Thanks for posting this. (I have no idea if this is your blog, and frankly don’t care.) I think we always run into difficulty when we use the word “Christian” as an adjective. Christian writer. Christian movie. Christian literature. Christian environment. That language both raises and lowers expectations and seldom provides any kind of accurate or valuable additional information.
Perhaps your solution—endeavoring to create a masterful work of art—is best. That puts the Christian writer on the same ground as the non-Christian writer committed to the same ideal, making a real dialog more possible.
For a great discussion of Walker Percy and some insight into what it means to be a “Christian” writer, here is a long (but worth it if you can take the time) Youtube video: https://www.youtube.com/watch?v=Sz7RKYhsAM4
When I read this, I thought it curious that if we were to replace "Christian" with "adult"--adult writer. adult movie. adult literature. adult environment--there is no ambiguity, even though "adult" is a euphemism.
The reason "Christian" as an adjective is ambiguous is two-fold. First, in common parlance, "Christian" covers every way of thinking from Westboro Baptist to United Church of Christ, so that practically any stance can refer to itself as "Christian," regardless of doctrinal integrity.
Second, "Christian" in the arts has become, not only a statement of theology, but a statement of niche marketing. It is presumed that only hardcore Christians will read "Christian" novels, listen to "Christian" music, and watch "Christian" movies, and certainly no one with a truly literary or (educated) musical bent would deign to stoop so low as to sully him/herself with such pandering-to-the-pews drivel.
