Maybe the r&r is more like the Eastern Orthodox position? The pope doesn’t have the primacy, he has the semi-primacy where we obey him only when he is conforming to what we think is Catholic. And when he doesn’t conform we only recognize him. But if Bergoglio isn’t the pope then r&r is merely confused about Catholic theology and they have no obligation to obey a non-Catholic heretic. So it completely depends on whether or not Bergoglio is objectively the pope.
Actually, "r&r" is the Catholic position. We accept that the pope has the primacy per Pope Pius X, who said that upon his election, "he is instantly the true pope and he acquires and can exercise full and absolute jurisdiction over the whole world."
R&R are loyal to this Catholic truth as decreed by St. Pius X. R&R continue 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. Never forget:
"First we are under obedience to God, only then under obedience to man."This is Catholic.
What is not Catholic is to believe that we cannot know what sin is, or right from wrong, or Catholic from not Catholic without a saint sitting on the throne of St. Peter. If that's EO or not I do not know, but whatever it is, it's certainly not Catholic.
