Great story - I agree with other posters - solid, has a history about it.
Another thought is that this would integrate into some kinds of Sci Fi quite well - I'm thinking of Dark Heresy in particular. There are religious traditions buried in that (the Ordo Hereticus and so on) where this would fit - fight Chaos and so on.
In a more mundane way, remove the supernatural and give him the role of a local priest or some other reason to be popular - e.g. resistance to the government? Clues there in the refusal-to-politic part of the story.
Anyway, great and very useable character.
