Sister Lucia revealed that the Secret of Fatimae is contained in chapters 8-13 of the Apocalypse.
Look at what philosopher and theologian Enrico Maria Radaelli [edited to correct the name] is saying about the papal resignation:
“Not considering these facts is in my view a murderous blow to dogma. Resigning means losing the universal name of Peter and going back to the private being of Simon, but this cannot be, because the name of Peter, of Cephas, of Rock, is given on a divine plane to a man who, in receiving it, no longer makes only himself, but ‘makes Church.’ Without counting the fact that since the self-removed pope cannot in reality resign, the incoming pope, despite himself, will be nothing but an antipope. And reigning will be he, the antipope, not the true pope.”
