Ambrose of Milan — as excerpted in the Catena Aurea on Luke 15:11-16

“St. Luke has given three parables successively; the sheep which was lost and found, the piece of silver which was lost and found, the son who was dead and came to life again, in order that invited by a threefold remedy, we might heal our wounds. Christ as the Shepherd bears thee on His own body, the Church as the woman seeks for thee, God as the Father receives thee, the first, pity, the second, intercession, the third, reconciliation.”
