Rorate Caeli has a story of Hans Küng declaring Benedict XVI schismatic over the issue of the possible SSPX unification.
Now while Hans Küng is somewhat of an expert on disobedience, heresy, and schism somehow I think he got this one wrong. Yeah what a surprise. He pins all this on the extremely debatable point that the Bishops and Priests of the SSPX were “definitely invalidly ordained.” Well not really debatable just plain Bravo Sierra. So I guess according to Mr. Küng attempts at ordaining women by a range of suspects are all valid, but the Bishops and Priest of the SSPX weren’t.
This is a kind of a “I’m rubber you’re glue, if I’m a schismatic than so are you.”
