For me, the driving theological principle is that it's not possible that the Magisterium, the Mass, the Universal Discipline (Canon Law), and the cult of saints (with their pantheon of bogus saints, despite most theologians holding canonizations to be infallible) can be corrupted.
Yes, I agree. I'm just saying it's much bigger than that. Hypothetically, if every *real* Catholic in the world (probably about 30% of all catholics) agreed that V2 was a sham and that all V2 popes were fake, that only solves the problems in the Church
theoretically. Practically speaking, God has still allowed the Church to be infiltrated with up to 50% of all the clergy who are freemasons intent on destroying Her (with the rest of the 50% of the clergy not sure how to solve the problems because they don't control the leadership positions), and the practical issues of the new mass, new sacraments, new catechisms, etc still remain.
In other words, even if most of a country realizes that their govt is illegitimate communists, the practical problems of a bad govt remain.
