What a Church Wants

Read on Slate the other day an article reasoning out why it is that some people are willing to really commit to difficult religious practices: because people who are interested in religion want to hang out with other people who are highly committed to it.

It's called: Why Strict Churches are Strong

What I'd like to know is, first, how do you help people decide to make a commitment like that, and second, what happens to all the people who are only quasi-committed to a faith-organization?

Also, do any of you feel this way about church--that it's kind of all-or-nothing? And finally, do you think there's a liberal way of making a big commitment to a church? I think there is, but I think it takes on a different appearance than "strict churches."
