His predictions have only been used after the fact to fit a prophesy, they are so vague that you can make them fit anything. Although I'm not a practicing Catholic anymore, I think he's a great pope but if he sees a reason to abdicate then that's also fine with me. Think one of the last ones did because of health reasons but not sure, don't really keep up with the popes.
While I was looking this up, I noticed that the KKK is anti catholic, something I didn't know before. Kind of makes sense.
