First, 90% of Catholics and 99% of non-Catholics could give a crap what the Vatican says anyway as they have lost all relevance issuing boring pablum statements for the last 50 years.
The only ones who even pay attention to what the Vatican and Popes say are the Neo-Caths who treat him and the Vatican as a god.
I do not think the official Church takes this as a dogmatic matter because they are at their core opposed to dogma and dogmatic definitions. They want everything to be malleable and subject to reinterpretation. So their aversion to dogma ironically prevents them from defining error. In my opinion this is God guarding the indefectability of the Church. These Popes and Commisions say a lot of meaningless crap, but none of it is dogmatic or being imposed as obligatory.
I have always found Fr. Le Floch's quote prophetic. I believe this Crisis may have been allowed precisely to have the Church, in the future, define the limits to Papal infallibility and right the ship from VCI. After VCI Catholics began to place all trust in the Pope and see him as almost inerrant in all respects because we had such great Popes after VCI and VCI stressed Papal authority. Catholics, buying into this "heresy" as Fr. Le Floch put it, were set up for the Crisis. Look at all of the Pre-VCII Bishops, a vast majority orthodox, who caved in to a lot of the ambiguous VCII docuмents after the Pope expressed his wishes. Look at all of these great orthodox prelates and priests who "obeyed" the Pope and shut their mouths after VCII. This was all a result of the problem Fr. Le Floch speaks of. The Pope had become a King who had absolute power. It was the Devil's preparation for the Crisis. Using an overinflated respect and obedience to the Pope to cause the destruction of Faith. The cure to this crisis, I believe, will be a return to the proper understanding of the Papacy subordinate to the Faith.
Ironically the liberal Popes despise their own authority and never use it, except in disciplinary matters to "keep the peace".
