Many Christian clergy are mixed up themselves.
Probably, but many are right in the middle of life with both feet and Christian, Islamic, Buddhist, Hindu, Jewish, and other clerics handle very similar problems with very similar methods and can talk to each other as fellow professionals. They know, it usually happens when one has had a parish or ministry for some years, less often does it happen when one is handed a diploma at the age of 20-something and little practical responsibility yet for others' psychic spiritual health.
Like the ones that think gay mariage is okay? Yeah, I would say there are some "Christian" loons.
