Ambrose on the Song of Songs

Comment on 8:1-4

What are the breasts of the church except the sacrament of baptism? And well does he say "sucking," as if the baptized were seeking him as a draught of snowy milk. "Finding you without," he says, "I shall kiss you," that is, finding you outside the body, I embrace you with the kiss of mystical peace. No one shall despise you; no one shall shut you out. I will introduce you into the inner sanctuary and hidden places of Mother Church, and into all the secrets of mystery, so that you may drink the cup of spiritual grace.
