Matthew 6:17,18

Ver 17. "But thou, when thou fastest, anoint thine head, and wash thy face; 18. That thou appear not unto men to fast, but unto thy Father which is in secret: and thy Father, which seeth in secret, shall reward thee openly."

Gloss. 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."

Aug.: 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 anointed when we fast; a thing which all allow to be most disgraceful.

Pseudo-Chrys.: Also if He bade us not to be of sad countenance that we might not seem to men to fast, yet if anointing of the head and washing of the face are always observed in fasting, they will become tokens of fasting.

Jerome: But He speaks in accordance with the manner of the province of Palestine, where it is the custom on festival days to anoint the head. What He enjoins then is, that when we are fasting we should wear the appearance of joy and gladness.

Pseudo-Chrys.: Therefore the simple interpretation of this is, that is added as an hyperbolical explanation of the command; as though He had said, Yea, so far should ye be from any display of your fasting, that if it might be (which yet it may not be) so done, ye should even do such things as are tokens of luxury and feasting.

Chrys., Hom. xx: In almsgiving indeed, He did not say simply, 'Do not your alms before men,' but added, 'to be seen of them.' But in fasting and prayer He added nothing of this sort; because alms cannot be so done as to be altogether hid, fasting and prayer can be so done. The contempt of men's praise is no small fruit, for thereby we are freed from the heavy slavery of human opinions, and become properly workers of virtue, loving it for itself and not for others. For as we esteem it an affront if we are loved not for ourselves but for others' sake, so ought we not to follow virtue on the account of these men, nor to obey God for men's sake but for His own.

Therefore it follows here, "But to thy Father which seeth in secret."

Gloss.: That is, to thy heavenly Father, who is unseen, or who dwells in the heart through faith. He fasts to God who afflicts himself for the love of God, and bestows on others what he denies himself.

Remig.: For it is enough for you that He who sees your conscience should be your rewarder.

Pseudo-Chrys.: Spiritually interpreted - the face may be understood to mean the mental conscience. And as in the eyes of man a fair face has grace, so in the eyes of God a pure conscience has favour. This face the hypocrites, fasting on man's account, disfigure, seeking thereby to cheat both God and man; for the conscience of the sinner is always wounded. If then you have cast out all wickedness from your heart, you have washed your conscience, and fast well.

Leo, Serm. in Quadr., vi, 2: Fasting ought to be fulfilled not in abstinence of food only, but much more in cutting off vices. For when we submit ourselves to that discipline in order to withdraw that which is the nurse of carnal desires, there is no sort of good conscience more to be sought than that we should keep ourselves sober from unjust will, and abstinent from dishonourable action. This is an act of religion from which the sick are not excluded, seeing integrity of heart may be found in an infirm body.

Pseudo-Chrys.: Spiritually again, "thy head" denotes Christ. Give the thirsty drink and feed the hungry, and therein you have anointed your head, that is, Christ, who cries out in the Gospel, "In that ye have done this to one of the least of these my brethren, ye have done it to me." [Matthew 25:40]

Greg., 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.

Aug.: 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.

Gloss. 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.

Pseudo-Chrys.: And truly we ought to wash our face, but to anoint, and not to wash, our head. For as long as we are in the body, our conscience is foul with sin. But Christ who is our head has done no sin.
