To demand the art forms of yesterday in either word systems or art is a bourgeois error. It cannot be assumed that if a Christian painter becomes "more Christian" he will necessarily become more and more like Rembrandt. . . .

Christian art today should be twentieth-century art. Art changes. Language changes. The preacher's preaching today must be twentieth-century language communication, or there will be an obstacle to being understood. And if a Christian's art is not twentieth-century art, it is an obstacle to his being heard. It makes him different where there is no necessity for difference. A Christian should not, therefore, strive to copy Rembrandt or Browning.
