Jorge Bergoglio is not the Pope. That position still remains with Benedict XVI.
Hence why Bergoglio continues to spout utter heresies without relent.
Interregnums have happened before in history. Several lasted 2 years or more. And then there was the Western Schism (1378 - 1417) a period of 40 years in which there were two, sometimes three different simultaneous claimants to the papacy.
Fr. Pete, though in the past rather a Francis fan, evidently didn't think that was outside the range of possibility.
