Abaddon said: or become so decrepit that he is no longer capable
In my opinion he already is decrepit and incapable. It's been like that for at least a decade. He's just a figurehead, the real power behind the curtains being the Vatican curia, specially Cardinal Ratzinger when it comes to "traditional family values". The sad thing is that this Pope has outlived most of the cardinals that were around when he was elected, so that the present College of Cardinals was almost entirely apointed by him, and are as conservative as he is. So I don't think the next Pope will be much better. And I don't agree that he is better than his predecessors; certainly not than John XXIII.
Anyways, Catholics couldn't care less, they just do what they feel like doing. They are not "book-oriented" like Protestants; their religiosity is more "adaptive", so to speak. That's why I think Catholicism has "The Truth" about Christianity (which is not to say that it is the true religion).
