I think the recognize and resist folks have to answer how they are not in schism. They claim that they are subjects of the authority of a schismatic and heretical man, but they refuse to obey him whom they believe to be the legitimate reigning pontiff. Either way you look at it, they are on a trajectory to ruin. They need to understand that heretics and schismatics are outside the Church and can never have any authority whatsoever and to follow/recognize one is to join him in heresy and schism. And they need to understand the necessity of obeying the man whom they recognize as the sovereign pontiff.
I'm embarrassed for any Sedevacantist that actually uses that argument. It's pathetic.
You are just plain WRONG, in particular the part I bolded.
The Pope doesn't have the authority to change the Faith or destroy the Church. It's basic "Traditional Catholicism 101" -- part of the charter of Traditional Catholicism (or, the foundation/justification for the very existence of the Traditional movement). We Catholics have a right to resist the Pope on such things. Haven't you ever heard the argument?
If a parent tells you to commit a sin, you can disobey that parent, because he's stepping outside his authority? You don't have to declare that he's not your father.
Like Bishop Williamson said -- Sedevacantists and Novus Ordo Catholics both err on the subject of Papal Infallibility/obedience -- it's just that they each deal with that "fact" a different way.
Sedes believe that the Pope must be obeyed in everything, so they reject his papacy.
Novus Ordo Catholics believe that the Pope must be obeyed in everything, so they follow him off a cliff.
They both need to hit the books.
P.S. Do you think Our Lord was kidding when he said "even the elect" could be deceived? Meditate on that for a bit. Who do you picture, when you picture "the Elect" falling? When He says "the Elect", He's talking about SERIOUS CATHOLICS -- like the people on CathInfo. That means that even WE could be deceived into taking the wrong path.
