The sorry religious novel comes about when the writer supposes that because of his belief, he is somehow dispensed from the obligation to penetrate concrete reality. He will think that the eyes of the Church or of the Bible or of his particular theology have already done the seeing for him, and that his business is to rearrange this essential vision into satisfying patterns, getting himself as little dirty in the process as possible.
