I have another question for you Sweden, in addition to the John XXIII question.
If a pope does not lose office for teaching heresy in his fallible capacity, then do you not give lip service only to the dogma that heretics are outside the Church? Or do you assert that a heretic who is outside the Church can still be pope, so long as he doesn't try to bind all the faithful and invoke infallibility for his heresy?
Finally, if what you say is true, then how many heresies can a pope teach in his fallible capacity? Can he teach one and still be pope? Seven? Seventy times seven?
