Where they differ
- Chalcedon and its language. The Orthodox speak of Christ 'in two natures'; the Copts of 'one incarnate nature of God the Word'. The 1990 statement treats these as different expressions of one faith; each church must still decide how to lift the old anathemas.

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

Formal dialogue · 1985–1993Wider family
Orthodox–Oriental Orthodox theological dialogue
Official theological conversation between churches. Agreed statements are recommendations until each church receives them.
Official commission meetings from 1985 produced agreed statements at Anba Bishoy (1989) and Chambésy (1990) and proposals for lifting the anathemas (1993).Read in Eastern Orthodox Church history

Still open: The commission recommended that the anathemas 'should be lifted by the Churches', each deciding how. Commission agreement is not the same as acceptance by every church.
