Agent Deborah Levine Herman of the Herman Literary Agent has written a book called Spiritual Writing. In it she lists agents who represent spiritual books of all categories, so I thought I'd put some of that info here. Maybe it could be stickied. I'm not going to add their websites, takes too long to look them all up, so please do more research yourself:
