Nestorian schism
### Nestorian schism

The Nestorian Church, known as the [Church of the East](/wiki/Church_of_the_East "Church of the East") within the Syrian tradition, rejected the decision of the Council of Ephesus and its confirmation at the [Council of Chalcedon](/wiki/Council_of_Chalcedon "Council of Chalcedon") in 451\. This was the church of the [Sasanian Empire](/wiki/Sasanian_Empire "Sasanian Empire") during the late 5th and early 6th centuries. The schism ended in 544, when patriarch [Aba I](/wiki/Aba_I "Aba I") ratified the decision of Chalcedon. After this, there was no longer technically any "Nestorian Church", i.e. a church following the doctrine of [Nestorianism](/wiki/Nestorianism "Nestorianism"), although legends persisted that still further to the east such a church was still in existence (associated in particular with the figure of [Prester John](/wiki/Prester_John "Prester John")), and the label of "Nestorian" continued to be applied even though it was technically no longer correct. Modern research suggests that also the [Church of the East in China](/wiki/Church_of_the_East_in_China "Church of the East in China") did not teach a doctrine of two distinct natures of Christ."


Were there any notable conversions or debates within the Nestorian Church?
