Ambrose of Milan
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.
He is dead who was. Therefore the Gentiles are not, the Christian is. Here however might be understood one individual of the human race; Adam was, and in him we all were. Adam perished, and in him we all have perished. Man then is restored in that Man who has died. It might also seem to be spoken of one working repentance, because he dies not who has not at one time lived. And the Gentiles indeed when they have believed are made alive again by grace. But he who has fallen recovers by repentance.
