Matthew 6:17

As therefore, when He said, "Let not thy left hand know what thy right hand doeth," it was not of hands that He was speaking, but of the duty of being strictly concealed from all; and as when He commanded us to enter into our closet, not there alone absolutely, nor there primarily, did He command us to pray, but He covertly intimated the same thing again; so likewise here, in commanding us "to be anointed," He did not enact that we positively must anoint ourselves; for then we should all of us be found transgressors of this law; and above all, surely, they who have taken the most pains to keep it, the societies of the monks, who have taken up their dwelling on the mountains. It was not this then that He enjoined, but, forasmuch as the ancients had a custom to anoint themselves continually, when they were taking their pleasure and rejoicing (and this one may see clearly from David and from Daniel); He said that we were to anoint ourselves, not that we should positively do this, but that by all means we might endeavor, with great strictness, to hide this our acquisition. And to convince thee that so it is, He Himself, when by action exhibiting what He enjoined in words, having fasted forty days, and fasted in secret, did neither anoint nor wash Himself: nevertheless, though He did not these things, He most assuredly fulfilled the whole without vainglory. It is this then that He enjoins on us likewise, both bringing before us the hypocrites, and by a twice repeated charge dissuading the hearers.

(ubi sup.) A question is here wont to be raised; for none surely would literally enjoin, that, as we wash our faces from daily habit, so we should have our heads anointing when we fast; a thing which all allow to be most disgraceful. (ubi sup.) Or; by the head we rightly understand the reason, because it is preeminent in the soul, and rules the other members of the man. Now anointing the head has some reference to rejoicing. Let him therefore joy within himself because of his fasting, who in fasting turns himself from doing the will of the world, that he may be subject to Christ.

(Hom. in Ev. xvi. 6.) For God approves that fasting, which before His eyes opens the hands of alms. This then that you deny yourself, bestow on another, that wherein your flesh is afflicted, that of your needy neighbour may be refreshed.

(ap. Anselm.) The Lord having taught us what we ought not to do, now proceeds to teach us what we ought to do, saying, When thou fastest, anoint thy head, and wash thy face. (ord.) That is, to thy heavenly Father, who is unseen, or who dwells in the heart through faith. He fasts to God who affliets himself for the love of God, and bestows on others what he denies himself. (ord.) Behold how every thing in the New Testament is not to be taken literally. It were ridiculous to be smeared with oil when fasting; but it is behoveful for the mind to be anointed with the spirit of His love, in whose sufferings we ought to partake by afflicting ourselves.

But thou, when thou fastest, anoint thy head, and wash thy face. Here the fitting manner of fasting is set forth, and regarding this he does three things. First, he sets forth the manner; secondly, he assigns the reason; thirdly, the benefit. He says, therefore, …

"But thou, when thou fastest, anoint thine head, and wash thy face; that thou appear not unto men to fast, but unto thy Father Who is in secret: and thy Father Who seeth in secret shall reward thee openly." Men of old would anoint themselves …

But thou, when thou fastest,.... Christ allows of fasting, but what is of a quite different kind from that of the Jews; which lay not in an outward abstinence from food, and other conveniences of life, and refreshments of nature; but in an abstinence from sin, in acknowledgment and confession of it; and in the exercise of faith and hope in God, as a God pardoning iniquity, transgression and sin; wherefore cheerfulness, and a free use of the creatures, without an abuse of them, best became such persons.

But thou when thou fastest, anoint ... - That is, appear as you do daily. Do not assume any new appearance, or change your visage or dress. The Jews and all neighboring nations were much in the habit of washing and anointing their bodies. This washing was performed at every meal; and where it could be effected, the head, or other parts of the body, was daily anointed with sweet or olive oil.

There are three subjects brought before us in this part of our Lord’s sermon on the mount. These three are fasting, worldliness, and singleness of purpose in religion. Fasting, or occasional abstinence from food in order to bring the body into subjection to the spirit, is a practice frequently mentioned in the Bible, and generally in connection with prayer. David fasted when his child was sick; Daniel fasted when he sought special light from God; Paul and Barnabas fasted when they appointed elders; Esther fasted before going in to Ahasuerus.

But thou, when thou fastest, anoint thine head, and wash thy face--as the Jews did, except when mourning (Da 10:3); so that the meaning is, "Appear as usual"--appear so as to attract no notice.

There are three subjects brought before us in this part of our Lord’s sermon on the mount. These three are fasting, worldliness, and singleness of purpose in religion. Fasting, or occasional abstinence from food in order to bring the body into subjection to the spirit, is a practice frequently mentioned in the Bible, and generally in connection with prayer. David fasted when his child was sick; Daniel fasted when he sought special light from God; Paul and Barnabas fasted when they appointed elders; Esther fasted before going in to Ahasuerus. It is a subject about which we find no direct command in the New Testament. It seems to be left to everyone’s discretion, whether he will fast or not. In this absence of direct command we may see great wisdom. Many a poor man never has enough to eat, and it would be an insult to tell him to fast: many sick people can hardly be kept well with the closest attention to diet, and could not fast without bringing on illness. It is a matter in which everyone must be persuaded in their own mind, and not rashly condemn others who do not agree with him. One thing only must never be forgotten: those who fast should do it quietly, secretly and without ostentation. Let them not “appear to men to fast.” Let them not fast to man, but to God. Worldliness is one of the greatest dangers that beset man’s soul. It is no wonder that we find our Lord speaking strongly about it: it is an insidious, specious, plausible enemy; it seems so innocent to pay close attention to our business! It seems so harmless to seek our happiness in this world, so long as we keep clear of open sins! Yet here is a rock on which many make shipwrecked to all eternity. They “lay up treasure on earth,” and forget to “lay up treasure in heaven.” May we all remember this! Where are our hearts? What do we love best?

Anoint thine head and wash thy face - These were forbidden in the Jewish canon on days of fasting and humiliation; and hypocrites availed themselves of this ordinance, that they might appear to fast. Our Lord, therefore, cautions us against this: as if he had said, Affect nothing - dress in thy ordinary manner, and let the whole of thy deportment prove that thou desirest to recommend my soul to God, and not thy face to men. That factitious mourning, which consists in putting on black clothes, crapes, etc., is utterly inconsistent with the simplicity of the Gospel of Christ; and if practised in reference to spiritual matters, is certainly forbidden here: but sin is so common, and so boldly persisted in, that not even a crape is put on, as an evidence of deploring its influence, or of sorrow for having committed it.
