Fantasy writer L. B. Graham has some good comments on how Christian fiction is about mercy, not moralism (HT: Dave Bish):

Christianity is not about moralism, and Christian fiction shouldn’t be either. Christianity revolves, not around good behavior, but around God’s mercy shown to man in the death and resurrection of Christ. However, even though we know this to be theologically true, I think we struggle to remember this as we go about our daily lives, and one of the places where we really struggle to remember it is in our engagement with the arts in general, but as fiction is our topic, we’ll limit our reflection here to that.

I’m constantly surprised at how often fictional stories are judged to be Christian or not, based more or less on how well the characters behave themselves. Of course it is true that morality matters – God has taken great care to expound in some detail the moral laws which flow from and are an extension of His own character. It is also true, though, that the Bible itself is full of flawed men and women whom God used almost despite of rather than because of their moral triumphs. However, when Christian writers incorporate flawed heroes into their stories, men and women with moral failings of any significance, they are often left open to charges of having given dubious testimony to their Lord.

I’ve seen some pretty bad film and book reviews by Christians that seem to believe that the depiction of immorality is itself immoral, and come across some bad fiction that seems to be based on that idea. I don’t like the idea of “Christian fiction” as a distinct category; a Christian shouldn’t aim to write “Christian fiction”, but good fiction, fiction that is true, and beautiful, and good.

What makes fiction good is the moral context in which people’s actions are shown. That doesn’t mean that good fiction is fiction where every good action is always rewarded and every bad action is always punished, because that’s not true to the fallen world that we exist in. Sometimes we see justice in the here and now, sometimes we don’t. Sometimes we see something better, mercy and grace. Our choices for good and bad have consequences, and fiction can explore the complexities of that in a world that is damaged, yet still contains much good, and fiction written by a Christian has the potential to hint at happy ending that Christ will bring, when the world as it is and the world as it should be become the same thing.
