The Nicene Age

Who Demophilus of Constantinople was

The Homoian who held the capital's cathedral for the Arian communion's last decade — and who, when the newly baptized Theodosius offered him the choice in 380, creed of Nicaea or the doors, chose the doors: gathering his people, he cited the Gospel ('when they persecute you in one city, flee to another') and led them out to worship beyond the walls. Forty years of Arian Constantinople ended in that procession; he died in the suburban meetings he had chosen over the throne.

Also listed in the bishops of Constantinople and heretics & schismatics.
