And let me add I see the same potential for grave error in being dogmatically anti-Sedevacantism or anti-BOD.
Right, and I know where the inclination to be dogmatic about these conclusions comes from.
It's because the MAJOR PREMISES are dogmatic. Unfortunately, the line has blurred due to the failure to realize that there are minor premises and also that the logic itself is all of human origin. Father Jenkins points this out.
I am not dogmatically anti-R&R, but I am dogmatic indefectibilist. I defend the dogma that the Church is indefectible. But I have no problem with articulations of R&R such as were made by Archbishop Lefebvre, who explicitly maintained the dogmatic premise that what happened is not possible given the Holy Ghost's protection of the Church and the papacy. He simply refused to dogmatically hold out the EXPLANATION for how this Crisis happened (was Paul VI controlled, or drugged, or is sedevacantism true, I don't know -- per his famous speech). I have ZERO problem with that, since he upholds the dogmatic premise. I have ZERO problem with Father Chazal's explanation of the crisis. He's merely upholding the Cajetan/John of St. Thomas explanation vs. that of St. Robert Bellarmine, and he asserts that the V2 papal claimants have no authority. Whatever he wants to call it, I do not object ... and in fact I find his reasoning quite persuasive.
As for EENS, I'm a dogmatic defender of Tridentine ecclesiology. If someone wants to articulate a notion of BoD that maintains requirement to be joined to the VISIBLE Church AND upholds Trent's dogmatic teaching that the SACRAMENT of Baptism is necessary for salvation, then I'm not dogmatically opposed whatsoever. My problem is with articulations of BoD that are Pelagian and do not uphold the necessity of Baptism for salvation, or consider it optional, or a mere afterthought, "superfluous" as Trent dogmatically anathematized. If someone wants to believe in BoD for Catechumens, for instance, I have better things to argue about. I might disagree, but not dogmatically.
