Two problems I can see with your statement:

1. The same argument can be applied by the Jewish religion against ALL christianity.

2. A revolt does not mean that the original party was correct. Far from it. Listen very carefully to this so you understand it. The Church they revolted against is the SAME Catholic Church that once killed and persecuted people for saying the Earth was round, when the bible clearly showed it was flat. And drowned/burnt women at the stake because they were witches (God would save them if they weren't). Who killed women for sleeping with men out of wedlock because they were succubus (or something - devil incarnate).

Is it possible that some of their doctrine, and interpretations of the bible, were innacurate? (It's a pretty big thing to kill people for disagreeing with you in spite of the bible saying THOU SHALT NOT KILL)
Accepting that, why can't some of the revolters have it MORE correct than the original Catholic Church?
