Art is compatible with polytheism and with Christianity, but not with philosophical materialism; science is compatible with philosophical materialism and with Christianity, but not with polytheism. No artist or scientist, however, can feel comfortable as a Christian; every artist who happens also to be a Christian wishes he could be a polytheist; every scientist in the same position that he could be a philosophical materialist. And with good reason. In a polytheist society, the artists are its theologians; in a materialist society, its theologians are the scientists. To a Christian, unfortunately, both art and science are secular activities, that is to say, small beer.
No artist, qua artist, can understand what is meant by
To the imagination, the sacred is self-evident. It is as meaningless to ask whether one believes or disbelieves in Aphrodite or Ares as to ask whether one believes in a character in a novel; one can only say that one finds them true or untrue to life. To believe in Aphrodite and Axes merely means that one believes that the poetic myths about them dfo justice to the forces of sex and aggression as human beings experience them in nature and their own lives. That is why it is possible for an archaeologist who digs up a statuette of a god or goddess to say with fair certainty what kind of divinity it represents.
Similarly, to the imagination, the godlike or heroic man is self-evident. He does extraordinary deeds that the ordinary man cannot do, or extraordinary things happen to him.
The Incarnation, the coming of Christ in the form of a servant who cannot be recognized by the eye of flesh and blood, but only by the eye of faith, puts an end to all claims of the imagination to be the faculty which decides what is truly sacred and what is profane. A pagan god can appear on earth in disguise but, so long as he wears his disguise, no man is expected to recognize him nor can. But Christ appears looking just like any other man, yet claims that He is the Way, the Truth and the Life, and that no man can come to God the Father except through Him. The contradiction between the profane appearance and the sacred assertion is impassible to the imagination.
It is impossible to represent Christ on the stage. If he is made dramatically interesting, he ceases to be Christ and turns into a Hercules or a Svengali. Nor is it really possible to represent him in the visual arts for, if he were visually recognizable, he would be a god of the pagan kind. The best the painter can do is to paint either the Bambino with the Madonna or the dead Christ on the cross, for every baby and every corpse seems to be both individual and universal,
To a Christian, the godlike man is not the hero who does extraordinary deeds, but the holy man, the saint, who does good deeds. But the gospel defines a good deed as one done in secret, hidden, so far as it is possible, even from the doer, and forbids private prayer and fasting in public. This means that art, which by its nature can only deal with what can and should be manifested, cannot portray a saint.
There can no more be a "Christian" art than there can be a Christian science or a Christian diet. There can only be a Christian spirit in which an artist, a scientist, works or does not work. A painting of the Crucifixion is not necessarily more Christian in spirit than a still life, and may very well be less.
I sometimes wonder if there is not something a bit questionable, from a Christian point of view, about all works of art which make overt Christian references. They seem to assert that there is such a thing as a Christian culture, which there cannot be. Culture is one of Caesar's things. One cannot help noticing that the great period of "religious" painting coincided with the period when the Church was a great temporal power.
The only kind of literature which has gospel authority is the parable, and parables are secular stories with no overt religious reference.
There are many hymns I like as one likes old song hits, because, for me, they have sentimental associations, but the only hymns I find poetically tolerable are either versified dogma or Biblical ballads.
