If you want my $.02 Benedict is the Pope. How can a pope resign? Imagine daddy Darth coming in one day and saying "Luke, I am no longer your father..."
They used the example of the "resignation" of St Celeste. Well, if you read the fine print, that pope did not resign, but the then-electorate said he resigned and locked him in a tower...
That being said, the situation in the Vatican is so loony-toony at this point it is not even worth discussing. It is like asking which is better: being shot in the head or run down by a fully loaded pickup...
Only an act of God is going to sort out this mess...
And that is both the good and the bad news.
PS I totally agree that the real Sr Lucia probably died about 1960, because the REAL Sr Lucia would have never set foot in a Novus Ordo chapel...
