The Field of Study
Two thousand years is too long a story to hold in the head without a spine to hang it on. This page is that spine: a chronology of the Christian church from the Ascension to the present — the councils and the deserts, the missionaries going east before they went west, the great tearings and the great awakenings — each entry small enough to read in a breath, the whole long enough to see the shape. From here, single events will grow into pages of their own; the timeline is the trunk they will branch from.

❉
The Apostolic Age
c. 30–100The eyewitness generation — from the empty tomb to the death of the last apostle.
c. 30/33
Crucifixion and Resurrection of Jesus in Jerusalem under Pontius Pilate — the event every later date on this page counts from.
c. 30/33 · 40 days on
The Ascension: the risen Jesus, having taught his disciples forty days, is taken up before their eyes on the Mount of Olives, promising the Spirit and commanding witness “to the end of the earth” (Acts 1).
c. 30/33 · 50th day
Pentecost: the Spirit descends on the disciples in wind and fire; Peter preaches, three thousand are baptized, and the church is born as a praying, breaking-bread community in Jerusalem (Acts 2).
c. 34–36
Saul of Tarsus meets the risen Jesus on the Damascus road — the persecutor becomes the apostle to the nations.
c. 49
The Council of Jerusalem (Acts 15) settles that Gentiles enter the church without the Mosaic yoke — the pattern for every later council: “it seemed good to the Holy Spirit, and to us.”
c. 52
By the ancient tradition of the Mar Thoma churches, the apostle Thomas lands on the Malabar coast of India — the faith reaching the subcontinent a generation before most of Europe heard of it. He is venerated as martyred near Chennai c. 72.
64–67
Nero’s persecution after the Great Fire of Rome. By early and unanimous tradition, Peter is crucified in Rome and Paul beheaded on the Ostian Way; a later tradition (the Acts of Peter, c. 190) adds that Peter asked to be crucified head-down.
70
Rome destroys Jerusalem and the Temple. The church’s center of gravity begins its long migration outward — to Antioch, Alexandria, Ephesus, Rome.
c. 95–100
The apostolic age closes: John, last of the Twelve, dies at Ephesus; the Revelation and the final New Testament writings are complete.
❉
The Church of the Martyrs
100–313Illegal, scattered, and growing — the centuries of blood and brilliant argument.
c. 107
Ignatius of Antioch, condemned to the beasts, writes seven letters on his march to Rome — the first surviving use of the phrase “the catholic church,” and the earliest clear picture of bishop, presbyters, and deacons.
c. 155
Polycarp of Smyrna, John’s disciple, burned after eighty-six years a Christian: “Eighty and six years have I served him, and he never did me wrong.” In the same years Justin Martyr writes the first great defenses of the faith to the emperor.
c. 180
Irenaeus of Lyons writes Against Heresies against the Gnostics — the rule of faith, the four Gospels, and “the glory of God is a living man.”
c. 197–220
Tertullian writes in Carthage — the first great Latin theologian, coiner of the word Trinitas: “the blood of the martyrs is seed.”
203
Perpetua and Felicity, a young mother and an enslaved woman martyred beside her, die in the Carthage arena; Perpetua’s prison diary survives — among the earliest Christian writing by a woman.
c. 215–254
Origen of Alexandria teaches, tortured in the Decian persecution and dying of it — the ancient world’s greatest biblical scholar (the Hexapla, On First Principles), brilliant, controversial, and foundational.
250 · 303
The empire-wide persecutions: Decius demands universal sacrifice; Diocletian’s Great Persecution burns Scriptures and churches. The questions they raise — what to do with those who lapsed — will shape the church for a century.
c. 270
Anthony of Egypt sells everything and walks into the desert. The monastic movement is born; the Desert Fathers and Mothers follow, and Athanasius’s Life of Antony (c. 357) will carry the desert’s fire across the world.
❉
The Imperial Church & the Seven Councils
313–787From outlaw sect to imperial faith — and the seven great definitions East and West still share (the councils, one by one).
301 · 313
Armenia becomes the first Christian kingdom (tradition: 301, Gregory the Illuminator); Constantine’s Edict of Milan (313) ends the persecutions across the empire.
325
Nicaea I — the first Ecumenical Council: against Arius, the Son confessed homoousios, of one essence with the Father; the Creed begun.
330
Constantine consecrates Constantinople — the empire’s center, and with it the church’s institutional weight, moves east, where it will remain for a millennium.
367
Athanasius — exiled five times for Nicaea — lists in his Easter letter the 27 books of the New Testament exactly as we have them.
381
Constantinople I: the divinity of the Holy Spirit confessed; the Nicene-Constantinopolitan Creed completed — the creed still said today.
386 · 405
Augustine converts in a Milan garden (“take up and read”) — the West’s greatest theologian; Jerome completes the Latin Vulgate, the West’s Bible for a thousand years.
410
Rome falls to Alaric (Augustine answers with The City of God); in the same year, the Persian church organizes at the Synod of Seleucia-Ctesiphon — the Church of the East, which will carry the gospel along the Silk Road.
431 · 451
Ephesus vindicates the Theotokos; Chalcedon defines one Christ in two natures — and the churches that cannot receive it (Coptic, Ethiopian, Armenian, Syriac) become the Oriental Orthodox — the first great lasting division within the imperial church (the Church of the East had already gone its own way after Ephesus).
c. 529
Benedict of Nursia founds Monte Cassino and writes his Rule — “a school for the Lord’s service” — the charter of Western monasticism, preserver of learning through the dark centuries.
537 · 563
Hagia Sophia is consecrated in Constantinople; Columba sails to Iona, and Celtic monks begin re-evangelizing northern Europe (Augustine of Canterbury reaches England, 597).
553 · 680–681
Constantinople II and Constantinople III — the fifth and sixth councils: the deepened reading of Chalcedon, and the two wills of Christ against monothelitism.
635 · 638
The Church of the East’s monk Alopen reaches Chang’an, China (commemorated on the Xi’an stele of 781) — while Jerusalem falls to the new armies of Islam, soon followed by Alexandria and Antioch: three of the five patriarchates under Muslim rule.
787
Nicaea II, the seventh and last council East and West share: icons vindicated — veneration passes to the prototype; worship belongs to God alone.
❉
Two Worlds Drifting Apart
800–1204Franks and Byzantines, Slavs and Athonites — one church becoming two civilizations.
800
The pope crowns Charlemagne emperor in Rome on Christmas Day — a rival “Roman Empire” in the West, and a deepening estrangement from Constantinople.
863
Cyril and Methodius go to the Slavs with an alphabet and the liturgy in their own tongue — the missionary principle that Scripture and worship belong in the vernacular.
963
Athanasius the Athonite founds the Great Lavra on Mount Athos — the Holy Mountain becomes, and remains, the beating heart of Orthodox monasticism.
988
The Baptism of Rus’: Prince Vladimir of Kiev, his envoys undone by the Liturgy in Hagia Sophia (“we knew not whether we were in heaven or on earth”), brings the Slavic north into the Byzantine world.
1054
The Great Schism: mutual excommunications in Constantinople — papal authority and the filioque the fault lines — and the church parts into East and West. The date is symbolic; the estrangement was centuries in the making, and centuries in the hardening.
1095 · 1204
The Crusades begin (1095); the Fourth Crusade’s sack of Constantinople (1204) is the wound that made the Schism effectively irreversible — though crusading itself grinds on to Acre’s fall (1291) and beyond.
❉
The Medieval Church
1200–1453Friars and schoolmen, hesychasts and first reformers — the high Middle Ages and their unraveling.
1209–1226
Francis of Assisi strips off his wealth and marries Lady Poverty; with Dominic’s preachers, the friars take the gospel back to the streets.
1274
Thomas Aquinas dies en route to a reunion council, the Summa Theologiae unfinished — “all I have written seems to me like straw.” Scholasticism’s summit.
1330s–1351
The Hesychast controversy: Barlaam of Calabria ridicules the Athonite monks’ unceasing prayer of the heart and their claim to see the divine light; St. Gregory Palamas answers in the Triads in Defense of the Holy Hesychasts — God is unknowable in his essence yet truly encountered in his uncreated energies, the light the apostles saw on Tabor. The councils of Constantinople (1341, 1347, 1351) vindicate Palamas — the East’s last great dogmatic definition, and the theological charter of Athonite prayer to this day.
1384 · 1415
The first reformers: John Wycliffe dies, his followers carrying an English Bible; Jan Hus is burned at Constance — a century before Luther, holding much of Luther’s case.
1453
Constantinople falls to Mehmed II; the Liturgy in Hagia Sophia is interrupted, tradition says, mid-service. Greek scholars stream west with their manuscripts — feeding the Renaissance that will feed the Reformation. Within decades, Moscow will begin to style itself the Third Rome.
c. 1455
Gutenberg prints the Bible. Within a lifetime, print will make every reform movement unstoppable.
❉
Reformation & Counter-Reformation
1517–1648The Western church breaks open — and every side burns with reform.
1517
The Reformation begins: Luther’s Ninety-five Theses against the indulgence trade. Within five years — excommunication, the Diet of Worms (and its legendary “here I stand”), and a German New Testament.
1525 · 1534
The Reformation fractures as it spreads: the first Anabaptists baptize one another in Zurich (the free-church stream); Henry VIII’s Act of Supremacy detaches England.
1527
The Anabaptist witness sealed: Felix Manz is drowned in Zurich’s river Limmat — a Protestant martyred by Protestants — and the Schleitheim Confession (Michael Sattler, himself burned months later) fixes the free-church marks: believer’s baptism, nonresistance, separation from the sword.
1536
Menno Simons, a Dutch priest, leaves Rome to shepherd the scattered and hunted Anabaptists — the Mennonites, bearers of the peace-church tradition ever since.
1536–1564
Calvin’s era: the Institutes (1536) and the Geneva reform — the systematic mind of Protestantism, whose heirs would frame the five points at Dort.
1540
Ignatius of Loyola’s Society of Jesus is approved — the Spiritual Exercises, schools across Europe, and missionaries (Xavier to India and Japan) around the globe.
1545–1563
The Council of Trent answers the reformers — the Counter-Reformation: doctrine defined (justification, the sacraments, the canon), abuses pruned, and a reformed, militant Catholicism launched.
1562–1591
The Spanish mystics: Teresa of Ávila reforms Carmel, and John of the Cross — imprisoned by his own order — writes the Dark Night of the Soul: the Counter-Reformation’s interior fire.
1611 · 1618–19
The King James Bible; the Synod of Dort distills Calvinism into the five points this desk examines. The Thirty Years’ War (1618–1648) exhausts confessional Europe into tolerance.
1620 · 1630
The Mayflower Pilgrims covenant together off Cape Cod and plant Plymouth; John Winthrop’s fleet follows with “a city upon a hill” — the Puritan errand that stamps American Christianity with covenant, conscience, and mission.
1636 · c. 1638
Roger Williams, banished from Massachusetts, founds Providence on “soul liberty” and gathers the first Baptist church in America — church and state divorced a century and a half before the First Amendment wrote it down.
❉
Awakenings & Missions
1647–1900After the wars of religion — the religion of the heart, and the gospel to every coast.
1647–1652
George Fox hears “there is one, even Christ Jesus, that can speak to thy condition,” and from Pendle Hill gathers the Religious Society of Friends — the Quakers: the Inner Light, silent waiting worship, and a stubborn peace testimony.
1681 · 1688
William Penn’s “holy experiment”: Pennsylvania founded on liberty of conscience; at Germantown (1688), German-Dutch Quakers of Mennonite background sign America’s first written protest against slavery — a seed John Woolman’s quiet Journal would water a century on.
1693
Jakob Ammann calls the Swiss Brethren to a stricter separation from the world — the Amish, keeping the old ways to this day.
1730s–1740s
The First Great Awakening: Jonathan Edwards in New England, George Whitefield’s open-air preaching — and John Wesley’s heart “strangely warmed” at Aldersgate (1738), from which Methodism spreads.
1793
William Carey sails for India — remembered by the motto “expect great things from God; attempt great things for God” — opening the modern Protestant missionary movement (Judson, Livingstone, Hudson Taylor in his wake).
c. 1795–1840
The Second Great Awakening: camp meetings and revival across America — Cane Ridge, Kentucky (1801), the greatest of them — and out of its ferment, abolitionism and the Black church’s independent denominations (the AME, 1816).
1830 · 1832 · 1844
The young republic’s free religious market births new movements: the Stone-Campbell Restoration (union, 1832) seeking the New Testament church alone; Adventism rising from the Great Disappointment (1844); and, farther from the creeds, the Latter-day Saints (1830).
1833–1892
The Victorian giants: the Oxford Movement re-catholicizes Anglicanism (Newman crosses to Rome, 1845); Spurgeon preaches to London thousands; Dostoevsky gives Orthodoxy its modern voice to the West.
1854 · 1870
Rome defines the Immaculate Conception, and Vatican I defines papal infallibility — the papacy at its doctrinal high-water mark.
1857–1858
The Layman’s Prayer Revival: Jeremiah Lanphier’s noon prayer meeting on Fulton Street multiplies through America’s cities — estimates ran to a million converts on the eve of the Civil War, a revival led not by preachers but by praying laypeople.
❉
The Global Century
1900–nowThe Spirit poured out again, the churches talking again — and the center of gravity moving south.
1906
Azusa Street: revival breaks out under William Seymour, a Black holiness preacher in Los Angeles — the ignition of Pentecostalism, within a century the fastest-growing Christian movement on earth.
1945 · 1947
The manuscript century: the Nag Hammadi library and the Dead Sea Scrolls are found within two years of each other, remaking scholarship of the Bible’s world.
1949
Billy Graham’s Los Angeles crusade makes him the face of modern evangelicalism — six decades, hundreds of millions reached, and a rare evangelical bridge across denominations.
1955–1968
The Black church leads the civil rights movement: from the Montgomery bus boycott to Memphis, Martin Luther King Jr.’s gospel-rooted nonviolence — the “Letter from Birmingham Jail” (1963) a modern epistle — the American church’s most consequential public witness.
1962–1965
Vatican II: Rome’s great aggiornamento — vernacular liturgy, Scripture restored to the center, dialogue with the East (the 1054 anathemas mutually lifted, 1965) and with the churches of the Reformation.
1967–1972
The Jesus Revolution: hippies baptized in the Pacific; Lonnie Frisbee’s preaching fills Calvary Chapel’s tent — the counterculture’s unlikely awakening, seedbed of contemporary worship music and a generation of evangelical churches.
1982
John Wimber leads the Vineyard: “power evangelism,” healing prayer, and intimacy in worship — carrying the charismatic renewal into the mainstream evangelical world (Frisbee’s Mother’s Day 1980 sermon at Yorba Linda its famous spark).
Today
The center of gravity has moved: most Christians now live in Africa, Asia, and Latin America. The faith that went east from Jerusalem before it went west has become, in fact, what the councils called it in hope — a church of the whole inhabited world.
