“Pope Francis to Hold Mass for Armenian Genocide Centennial”
Now this is fascinating. Gregory of Narek, as far as I am to tell, was a monk of the Armenian Apostolic Church which also venerates him as a saint. Said church is part of the non-Chalcedonian communion (Oriental Orthodox) and has not been in communion with either Rome or Constantinople since they definitively rejected the Chalcedonian dyophysite formula in AD 554.
All of which makes me wonder exactly how is it that Rome is declaring a presumably non-Chalcedonian monk to be a Doctor of the Church?
