The Assyrian Church of the East claims continuity with the historical Church of the East, and it is not in communion with either the Oriental Orthodox Churches or the Eastern Orthodox Church. The faction of the Assyrian Church that became in full communion with the Holy See of Rome is the Chaldean Catholic Church. After the Common Christological Declaration in 1994 between the Assyrian Church and the Catholic Church, and a 2001 theological dialogue between the churches, they drew up guidelines for faithful to have mutual admission to the eucharist between the Chaldean Catholic Church and the Assyrian Church of the East.
