But as it is, while modestly giving a reason why "the children of the bridegroom are unable to fast during the time the bridegroom is with them," but promising that "they should afterwards fast, when the bridegroom was taken away from them," He neither defended the disciples, (but rather excused them, as if they had not been blamed without some reason), nor rejected the discipline of John, but rather allowed it, referring it to the time of John, although destining it for His own time.
During the entire period that our Lord was in the midst of the world, he compared it with a bridal chamber and himself with the bridegroom. For the bridal guests cannot fast while the bridegroom is with them. …He called his disciples bridal guests because they are members of the church, and ministers of the feast, and heralds who invite those who sit at table.
The children of the Bridegroom also cannot fast, i. e. refuse nourishment to the soul, but live on every word which proceedeth out of the mouth of God.
(Orat. de Deit. Filii et SS.) 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. (Sap. 1:4.)
At the same time also is shown the difference between those who are zealous for the law and those who are for grace, that they who follow the law shall suffer eternal hunger of soul, while they who have received the word into the inmost soul, refreshed with abundance of heavenly meat and drink, can neither hunger nor thirst. And so they who fasted in soul murmured.
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.
But when are those days, in which Christ shall be taken away from us, since He has said, I will be with you alway, even unto the end of the world? But no one can take Christ away from you, unless you take yourself away from Him.
Lastly, it is spoken of the fast of the soul, as the context shows, for it follows, But he said, No man putteth a piece of a new garment upon an old. He calleth fasting an old garment, which the Apostle thought should be taken off, saying, Put off the old man with his deeds. (Col. 3:9.) In the same manner we have a series of precepts not to mix up the actions of the old and new man.
The weakness of man's condition is exposed when our bodies arc compared to the skins of dead animals.
“But the days will come when the Bridegroom shall be taken from them.” Which are these days in which Christ is taken from us, especially when he himself has said, “I shall be with you, even to the end of the world,” when he has said, “I will not leave you orphans"? For it is certain that if he were to leave us, we could not be saved. None can take Christ from you, unless you take yourself away. Your boasting will not take you away, nor arrogance, nor may you presume on the law for yourself. “For he came not to call the righteous, but sinners.” … The righteous are those who do not strike him who strikes them, who love their enemy. If we do not endure thus, the opposite is found. “I came not to call the righteous.” Christ does not call those who say they are righteous, for not knowing God and seeking to establish their own righteousness, they have not submitted themselves to the righteousness of God. Therefore the usurpers of righteousness are not called to grace. For if grace comes from penitence, surely one who scorns penitence renounces grace. Those who make themselves out to be holy will be wounded. The Bridegroom is taken from them. Neither Caiaphas nor Pilate took Christ from us. We cannot fast, because we have Christ, and we feast on the body and blood of Christ. For how does he who does not hunger seem to fast? How does he who does not thirst seem to fast? Then, how can he who drinks Christ thirst when he himself said, “Whosoever shall drink of the water that I will give him shall be thirsty no more”? Then what follows will declare the saying to concern the fasting of the spirit.
Then in this passage, fasting represents the old garment that the apostle thought should be taken off. He said, “Strip yourselves of the old man with his deeds,” so that we may put on the new man, which is renewed by the sanctification of baptism. Then the series of teachings is suited to the same garment, lest we mix the deeds of the old and the new man, when the physical exterior performs the works of the flesh. The inner man, which is reborn, should not have the varied appearance of old and new actions but be the same color as Christ. With zeal of mind, it should imitate him for whom he was cleansed by baptism. So let the discolored coverings of the mind, which are displeasing to the Bridegroom, be absent, for one who has not a wedding garment is displeasing to him. What can please the Bridegroom, except peace of spirit, purity of heart and clarity of mind?
(de Qu. Ev. l. ii. q. 18.) 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 unto them, Can ye make the children of the bridegroom fast when the bridegroom is with them?
(de Con. Ev. ii. c. 27.) Now this which Luke alone mentions, Ye 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.
(de Qu. Ev. ii. qu. 18.) 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.
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 thine eat, &c. (Lev. 15, prævaricationis.) As if they said, Ye 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 ye not fast, as they are wont to do who 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 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.
For the showing forth of our Saviour in this world was nothing else but a great festival, (πανήγυρις) 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.
To whom he himself said: Can you make the wedding guests fast while the bridegroom is with them? But days will come, and when the bridegroom is taken away from them, then they will fast in those days. The bridegroom is Christ, the bride is the Church. From this holy and spiritual union, the apostles were created. Hence, Mark the evangelist rightly calls them children of the wedding, not only of the bridegroom but also of the bride, wishing it to be understood that through the baptismal regeneration, they were taken into the right of divine generation. They cannot fast or mourn as long as they see the bridegroom in the chamber and know that he is with the bride. But when the wedding is over, and the time of the passion and resurrection arrives, then the children of the bridegroom will fast. However, Luke did not say like the others: Can the children of the bridegroom or the wedding fast or mourn, but can you make the children of the bridegroom fast (Luke 5)? He elegantly hinted that those who were speaking were the ones who would make the children of the bridegroom mourn and fast, since they were the ones who would kill the bridegroom. It is to be noted that this mourning of the absence of the bridegroom is not only now, that is, after the death and resurrection of the same bridegroom, but before his incarnation throughout the whole time of this age. For the early times of the Church, before the birth of the Virgin, had saints who desired the advent of the incarnation of Christ. But these times, since he ascended into heaven, have saints who desire his manifestation to judge the living and the dead. Nor did this desirable mourning of the Church rest somewhat, except as long as he was here with the disciples in the flesh. According to the laws of tropology, it is to be known that as long as the bridegroom is with us, we are in joy, and neither can we fast nor mourn. But when he has departed and fled from us because of sins, then fasting is to be proclaimed, then mourning is to be received.
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.
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 fervour 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.
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 desireth new, for he saith, 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.
