Oh yes, mimicking the Mormons is JUST what we Catholics want to do to get more young people in the pews. I suppose it never occurred to you that all those perky, well-dressed Mormon youth had no more choice in being present for bible class than they did in their choice of underwear:

"By all appearances these young people were impressively psychologically mature, everyone friendly, well dressed, glad to be there, intelligent, and full of zeal." Appearances can be deceiving.

Recently I talked with a woman who just moved to Salt Lake City. She told me that if you're not a Mormon people will be kind to you superficially but that they will never, ever invite you in to be part of their lives because to them you are damned, and associating with you makes them unclean.

Yes, we want to be JUST like Mormons. NOT!
