Just a brief observation regarding CNN and their episodes on the Papacy. Two blatant errors. First Avignon was not in France at the time. That was a key issue then and someone should have fact checked it. There is this thing called the Internet and they have this thing called Wikipedia... You get my point.
Second, some alleged theologian said that Luther was the only person to have opposed the Pope and survive. Duh! Ever heard of Ockham, Marsilius of Padua, and a few dozen others! They were two hundred years earlier!
Overall in my opinion, being somewhat aware of the papacy in the seventh and 14th centuries, CNN managed to create a story which is a prime example of fake news, if not just sloppy.
Next time try and get some people who know something folks!
