Matthew 15:16

What then saith Peter? He saith not, "What can this be which Thou hast said?" but as though it were full of obscurity, he puts his question. And he saith not, "Why hast thou spoken contrary to the law?" for he was afraid, lest he should be thought to have taken offense, but asserts it to be obscure. However, that it was not obscure, but that he was offended, is manifest, for it had nothing of obscurity. Wherefore also He rebukes him, saying, "Are ye also yet without understanding?" For as to the multitude, they did not perhaps so much as understand the saying; but themselves were the persons offended. Wherefore, whereas at first, as though asking in behalf of the Pharisees, they were desirous to be told; when they heard Him denouncing a great threat, and saying, "Every plant, which my heavenly Father hath not planted, shall be rooted up," and, "They are blind leaders of the blind," they were silenced. But he, always ardent, not even so endures to hold his peace, but saith, "Declare unto us this parable." What then saith Christ? With a sharp rebuke He answers, "Are ye also yet without understanding? Do ye not yet understand?" But these things He said, and reproved them, in order to cast out their prejudice; He stopped not however at this, but adds other things also, saying, "That whatsoever entereth in at the mouth goeth into the belly, and is cast out into the draught; but those things which proceed out of the mouth come forth from the heart, and they defile the man. For out of the heart proceed evil thoughts, murders, adulteries, fornications, thefts, blasphemies, false-witnessings: and these are the things that defile the man: but to eat with unwashen hands defileth not the man." Seest thou how sharply He deals with them, and in the way of rebuke? Then He establishes His saying by our common nature, and with a view to their cure. For when He saith, "It goeth into the belly, and is cast out into the draught," he is still answering according to the low views of the Jews. For He saith, "it abides not, but goes out:" and what if it abode? it would not make one unclean. But not yet were they able to hear this. And one may remark, that because of this the lawgiver allows just so much time, as it may be remaining within one, but when it is gone forth, no longer. For instance, at evening He bids you wash yourself, and so be clean; measuring the time of the digestion, and of the excretion. But the things of the heart, He saith, abide within, and when they are gone forth they defile, and not when abiding only. And first He puts our evil thoughts, a kind of thing which belonged to the Jews; and not as yet doth He make His refutation from the nature of the things, but from the manner of production from the belly and the heart respectively, and from the fact that the one sort remains, the other not; the one entering in from without, and departing again outwards, while the others are bred within, and having gone forth they defile, and then more so, when they are gone forth. Because they were not yet able, as I said, to be told these things with all due strictness. But Mark saith, that "cleansing the meats," He spake this. He did not however express it, nor at all say, "but to eat such and such meats defileth not the man," for neither could they endure to be told it by Him thus distinctly. And accordingly His conclusion was, "But to eat with unwashen hands defileth not the man."

He is reproved by the Lord, because He supposed that to be spoken parabolically, which was indeed spoken plainly. Which teaches us that that hearer is to be blamed who would take dark sayings as clear, or clear sayings as obscure.

The Lord was used to speak in parables, so that Peter when he heard, That which entereth into the mouth defileth not a man, thought it was spoken as a parable, and asked, as it follows; Then answered Peter, and said unto him, Declare unto us this parable. And because he asked this on behalf of the rest, they are all included in the rebuke, But he said, Are ye also yet without understanding?
