Catena Aurea on Luke 15:17–24: Augustine of Hippo

Or running he fell upon his neck; because the Father abandoned not His Only-Begotten Son, in whom He has ever been running after our distant wanderings. For God was in Christ reconciling the world unto himself. (2 Cor. 5:19.) But to fall upon his neck is to lower to his embrace His own Arm, which is the Lord Jesus Christ. But to be comforted by the word of God’s grace unto the hope of pardon of our sins, this is to return after a long journey to obtain from a father the kiss of love. But already planted in the Church, he begins to confess his sins, nor says he all that he promised he would say. For it follows, And his son said unto him, &c. He wishes that to be done by grace, of which he confesses himself unworthy by any merits of his own. He does not add what he had said, when meditating beforehand, Make me as one of thy hired servants. For when he had not bread, he desired to be even a hired servant, which after the kiss of his father he now most nobly disdained.
