Luke 15:22

Or the robe is the cloke of wisdom, by which the Apostle covers the nakedness of the body. But he received the best wisdom; for there is one wisdom which knew not the mystery. The ring is the seal of our unfeigned faith, and the impression of truth; concerning which it follows, And put a ring on his hand.

(non occ.) The father does not direct his words to his son, but speaks to his steward, for he who repents, prays indeed, but receives no answer in word, yet beholds mercy effectual in operation. For it follows, But the father said unto his servants, Bring forth the best robe, and put it on him.

(ubi sup.) Or he orders the ring to be given, which is the symbol of the seal of salvation, or rather the badge of betrothment, and pledge of the nuptials with which Christ espouses His Church. Since the soul that recovers is united by this ring of faith to Christ.

(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.

(de Quæst. Ev. l. ii. q. 33.) Or the best robe is the dignity which Adam lost; the servants who bring it are the preachers of reconciliation.
