This is when the paganism of human nature began to form nicolaitan churches on a grand scale. Constantine’s ‘church’ is simply the most grotesque example. Its all in the Bible, where Yehova condemned it. ( for catholics, that means “Biblical.”)
Jesus promised to remain with His Church until the end of time, preserving it from error. So your position is that His promise fizzled out at the beginning of the Second Century. So your position is that Jesus was a liar.
He promised his “assembly” that had been his from the beginning, not a church.
He has been with us all the way, but Constantine’s pagan ‘church’ is not part of us; it is a source of antagonism to his assembly.
It is Yeshua’s words that affirm this.
You can tell us what your position is; you haven’t a clue as to mine.
