It appears that a chess puzzle composed by Pope John Paul II is a hoax. The list of religous leaders who played chess can be found in one of the articles here under religion and chess. Also, a list of other famous players who play chess can be found here:

I have come across a couple of chess puzzles composed by the late Pope John Paul II in various books and articles. One that I especially enjoy features an underpromotion of a pawn to a knight. I have a few questions for the chess.com community:
1. Have puzzles, studies, and/or games involving pontiffs and/or other clerics ever been compiled in some form (e.g., books, extended articles, websites, etc.)?
2. If no dedicated compilations exist, what sources are there for "chess personalities" that are not famous masters? In other words, if I want to search on my own for puzzles, studies, and/or games involving pontiffs, how might I get started?
3. Besides Pope John Paul II, are there any other pontiffs that I should add to my list of chess enthusiasts? Are there other clerics besides Ruy Lopez and William Lombardy? Are there "chess-enthusiast" clerics from other religions?
