Joking aside, I actually think this is a good idea. The last pope went on and on looking frailer and frailer and it was hardly fair on the guy, The current guy is going whilst he doesn't look so bad. I hope he manages to enjoy what life is left to him.
Of course the resignation could be an attempt to put the 'kiddy fiddling' behind the church. For right or wrong, Raztinger has been seen as the chief of those who tried to cover it all up and keep it from the police. Maybe he thinks if he goes he will take the problems with him and leave the church with a clean slate. Some hope!
now as to the predication that the next pope is to be the last and the world is going to end... sounds like we are living in interesting time, unless the guy who predicted this is Harold Camping in which case the fun is over.
