Peter J. Leithart on the poetry of sex :
Medieval Christians were obsessed with the Song of Songs. No book of the Bible received such intensely devoted attention in commentary and preaching. Bernard of Clairvaux preached eighty-six homilies on the Song and died just as he was getting started on chapter 3. The Song has a much-diminished place in the modern Christian imagination. The time is far past to reverse that trend, but it is worth reversing only if the Song is recovered as allegory .
