The quote from St Aquinas should be the end of every debate about invincible ignorance. The Latin church since 1900 or so has been essentially thomist in its philosophy and yet we see a complete disregard for his teachings of the salvation of 'wild beasts'. The sspx and sedevacantist seminaries primary source of its teachings is St Aquinas and they have seemed to skip over this page. Theological discussion of Baptism of Desire for catechumens is fine,but the fact that the so called "remnant" believes utter disgusting crap-like that a Jєω who rejects Christ as he dies (cmri,sanborn) is mind boggling!
The "remnant" is not the traditional Catholic movement, it is the actual Catholics within it, who are scarce. Just as the fewness of the saved was taught at times when the church was at its height! Very few people were saved that actually had the true faith thrown in their face.
Just look what the people in traditional catholic churches do. Gross immodesty, television and video games, immoral professions, a complete lack of history and knowledge of church teachings.
Just as 80% of traditional Catholics heretically believe that non Catholics can be saved, 80% are immodest from top down. I am not sure what percentage people are watching modern television and video games, but from things I have seen and heard first hand, it is quite a lot. And many traditional Catholics I know are involved with immoral professions.
But But Piux IX taught it infallibly! -- wrong and wrong.
The thing about these so called traditionalists is that they can't be wrong or else everything the traditional Catholics have built over the last 50 years has been in vain, but it has been.
Is the church being restored? No not at all, more heretical teachings come every day from the hierarchy. Is the traditional catholic movement growing? Well the indult is, and the sspx grows a bit every year but the old independent priests are almost all gone, and the sedevacantist groups are stagnant. Only a few new sedes are ordained throughout the entire world in a given year, some years none. The liberal sspx ordains around 20-30 a year. The indult maybe 50+, the resistance 0-2 a year.
Why is that? Because the vast majority and every leader of every group does not believe in the necessity of the catholic church for salvation. How did the apostles and the early saints convert entire cities or countries? Because they believed it was convert or everlasting hell fire.
