You are assuming I believe Constantine was a light switch, the pre-Constantine church one thing, the post-Constantine church suddenly something altogether other. I do not see it like that. I see the pre-Constantine church morphing into the Constantine one, the Papacy years later putting the finishing touches to the “morphing” process.

Then when did the great apostasy actually occur? At what date did the beliefs and teachings of the early church become unreliable?

>You are looking for light switches again. No particular date we could call a light switch, but we know by the time of John’s epistles, including Revelation, it was bad enough that John would say -

“Even now are there many antichrists...they went out from us, but they were not of us; for if they had been of us, they would no doubt have continued with us: but they went out, that they might be made manifest that they were not all of us,” 1 John 2:18, 19.

The seven churches in Revelation has many references of apostatizing going on at John’s day, for example, the Nicolaitans. Christ warning the churches to hold fast amidst it.
