This is the classic reponse. This is the "Resistance" line. This is vintage Williamsonism. We wait interminably until another future pope, or some kind of specially appointed conclave, or whatever, makes the call. Meanwhile, we poor saps in the Catholic laity, (and priesthood) simply tolerate the enormities of the reigning pope. We either like it or lump it.
I think it's all baloney. We know exactly what and who these "popes" are. They've behaved intolerably in our faces for almost fifty years. I, for one, have had enough. Let the sedevacantist banners fly. I'm not waiting for a phony church to declare anything about anything.
