Awhile ago I visited an LDS church near my home and attended their young persons (18-22) bible discussion.   

By all appearances these young people were impressively psychologically mature, everyone friendly, well dressed, glad to be there, intelligent, and full  of zeal.    Trying to think of  ever visiting a Catholic church and seeing anything similar.  A group of 20 something Catholics who dress well (try to find just that!)  and freely choose to attend a bible discussion after mass?    Heck,  to spy a 20 something at mass is now and has always been a rare event.  

Other religions are doing something right that the Catholic church is not doing.   The Church can learn from them.
