It goes back to the modern, muddled mind, which started with subversive, occultic philosophers, such as Decartes. "I think, therefore I am."
BOD - "I desire baptism, therefore I receive it."
That's not reality.
Precisely ... it's closely related to the overall trend toward subjectivism. Bishop Willimason actually did a great job tracing the history of "subjectivism", from Descartes through Kant, and how that led to Modernism. Unfortunately, His Excellency failed to see the link between that and soteriology, subjectivization of the criteria for salvation. He did come closests to generally identifying the root problem with Vatican II, when he named it as "subjectivism", where even the materially true things in Vatican II are polluted or vitiated on account of being re-presented in a new subjectivist framework. Yes, we believe in the Holy Trinity. Who can object to that? Except that it's presented as some "fullness" of truth and not simply THE objective truth. That's what they mean by a "pastoral Council", where we don't teach anything new. They claim to be teaching the same things, but in a different way or different mode or couched in a different context. That context is subjectivism.
Even Religious Liberty flows from it, where if we please God and save our souls by following our (even erroneous) consciences, then since we have a right to please God and save our souls, we have a right to follow our (even erroneous) consciences. If I prevent some Muslim from practicing his religion so that he doesn't follow his conscience, I could in fact be causing his damnation. I've repeatedly stated that if I believe in the subjectivist soteriology held by nearly all Trads, I'd have no choice but to accept Vatican II (with the NOM being a separate issue).
