By the way, it is a Catholic DOGMA that no one is in his way of salvation unless submitted to the Roman Pontiff.
You do know that submission to the Roman Pontiff comes at baptism right? And that the submission applies whether there is currently a head living atm. For if what you are saying is true, no baptized babies can enter heaven because they can't submit to a Pope... Since there is not one at the moment, because of heresy or in most historical cases death of a Pope.
If you must "intellectually" submit to the Roman Pontiff it is impossible for babies who do not possess reason to submit to the Roman Pontiff, IF what you are suggesting is true. Rather, theologians have taken care of this "apparent problem" and we must remember that a lot of this applies to even protestant validly baptized babies. They too are in subjection to the Roman Pontiff until whenever the time comes that they submit to heresy, on their own accord. For they are not responsible for the heresies of their parents, as is obvious that no one is responsible for anything other then their own sins/belief/unbelief. This is why it might be possible for a Protestant who has never become a heretic, who might be 9 years old and of course never sullied their soul with a mortal sin. Now the main problem is that most protestants are so wicked that they do not even baptize until much later, so that this is why we can pretty much exclude even the remote possibility of them being saved because without baptism you cannot belong to the Mystical Body of Christ.
Consistently you show that you do not know what you are talking about, instead of humbly admitting you have been wrong. No, instead you make worse arguments then the previous ones.
You did not ever say that you abused St. Robert Bellarmine, people like you that are bad willed don't ever recognize that they can possibly be wrong. If I am proven wrong, I will more then gladly retract anything I have said, if it can be shown to contradict the teaching of the Church.
You must demonstrate that somehow what you seem to be quoting applies to any Sedevacantist that clearly shows no spirit of schism as Most Holy Family and other radical type of schismatics (home aloners, or papal deposers up to 100-1000 years). Now these men are Papal deposer's, because NO ONE previous to their own genius proof texting Sola Denzingerite studies concluded even remotely any of their conclusions. Some of the greatest Saints gave testimony of the other Popes, and men of such great wisdom + learning also never doubted the Orthodoxy of any previous Vatican II claimants.
As opposed to what we are doing is recognizing a manifest public fact that has happened... The fact you keep mentioning, that any of the laity have deposed a "Pope" just shows how completely ignorant you are of the arguments for/against the heretical pope thesis. Not even Cajetan, Suarez, or John of St. Thomas argue like how you are. All of them recognize that a Pope who would theoretically be deposed by the Church, would only do such a thing after the fact that Christ had already done such a thing in the first place... Which is what we have said, all this time. So, not even one theologian disputes this particular point... Yet, you somehow dishonestly KEEP making the claim that is somehow possible for even the Church to do such a thing! This is the heresy of Conciliarism, and all the previous theologians understood this heresy very well which is why it was so difficult for them to come up with a way of how to properly "depose" a heretical Pope.
At the end of the day, the disagreement even among the said theologians is not as much as most people think. The disagreement is between fine distinctions, nothing of the sort of the modern SSPX vs SV debate. Not even close, the chasm between both theological systems is not just a few distinctions, it is quite something different. Each day it grows even wider, because in their defense of heresy they become even more anti-Catholic in their view. Whereas before it was possible to say that something was not controversial, now it is becoming extremely controversial.
The line is being drawn in the sand between the disciples of the Lord, and false teachers. My hope is that all traditional Catholics, can be able to modify their Sedeplenism at least in such a way as not to embrace heresy in the process.
