Jerome
Catena Aurea · Matthäusevangelium 9
Then came to him the disciples of John, saying, Why do we and the Pharisees fast oft, but thy disciples fast not? And Jesus said unto them, Can the children of the bridechamber mourn, as long as the bridegroom is with them? but the days will come, when the bridegroom shall be taken from them, and then shall they fast. No man putteth a piece of new cloth unto an old garment, for that which is put in to fill it up taketh from the garment, and the rent is made worse. Neither do men put new wine into old bottles; else the bottles break, and the wine runneth out, and the bottles perish: but they put new wine into new bottles, and both are preserved.
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.
