Let Jesus settle it. He advised us to beware of false prophets, those who looked like sheep, but were really wolves. He said by their fruits we would know them. A good tree bears good fruit, a bad tree produces rotten fruit. What have been the fruits of the recent papacies? Try looking at the horror more objectively--we have a pope who organizes prayer festivals to false gods. How can such a man lead his Church through the current crises?
And here is St. Paul himself showing us how to discern the true from the false as well. "If we, or an angel come down from Heaven, should preach to you a gospel other than the one I have preached, let him be anathema." In other words, we must hold onto what has always been taught, not chase after new doctrines.
JPII preaches a new humanist gospel, novelties never ever preached before by any pontiff--that Jews need not be converted, that they have no need of Jesus as their redeemer, that all religions are somehow good, that all men are somehow saved. Such doctrines were never taught before in the Catholic Church. And even if he does not himself teach these novelties in so many words--he teaches them by praxis, or by remaining silent in the face of myriad novel pronouncements on his behalf.
These are indeed weighty allegations. Of course, I can list texts of JP II denying all of those - so where are the ones of him affirming them? The first three are contrary to Dominus Iesus.
COMMISSION FOR RELIGIOUS RELATIONS WITH THE JEWSJesus affirms (ibid. 10:16) that "there shall be one flock and one shepherd". Church and Judaism cannot then be seen as two parallel ways of salvation and the Church must witness to Christ as the Redeemer for all, "while maintaining the strictest respect for religious liberty in line with the teaching of the Second Vatican Council (Declaration Dignitatis Humanae)" (Guidelines and Suggestions, I).
