Suppose that the elected Popes were SUPPOSED to be in the place that they were. That is a rather interesting supposition, is it not?
Seeing as their election proved that fallible men - acting upon their own faults of greed and debauchery - were unreliable to be able to discern what is the leading of the Holy Spirit, I can agree that the purpose can indeed be interesting. ;o)
Perhaps this is one of the ways the Lord demonstrated the fallacy of the Roman Catholic Church's declarations of infallible Popes whose apostolic authority can be traced back to St. Peter and who demand all of Christendom's fealty because of it.
