Augustine of Hippo
Catena Aurea · Matthäusevangelium 6
But thou, when thou fastest, anoint thine head, and wash thy face; 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.
(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.
