That you appear not unto men to fast, but unto your Father who is in secret: and your Father, who sees in secret, shall reward you openly.
All Commentaries on Matthew 6:18 Go To Matthew 6
Augustine of Hippo
AD 430
It is usual, therefore, to ask what He means, when He says: But you, when you fast, anoint your head, and wash your faces, that you appear not unto men to fast. For it would not be right in any one to teach (although we may wash our face according to daily custom) that we ought also to have our heads anointed when we fast. If, then, all admit this to be most unseemly, we must understand this precept with respect to anointing the head and washing the face as referring to the inner man. Hence, to anoint the head refers to joy; to wash the face, on the other hand, refers to purity: and therefore that man anoints his head who rejoices inwardly in his mind and reason. For we rightly understand that as being the head which has the pre-eminence in the soul, and by which it is evident that the other parts of man are ruled and governed. And this is done by him who does not seek his joy from without, so as to draw his delight in a fleshly way from the praises of men. For the flesh, which ought to be subject, is in no way the head of the whole nature of man. No man, indeed, ever yet hated his own flesh, as the apostle says, when giving the precept as to loving one's wife; but the man is the head of the woman, and Christ is the head of the man. Let him, therefore, rejoice inwardly in his fasting in this very circumstance, that by his fasting he so turns away from the pleasure of the world as to be subject to Christ, who according to this precept desires to have the head anointed. For thus also he will wash his face, i.e. cleanse his heart, with which he shall see God, no veil being interposed on account of the infirmity contracted from squalor; but being firm and steadfast, inasmuch as he is pure and guileless. Wash you, says He, make you clean; put away the evil of your doings from before my eyes. From the squalor, therefore, by which the eye of God is offended, our face is to be washed. For we, with open face beholding as in a glass the glory of the Lord, are changed into the same image.
Often also the thought of things necessary belonging to this life wounds and defiles our inner eye; and frequently it makes the heart double, so that in regard to those things in which we seem to act rightly with our fellowmen, we do not act with that heart wherewith the Lord enjoins us; i.e., it is not because we love them, but because we wish to obtain some advantage from them for the necessity of the present life. But we ought to do them good for their eternal salvation, not for our own temporal advantage. May God, therefore, incline our heart to His testimonies, and not to covetousness. For the end of the commandment is charity out of a pure heart, and of a good conscience, and of faith unfeigned. But he who looks after his brother from a regard to his own necessities in this life, does not certainly do so from love, because he does not look after him whom he ought to love as himself, but after himself; or rather not even after himself, seeing that in this way he makes his own heart double, by which he is hindered from seeing God, in the vision of whom alone there is certain and lasting blessedness.
