Luke 5:35

As soon as they have received the first answer from Christ, they proceed from one thing to another, with the intent to show that the holy disciples, and Jesus Himself with them, cared very little for the law. Hence it follows, Why do the disciples of John fast, but you eat, &c. As if they said, You eat with publicans and sinners, whereas the law forbids to have any fellowship with the unclean, but compassion comes in as an excuse for your transgression; why then do you not fast, as they are wont to do who ho wish to live according to the law? But holy men indeed fast, that by the mortification of their body they may quell its passions. Christ needed not fasting for the perfecting of virtue, since as God He was free from every yoke of passion. Nor again did His companions need fasting, but being made partakers of His grace without fasting they were ere strengthened in all holy and godly living. For when Christ fasted for forty days, it was not to mortify His passions, but to manifest to carnal men the rule of abstinence.

Now Luke evidently relates that this was spoken not by men of themselves, but by others concerning them. How then does Matthew say, Then came to him the disciple of John, saying, Why do we and the Pharisees fast; unless that they themselves also came, and were all eager, as far as they were able, to put the question to Him?

Now there are two fasts, one is in tribulation, to propitiate God for our sins; another in joy, when as carnal things delight us less, we feed the more on things spiritual. The Lord therefore being asked why His disciples did not fast, answered as to each fast. And first of the fast of tribulation; for it follows, And he said to them, Can you make the children of the bridegroom fast when the bridegroom is with them?

As if He should say, The present time is one of joy and gladness, sorrow must not then be mixed up with it.

For the showing forth of our Savior in this world was nothing else but a great festival, spiritually uniting our nature to Him as His bride, that she who was formerly barren might become fruitful. The children of the Bridegroom then are found to be those who have been called by Him through a new and evangelical discipline, but not the Scribes and Pharisees, who observe only the shadow of the law.

Now this which Luke alone mentions, You cannot make the children of the bridegroom fast, is understood to refer to those very men who said that they would make the children of the Bridegroom mourn and fast, since they were about to kill the Bridegroom.

Having granted to the children of the Bridegroom that it was not fitting that they should be troubled, as they were keeping a spiritual feast, but that fasting should be abolished among them, He adds as a direction, But the days shall come when the Bridegroom shall be taken from them, and then shall they fast in those days.

As if He said, Then shall they be desolate, and in sorrow and lamentation, until the joy of consolation shall be restored to them by the Holy Spirit.

Or, That fast is not given up whereby the flesh is mortified, and the desires of the body chastened. (For this fast commends us to God.) But we cannot fast who have Christ, and banquet on the flesh and blood of Christ.

The children of the Bridegroom also cannot fast, i.e. refuse nourishment to the soul, but live on every word which proceeds out of the mouth of God.

But when are those days, in which Christ shall be taken away from us, since He has said, I will be with you always, even to the end of the world? But no one can take Christ away from you, unless you take yourself away from Him.

For as long as the Bridegroom is with us we both rejoice, and can neither fast nor mourn. But when He has gone away through our sins, then a fast must be declared and mourning be enjoined.

Lastly, it is spoken of the fast of the soul, as the context shows, for it follows, But be said, No man puts a piece of a new garment upon an old. He calls fasting an old garment, which the Apostle thought should be taken off, saying, Put off the old man with his deeds. In the same manner we have a series of precepts not to mix up the actions of the old and new man.

Or else, The gift of the Holy Spirit being received, there is a kind of fast, which is of joy, which they who are already renewed to a spiritual life most seasonably celebrate. Before they receive this gift, He says they are as old garments, to which a new piece of cloth is most unsuitably sewed on, i.e. any part of the doctrine which relates to the soberness of the new life; for if this takes place, the very doctrine itself also is in a measure divided, for it teaches a general fast not from pleasant food only, but from all delight in temporal pleasures, the part of which that appertains to food He said ought not to be given to men still devoted to their old habits, for therein seems to be a rent, and it agrees not with the old. He says also, that they are like to old skins, as it follows, And no one puts wine into old skins.

The weakness of man’s condition is exposed when our bodies are compared to the skins of dead animals.

But the Apostles are compared to old skins, who are more easily burst with new wine, i.e. with spiritual precepts, than contain them. Hence it follows, Else the new wine will burst the skins, and the wine will be spilled. But they were new skins at that time, when after the ascension of the Lord they received the Holy Spirit, when from desire of His consolation they were renewed by prayer and hope. Hence it follows, But the new wine must be put into new bottles, and both are preserved.

Inasmuch as wine refreshes us within, but garments cover us without, the garments are the good works which we do abroad, by which we shine before men; wine, the fervor of faith, hope, and charity. Or, The old skins are the Scribes and Pharisees, the new piece and the new wine the precepts of the Gospel.

For wine newly drawn forth, evaporates on account of the natural heat in the liquor, throwing off from itself the scum by natural action. Such wine is the new covenant, which the old skins because of their unbelief contain not, and are therefore burst by the excellence of the doctrine, and cause the grace of the Spirit to flow in vain; because into an evil soul wisdom will not enter.

But to every soul which is not yet renewed, but goes on still in the old way of wickedness, the sacraments of new mysteries ought not to be given. They also who wish to mix the precepts of the Law with the Gospel, as the Galatians did, put new wine into old bottles. It follows, No man also having drank old wine straightway desires new, for he said, the old is better. For the Jews, imbued with the taste of their old life, despised the precepts of the new grace, and being defiled with the traditions of their ancestors, were not able to perceive the sweetness of spiritual words.

The publican who was chosen by the Lord, he adduces for a proof that he was chosen as a stranger to the law and uninitiated in Judaism, by one who was an adversary to the law. The case of Peter escaped his memory, who, although he was a man of the law, was not only chosen by the Lord, but also obtained the testimony of possessing knowledge which was given to him by the Father. He had nowhere read of Christ’s being foretold as the light, and hope, and expectation of the Gentiles! He , however, rather spoke of the Jews in a favourable light, when he said, “The whole needed not a physician, but they that are sick.” For since by “those that are sick” he meant that the heathens and publicans should be understood, whom he was choosing, he affirmed of the Jews that they were “whole” for whom he said that a physician was not necessary. …

For, so far as pertains to fasts, they oppose to us the definite days appointed by God: as when, in Leviticus, the Lord enjoins upon Moses the tenth day of the seventh month (as) a day of atonement, saying, “Holy shall be to you the day, and ye shall vex your souls; and every soul which shall not have been vexed in that day shall be exterminated from his people.” At all events, in the Gospel they think that those days were definitely appointed for fasts in which “the Bridegroom was taken away;” and that these are now the only legitimate days for Christian fasts, the legal and prophetical antiquities having been abolished: for wherever it suits their wishes, they recognise what is the meaning of “the Law and the prophets until John.” Accordingly, (they think) that, with regard to the future, fasting was to be indifferently observed, by the New Discipline, of choice, not of command, accord …

XVIII . Do you therefore fast on the days of the passover, beginning from the second day of the week until the preparation, and the Sabbath, six days, making use of only bread, and salt, and herbs, and water for your drink; but do you abstain on these days from wine and flesh, for they are days of lamentation and not of feasting. Do ye who are able fast the day of the preparation and the Sabbath-day entirely, tasting nothing till the cock-crowing of the night; but if any one is not able to join them both together, at least let him observe the Sabbath-day; for the Lord says somewhere, speaking of Himself: “When the bridegroom shall be taken away from them, in those days shall they fast.” In these days, therefore, He was taken from us by the Jews, falsely so named, and fastened to the cross, and “was numbered among the transgressors.”
