I agree that many (not all) sedes think an authentic/ordinary/non-infallible magisterium destroys their position. But it doesn't. Admitting that there is a fallible magisterium only highlights a minor logical error of sedeism (i.e. the pope can't become a heretic, which is a debatable point). The fact that the magisterium can be fallible and infallible (depending on language used) actually STRENGTHENS the sede position overall. Because it proves that the V2 anti-popes are heretics because of their PERSONAL heresy and not because the Church has erred or defected.
So this whole V2 crisis does NOT tarnish the purity of Christ's Bride, nor Her holiness of doctrine, nor Her clarity of Truth. No, because The Church has not taught/required evil or error. The anti-popes (through devilish trickery and legal mind games) promoted, condoned, and allowed error but never required, commanded or officially taught such.
A very important distinction which answers the apparent contradictions of our day. Fr Chazal would agree with this. +Williamson would agree with this. Fr Wathen would agree with this. +ABL would agree with this. All current sedes should agree with this.
It occurs to me that what we are all arguing about for the last 50 years is the *best explanation* of the crisis. And since such a crisis has a spiritual mystery component to it (because it concerns the mystery of salvation and also of the doctrines of indefectibility/infallibility), no one besides the Church can ultimately adequately and completely explain it. So we wait for the perfect explanation. But in the meantime, we should all agree on the distinction (but we won't, haha).
Well put. I believe you hit on the nail what many people should focus on.
I as a private sede agree that (from what my poor brain can comprehend) Vatican II did not invoke the infallible teaching authority of the Church. I think everyone should be able to agree on that.
The part most people here seem to really disagree on is the definition and explanation of "ordinary teaching authority" of the Church and it's effect and authority in respect to us.
It is the difference between dogma and doctrine. A dogma is a solemnly proclaimed statement about a matter of Faith or Morals. A doctrine is a religious belief held by the Church which has never been officially proclaimed excathedra but which we a Catholics hold through the traditions and customs of the Church and the authority of Her hierarchy and ministers.
The issue which people really should be discussing then is whether a person is obliged to accept all doctrines of the Church that have not been declared ex cathedra as doctrine.
In my opinion it seems that until something has not been declared a dogma it is not "de fide" meaning that you would be considered outside the Church for not believing it because it is essential to the Faith. And we know that a pope cannot see in such matters. Saint Robert Bellarmine argued that even anti-popes never did.
Yet, doctrinal matters given through the normal ordinary teaching authority of the Church are something that all faithful Catholics should give assent to. For example, if one's bishop approved or disapproved of a book and gave it a "prohibitation" or "imprimatur" people should follow that. Could a bishop fail and ever be wrong, yes. And normally one would appeal to the Pope in such matters. The issue is that when the person standing in as Pope says and asks for such things we have only God to appeal to.
God save us!
