Coptic Orthodox Church

Principal Christian church in Egypt. Until the 19th century it was called simply the Egyptian Church. It agrees doctrinally with Eastern Orthodoxy except that it holds that Jesus has a purely divine nature and never became human, a belief the Council of Chalcedon rejected (see Monophysite heresy) in AD 451. After the Arab conquest (7th century), service books were written with Coptic and Arabic in parallel texts. Church government is democratic, and the patriarch, who resides in Cairo, is elected. There are congregations outside Egypt, especially in Australia and the U.S., and the church is in communion with the Ethiopian, Armenian, and Syrian Jacobite churches.
