Paul Burke says: whereas the Catholic Church (which I was taught does not change, unlike the secular world)

Well, let's talk about that tomorrow. Pope Francis is supposed to release a document tomorrow, and I'm expecting significant changes.

And, interestingly, I was taught in a Catholic seminary that the Catholic Church is constantly changing.

Here's a link to a Univision poll of Catholics in five continents. I think you'll find that Catholics aren't as mindlessly obedient to church teaching as one might think.
