there has always been a movement outside the mainstream catholic church from the donatists, paulicians & waldensens to name a few. the movement exploded with luther, but he was not the origin.

The single comment drew me to watch this video. Well, what is all the huff about. Bishop Barron didn't endorse anything Luther said as being correct. Am I compelled to read Luther. Probably not! Too many great Catholic authors. I'll stick with them.

You might be a bishop, but I am sorry, what you say in this video on Martin Luther sounds idiotic. Martin Luther ripped apart the Church. He started a movement that is still culminating today in modernism and anti-Catholic seculiarism. Because of Martin Luther, many people if not millions have gone to hell. He is not a person to praise. He might be a good writter, but I bet if we gave the devil pen and paper he could write something to tickle your ears too. I really don't understand where you get your theology, its not from the Church.
