I'm glad that this concept demonstrates a small hint of contrition, but I don't think it goes far enough.
Looking at it another way, is this fair to the new pope? Anglican priests who retire will always move to another parish, so that their successors can take charge without being influenced by a predecessor.
Obviously former popes have different rules. But then again they have different views of morality too.
Now the question arises . . . does the non-country called The Vatican have an extradition treaty with any country in Europe? If so, it should expect a phone call quite soon.
If not, it doesn't deserve to be called a country, and the whole problem of the prosecution of its leading criminals is recursive.
