I think the Cardinals will be looking for someone with a much shorter reign this time, to follow the nearly 30 year papacy of JPII.
I do think Arinze is a good possibility, but I think he may follow the next pope. I think Arinze is or will try to bridge the gap with Islam and imho this will be the beginning of the end.
Well, as mentioned in another post, I heard that there is a prophecy "master" list that only has three more papal names on it. I don't see any way that a Pope can build a bridge with radical Islamists. But, perhaps 30 years ago, no one could have believed that a Pope would be a staunch foe of communism after all the years of papal going-along-and-getting-along with Nazis and Fascists.
Are you thinking along the lines of a one-world religion?
