The Beginning of the End We Now Behold

61 years after the Church became a part of the Empire:

“And what is our condition? Love is grown cold; the teaching of the fathers is being laid waste; everywhere is shipwreck of the Faith. The mouths of the faithful are silent; the people driven from the houses of prayer, lift up their hands in the open air to their Lord which is in heaven. Our afflictions are heavy, martyrdom is nowhere to be seen, because those who evilly entreat us are called by the same name as ourselves.”

Basil to Ascholius, 374 AD

The barbarians and the faithful are called the same thing, Christian.
