Bringing the topic back from a broader debate on BoD.
1) I have never denounced classic BoD (as understood and articulated by Sts. Thomas, Bellarine, Alphonsus) as gravely erroneous or harmful to souls. I have in fact defended it against those charges. That quote you brought as evidence was taken out of context, where I'm denouncing the extended Pelagians notion of BoD, a notion which has NEVER been taught by the Magisterium in any way, shape, or form ... not even by these Doctors.
2) I have never held the position that every proposition contained in any text produced by the Magisterium is infallible and guaranteed inerrant. I have if fact repeatedly disagreed on this point with the dogmatic SVs who exaggerate the scope of infallibility (in their battle with R&R). They too fail to distinguish between infallibility in the strict sense and the overall substantial inerrancy of the Magisterium.
With these two distinctions, which I have explained several times already, and have been very firm about for years, the alleged "contradiction" (what Johnson called "hypocrisy") goes away. In your assertion of "contradiction" there's an implicit double straw-manning of my views: 1) attributing to me the denunciation of BoD as heretical or gravely erroneous that the Dimond Brothers make (and with which I have always disagreed) and 2) attributing to me the position of some dogmatic SVs that the Magisterium is absolutely inerrant.
What I have called heretical is the attribution of grave error to the Magisterium and also to the Church's Universal Discipline (particularly the Mass), and the litmus test for determining whether you've crossed this line is when you claim that the error is so grave that you can no longer remain in submission to and communion with the hierarchy without endangering your faith. If you claim that "in order to remain Catholic, I must separate from the hierarchy" ... THAT is what's heretical.
Had Vatican II and the NOM never happened, no Catholic would feel the need to start their own parallel church to disagree on the subject of BoD. You'd merely respectfully disagree with the popular interpretation of BoD and fight that as a theological debate from within the Church. [As an aside, Father Feeney didn't either. He was just unjustly kicked out, and his excommunication had nothing to do with BoD. Technically it was just because he failed to show up to a hearing in Rome, and it was unjust even on the legal grounds for why he failed to sow for the hearing, as Canon Law indicated he had the right to be informed of the charges so he could prepare an adequate defense. Nor was Father Feeney give the boot over BoD, a position which he categorized as an opinion and came up with later. He was kicked out because he simply upheld EENS dogma, while Cardinal Cushing openly denied it: "No salvation outside the Church? Nonsense."]
