Antipope

“We have come to the point that even simple people with little knowledge of doctrinal issues understand that we have a non-Catholic pope, at least in the strict sense of the term. This poses some problems of a canonical nature.” – Archbishop Carlo Maria Vigano

Bishop Rene Gracida summed the “canonical” situation we are in with the doubtfulness of the Pope Benedict XVI resignation:

“[I]f the [Pope Benedict XVI] Renunciation is doubtful, then in virtue of canon 332 §2, it is invalid for lack of due manifestation”
