Augustine of Hippo
Catena Aurea · Lukasevangelium 15
And when he came to himself, he said, How many hired servants of my father’s have bread enough and to spare, and I perish with hunger! I will arise and go to my father, and will say unto him, Father, I have sinned against heaven, and before thee, And am no more worthy to be called thy son: make me as one of thy hired servants. And he arose, and came to his father. But when he was yet a great way off, his father saw him, and had compassion, and ran, and fell on his neck, and kissed him. And the son said unto him, Father, I have sinned against heaven, and in thy sight, and am no more worthy to be called thy son. But the father said to his servants, Bring forth the best robe, and put it on him; and put a ring on his hand, and shoes on his feet: And bring hither the fatted calf, and kill it; and let us eat, and be merry: For this my son was dead, and is alive again; he was lost, and is found. And they began to be merry.
(ubi sup.) Or running he fell upon his neck; because the Father abandoned not His Only-Begotten Son, in whom He has ever been running after our distant wanderings. For God was in Christ reconciling the world unto himself. (2 Cor. 5:19.) But to fall upon his neck is to lower to his embrace His own Arm, which is the Lord Jesus Christ. But to be comforted by the word of God’s grace unto the hope of pardon of our sins, this is to return after a long journey to obtain from a father the kiss of love. But already planted in the Church, he begins to confess his sins, nor says he all that he promised he would say. For it follows, And his son said unto him, &c. He wishes that to be done by grace, of which he confesses himself unworthy by any merits of his own. He does not add what he had said, when meditating beforehand, Make me as one of thy hired servants. For when he had not bread, he desired to be even a hired servant, which after the kiss of his father he now most nobly disdained.
