I see you are attempting to be dogmatic again. Neither of these two dogmas refute sedevacantism, however. In fact, this one specifically refutes you, since you don't submit yourself to the decrees of the Second Vatican Council as commanded by your "pope".
"[...and I promise true obedience to the Bishop of Rome, successor to St. Peter, Prince of the Apostles, and Vicar of Jesus Christ.] I likewise undoubtedly receive and profess all other things delivered, defined, and declared by the sacred Canons, and general Councils [and particularly by the holy Council of Trent, and by the ecuмenical Council of the Vatican, particularly concerning the primacy of the Roman Pontiff and his infallible teaching. I condemn, reject, and anathematize all things contrary thereto, and all heresies which the Church hath condemned, rejected, and anathematized.]" (Tridentine Creed-Pope Pius IV)
I added parts you conveniently left out from the Creed. Note it says "true" obedience, not "blind" obedience. If you cannot discern what the difference, then you need to look it up and study it till you fully understand and comprehend what "true" obedience vs "blind" obedience is. Sedes are notorious for claiming the the error that the Church demands "blind" obedience to the pope when She demands "true" obedience. Were She to demand "blind" obedience, we would then be bound to blindly submit to the pope.
Note we are to PARTICULARLY
profess the primacy of the pope - and you? What do you do? You profess he's not even pope, in that way you figure you've got the whole issue covered. Very sad.
The Creed specifically calls for us to profess and believe everything in it, not submit to anything. I think if you will spend time to learn the difference between profess and believe the true faith, and blind submission to the pope and his teachings, you will have lose what little reason you have for your sedevacantism.
Notice, it's not just definitions and canons that we must submit to.
There is nothing in the Creed demanding we submit or blindly submit to the pope or his new teachings no matter how often you make that false claim. To even suggest such a thing is not even Catholic. Do you realize that?
Notice the bolded and underlined Stubborn. Sedes agree that the blessed Peter "SHOULD" have perpetual successors. That doesn't mean that blessed Peter 'WILL" have perpetual successors. Sedes also agree that the Roman Pontiff is the successor of blessed Peter.
The lengths sedes will go to in order to save their worthless opinion is truly amazing. The mind twisting word play you sedes practice is phenomenal because yes, it most certainly does mean that per Divine Law, St. Peter should have perpetual successors because Our Lord said so, if it were as you are wont to interpret, then the sedes must agree that blessed Peter SHOULDN'T have perpetual successors because Our Lord did not say "would" have, He said "should" have perpetual successors. Your silly interpretation makes Our Lord question His own Law as it's being decreed, which wholly absurd as it is, does accurately agree with the sede thinking.
Unfortunately, for you, however, the Concilar Popes are NOT to be considered Roman Pontiffs due to their public heresy.
This is nothing more than your worthless opinion, which you elevate above defined dogma is all this is. Do you realize that?
