Devil does exist. He is never idle. Man has free will, to take on temptation, or to thwart it off. The devil had much fun with Martin Luther. Conversations with the devil, he had. Luther did not know his catechism enough to thwart the devil. That was Luthers down fall. And for that, the Sacrifice of the Mass was desposed of. No man had need of ordination. Followed by no need of forgiveness of sin. Devil knows us better than we know ourselves.
