Don’t confuse doctrine with statements and utterances of individuals. The Catholic Credo speaks for itself.
It's a fine Credo. But it takes more than a good slogan to please God. RCs gladly point out every flaw in Luther ignoring the fact he was introduced these views while in their seminaries. Anti-Semitism was prevalent everywhere especially in the Catholic Church at that time. So, that's a non-starter. Luther made the pilgrimage to Rome and was appalled at what he saw. He had seen enough and he had enough to feel compelled to bring these errors to the Churchs attention. God sent Luther and protected Luther else he would have been burned at the stake like so many of Romes "enemies".
