Why even bother with Theologians when Pope Boniface VIII infallibly declared the necessity of being subject to the Supreme Pontiff:
Or even Vatican I (infallible):
If Bergoglio is the "Pope", ante up and submit to the dogmas of the Church. Otherwise, continue to be a schismatic.
Notice that the dogma says in order to attain salvation, it is necessary to be
subject to the pope, the dogma does not say nor even imply that it is necessary to blindly
submit to the pope even in his errors and heresies.
You must convince yourself that this dogmatic teaching of the Church is precise, it's not mistaken, it's not evil, nor is it complicated to be subject to even heretical popes. It works like this - we have to obey him as the pope in all those religious matters which fall within the ambit of his authority, unless he should command something which is sinful.
That is dogma, that is what Catholics do especially in this day and age.
What Catholics do not do, is we do not expel popes from the Church as if that is our religious obligation - not even in this day and age.
