Is that the crux of the issue with you Sedes? You think one cannot disagree with the pope?
You think that if you DON'T DENY the Pope's office, then you must blindly follow everything he does, both good and bad? Things he is allowed to do as pope, as well as things not lawful?
You realize, of course, that a Pope could theoretically step outside his authority, by commanding you to do something damaging to your faith, for example. That would be a command without authority.
I know some of you would say, "How could a POPE be damaging to your Faith?" and I don't have the answer. This Crisis was not of my choosing -- it has come to us by God's permission.
The strange thing is, once the Sedes deny the pope, they are left just as clueless as the non-Sedes -- regarding "how does this mess get cleaned up", "what do we do", "how did this happen" -- which is why there are countless answers for each of those questions in the Sedevacantist as well as the non-Sedevacantist world.
