“But if you want examples,”
It’s pretty disturbing for you to compare Augustine, Theodoret and Pope Gelasius to well known heretics. You also still failed to demonstrate how just those three examples were actually in rebellion to the teachings of the Magisterium they were heading, even though I asked you to. I’m guessing you can’t.
All dipped into heresy, and all were called on it. Do you wish me to post the relevant Church documentation? I will not dispute Augustinian heresies since they are (or should be) well known. At least to any Christian.
