When Bart Campolo broke with the church almost five years ago, he immediately began to feel something missing.

It wasn't so much that the pastor's son no longer believed in God; he'd never been that much of a believer anyway.

What he missed, Campolo said, was what the church had represented to him: a place where like-minded people could gather for fellowship, to pursue moral justice, to help one another and to try to live good lives.

So the onetime United Methodist youth minister figured he'd try to keep doing that by presiding over what he cheerfully calls "a church for people who don't believe in God."

Campolo, 51, joined a growing movement of college "humanist chaplains," arriving at the University of Southern California last September.
