Maybe my memory is faulty but I seem to remember Cardinal Ratzinger affirming the infallibility of Ordinatio Sacerdatolis.
On Unam Sanctam I don’t think consulting a bunch of internet canonists is going to help much. I will say this though, “it is absolutely necessary for salvation that every human creature be subject to the Roman Pontiff” may not be saying exactly what you think it says. It is absolutely necessary for British citizenship for every human creature to be subject to the reigning monarch... doesn’t mean you have to like it or even acknowledge it. You could probably even vociferously deny it, wouldn’t actually change anything though.
Thanks for your non-answer. :-)
I'll be gone for a few hours but will attempt to research the Cardinal Ratzinger - Ordinatio Sacerdotalis thing later on.
I distinctly remember at the time he said it wasn't because when it came out "we" all started doing the happy dance and shouting "in your face" at the womyn-priestette people and then cardinal Ratzinger cut the legs out from under our unChristian glee. I believe what then developed was the statement that OS wasn't an exercise of the charism of infallibility because there was no refinement or clarification of dogma, it was something we already knew and fully understood JPII was just driving home the knife... er, so to speak.
As to my non answer... well, maybe it is. I'm not positive that the statement requires the assent of the individual reader. It may be a statement of fact as understood by the Catholic Church. I am my children's father even if some of them decide to go all emo on me in the future and claim otherwise. I think we've bounced off each other on this subject earlier and I sort of wondered if the interpretation of that line was dependent upon the intent of the currently reigning pontiff.
