Timeline of Church History

The History of the Church is a vital part of the Orthodox Christian faith. Orthodox Christians are defined significantly by their continuity with all those who have gone before, those who first received and preached the truth of Jesus Christ to the world, those who helped to formulate the expression and worship of our faith, and those who continue to move forward in the unchanging yet ever-dynamic Holy Tradition of the Orthodox Church.

Notes

• Some of these dates are necessarily a bit vague, as records for some periods are particularly difficult to piece together accurately.
• The division of Church History into separate eras as done here will always be to some extent arbitrary, though it was attempted to group periods according to major watershed events.
• This timeline is necessarily biased toward the history of the Orthodox Church, though a number of non-Orthodox or purely political events are mentioned for their importance in history related to Orthodoxy or for reference.
