I don’t disagree with a word of it. However, as an aside, I recall somebody noting a few years back that it is curious that this toss-off phrase of Paul VI has acquired, for a certain subculture in the Church, all the force and weight of an infallible pronouncement, while actual magisterial teaching from Paul VI is often blown off as worthless. I wonder if anybody has ever made a study of how it is Catholics navigate such matters. The notion that Catholics actually order their thinking according to stuff the Pope teaches seems to me to be hopelessly naive. It appears much more accurate to see the average Catholic incorporates bits and pieces of what the Pope or the Magisterium teaches into the their thinking, often because it buttresses what he already wanted to believe.
I wonder how much I do that?
