Then they are not Catholics. We believe the Pope is the Vicar of Christ, the Successor of St. Peter who God has chosen to run the Church and guide us to the Truth. If you don't accept this, you are not a Catholic.
most of the catholics i know understand that a pope who is voted in by people has in no way been choosen by god to do anything. Additionaly, most catholics i know believe that the pope is just a man, and a man who has no special contact with god, only a special pointy hat and title.
