I don’t think that speaks to the sociology, nor the theology etc. involved, at all.
Sorry. I just don’t.
Nancy and I met a couple some decades ago. They were converts, and as far as I could tell had no religion at all, no sense of Jesus beyond a kind of, let's all feel good and embrace liberal social causes. Unitarian Catholics? (I don't remember if they had a Subaru ...) (But then, I have a Subaru, so maybe that's not a good index ...)
Still, there was SOME hunger in them, or they wouldn't have joined up.
I guess my 'stance' with respect to the parade of half-hearted Catholics (and half-hearted Christians is the old Buddhist line, "If you hold a lotus to a rock long enough, who knows, maybe it will take root."
When Nancy and I got hitched, her maid of honor was a sort of classic "It doesn't matter what you believe as long as you're sincere," person. Very dear and sweet, but, wow, no awareness of anybody knocking at her door, and an active resistance to the idea that there was only one Lord worth the title.
7 years later she was doing exquisite calligraphies of Bible texts -- with real and grateful heart.
So I've learned to leave the whole conversion thing to God. He's really good at it. In the meantime, I'm glad the lotuses are at least NEAR the Rock, even when they vote for Obama and stuff.
