Non-Chalcedonian Christianity

[1] Non-Chalcedonian denominations reject the Christological Definition of Chalcedon (which asserted Dyophysitism), for varying reasons.

Today, the Oriental Orthodox Churches predominantly comprise most of non-Chalcedonian Christianity.

The Christology of the Church of the East (i.e., "Nestorian" Christianity) may be called "non-Ephesine" for not accepting the Council of Ephesus, but did finally gather to ratify the Council of Chalcedon at the Synod of Mar Aba I in 544.

The end result was the existence of two distinct patriarchates of Alexandria and Antioch for almost 1500 years, continuing in the present time.

In India and to a lesser degree in Persia, the schism that occurred was between the Oriental Orthodox and the Assyrian Church of the East.
