Not sure about this feet washing business....doesn't seem terribly hygienic to me. But surely there is a more pressing use of soap and water that awaits our new Pope.
He could, for instance, start on the process of clearing out the Vatican and the church in general of its paedophiles, embezzlers, bank fraudsters, etc.
This might seem similar to the Herculean task of clearing out the Augean Stables but someone has to start somewhere. It would seem entirely logical to suggest that paedophilia has been going on in the church since Jesus joined the Bethlehem Cubs Scouts troop, and previous Popes have shown themselves totally inadequate to the task of dealing with it.
So, more power to the Pope's brushes !
