So quickly does he gain forgiveness, that, as he is coming, and is still a great way off, his father meets him, gives him a kiss, which is the sign of sacred peace; orders the robe to be brought forth, which is the marriage garment, which if any one have not, he is shut out from the marriage feast; places the ring on his hand, which is the pledge of faith and the seal of the Holy Spirit; orders the shoes to be brought out, (Exodus 12:11) for he who is about to celebrate the Lord's Passover, about to feast on the Lamb, ought to have his feet protected against all attacks of spiritual wild beasts and the bite of the serpent; bids the calf to be slain, for
Christ our Passover has been sacrificed(1 Corinthians 5:7). For as often as we receive the Blood of the Lord, we proclaim the death of the Lord (1 Corinthians 11:26). As, then, He was once slain for all, so whenever forgiveness of sins is granted, we receive the Sacrament of His Body, that through His Blood there may be remission of sins.
Therefore most evidently are we bidden by the teaching of the Lord to confer again the grace of the heavenly sacrament on those guilty even of the greatest sins, if they with open confession bear the penance due to their sin (18-19).
