Drama usually bases itself on the bedrock of original sin, whether the writer thinks in theological terms or not. Then, too, any character in a serious novel is supposed to carry a burden of meaning larger than himself. The novelist doesn’t write about people in a vacuum; he writes about people in a world where something is obviously lacking, where there is the general mystery of incompleteness and the particular tragedy of our own times to be demonstrated, and the novelist tries to give you, within the form of the book, a total experience of human nature at any time.
For this reason, the greatest dramas naturally involve the salvation or loss of the soul. Where there is no belief in the soul, there is very little drama. The Christian novelist is distinguished from his pagan colleagues by recognizing sin as sin. According to his heritage, he sees it not as a sickness or an accident of the environment, but as a responsible choice of offense against God which involves his eternal future. Either one is serious about salvation or one is not. And it is well to realize that the maximum amount of seriousness admits the maximum amount of comedy.
Only if we are secure in our beliefs can we see the comical side of the universe. One reason a great deal of our contemporary fictions is humorless is because so many of these writers are relativists and have to be continually justifying the actions of their characters on a sliding scale of values.
