"I know there are priests that are heretics. Although I don't know if you understood them correctly in this case. "
Actually, I understood them just fine in this case. They differed in their understanding of transubstantiation. I know what the doctrine is, and I know that there is not universal acceptance of the precise definition, even among RCC priests.
It was an interesting discussion, that one. It went on for about three hours, over some very fine old Port. I enjoyed it enormously, as I have enjoyed many discussions about doctrine in several denominations.
We left it undecided, I have to admit, but all three of us had quite a rosy glow about us when we parted.
I know that there is not universal acceptance of the precise definition, even among RCC priests. Like I said, there are always heretics. And again, even "near-universal" acceptance defeats your ridiculous assertion.
