That's a new spin on things!
“Undisputed” is the key word. As has been explained to you countless times, a pope may certainly have an incorrect opinion. True infallible pronouncements are very rare. However, Pope John Paul II’s prohibition against supporting abortion rights was certainly intended to be infallible: he invoked a historical and global consensus among the faithful bishops. But that’s probably the only one I can think of SINCE the assumption of Mary.
Not if you look at what Vatican I said about the subject. The ultramontane position may be the usual understanding, but the fact is that no pope can act on his own without a “party” behind him. John Paul and Benedict did somethings that greatly dismayed the “liberal” party in the Church, but they knew they had wide support in what they said. Pope Paul was called Hamlet because in the end, although he had upset the applecart, he found the results of his own actions quite disturbing, especially the tendency of many churchmen to carry things far beyond what he hoped would happen. That’s the problem with revolutions. Francis is seeking the same kind of popularity that made John Paul so “hard to handle.” So far he has got it; his arbitrary actions during the synod were his first stumble , and John Paul, who had had to deal with the Communists, was much more adroit.
