How their histories relate
Schism · 451 and afterA gradual processWider family
The Council of Chalcedon and its aftermath
A breach of communion between churches. The Atlas never treats a schism as the founding of either side, and many developed gradually.
Chalcedon defined Christ as one person 'in two natures'. Most of the Egyptian church, and the churches of Armenia and much of Syria, rejected the definition as a departure from the teaching of Cyril of Alexandria; an Armenian synod rejected its Christology in 506.Read in Coptic Orthodox Church history5 sources
