At least you made a response. Note that "a RC is not presuming what Rome presumes of her popes, that of possessing a charism of personal infallibility," was sppsd to say "a Prot is not presuming what Rome presumes..."
For that "without a pope, everyone is a pope" is repeated Roman rhetoric which is manifestly contrary to what Rome defines a pope to be, while RCs decide on who to believe and what they mean.
Amen
What Catholics fail to realize is that they are doing what they condemn everyone else who doesn't submit to Rome of doing.
They are, all on their own, using their own personal interpretation, deciding who or what is correct and incorrect.
If they decide that Catholicism is correct, it's because they have read and chosen to believe that Catholicism is correct, using their own personal interpretation of what they've heard.
