I am not Catholic...so this story stuck with me always. I read that centuries ago a mystic monk was given a revelation. He wrote down the names of every pope until Armageddon. The paper was lost or locked away and found again in the early 20 the Century. All of the names to that date were correct. Whomever had it held on to it to see what happened in his lifetime.
Again,the names (and they are allowed to choose whatever name they like) came to pass. It has gotten locked up in a vault somewhere,but there were only supposed to be three more popes after John Paul II.

JPII served a good long time...I was hoping for the same for Frederick or whatever his name was,but he gave us..two or three years...now we have Mr. Let’s Change The Lords Prayer..

The story was in an actual publication,likely a newspaper. Pre-internet and I never bought tabloids. It was presented as an interesting blurb kind of thing....rather like “Store Clerk Correctly Predicts Every Presidential Race Since Eisenhower!” stories.

So,it doesn’t quite fit with this Pope is the Last Pope..but close enough. Even Mystic Monks are probably not 100%... CHILLS.
