I know. I'm just "more Catholic than the Pope." Pharisee wanting a small church getting smaller, repel boarders, fortress Catholic, et cetera, et cetera, et cetera.
Whatever. Once I manage to make sense of this, I might make some progress:
"The Council Fathers knew that being open to modern culture meant religious ecumenism and dialogue with non-believers. But afterwards very little was done in that direction."
That's certainly an interesting take. From what I can see, it certainly is happening, right now, albeit with sometimes...interesting results.
