Maybe. Maybe not. How would you determine that?
Would you have opposed St. Paul at the time even though he was proven to be right?
**How was he proven right? By Peter’s confirmation of his being right, the only way to objectively have proved that he was right. **
Our Saints are living. We have St. Paul. And we have the tradition of St. Paul (who didn’t know he was “St” Paul at the time) and it’s handed down to us in the Church. “But if WE or an Angel of light preach a gospel different from the one we have given…” **The popes are guaranteed by promise of Jesus Christ Himself that they cannot lead the Church into error. The popes have not preached a different gospel. **
Why did St. Paul put that “WE” in there? I assume he meant we, since he knew Peter couldn’t lead the Church into error.
And…by saying that “we’d best listen to the Pope” if we don’t understand him and it harms our faith, we’d best listen to the Popes of before because we understand them. The current Popes have to reconcile what they say with what came before. Until they do speak with the understandable voice of Peter, we won’t correctly follow them. And that could be disastrous. Paul VI told us to follow the bishops that didn’t understand the Council. If they did, B16 wouldn’t be talking about the failed implementation of the Council.
**The popes cannot teach to the faithful or present to them anything that is contrary to the truth. I’ve no idea what you mean when you seem to imply that the post conciliar popes have taught contrary to their predecessors. I don’t believe that they have. They may have clarified or further explained, etc. (for example, the difference between “material” and “formal” heresy, but they have not contradicted a one, back to Peter. **
So, until they straighten it all out and heal the rupture of discontinuity and clearly show the continuity. I’ll stick with the tried and true Trent Catechism, Thomas Aquinas, and the clear teaching of the Popes about the Catholic Faith. And I’ll be wary of reading JPII’s “personal reflections” in his encyclicals and I won’t necessarily go along with B16’s book on Jesus if it seems to contradict or affects what I’ve learned from the Magisterial teachings of the Church about our Divine Lord and Savior. Then you’ve followed the path of countless other poor souls, out of the boat, whether formally or no.
