Why do you also transgress? There are here two answers that are given by Christ, the former of which is addressed, as we say, to the person; while the latter decides as to the fact and the question in hand. Mark inverts that order; for he first represents Christ as speaking on the whole subject, and afterwards adds the reproof which is directed against hypocrites. We shall follow the narrative of Matthew. When the Lord, in his turn, puts the question to the scribes why they break the Law of God on account of their traditions, he does not as yet pronounce a direct acquittal of his disciples from the crime charged against them; but only points out how improper and unwarrantable is this readiness to take offense. They are displeased when the commandments of men are not observed with exactness; and how much more criminal is it to spend the whole time in observing them, to the disregard of the law of God? It is manifest, therefore, that their wrath is kindled rather by ambition than by a proper kind of zeal, when they thus prefer men to God. When he says that they transgress the commandments of God, the meaning of the expression is easily learned from the context. They did not openly or professedly set aside the law of God, so as to look upon any thing as lawful which the law had forbidden; but there was an indirect transgression of it, for they permitted duties which God had enjoined to be neglected with impunity. A plain and familiar instance is adduced by Christ. The commandment of God is, that children shall honor their parents, (Exodus 20:12.) Now as the sacred offerings yielded emolument to the priests, the observance of them was so rigidly enforced, that men were taught to regard it as a more heinous sin not to make a free-will offering than to defraud a parent of what was justly due to him. In short, what the Law of God declared to be voluntary was, in the estimation of the scribes, of higher value than one of the most important of the commandments of God. Whenever we are so eager to keep the laws of men as to bestow less care and attention on keeping the law of God itself, we are held as transgressing it. Shortly afterwards he says, that they had annulled the commandment of God on account of the traditions of men; for the scribes led the people to entertain so strong an attachment to their own injunctions, that they did not allow them leisure to attend to the word of God. Again, as they reckoned those persons to have discharged their duty well who obeyed these injunctions to the letter, hence arose a liberty to commit sin; for whenever holiness is made to consist in any thing else than in observing the Law of God, men are led to believe that the law may be violated without danger. Let any man now consider whether this wickedness does not at present abound more among the Papists than it formerly did among the Jews. It is not indeed denied by the Pope, or by the whole of his filthy clergy, that we ought to obey God; but when we come to the point, we find that they consider the act of eating a morsel of flesh as nothing less than a capital crime, while theft or fornication is regarded as a venial fault, and thus, on account of their traditions, they overturn the Law of God; for it is utterly insufferable that the enactments of men shall withdraw any part of that obedience which is due to God alone. Besides, the honor which God commands to be yielded to parents extends to all the duties of filial piety. [1] The latter clause which Christ adds, that he who curseth father or mother deserves to be put to death, is intended to inform us, that it is no light or unimportant precept to honor parents, since the violation of it is so severely punished. And this is no small aggravation of the guilt of the scribes, that so severe a threatening does not terrify them from granting an extension of liberty to those who despised their parents.

1 - "Comprend tous devoirs d'obeissance, secours, et soulagement;" -- "includes every duty of obedience, assistance, and relief."

But he answered - They accused him of violating their traditions, as though they were obligatory.
In his answer he implied that his disciples were not bound to obey their traditions - they were invented by human beings. He said, also, that those traditions could not be binding, as they violated the commandments of God. He proceeded to specify a case in which their tradition made void one of the plain laws of God; and if that was their character, then they could not blame him for not regarding them.

Why do ye - transgress the commandment - Ye accuse my disciples of transgressing the traditions of the elders - I accuse you of transgressing the commands of God, and that too in favor of your own tradition; thus preferring the inventions of men to the positive precepts of God. Pretenders to zeal often prefer superstitious usages to the Divine law, and human inventions to the positive duties of Christianity.

(2) But he answered and said unto them, Why do ye also transgress the commandment of God by your tradition?
(2) Their wicked boldness in corrupting the commandments of God (and that upon the pretence of godliness) and usurping authority to make laws, is reproved here.

But he answered and said unto them,.... Taking no notice of the tradition about eating bread without washing the hands, whether it was right or wrong; it being at most but an human tradition, of no moment and importance, whether it was broke or kept; he makes a very just recrimination, by putting another question to them,
why do you also transgress the commandment of God by your tradition? suggesting, that, if his disciples were guilty, they were not so guilty as they themselves were; that his disciples, at most, were but guilty of the breach of an human precept, whereas they were guilty of the breach of a divine command; and that it was strange, that men who were so scrupulous of breaking, and bore so hard on such as did transgress the traditions of the elders, could allow themselves to transgress the commandments of God; yea, to do this by, and while they were observing their own traditions: and which observation carries a full acquittance of the disciples from blame; for, if by keeping the traditions of the elders, they broke the commands of God, it was a very good reason why they should not observe them.

But he answered and said unto them, Why do ye also transgress the commandment of God by your tradition?--The charge is retorted with startling power: "The tradition they transgress is but man's, and is itself the occasion of heavy transgression, undermining the authority of God's law."

Why do ye also transgress? The Lord does not deny their charge, but strikes at the evil by showing that their human traditions led them to break God's written law.

They wash not their hands when they eat bread - Food in general is termed bread in Hebrew; so that to eat bread is the same as to make a meal.
