Ever hear of Nestorianism? The Antiochenes were anathematized by the Council of Ephesus for dividing Jesus into two persons.
Check your history.
Now why would I or any other Christian worry about what one of your religious councils determined???
No doubt in my mind that the Nestorians deemed your religion as heretical...They refused to bow down to your pope and that puts them to the top of the scale in my book...
