There's this goofy revisionist narrative among people like you that there were 1900-some blissful years of consistent Catholic doctrine following the Apostolic Age, and then (cue the sinister music) Vatican II wrecked it all! Oh, that villainous Angelo Roncalli and his needless council!

Theological evolution has been happening all throughout the history of Christianity. Vatican II was simply the culmination of it. People like you just refuse to acknowledge that fact.

Okay, I've had enough of this. Moving on. Peace.
