RR do not refuse subjection to the Pope.
I think you meant sedes.
Sean, do you even logic? SVs refuse subjection to a man they don't believe is the Pope. To claim that they refuse subjection to the Pope is to beg the question that Jorge Bergoglio is the pope. As per the quotations cited, if Jorge is the pope, they would be materially schismatic, but not formally. SVs base their refusal of subjection to Jorge on the well-founded questioning of his legitimacy. Even Bishop Williamson and Avrille have stated that their position is "understandable".
(Non-Chazalist) R&R on the other hand assert that Jorge is certainly and categorically / unequivocally the pope. In which way are you subject to Jorge Bergoglio, aka "Pope Francis"? By saying "He's the Pope." or by putting up a picture of Jorge at the local Trad chapel?
This difference is in line with my analogy about taking the $100 bill. If you see a $100 bill on a table and pick it up, thinking it's yours, but it turns out to belong to someone else, you have committed theft materially but not formally. If you see a $100 bill on the table and pick it up, thinking it belongs to someone else, but it turns out to belong to you (say you left it there earlier but forgot), then you have committed theft formally but not materially. SVs are potentially in material schism (if Jorge is the pope), but not formal schism. R&R on the other hand are in danger of formal schism.
If rejecting a Pope's Magisterium, refusing to accept the Mass he promulgated and to recognized the saints he's canonized, etc. if that isn't refusal of subjection, then there's no such thing. As I said, merely paying lip service, "Yep. He's the Pope." and putting his picture up in the vestibule while rejecting everything the man stands for, that doesn't constitute "subjection" by any reasonable standard. Now, where it gets blurry is that classic R&R holds that in principle you must obey the Pope except when he teaches something erroneous or commands something evil. But when is the last time anyone accepted anything that Jorge taught or commanded? Do you respectfully read through each Encyclical (Recyclical) of his and learn from the Holy Father, while respectfully disagreeing with the particular sentences that you find fault with? No, you simply throw them in the trash bin before even reading them. I called you out on another thread for deriding and mocking Jorge. Is that the proper attitude of a Catholic who believes the man is the Pope? Your attitude should be, "Holy Father, I must respectfully disagee with [this, that, or the other point]." To hold the Holy Father, the Vicar of Christ, in contempt the way your clearly do, that's crossing over into a formally schismatic attitude. Probably the only thing absolving you of formal schism would be the confusion of this crisis.
