New wine must be put into new wineskins

Cyril says the questioners move from criticizing Christ's table fellowship to challenging his disciples' lack of fasting. Their comparison assumes that visible austerity proves fidelity to the law. Cyril does not belittle fasting: holy people use bodily discipline to restrain disordered passions. Yet Christ does not need fasting to conquer passions, because as God he is wholly free from them. His disciples, meanwhile, are being strengthened by sharing his grace. Their conduct must therefore be read from the presence and action of Christ, not measured by an external comparison that ignores who stands among them.

Cyril describes the Saviour's appearing as a great spiritual festival: human nature, formerly barren, is joined to Christ as a bride and made fruitful. Those called into his new evangelical way are therefore children of the Bridegroom. Chrysostom draws the practical conclusion that an hour of gladness should not be confused with an hour of mourning. Augustine adds that fasting can arise either from tribulation over sin or from joyful freedom as spiritual goods become sweeter than bodily ones. Jesus' answer orders both forms around himself. Discipline is not abolished, but the Bridegroom's presence determines what response is fitting now.

Augustine hears Christ foretelling the desolation his disciples will suffer when the Bridegroom is taken from them. Their sorrow will seek expression in fasting and lamentation until consolation is restored through the Holy Spirit. Cyril likewise treats the coming fast as an appointed response after the spiritual feast of Christ's visible presence. Ambrose guards the saying from becoming merely chronological: Christ promises to remain with his Church, so separation also occurs whenever sin draws a person away from him. Fasting then becomes more than deprivation of food. It is embodied longing, repentance, and a deliberate return toward communion with the Bridegroom.

Augustine connects the new cloth with the teaching of a spiritually renewed life. Its discipline is comprehensive: it loosens attachment not only to pleasant food but to every temporal delight that rules the heart. If one fragment is imposed upon people still devoted to their former habits, the teaching seems torn from its whole and cannot agree with the life beneath it. Ambrose similarly warns against mixing the actions of the old person with those of the new. Christ is not offering a religious patch that leaves the underlying garment untouched. Grace forms a coherent way of life whose outward practices belong together.

Gregory of Nyssa begins with the natural energy of newly drawn wine, whose warmth drives an active process within it. He sees this as an image of the new covenant: its teaching carries an excellence that old, unbelieving vessels cannot contain. The obstacle is not a defect in the wine but a soul unreceptive to divine wisdom, so the grace offered fails to bear fruit there. Augustine applies the image first to the apostles, who could not yet bear the full force of spiritual precepts. Christ prepares vessels as well as giving wine; renewal must accompany the gift if both are to endure.

Augustine says the apostles became new wineskins after the Lord's ascension, when desire for Christ's consolation renewed them through prayer and hope and they received the Holy Spirit. The command therefore concerns preparation, not novelty for its own sake. Bede identifies the wine with the inward fervor of faith, hope, and charity, while the garment represents good works visible outwardly. Grace renews the inner capacity from which faithful action flows. The final phrase matters: both wine and wineskins are preserved. God's gift does not erase the person who receives it; it heals and strengthens that person to hold a life previously beyond natural capacity.

Bede reads the old wine as the familiar life and inherited traditions to which Christ's hearers had become attached. Because their taste was already formed, they rejected the precepts of new grace and could not perceive the sweetness of spiritual teaching. Jesus' word recognizes that conversion meets real resistance: what is customary often feels better simply because it is known. Yet familiarity is not the measure of truth. The saying calls for patience without complacency. The heart must be renewed enough to taste what grace gives, rather than judging the Gospel solely by preferences established before the Bridegroom was welcomed.
