Church History Timeline

The history of Christianity runs from the crucifixion, resurrection and Pentecost in Jerusalem around AD 30 to 33, through the Edict of Milan that ended Roman persecution in 313, the Council of Nicaea in 325 and the Council of Chalcedon in 451, the split between East and West in 1054, and the Reformation that began in 1517, to the missionary centuries and today’s global church of about 2.3 billion people. Through all of it runs a single thread. Jesus said, ‘I will build my church,’ and he has.

Key dates in church history at a glance

What are the main periods of church history?

Historians divide the two thousand years in slightly different ways, but most accounts use periods close to these seven:

1. The apostolic age (c. AD 30 to 100): From the resurrection and Pentecost to the death of the last apostle. The New Testament is written and churches are planted from Jerusalem to Rome.
2. The early church under Rome (AD 100 to 313): Bishops, martyrs and apologists hold the faith together through waves of persecution, until the Edict of Milan.
3. The age of the councils (AD 325 to 787): Seven great councils confess who Christ is and settle the creed most Christians still say.
4. The medieval church (c. AD 500 to 1500): Monasteries, missions to northern Europe, the split of East and West in 1054, the universities and the crusades.
5. The Reformation era (c. AD 1500 to 1650): Luther, Calvin and the radical reformers, the Catholic reform at Trent, and Bibles in the languages of the people.
6. The missionary centuries (c. AD 1700 to 1900): Revival in Britain and America, the abolition of the slave trade, and missions to Asia, Africa and the Pacific.
7. The global church today (AD 1900 to today): Pentecostal growth, ecumenism, persecution and revival, and the shift of Christianity's center to the global South.

This is the chronological companion to our thematic guide to Christian history.

Where scholars differ on a date, this page says so.

The full timeline of Christianity, era by era

• c. AD 30 to 33

• c. AD 30 to 33

The thread through it all

Read the whole story and one thing becomes plain: through every century, every council and controversy, every rise and fall of empires, one Person holds it together. The church has been divided, persecuted, corrupted, and renewed, and yet it has never once disappeared, because it was never finally ours to keep. Jesus said he would build it, and he has.
