Don't feel bad. Recent surveys have found that a sizable percentage of the clergy are atheists and agnostics. Of course, most have been to seminary and studied what we actually know about the bible, rather than only what we talk about in Sunday school.
I've actually read some articles about that, and it makes complete sense. I've often wondered how anyone who has studied religion and has half a brain can still believe it.
I'm gonna start going again soon though..
