Set me as a seal upon your heart, as a seal upon your arm: for love is as strong as death; jealousy is cruel as the grave: its flames are flames of fire, a most vehement flame.
All Commentaries on Song of Songs 8:6 Go To Song of Songs 8
Ambrose of Milan
AD 397
Christ is the seal on the forehead, the seal in the heart—on the forehead that we may always confess him, in the heart that we may always love him, and a sign on the arm that we may always do his work. Therefore let his image shine forth in our profession of faith, let it shine forth in our love, let it shine forth in our works and deeds so that, if it is possible, all his beauty may be represented in us. Let him be our head, because “the head of man is Christ”; let him be our eye, that through him we may see the Father; let him be our voice, that through him we may speak to the Father; let him be our right hand, that through him we may bring our sacrifice to God the Father. He is also our seal, which is the mark of perfection and of love, because the Father, loving the Son, set his seal on him, just as we read, “Upon him the Father, God himself, has set his seal.”
And so Christ is our love. Good is love, since it has offered itself to death for transgressions; good is love, which has forgiven sins. And so let our soul clothe itself with love, and love of a kind that is “strong as death.” For just as death is the end of sins, so also is love, because one who loves the Lord ceases to commit sin. For “charity thinks no evil and does not rejoice over wickedness, but endures all things.” For if one does not seek his own goods, how will he seek the goods of another? Strong, too, is that death through the bath through which every sin is buried and every fault forgiven.
