Our souls are saved by adhering to the Catholic faith.
So, where does the Pope come in on all of this? Post Vatican II, why, what the pope says IS Catholicism and this is a mentality that is not to be found in any devotional book of the past. None of the Traditional Catholic prayers say this. If it was really important to follow the pope no matter what, wouldn't one of the great saints or even one of the great popes of the past mention this?
The post-concilliar "catholics" think that the pope can even change the very words of Our Lord and Savior.
Now, it's okay for the sedevacantists and the SSPX to thrash it out amongst themselves because this will help the person seeking the truth to analyze what is put before him.
