(15) Declare unto us this parable.--The answer shows that Peter's question referred not to the proverb that immediately preceded, but to what seemed to him the strange, startling utterance of Matthew 15:11. It was significant that he could not as yet take in the thought that it was a truth to be received literally. To him it seemed a dark enigmatic saying, which required an explanation, like that which had been given of the parable of the Sower, to make its meaning clear.
Verse 15. - Then answered Peter. The disciples could not understand the apparent depreciation of the external in religion; they did not see the meaning of what Christ had said. Peter, as their mouthpiece, asked for further explanation. Declare; φράσον: edissere. Explain. Parable. The word in an extended sense is used of any hard, enigmatical saying or figurative expression. The term here is applied to the statement in ver. 11. The apostles did not comprehend the minimizing of the rules concerning purification, and the possibility of a man being defiled by what proceeded from his mouth. Inveterate prejudices die hard, and it is difficult to emancipate one's self from old modes of thought.
15:10-20 Christ shows that the defilement they ought to fear, was not from what entered their mouths as food, but from what came out of their mouths, which showed the wickedness of their hearts. Nothing will last in the soul but the regenerating graces of the Holy Spirit; and nothing should be admitted into the church but what is from above; therefore, whoever is offended by a plain, seasonable declaration of the truth, we should not be troubled at it. The disciples ask to be better taught as to this matter. Where a weak head doubts concerning any word of Christ, an upright heart and a willing mind seek for instruction. It is the heart that is desperately wicked, Jer 17:9, for there is no sin in word or deed, which was not first in the heart. They all come out of the man, and are fruits of that wickedness which is in the heart, and is wrought there. When Christ teaches, he will show men the deceitfulness and wickedness of their own hearts; he will teach them to humble themselves, and to seek to be cleansed in the Fountain opened for sin and uncleanness.
Then answered Peter,.... Mark says, "his disciples asked him concerning the parable"; which might be by the mouth of Peter; who, probably, being the eldest man, and very forward to speak, was generally their spokesman: and who, at this time, might be requested, by the rest, to ask the meaning of the parable, which had given offence to the Pharisees, and was not clearly understood by them; which he accordingly did:
and said unto him, declare unto us this parable; that not what goes into the mouth, but what comes out of it, defiles the man; which, though expressed in very plain words, and easy to be understood, yet did not appear clear to their understandings; and seemed to be contrary, not only to the traditions of the elders, but to the laws of God, respecting the difference of clean and unclean meats; and therefore call it a "parable", and desire an explanation of it.
