"Place me like a seal over your heart, like a seal on your arm; for love is as strong as death, its jealousy unyielding as the grave." (Song of Songs 8:6)
The bride speaks her longing: if only you were to me like a brother, then I could kiss you in public without being despised. I would bring you to my mother's house and give you spiced wine to drink. His left arm would be under my head and his right arm would embrace me. Then the great declaration of love's nature: place me like a seal over your heart, like a seal on your arm; for love is as strong as death, its jealousy unyielding as the grave. It burns like blazing fire, like a mighty flame. Many waters cannot quench love; rivers cannot sweep it away. If one were to give all the wealth of one's house for love, it would be utterly scorned. The brothers ask about their little sister. The beloved closes: I am a wall and my breasts are like towers. Thus I have become in his eyes like one bringing contentment.
The Catechism identifies love as strong as death as the supreme Old Testament declaration of the permanence and power of covenant love, which finds its ultimate expression in the love of Christ who is stronger than death itself (CCC 1611).
Brothers and sisters, love is as strong as death. The Song ends where Job ends: at the boundary of death, looking for the love that can cross it. The resurrection of Christ is the answer to both books - the Redeemer who lives, the Love that death cannot extinguish, the Bridegroom who comes through the grave to claim the bride. Many waters cannot quench this love. Rivers cannot sweep it away.
Lord God, your love is as strong as death and stronger. Many waters have not quenched it. Seal it over our hearts. Through Christ our Lord. Amen.
