I think Catholics tend to be amillennial, IIRC.
They would believe that the world ends with a big bang after things get real bad.
I imagine the prophecies about the various Popes might have something to do with Catholic response. I remember when the cardinals were meeting after JPII died that there were a number of articles about "someone's" prophecy that there were only 2 or 3 more Popes left. I wish I could remember more about it.
That would be the prophecies of Saint Malachy.

I wish McLaughlin & Associates had gone out and polled the Islamic Jihadists and asked how many of them believe the stuff I have on my FR homepage.
Thanks for the links, DJ. I thought I was remembering something real, and not (again) something just banging around in my skull. :>)
