Luke 15:23

Rightly the flesh of the calf, because it is the priestly victim which was offered for sin. But he introduces him feasting, when he says, Be merry; to show that the food of the Father is our salvation; the joy of the Father the redemption of our sins. 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.

(ut sup.) Or the ring on the hand is a pledge of the Holy Spirit, because of the participation of grace, which is well signified by the finger. (ubi sup.) But the shoes on the feet are the preparation for preaching the Gospel, in order not to touch earthly things. (ubi sup.) Or, the fatted calf is our Lord Himself in the flesh loaded with insults. But in that the Father commands them to bring it, what else is this but that they preach Him, and by declaring Him cause to revive, yet unconsumed by hunger, the bowels of the hungry son? He also bids them kill Him, alluding to His death. For He is then killed to each man who believes Him slain. It follows, And let us eat.

(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.
