Fundamentalist Protestants must believe the Catholic Church is "the whore of Babylon" or else become Catholics themselves. Why is this so hard to understand?
Because it is absurd.
It's also absurd to believe that the Jews (in particular the Orthodox "Talmudists") are the "real power" behind Freemasonry, Communism, liberalism, and modern liberal Biblical theories (which Orthodox Judaism utterly rejects), but that doesn't keep people like Metatics, Sungenis, Haigh, Gumaes, Solange Herz, Sobran, and other Catholics from insisting on it. In fact, there was a link to an anti-Jewish Catholic article on "the Jews run Freemasonry" in a recent thread on FR.
I guess what goes around comes around.
Are you blaming all Catholics for what those people do?
