Yeah, it's the hermeneutic of continuity crap, and the progression, aka "deeper understanding" of dogma, all to pretend they're not Modernists, believing that the change is not in Tradition but tradition.
100% false. V2 didn't merely change some accidentals. There was fundamental, substantial, transformative change ... and the core heresy of Vatican II is the new ecclesiology that guts Traditional (with a capital T) ecclesiology, the soteriology, and the subjectivism.
They keep saying that they haven't changed anything essential ... but it's 100% bullcrap. They can say it all they want, but that doesn't make it true.
