Even if a pope is only teaching as a private theologian, he cannot be a heretic. If he is a manifest heretic, he is not a member of the Catholic Church and therefore he is not the pope, period.
It's getting comical now. It's a game. How bad can it get before you finally realize he isn't Catholic? Does he have to sacrifice a child on live television? What does it take?
I think a lot of people think he is a heretic, but that he has to be judged so by the Church. Not that it will ever happen, but there has to be a process. Either God will never allow a Pope to be a heretic, or if it happens, something has to be done about it by the Church. If you think he is not the pope, then PRODUCE A POPE. Elect one, or recognize one of the dozen or so who have been elected by other sedes, and no matter what course has been decided on, get off your high horse.
The Church is supposed to be a monarchy with a distinct hierarchy. The sedes have none of that. They have an invisible Church with a few dozen priests, independent, scattered, with no hierarchy, like protestantism. Support Pope Michael.
