There’s been much debate among Christian writers on what writing “Christian Fiction” means. The artificial rules of Corporate Christian Publishing would eliminate many of the well-known writers who were Christians. These would include J.R.R. Tolkien and C.S. Lewis, as Donovan M. Neal writes. Many Christian writers – like writers of all beliefs – just want to write their story. A story informed by their beliefs (again, like all writers), but where their beliefs come through organically – not forced or contrived by some sort of formula. I’ve read books from all sorts of authors who want to lecture or preach to their readers. Really, it’s the difference between good and bad writing.
That’s not to say there isn’t anything good on the Christian Fiction shelf. There’s good and bad in all fiction markets and genres. Part of the debate also concerns the pros and cons of having your fiction labeled by your religion. If you are writing for a specific audience, then I suppose it’s fine, though religion is still bit of an unique way to classify fiction. Yes, there are other examples of targeting this or that demographic.
In the end, regardless of a writer’s beliefs, they shouldn’t spend their time figuring out how to be successful in getting certain people to read their books. They should write their story.
Readers should demand it.
