I believe in the Gospels and Tradition.  My problem lies with those that want to reinterpret scripture to fit their own preferences.   Fr James Martin recently stated he believed it was possible that Jesus, while dying on the Cross, was not certain that the apostles would continue his ministry following his death.   Pope Francis has claimed that the miracle of the Loaves and fishes was actually just people sharing. Cardinals are know claiming that Jesus did not actually state a remarried person commits adultery, because we don't have an actual recording of what Jesus actually said.  Everything is up for reinterpretation.  That my friend is Protestantism, which I clearly am against.
