Thus it is right to fast, at times and from one point of view; but at other times, and from Jewish and formal motives, it is unnatural and mischievous. It is right when the Bridegroom is taken away, a phrase which certainly does not cover all this space between the Ascension and the Second Advent, since Jesus still reveals Himself to His own though not unto the world, and is with His Church all the days. Scripture has no countenance for the notion that we lost by the Ascension in privilege or joy. But when the body would fain rise up against the spirit, it must be kept under and brought into subjection (1 Cor. ix. 27). When the closest domestic joys would interrupt the seclusion of the soul with God, they may be suspended, though but for a time (1 Cor. vii. 5). And when the supreme blessing of intercourse with God, the presence of the Bridegroom, is obscured or forfeited through sin, it will then be as inevitable that the loyal heart should turn away from worldly pleasures, as that the first disciples should reject these in the dread hours of their bereavement.
Thus Jesus abolished the superstition that grace may be had by a mechanical observance of a prescribed regimen at an appointed time. He did not deny, but rather implied the truth, that body and soul act and counteract so that spiritual impressions may be weakened and forfeited by untimely indulgence of the flesh.
By such teaching, Jesus carried forward the doctrine already known to the Old Testament. There it was distinctly announced that the return from exile abrogated those fasts which commemorated national calamities, so that “the fast of the fourth month, and of the fifth, and of the seventh and of the tenth shall be to the house of Israel joy and gladness, cheerful feasts” (Zech. vii. 3, viii. 19). Even while these fasts had lasted they had been futile, because they were only formal. “When ye fasted and mourned, did ye at all fast unto me? And when ye eat, and when ye drink, do ye not eat for yourselves, and drink for yourselves?” (Zech. vii. 5, 6). And Isaiah had plainly laid down the great rule, that a fast and an acceptable day unto the Lord was not a day to afflict the soul and bow the head, but to deny and discipline our selfishness for some good end, to loose the bonds of wickedness, to undo the bands of the yoke, and to let the oppressed go free, to deal bread to the hungry, and to bring home the poor that is cast out (Isa. lviii. 5-7).
The true spirit of fasting breathes an ampler breath in any of the thousand forms of Christian self-denial, than in those petty abstinences, those microscopic observances, which move our wonder less by the superstition which expects them to bring grace than by the childishness which expects them to have any effect whatever.
III. Jesus now applies a great principle to all external rites and ceremonies. They have their value. As the wineskin retains the wine, so are feelings and aspirations aided, and even preserved, by suitable external forms. Without these, emotion would lose itself for want of restraint, wasted, like spilt wine, by diffuseness. And if the forms are unsuitable and outworn, the same calamity happens, the strong new feelings break through them, “and the wine perisheth, and the skins.” In this respect, how many a sad experience of the Church attests the wisdom of her Lord; what losses have been suffered in the struggle between forms that had stiffened into archaic ceremonialism and new zeal demanding scope for its energy, between the antiquated phrases of a bygone age and the new experience, knowledge and requirements of the next, between the frosty precisions of unsympathetic age and the innocent warmth and freshness of the young, too often, alas, lost to their Master in passionate revolt against restraints which He neither imposed nor smiled upon.
