{{Orthodoxchristianity}}

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]].
