Matthew 9:17

"Neither do men put new wine into old bottles." Seest thou His illustrations, how like the Old Testament? the garment? the wine skins? For Jeremiah too calls the people "a girdle," and makes mention again of "bottles" and of "wine." Thus, the discourse being about gluttony and a table, He takes His illustrations from the same. But Luke adds something more, that the new also is rent, if thou put it upon the old. Seest thou that so far from any advantage taking place, rather the mischief is increased? And while He speaks of the present, He foretells also the future; as that they shall hereafter be new but until that come to pass, nothing austere and grievous ought to be imposed on them. For he, saith Christ, that seeks to instill the high doctrines before the proper time, thenceforth not even when the time calls will he find them to his purpose, having once for all made them unprofitable. And this comes to pass not by any fault of the wine, nor of the deceivers, but from the unseasonable act of them that put it in. Hereby He hath taught us also the cause of those lowly expressions, which He was continually using in discourse with them. That is, by reason of their infirmity He said many things very short of His proper dignity; which John also pointing out, relates Him to have said, "I have many things to say unto you, but ye cannot bear them now." Here, that they might not suppose those things only to be which He had spoken, but might imagine to themselves others also, and far greater; He set before them their own infirmity, with a promise that when they should have become strong, He would tell them also the rest; which thing He saith here too, "Days will come, when the bridegroom shall be taken from them, and then shall they fast."

After two comparisons made, that of the wedding, and that of the undressed cloth, He adds a third concerning wine skins; Neither do men put new wine into old skins. By the old skins He means His disciples, who were not yet perfectly renewed. The new wine is the fulness of the Holy Spirit, and the depths of the heavenly mysteries, which His disciples could not then bear; but after the resurrection they became as new skins, and were filled with new wine when they received the Holy Spirit into their hearts. Whence also some said, These men are full of new wine. (Acts 2:13.)

(non occ.) This shows that the Apostles being hereafter to be replenished with newness of grace, ought not now to be bound to the old observances.

By these examples He shows that neither our souls nor bodies, being so weakened by inveteracy of sin, are capable of the sacraments of the new grace.

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.
