There’s a good piece in the Atlantic about Flannery O’Connor:
O’Connor was dismissive of any pressure, whether of religious or secular origin, for more “positive” fiction. She saw no contradiction between her faith and her art. Just the opposite: “Because I am a Catholic I cannot afford to be less than an artist.” However, she stated,
the novelist with Christian concerns will find in modern life distortions which are repugnant to him, and his problem will be to make these appear as distortions to an audience which is used to seeing them as natural.
