away and pruned the New down to a shortened Luke and ten letters of Paul. The church's rejection of him is one of the most consequential decisions it ever made. The temptation he represents has never gone away.

The marks of the church Doctrine

One, holy, catholic and apostolic. The four adjectives in the creed.

More about The marks of the church

The Reformers added a second set of tests for a true church. The word rightly preached and the sacraments rightly administered, with discipline sometimes as a third. Both lists are attempts to answer the same question, which is how you tell.

Creed · Donatism · Ecclesiology

Martyrdom Practice

From the Greek for witness. Dying rather than denying.

On the timeline: The fire of Rome and the first imperial persecution, 64 · The martyrdom of Perpetua and Felicity, 203 · The martyrdom of Polycarp, c. 155 or 167

More about Martyrdom

The early church treated martyrdom as the fullest form of testimony, and read the martyr's death as conformity to Christ's. It also created problems. The prestige of confessors who survived complicated the question of who could forgive the lapsed, and some enthusiasts had to be talked out of volunteering.

The lapsed · Polycarp of Smyrna

Mission Practice

The sending of the church, and increasingly understood as God's sending before it is ours.

On the timeline: William Carey and the modern missionary movement, 1792 · The Lausanne Covenant, 1974

More about Mission

The phrase missio Dei makes the point that mission is God's activity, which the church joins, rather than a programme the church runs. The modern missionary movement from Carey onward is why the world church looks the way it does. Its entanglement with colonial power is part of that account.

The Great Commission · World Christianity

Modalism Controversy

Father, Son and Spirit are three modes of one person, not three persons.

More about Modalism

Also called Sabellianism, or in the west patripassianism, because it means the Father suffered on the cross. It is the most common accidental heresy in ordinary preaching. The water, ice and steam illustration falls straight into it, and the clover and the egg fall into the opposite error of making the persons into parts.

Persona · The Trinity

Monasticism Practice

Withdrawal for prayer, work and discipline, alone or in community.

On the timeline: The Rule of St Benedict, c. 540

More about Monasticism

It began in the Egyptian desert with Antony and the desert fathers, partly as a substitute for martyrdom once persecution ended. Benedict's rule shaped the western form. Monasteries carried literacy, agriculture, medicine and libraries through the collapse of the western empire.

Antony of Egypt · Benedict of Nursia

Monophysitism Controversy

Christ has one nature, the human absorbed into the divine.

On the timeline: The Council of Chalcedon, 451

More about Monophysitism

The opposite error to Nestorianism, and condemned at Chalcedon. The label gets applied loosely and often unfairly. The Oriental Orthodox churches prefer miaphysite, one united nature out of two, and modern dialogue has concluded that a lot of the split was linguistic.

The Chalcedonian Definition · Cyril of Alexandria · The hypostatic union

Monothelitism Controversy

Christ has two natures but only one will. A seventh century compromise.

On the timeline: Maximus the Confessor dies in exile, 662

More about Monothelitism

Proposed to win back the churches that had rejected Chalcedon. Maximus the Confessor argued that a nature without a will is not a nature, so a Christ with no human will has not truly become human, and Gethsemane stops making sense. He was mutilated for saying so, and vindicated after his death.

Neo-orthodoxy Movement

The twentieth century recovery of revelation, against liberal theology.

On the timeline: Barth's commentary on Romans, 1919, revised 1922

More about Neo-orthodoxy

A label Barth disliked. The instinct behind it is that theology has to begin with God's self-disclosure rather than with human religiosity, and it went back to the Reformers and the creeds while still accepting critical scholarship. Barth, Brunner, and differently, Bonhoeffer.

Karl Barth · Dietrich Bonhoeffer · Liberal theology · Revelation

Nestorianism Controversy

Christ is so distinguished into two natures that he risks becoming two subjects.

On the timeline: The Council of Ephesus, 431

More about Nestorianism

Nestorius objected to Theotokos and wanted the divine and the human kept strictly apart. Whether the historical Nestorius held what was condemned in his name is genuinely disputed. The Church of the East, labelled Nestorian for centuries, has reached agreement with Rome on the substance in modern times.

The hypostatic union · Nestorius · Theotokos

The Nicene Creed Doctrine

The creed most churches say on a Sunday. Nicaea in 325, expanded at Constantinople in 381.

More about The Nicene Creed

Strictly it is the Niceno-Constantinopolitan Creed. The 325 version stopped abruptly after the Holy Spirit and added a set of anathemas against Arian phrases. The 381 revision dropped the anathemas and filled out the article on the Spirit. The filioque is a later western addition and is not in the original text.

Original sin Doctrine

Human beings are born into a condition they cannot fix by trying harder.

On the timeline: The conversion of Augustine, 386 · The Pelagian controversy, c. 411 to 431

More about Original sin

Augustine's formulation, worked out against Pelagius. It is not the claim that infants are guilty of particular crimes, but that the will is disordered from the start. Eastern theology tends to speak of inherited mortality and corruption rather than inherited guilt, and that is a real difference.

Augustine of Hippo · Free will · Grace · Pelagianism

Orthodoxy Method

Right belief, or right worship. Both meanings are there in the Greek.

On the timeline: The East and West Schism, 1054

More about Orthodoxy

Used for correct doctrine generally, and as the name of the eastern churches. The two senses are connected, because the east has tended to treat worship rather than propositional definition as the thing that carries the faith.

Dogma · Liturgy

Papal infallibility Doctrine

Defined at the First Vatican Council in 1870, and narrower than people assume.

On the timeline: The First Vatican Council, 1869 to 1870

More about Papal infallibility

It applies to formal definitions on faith and morals made by the pope speaking as universal pastor, and it has been invoked explicitly very rarely. It is not a claim that the pope cannot be wrong about anything.

Tradition

Participation Doctrine

Sharing in something that belongs by nature to someone else.

More about Participation

This is the concept doing the heavy lifting in patristic teaching about salvation. A creature can only receive divine life by participation, never possess it by nature. Athanasius' argument against Arius runs straight through it. A Son who himself only participates in God cannot hand participation on to anybody else.

Arianism · Athanasius of Alexandria · Deification · Union with Christ

Pelagianism Controversy

Human beings can obey God by the exercise of their own will.

On the timeline: The Pelagian controversy, c. 411 to 431

More about Pelagianism

Pelagius was a moral reformer appalled by lax Christians. His argument was that God would not command the impossible. Augustine replied that the will itself needs healing before it can want the good at all. The church sided with Augustine, at Carthage and then at Ephesus.

Augustine of Hippo · Grace · Original sin · Pelagius

Penal substitution Doctrine

Christ bears the punishment due to sinners, in their place.

More about Penal substitution

Developed by the Reformers out of earlier substitutionary language, and central to most evangelical accounts of the cross. Critics say it cuts the cross off from the resurrection and can set the Father against the Son. Defenders say the New Testament language of propitiation and curse requires it.

Atonement · Justification · Satisfaction

Penance Practice

How the church deals with serious sin after baptism.

On the timeline: The Decian persecution and the lapsed, 250 to 251 · The Novatianist schism, 251

More about Penance

The third century had no ready answer and nearly split over it. Early practice allowed one restoration after grave sin, and that developed into repeated private confession. The medieval system of confession, absolution and satisfaction is where indulgences eventually grew, which is how the question ended up at 1517.

Cyprian of Carthage · Indulgence · The lapsed · Novatianism

Pentecostalism Movement

Renewal centred on the gifts and the present work of the Spirit.

On the timeline: Azusa Street, 1906

More about Pentecostalism

Usually dated from Azusa Street in 1906, though there were earlier stirrings. With the later charismatic movement inside the historic churches, it is the fastest growing form of Christianity in the world, and overwhelmingly a southern hemisphere one.

Pneumatology · World Christianity

Predestination Doctrine

God's decision about salvation, made before anything else. What that means is the whole argument.

On the timeline: The Synod of Dort, 1618 to 1619 · Calvin publishes the Institutes, 1536, revised to 1559 · The Westminster Confession and Catechisms, 1646 to 1647

More about Predestination

Held in some form by Augustine, Aquinas, Luther and Calvin alike. It is not a Calvinist invention. Arminians hold it too and define it differently, as God's determination to save those who believe. The divisions are over whether election is unconditional or rests on foreseen faith, and whether there is a matching decree of reprobation. Each side says the other cannot account for something. The Reformed say grace must be sovereign or it is not grace. The Arminian says a choice that could not have gone otherwise is not a choice.

Arminianism · John Calvin · Free will · Grace

Prevenient grace Doctrine

Grace that comes first, so that a person can respond at all.

On the timeline: The Second Council of Orange, 529

More about Prevenient grace

From the Latin for going before. The Second Council of Orange affirmed that even the first stirring of faith is God's gift. Wesley made the idea central, arguing that God gives everyone enough grace to be able to respond, which lets him hold real freedom and total dependence at the same time.

Grace · Semi-Pelagianism · John Wesley

The quest for the historical Jesus Controversy

Attempts to reconstruct Jesus by historical method alone.

On the timeline: The rise of historical criticism, c. 1780 to 1900

More about The quest for the historical Jesus

Albert Schweitzer's verdict on the first quest was that each scholar had looked down a deep well and seen his own face. Later quests have been more disciplined, and the third has taken Jesus' Jewishness seriously in a way the first never did.

Higher criticism · Liberal theology

Recapitulation Doctrine

Irenaeus' idea that Christ retraces the whole human story and gets it right.

On the timeline: Irenaeus writes Against Heresies, c. 180

More about Recapitulation

From the Greek anakephalaiosis, summing up under a head, in Ephesians 1:10. Where Adam disobeyed at a tree, Christ obeys at a tree. Christ passes through every stage of a human life and makes each one holy. It is a way of saying that salvation restores and completes creation rather than replacing it.

Atonement · Deification · Irenaeus of Lyons

Renaissance humanism Movement

Back to the sources. Read the classics and the Bible in the languages they were written in.

On the timeline: Erasmus publishes the Greek New Testament, 1516

More about Renaissance humanism

Ad fontes was the slogan. Erasmus applied it to the New Testament and found that the Latin Vulgate did not always match the Greek. Humanism handed the Reformation its tools, even where the humanists themselves would not follow the Reformers.

Desiderius Erasmus · Sola scriptura · Textual criticism

Resurrection Doctrine

Not the survival of the soul. The raising of the body.

On the timeline: The crucifixion and resurrection of Jesus, c. 30 or 33

More about Resurrection

The Christian hope is bodily, and it is corporate, and it has a new creation attached to it. Paul in 1 Corinthians 15 argues that if Christ is not raised then the whole thing collapses, which is an unusually falsifiable claim for a religion to make.

Eschatology · Kerygma

Revelation Doctrine

God making himself known, rather than being worked out from below.

On the timeline: Barth's commentary on Romans, 1919, revised 1922

More about Revelation

The usual distinction is between general revelation, available in creation and conscience, and special revelation in scripture and above all in Christ. Barth's whole project turns on insisting that revelation comes from God's side, which is why he was so hostile to natural theology.

Karl Barth · Logos · Natural theology

The rule of faith Method

A short summary of the Christian story, used as a guide to reading scripture.

On the timeline: Irenaeus writes Against Heresies, c. 180

More about The rule of faith

Irenaeus and Tertullian appeal to it against the gnostics, who could quote scripture freely while telling an entirely different story with it. The rule is not a text set over the Bible. It is the plot of the Bible, held in advance, so that individual verses get read inside it.

Creed · Gnosticism · Hermeneutics · Irenaeus of Lyons

Sanctification Doctrine

Being made holy, over time.

More about Sanctification

The Reformers distinguished it from justification, which happens once and is complete. Keeping the two distinct without separating them is the perennial problem. Calvin's solution was to root both in union with Christ, so that neither can be had without the other.

John Calvin · Justification · Union with Christ

Satisfaction Doctrine

Anselm's account. Sin dishonours God infinitely, and only the God-man can put it right.

On the timeline: Anselm writes Cur Deus Homo, 1098

More about Satisfaction

Anselm argued from the feudal logic of honour and debt. Humanity owes what it cannot pay, God alone can pay it, and the debt is a human one, so whoever pays has to be both. It gets confused with penal substitution constantly, but that is a later and different argument, about punishment rather than honour.

Anselm of Canterbury · Atonement · Penal substitution

Scholasticism Movement

The medieval school method. State the question, list the objections, answer, reply.

On the timeline: Thomas Aquinas writes the Summa Theologiae, 1265 to 1274

More about Scholasticism

A way of working rather than a set of conclusions, and there were Protestant scholastics as well as Catholic ones. Its reputation for hair splitting is mostly unfair. The disputed question format makes you state the strongest case against yourself before you answer it.

Anselm of Canterbury · Thomas Aquinas

Semi-Pelagianism Controversy

The first move towards God is ours, and grace does the rest.

On the timeline: The Second Council of Orange, 529

More about Semi-Pelagianism

A later and polemical label, coined in the sixteenth century, for the moderate position held in southern Gaul by John Cassian and others, who found Augustine's later teaching on predestination unbearable. The Second Council of Orange in 529 rejected the idea that the first move is human, while declining to follow Augustine all the way.

Grace · Prevenient grace

Sola scriptura Method

Scripture alone is the final authority, over councils and popes.

On the timeline: Luther at the Diet of Worms, 1521

More about Sola scriptura

Regularly misunderstood as scripture only, with tradition thrown out. The Reformers quoted the fathers constantly. The claim is about the final court of appeal, not about ignoring everything else. The version that recognises no authority but a private reading of the Bible is a later and different thing.

Confession · Martin Luther · Tradition

Supersessionism Controversy

The view that the church replaces Israel in God's purposes.

On the timeline: The destruction of the Temple, 70

More about Supersessionism

Held in various strengths across Christian history, and a major factor in Christian antisemitism. Romans 9 to 11 is the text that will not let the strongest forms stand. Most careful modern theology talks about the church being grafted in rather than Israel being replaced.

Covenant · Marcionism

Systematic theology Method

Arranging Christian teaching by topic into a coherent whole.

More about Systematic theology

God, creation, humanity, sin, Christ, salvation, church, last things. It asks what the whole of scripture, read together and with the tradition, requires us to say on a given question. The risk is imposing a shape the texts do not have. The risk of not doing it is never saying anything at all.

Biblical theology · Dogma

Temple and sacred geography Method

Reading Eden, the tabernacle, the temple and the new creation as one connected pattern.

On the timeline: The destruction of the Temple, 70

More about Temple and sacred geography

Genesis 1 and 2 divide the world into regions and then fill them. The tabernacle repeats the pattern in miniature. Courtyard, holy place, most holy place. The prophets and then the New Testament read Christ and the church as the true temple. It is one of the clearest examples of biblical theology at work.

Biblical theology · The Incarnation · Typology

Textual criticism Method

Working out what the original wording most likely was, from thousands of copies.

On the timeline: Erasmus publishes the Greek New Testament, 1516

More about Textual criticism

Sometimes called lower criticism. No two ancient manuscripts agree in every detail, so the discipline compares them. The overwhelming majority of variants are spelling and word order. A small number are theologically interesting, and a few passages people know well are almost certainly later additions, including the ending of Mark and the woman taken in adultery. No central doctrine rests on a contested reading, which is a more modest claim than it is usually made to carry.

Canon · Desiderius Erasmus · Higher criticism

Tradition Method

What has been handed on, and what authority it carries.

On the timeline: The Council of Trent, 1545 to 1563

More about Tradition

From the Latin for handing over. Everyone has a tradition. The dispute is whether it stands alongside scripture as a second source, as Trent was read to say, or whether it is the church's accumulated reading of the one source. Newman and the twentieth century ecumenical conversations have narrowed the gap considerably.

The rule of faith · Sola scriptura

The Trinity Doctrine

One God in three persons, and none of the three is a part or a phase of God.

On the timeline: Tertullian writes in Latin, c. 197 to 210

More about The Trinity

The doctrine was not read off a single verse. It was worked out over three centuries as the church tried to say everything the scriptures say about the Father, the Son and the Spirit without contradicting the confession that God is one. The classic formula is one ousia, three hypostases.

Augustine's picture of two communities, defined by two loves, mixed together until the end.

On the timeline: Augustine finishes The City of God, 413 to 426 · Alaric sacks Rome, 410

More about The two cities

The earthly city is built by love of self to the point of contempt for God. The heavenly city by love of God to the point of contempt for self. Neither maps onto any visible institution, and that is the point. The church is not simply the city of God, and the state is not simply its rival.

Views of the eucharist Controversy

What happens in the bread and the wine. The question that kept the Reformation divided.

On the timeline: The Didache, c. 50 to 120

More about Views of the eucharist

Transubstantiation holds that the substance changes while the appearances remain. The eastern churches affirm the change and decline the Aristotelian machinery used to explain it. Luther held a real bodily presence in, with and under the elements. Calvin held a real presence by the Spirit, the believer lifted up to the Christ who is in heaven. Zwingli read the words as signifying, and made the supper the church's public pledge of allegiance rather than a bare memorial. Luther and Zwingli failed to agree at Marburg in 1529 and the Protestant world has been divided here ever since.

The study of the faith as a genuinely global and mostly non-western thing.

On the timeline: The centre of gravity moves south, c. 1970 to now

On the timeline: Anselm writes Cur Deus Homo, 1098

More about Anselm of Canterbury

His ontological argument for the existence of God has been argued over for nine hundred years. Cur Deus Homo reframed the atonement around the satisfaction of honour, and it shaped western thinking about the cross more than any other single book.

Antony of Egypt c. 251 to 356 · Monk

Went into the desert, and accidentally started monasticism.

More about Antony of Egypt

He heard the gospel command to sell everything, did it, and withdrew. Athanasius' Life of Antony became a bestseller across the empire and produced imitators everywhere, Augustine among them. Once persecution ended, the desert became a substitute for martyrdom.

Athanasius of Alexandria · Monasticism

More about Augustine of Hippo

North African, classically trained, nine years a Manichee before he was a Christian, converted at thirty two, bishop for thirty five years. Grace, sin, will, time, memory, the church, the state. Everything the western church argued about afterwards runs through him, including a fair amount he would not have recognised as his.

Clement of Rome fl. c. 96 · Leader of the church at Rome

Wrote the earliest Christian letter we have from outside the New Testament.

On the timeline: 1 Clement, c. 96

More about Clement of Rome

The letter to Corinth steps into a dispute over deposed leaders and argues for order and humility. The letter itself is anonymous. The attribution to Clement comes later. And whether it shows an early Roman primacy or just one large church advising another is still argued.

Legalised Christianity, summoned Nicaea, and changed the church's place in the world for good.

On the timeline: The Edict of Milan, 313 · Constantine at the Milvian Bridge, 312

More about Constantine

His personal faith is debated. He was baptised only on his deathbed, which was normal practice at the time and is weak evidence either way. What is not debatable is the effect. Persecution ended, money and buildings arrived, and the church acquired a relationship with coercive power that it has argued about ever since.

On the timeline: Cyprian of Carthage is executed, 258 · The Novatianist schism, 251

More about Cyprian of Carthage

He led the African church through the Decian persecution and the mess that followed, argued that the bishops together hold the church's unity, and said there is no salvation outside the church. His disputes with Rome over baptism show that early appeals to Roman authority settled nothing by themselves.

Episcopacy · The lapsed · Novatianism

Cyril of Alexandria c. 376 to 444 · Bishop and theologian

Won at Ephesus, and was not gentle about it.

On the timeline: The Council of Ephesus, 431

More about Cyril of Alexandria

His christology, that the one who was born, suffered and died is the divine Word made flesh, was vindicated at Ephesus and underlies Chalcedon. His methods are a genuine stain. He opened the council before the bishops who disagreed with him had arrived, and he spent heavily at the imperial court afterwards to keep the verdict. He expelled the Jewish community from Alexandria after riots. Whether he bears any responsibility for the murder of the philosopher Hypatia is disputed, and the source that accuses him directly is neither neutral nor contemporary. He later signed a formula of reunion with the Antiochenes that conceded more than his own supporters wanted.

Printed the Greek New Testament, then refused to join the Reformation he had helped cause.

On the timeline: Erasmus publishes the Greek New Testament, 1516

More about Desiderius Erasmus

His scholarship exposed the places where the Latin Vulgate had drifted from the Greek. He wanted reform from the inside, and satire rather than schism. He and Luther eventually fought it out in print over the freedom of the will.

Ran a monastery that trained five bishops, and hosted the meeting that decided how the English would keep Easter.

On the timeline: The Synod of Whitby decides for Rome, 664

More about Hilda of Whitby

A Northumbrian noblewoman who became a nun in her thirties, she founded and ruled the double monastery at Whitby, housing both men and women under one abbess, a common pattern in the period. Five of her monks went on to become bishops. The herdsman Caedmon, later credited as the first named poet in English, was brought into the community after she recognised his gift. In 664 she hosted the Synod of Whitby, where the Northumbrian church chose Roman practice over the Ionan tradition on the dating of Easter and the shape of the tonsure, a decision that set the English church's trajectory toward Rome. Almost everything known about her comes from Bede's Ecclesiastical History, written decades later by a monk with his own view of how the story should end.

He presses the reality of Christ's flesh against docetism, and unity around the bishop against fragmentation. He begs the Roman church not to save him. He also gives us the first use of the phrase catholic church.

Irenaeus of Lyons c. 130 to c. 202 · Bishop and theologian

The first great biblical theologian, and the man who beat the gnostics.

On the timeline: Irenaeus writes Against Heresies, c. 180

More about Irenaeus of Lyons

He saw that the gnostics were not so much misquoting scripture as putting it inside a different story, and he answered with the rule of faith. One God, one creation, one redemption, summed up in Christ. His account of recapitulation still generates new work.

Jan Hus c. 1372 to 1415 · Reformer

Burned at Constance, despite a promise of safe conduct.

On the timeline: Jan Hus is burned at Constance, 1415

More about Jan Hus

A Czech preacher influenced by Wycliffe, who attacked corruption among the clergy. His followers pressed for communion in both kinds for the laity, which he endorsed from prison. Luther, accused of being a Hussite, read him afterwards and concluded that he agreed with him.

Martin Luther · John Wycliffe

Jerome c. 347 to 420 · Translator and scholar

Translated the Bible into Latin from the original languages, and quarrelled with nearly everyone.

More about Jerome

The Vulgate was the Bible of the western church for a thousand years. His insistence on translating from the Hebrew raised the question of the apocrypha, and he lost that argument to Augustine at the time. Translators now work from the Hebrew as he wanted, Catholic ones included. The canon question went the other way, and Trent defined the disputed books as scripture.

John Calvin 1509 to 1564 · Reformer, Geneva

A reluctant, systematic Frenchman with more attached to his name than he ever taught.

On the timeline: The Synod of Dort, 1618 to 1619 · Calvin publishes the Institutes, 1536, revised to 1559

More about John Calvin

He wrote the first Institutes at twenty six and revised it for the rest of his life. Whether predestination or union with Christ is the controlling idea is argued among his readers, and so is whether his successors developed him or distorted him. He did teach reprobation as well as election. In the trial of Michael Servetus he gave evidence for the prosecution and pressed for conviction, though the sentence was the city council's, and he asked without success for beheading rather than burning.

Predestination · Sanctification · Union with Christ

John Chrysostom c. 347 to 407 · Preacher and bishop

Golden mouth. The greatest preacher of the ancient church, and exiled for saying too much.

More about John Chrysostom

An Antiochene, so his exegesis stays close to the plain sense. His sermons on Matthew, John and the Pauline letters are still read for their pastoral seriousness. He was driven out of Constantinople for criticising the imperial court and died in exile. His sermons against the Jews of Antioch are violent even by the standards of the period, and they were put to terrible use long afterwards.

Exegesis · Liturgy

John of Damascus c. 675 to 749 · Monk and theologian

Defended icons, and summed up the whole eastern tradition to that point.

On the timeline: The iconoclast controversy, c. 726 to 843

More about John of Damascus

His argument about images turns on the incarnation. God who could not be depicted has taken visible flesh, so refusing images is a way of being uneasy about that. His Exact Exposition of the Orthodox Faith is often taken as the close of the patristic age in the east.

John Wesley 1703 to 1791 · Evangelist and organiser

Rode a quarter of a million miles preaching, and organised what became Methodism.

On the timeline: The Evangelical Revival and the Great Awakening, c. 1730 to 1760

More about John Wesley

An Anglican priest to the end, though his movement left the church after he died. He held prevenient grace and Christian perfection together, and his genius was organisational as much as theological. His brother Charles wrote the hymns.

Arminianism · Evangelicalism · Prevenient grace

John Wycliffe c. 1328 to 1384 · Theologian and reformer

Argued for scripture in English, and had his bones dug up and burned for it.

On the timeline: The Wycliffe Bible, c. 1382

More about John Wycliffe

He attacked clerical wealth, questioned transubstantiation, and set his circle to translating the Bible into English from the Latin. He was condemned decades after his death, when his remains were exhumed and thrown into the river Swift.

Jan Hus · Vernacular

Jonathan Edwards 1703 to 1758 · Pastor and theologian

America's most formidable theologian, and far more than the one famous sermon.

On the timeline: The Evangelical Revival and the Great Awakening, c. 1730 to 1760

More about Jonathan Edwards

He is remembered for Sinners in the Hands of an Angry God, which misrepresents him badly. His serious work is on the nature of true religious affections, and on beauty as a category in theology. He owned slaves, which his admirers were slow to say out loud. He was dismissed by his own congregation and died shortly after taking up a college presidency.

Evangelicalism · Predestination

Julian of Norwich c. 1343 to after 1416 · Anchoress and mystic

An anchoress who received sixteen visions in a few hours during a near fatal illness, and spent decades writing out what they meant.

More about Julian of Norwich

An anchoress attached to a church in Norwich, where she lived enclosed for decades. Julian is probably not even her own name. It most likely comes from the church of St Julian where she was walled in, and nothing certain is known of her life before that. During a severe illness in 1373 she received sixteen visions of Christ's passion in the course of a few hours. She wrote them up twice, a short text soon afterward and a much longer, more theologically developed one perhaps twenty years later. The Long Text includes the disputed image of Christ as mother, and the repeated assurance that all shall be well, set alongside a serious account of sin rather than instead of one. It is usually called the earliest surviving book in English by a woman, though that claim, like the dating and authorship of the two texts, rests on evidence that is not fully settled.

Justin Martyr c. 100 to c. 165 · Apologist and martyr

A working philosopher who kept the trade after he converted, and died for the faith.

On the timeline: Justin Martyr writes the First Apology, c. 155

More about Justin Martyr

He argued to the emperor that Christians are good citizens, and that whatever is true in philosophy comes from the Word who sows seeds of truth everywhere. His First Apology holds the earliest full description of a Sunday service we have.

Apologist · Logos

Karl Barth 1886 to 1968 · Theologian

A village pastor who broke liberal theology and spent the rest of his life rebuilding.

On the timeline: The Barmen Declaration, 1934 · Barth's commentary on Romans, 1919, revised 1922

More about Karl Barth

His Romans commentary insisted that God is not the highest human value but the one who addresses us from outside. He drafted Barmen against the Nazified church. The Church Dogmatics ran past six million words and was still unfinished when he died.

Neo-orthodoxy · Revelation

Leo the Great d. 461 · Bishop of Rome

His Tome gave Chalcedon its language, and he talked Attila out of Rome.

More about Leo the Great

The Tome of Leo states the two natures in one person with unusual clarity for a document written in the heat of a dispute. The bishops at Chalcedon are reported to have said that Peter had spoken through Leo, which the west has quoted ever since.

Macrina the Younger c. 327 to 379 · Teacher and monastic founder

Taught her famous brothers everything, and left nothing of her own in writing.

More about Macrina the Younger

Sister of Basil of Caesarea and Gregory of Nyssa, and by their account the one who shaped them both. She turned the family estate at Annisa into a monastic community. In his dialogue On the Soul and the Resurrection, Gregory presents her as the calm authority instructing him on death and resurrection, from her own deathbed. Almost everything known about her comes from Gregory's Life of Macrina, a hagiographic text written by a grieving and devoted brother, so the historical woman is harder to recover than the portrait. Even allowing for that, the portrait is substantial enough that she is sometimes called the fourth Cappadocian.

Marcion of Sinope c. 85 to c. 160 · Teacher, expelled

Tried to cut the Old Testament away from Christianity, and was thrown out for it.

More about Marcion of Sinope

He held that the creator God of the Hebrew scriptures was a lesser being than the Father of Jesus, and he produced his own shortened canon. Provoking the church into stating what it did receive may be his largest unintended contribution.

Canon · Marcionism

Martin Luther 1483 to 1546 · Reformer

An anxious monk who found assurance in Romans and broke the western church.

On the timeline: Jan Hus is burned at Constance, 1415 · Luther posts the Ninety Five Theses, 1517 · Luther at the Diet of Worms, 1521

More about Martin Luther

Justification by faith alone, the priesthood of all believers, the Bible in German, and a body of hymns still sung. He was also capable of appalling writing about Jews late in life, above all On the Jews and Their Lies in 1543, which the Lutheran churches have had to confront directly.

Justification · Law and gospel · Sola scriptura

Maximus the Confessor c. 580 to 662 · Monk and theologian

Lost his tongue and his right hand for insisting Christ has a human will.

On the timeline: Maximus the Confessor dies in exile, 662

More about Maximus the Confessor

His argument is that a nature without a will is not a nature, so a Christ with no human will has not truly become human, and Gethsemane becomes a performance. He was mutilated and exiled, and vindicated by a council nineteen years after he died.

Deification · Dyothelitism · Monothelitism

Nestorius c. 386 to c. 451 · Patriarch of Constantinople, deposed

Objected to calling Mary God-bearer, and lost his see over it.

On the timeline: The Council of Ephesus, 431

More about Nestorius

He was trying to protect the full humanity of Christ and the impassibility of God. Whether he actually held the doctrine condemned in his name is genuinely disputed. A long defence he wrote in exile, the Bazaar of Heracleides, survived in Syriac and reached western scholars early in the twentieth century, and it has complicated the picture considerably.

Nestorianism · Theotokos

Origen of Alexandria c. 185 to c. 253 · Theologian and exegete

The most learned and the most controversial Christian of the third century.

On the timeline: Origen writes On First Principles and Against Celsus, c. 230 to 250

More about Origen of Alexandria

He wrote the first systematic theology, defended the faith against Celsus, and produced a vast body of work on scripture. Some of his speculations were condemned centuries after he died. Almost every later father, including his critics, used tools he had made.

Allegory · Eternal generation

Paul c. 5 to c. 65 · Apostle

Persecutor turned apostle, and the earliest Christian writer we can read.

On the timeline: The conversion of Saul of Tarsus, c. 33 to 36

More about Paul

A Pharisee of the diaspora. Educated, a Roman citizen, fluent in the scriptures he had been using against the church. His letters come before the gospels, and they are the foundation of most later theology of grace, the law and union with Christ. He is also the most consistently misread writer in the New Testament.

Justification · Union with Christ

Pelagius c. 354 to c. 420 · British ascetic and teacher

Argued that people can obey God if they choose to, and was condemned.

More about Pelagius

He was a moral reformer, appalled by lax Roman Christians who blamed their weakness on their nature. His logic was that God does not command the impossible. Some of his own writing survives, including a commentary on Paul, but he is mostly read through Augustine, which is not a neutral source.

Augustine of Hippo · Free will · Pelagianism

Philip Melanchthon 1497 to 1560 · Reformer and scholar

Luther's calmer colleague, and the writer of the Lutheran movement's first systematic theology.

On the timeline: The Augsburg Confession, 1530

More about Philip Melanchthon

He drafted the Augsburg Confession and the Loci Communes, and he pressed for agreement where Luther pressed for clarity. His willingness to compromise made him suspect to hardliners on his own side once Luther was dead.

Confession · Martin Luther

Polycarp of Smyrna c. 69 to c. 155 or 167 · Bishop and martyr

A living link back to the apostolic generation, burned as an old man.

On the timeline: The martyrdom of Polycarp, c. 155 or 167

More about Polycarp of Smyrna

Irenaeus says he was taught by John. The account of his death is usually taken as the earliest martyr act we have. His reply to the demand that he curse Christ, that he has served him eighty six years and Christ has never wronged him, is the line everybody remembers.

The Apostolic Fathers · Martyrdom

Teresa of Avila 1515 to 1582 · Carmelite nun, reformer and mystic

A nun who reformed her own order and wrote her visions down knowing the Inquisition was reading over her shoulder.

More about Teresa of Avila

Granddaughter of a converso forced into public penance by the Inquisition, she entered the Carmelites as a young woman. She later led a reform, the Discalced Carmelites, back toward stricter poverty and prayer. She described her experience of prayer and ecstatic visions in The Interior Castle, and in an autobiography written partly because her confessors ordered it and partly to defend herself. Women who claimed direct experience of God were viewed with particular suspicion in sixteenth century Spain. She was investigated more than once by the Inquisition, and associates close to her were tried by it, though she herself was never condemned. In 1970 she became one of the first two women named a Doctor of the Church.

Tertullian c. 155 to c. 220 · Theologian, North Africa

Gave the Latin west much of its theological vocabulary, then left the mainstream church.

On the timeline: Tertullian writes in Latin, c. 197 to 210

More about Tertullian

He coined or fixed trinity, person and substance in Latin, and asked what Athens has to do with Jerusalem while using rhetorical training from Athens to ask it. He ended up among the rigorist Montanists, which fits his temperament.

Persona · The Trinity

Thomas Aquinas 1225 to 1274 · Theologian

Put Aristotle to work for Christian theology on a scale nobody had attempted.

On the timeline: Thomas Aquinas writes the Summa Theologiae, 1265 to 1274

More about Thomas Aquinas

Grace does not destroy nature but perfects it, and reason can take you some way before revelation is needed. The Summa was left unfinished after an experience he would only describe by saying that everything he had written looked like straw.

Analogy · Natural theology · Scholasticism

Thomas Cranmer 1489 to 1556 · Archbishop of Canterbury

Gave the English church its prayer book, recanted under pressure, then burned his hand first.

On the timeline: The Book of Common Prayer, 1549, revised 1662

More about Thomas Cranmer

His liturgical prose is among the finest in the language, and it was built to be said aloud over and over without wearing out. Under Mary he recanted several times, then withdrew the recantations at the stake and held his right hand in the fire.

William Tyndale c. 1494 to 1536 · Translator

Translated the New Testament into English from the Greek, and was executed for it.

On the timeline: The King James Bible, 1611 · Tyndale's English New Testament, 1526

More about William Tyndale

His English is so good that much of the King James Version simply keeps it. He worked in exile and in hiding. Strangled and burned near Brussels, praying that God would open the king of England's eyes, which within three years the king's own Bible effectively did.
