VII is a sect, a new Church that has nothing to do with the Chatolic Church; THEN
SSPX was founded because of this: to give us Priests (valid ones) and secure the Catholic Faith because the Catholic Faith is no longer being professed in Rome.
The history can teach us:
Now with Dom Fellay saying: "VII is more good than bad" and many traditionalists considering a deal with Rome as long as they have their Latin Mass (in fact Francis is probably going to make a deal with SSPX, which means SSPX will no longer hold the Catholic Faith).
The Pope is not the issue.
We have a constant here:
Since John XXIII every year Rome is destroying 2000 years of Catholic teaching. Could St Peter have desired to destroy the Church that God gave him the keys?
VII has teach that there's no true religion, all religions are equal and all religions are good. Every Pope since VII have entered into this error and the next one will enter as well. It's impossible to think a Pope can be Catholic while praying with Jєωs, muslims, denying Jesus as the only and true God, mocking Jesus Christ on the Cross.
We had very bad moral Popes in the past. BUT when speaking from the Chair of St. Peter not a single Pope has taught error. That's why despite all the wars and bad times we have the true doctrine today; intact and pure. God never allowed and will never allow errors to be teach in from the Chair of St. Peter.
VII is the French Revolution: It's a new religion and I can't call the head of this new religion a Pope.
There's no way back: the Sede is Vacante since VII.
