The division over Chalcedon

Doctrinal · 451 — unsettled · ecumenical

The council that settled one question opened another that has not closed. The churches of Egypt, Syria and Armenia did not receive the Definition, holding Cyril's formula of one incarnate nature and denying — at length, and from the beginning — the confusion Chalcedon condemned.

How it ended. Unsettled inside this dataset's window. The Alexandrian succession divides from 451 and the Antiochene from 544, and both lines are carried here as their own.

How it ran

451 — Council of Chalcedon (where it began). Defines in two natures; the churches that refuse it divide from this year.

Two natures in one person what was at issue

Severus of Antioch a principal
