Christians . . . ought not to be threatened by fantasy and imagination. Great painting is not "photographic": think of the Old Testament art commanded by God. There were blue pomegranates on the robes of the priest who went into the Holy of Holies. In nature there are no blue pomegranates. Christian artists do not need to be threatened by fantasy and imagination, for they have a basis for knowing the difference between them and the real world "out there." The Christian is the really free person--he is free to have imagination. This too is our heritage. The Christian is the one whose imagination should fly beyond the stars.
