Fr Chazal's position could hold water, but then it's just an R&R thing anyway. I'd say yes to it, but to say the pope is pope, but not really pope, is not Catholic teaching. Who cares anyway? We've always been subject to heretical authorities. The people can request removal of a heretic bishop, perhaps even the pope, but then, the pope is specifically not subject to deposition, especially when a huge majority accept him as pope. The one thing I know is that no group or person has a satisfactorily complete handle on any of this. I tend to think the pope is the pope and I think he will be punished for all he's done, to include being declared an anti pope for his heresy. Just not by the laity. We don't have to accept sin as Bergoglio permits or promotes, but must resist his attempts to dismantle the faith where and when we can, since he's still the pope (imho). We have to combat his garbage with charity while avoiding divisive rhetoric and dogmatic propositions about his state within the church because it isn't going to make him go away. The best way to combat a guy like him is through prayer and sacrifice unless your position demands more. The one thing I can't stand is when people demand you believe what they believe or they try to excommunicate you.
