[Doc Faustus]

Christian horror is very common. Stephen King's books for example, has a strong backbone of faith. Yes, they have a distinct cosmology, but there is strong black and white and the Stand is as Christian as Paradise Lost. Also, let's not forget Dante's Divine Comedy. All horror originated from theological places, from the transformations in Ovid's Metamorphosis to Dracula's assault on Victorian values. I'm a horror/bizarro writer and my work is influenced by Gnostic beliefs that I hold. Yes, it can sell, but you need to watch out for the same things that hurt Christian music such as using faith to sell inferior product (IDOLATRY!) and losing the soul of your work in propaganda. If you can't say something about Christianity that it doesn't say about itself, you shouldn't bother. Good job keeping your beliefs. Hopefully the work was good enough that you didn't shame them.
