Augustine of Hippo, on Matt 6:16

“And when you fast, be not as the hypocrites, sad. For they disfigure their faces, that they may appear unto men to fast. Amen I say to you, they have received their reward.”

“(Serm. in Mont. ii. 12.) On this paragraph it is to be specially noted, that not only in outward splendor and pomp, but even in the dress of sorrow and mourning, is there room for display, and that the more dangerous, inasmuch as it deceives under the name of God’s services. For he who by inordinate pains taken with his person, or his apparel, or by the glitter of his other equipage, is distinguished, is easily proved by these very circumstances to be a follower of the pomps of this world, and no man is deceived by any semblance of a feigned sanctity in him. But when any one in the profession of Christianity draws men’s eyes upon him by unwonted beggary and slovenliness in dress, if this be voluntary and not compulsory, then by his other conduct may be seen whether he does this to be seen of men, or from contempt of the refinements of dress.”
