Luther claimed as the indictment at Worms says to be wrong and what the church had said for fifteen hundreds years was wrong. He believed he was right in saying this because of his own studies of the Scripture and on must assume that he was directly inspired by the Holy Spirit to read it all correctly. You make the same claim, and argument for or against such a thing is really futile.
I dont follow any of those guys. Protestants you know are simply daughters of the RCC. They retained many of her errors too. Catholics really need to stop preaching another gospel and like God said in Revelation to those in the RCC religion, Come out of her, my people, that ye be not partakers of her sins, and that ye receive not of her plagues.
