so Campion, are you in favor of a one world religion with the pope at the head?
I would hope that all Catholics are "in favor of a one world religion with the Pope at the head," if by "one world religion" you mean one faith, one baptism, one God and Savior for the entire world. That's what "Catholic" means.
If you mean some syncretistic combination of all religions, that would be infinitely wicked. No Pope who tried to head something like that would even be the Pope, because he would not be a Catholic.
