Yes, we do. If you set yourself in the place of Christ, you are an antichrist.
The more I think about this article, the funnier this article gets. The argument goes Martin Luther should have know his place and shouldn't have questioned/criticized the pope. The author of this article criticizes the pope. The author says to come join the one true faith, led by a pope who doesn't share the one true faith. Seriously, consider using a mirror.
So why are you bitching that, "Catholics have much more in common with orthodox Lutherans."
