Most interesting aspect of it to me..... St. Malachy's prophesy.....

Not that I buy into it, but from what I gather, it's kind of like the Joseph Smith/US Government prophecies where the churches don't really endorse the specific prophecies and the origins aren't completely clear, yet a whole significant portion of people within those religions do believe it and the leadership is still well aware of it and
maybe even believe it individually too. The Mayan 2012 stuff was basically a big joke to everyone , but if a new Pope was named that could be connected to Petrus Romanus....and world events start to get dicey.... It would be interesting to see if that prophecy would suddenly start gaining more adherents within the Catholic Church.
