Jerome

Otherwise; By the old garment, and old skins, we must understand the Scribes and Pharisees; and by the piece of new cloth, and new wine, the Gospel precepts, which the Jews were not able to bear; so the rent was made worse. Something such the Galatians sought to do, to mix the precepts of the Law with the Gospel, and to put new wine into old skins. The word of the Gospel is therefore to be poured into the Apostles, rather than into the Scribes and Pharisees, who, corrupted by the traditions of the elders, were unable to preserve the purity of Christ’s precepts.
