He chose to lack for himself, that he may abound for all. The sobs of that appalling infancy cleanse me, those tears wash away my sins. Therefore, Lord Jesus, I owe more to your sufferings because I was redeemed than I do to works for which I was created. You see that he is in swaddling clothes. You do not see that he is in heaven. You hear the cries of an infant, you do not hear the lowing of an ox recognizing its Master, for the ox knows his Owner and the donkey his Master’s crib.
—Ambrose, Exposition of the Gospel of Luke: 2:41-42
