I'm proud to likewise be among the ranks of evil atheist authors using the tool of genre for insidious means:
Oh, that *is* spiffy.
I have book coming out in 2008 from MonkeyBrain, Death of a Starship, wherein the primary protag (there are three) is an Orthodox priest. I went to a great deal of trouble to portray him sympathetically as a sincere person of faith, whose character and actions are informed by his beliefs. We'll see how people cope with that.
Oh, and this priest is essentially the "men in black" alien hunter for a far future star-spanning empire in a galaxy where the Fermi paradox continues unresolved.
