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.) For he was lying down. And I will go, for he was a long way off. To my father, because he was under a master of swine. But the other words are those of one meditating repentance in confession of sin, but not yet working it. For he does not now speak to his father, but promises that he will speak when he shall come. You must understand then that this “coming to the father” must now be taken for being established in the Church by faith, where there may yet be a lawful and effectual confession of sins. He says then that he will say to his father, Father.
