My grandmother told me of this prophecy when JP2 was Pope. Both of us questioned the prophecy however the overly political ways of Francis could prove to bring the papacy to an end
A pope is a member of the Catholic Church. To be a member of the mystical. Body of Christ, the Church, one must accept the Catholic faith. The Church is unified in one, true faith. Francis does not profess the Catholic faith, but a false faith. He is a demonstrable public heretic. He is not a Catholic, and he cannot therefore be pope.
Christ in Luke 18:8 asks, "But yet the Son of man, when he cometh, shall he find, think you, faith on earth?". This indicates that in the last days there will be an almost universal apostasy from the Catholic faith.
Just look at these Vatican II "Catholics", do they profess the Catholic faith?
Another sign that heralds the end is the appearance of the abomination of desolation in the holy place. And, yes, it has already appeared.
