how the song functions (leithart)

(from this article by Peter Leithart, on the Song of Solomon)

The Song helps us relearn what nearly every civilization before ours already knew: Sex is allegory, and as allegory it is metaphysics and theology and cosmology. For Christians, sexual difference and union is a type of Christ and the church: How could an erotic poem (and in the Bible!) be anything but allegory? From the Song we relearn that poetic metaphor does not add meaning to what is itself mere chemistry and physics. Nor is erotic poetry a euphemistic cover for Victorian embarrassment. Poetry elucidates the human truth of human sexuality, and it seems uniquely capable of doing so. Only as allegory does the Song have anything to teach us about sex. Only as allegory can the Song play its central role in healing our sexual imaginations.
