You’re just using the word “communion” to your own benefit. History has examples where there were 3 popes and saints on all sides. God does not require us to mind-read or be experts in theology to save our souls. IT IS SUFFICIENT FOR CATHOLICS TO HOLD AND PRACTICE THE TRUE RITES TO BE SAVED. It is not a requirement to have the perfect opinion on the papal status. History proves this.

You say that as if I didn't agree with you.
I do not expect all Catholics to know about subtle theological points. To do so would be both injust and against reason.
You need not worry about whether God would send people to hell because they don't get a subtle theological point. He won't. God's Justice isn't some idiotic algorithm who'll assign people to heaven or hell arbitrarily.
On the other hand, on this forum we are debating theology. If you do not want to take a position, it is perfectly fine and God will not send you to hell for that reason.
On the other hand I studied the question and I do take a position on the subject. Your refusal to answer the substance of my arguments is faulty.
I am not making an argument trying to see who goes to heaven or to hell. I am trying to better understand and to help others understand better the current situation we are in.
Those who prefer to stay ignorant , stop wasting my time.
