John Chrysostom
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.
(Hom. de Patre et duobus Filiis.) Or he bids them put shoes on his feet, either for the sake of covering the soles of his feet that he may walk firm along the slippery path of the world, or for the mortification of his members. For the course of our life is called in the Scriptures a foot, and a kind of mortification takes place in shoes; inasmuch as they are made of the skins of dead animals. He adds also, that the fatted calf must be killed for the celebration of the feast. For it follows, And bring the fatted calf, that is, the Lord Jesus Christ, whom he calls a calf, because of the sacrifice of a body without spot; but he called it fatted, because it is rich and costly, inasmuch as it is sufficient for the salvation of the whole world. But the Father did not Himself sacrifice the calf, but gave it to be sacrificed to others. For the Father permitting, the Son consenting thereto by men was crucified.
