33. Either make the tree good, and its fruit good: or make the tree bad, and its fruit bad; for the tree is known by the fruit. 34. Offspring of vipers, how can you speak what is good, when you are bad? for out of the abundance of the heart the mouth speaketh. 35. A good man, out of the good treasure of his heart, bringeth forth what is good, and a bad man, out of the bad treasure, bringeth forth what is evil. 36. But I say to you, That men will give account, at the day of judgment, for every idle word which they shall have spoken. 37. For by thy words thou shalt be justified, and by thy words thou shalt be condemned.
33. Either make the tree good It might look like absurdity, that men should be allowed a choice of being either good or bad; but if we consider what sort of persons Christ is addressing, the difficulty will be speedily resolved. We know what opinion was generally entertained about the Pharisees; for their pretended sanctity had so blinded the minds of the common people, that no one ventured to pass sentence on their vices. 1 Wishing to remove this mask, Christ desires them to be either good or bad; or, in other words, declares that nothing is more inconsistent with honesty than hypocrisy, and that it is in vain for men to boast of pretensions to righteousness who are not sincere and upright. 2 So then he puts nothing at their disposal, and withdraws no restraint from them, but only reminds them that their empty professions will avail them nothing so long as they are double, because they must be either good or bad
From the expression, make the tree, some foolishly infer, that it is in every man’s power to regulate his own life and conduct. It is a rhetorical mode of speaking, by which Christ points out the scribes, dispels—so to speak—the smoke of their hypocrisy, and recalls them to pure and genuine uprightness. He afterwards explains the way and manner in which they may show that they are good or bad trees; which is by yielding good or bad fruit: so that there is no ambiguity in the meaning. The life of the scribes was not rendered infamous among men by gross vices. Pride, ambition, and envy, displayed their venom in the slanders which they uttered; but as that venom was not perceived by ignorant people, Christ brings the concealed evil from its lurking-place, and drags it forth to light.
But perhaps it will be objected that, in consequence of the corruption of our nature, it is impossible to find any man who is altogether upright, and free from every vice. The answer is ready. Christ does not demand absolute and entire perfection, but only a sincere and unfeigned disposition, which the Pharisees whom he addresses were far from possessing. As Scripture applies the terms, bad and wicked, to those who are completely given up to Satan, so the sincere worshippers of God, though they are encompassed by the infirmity of their flesh and by many sins, and groan under the burden, are called good. This arises from the undeserved kindness of God, who bestows so honorable a designation on those who aim at goodness.
34. Offspring of vipers. The similarity between the tree and the fruit is here applied by Christ to nothing more than speech, because this afforded an opportunity of detecting the inward and concealed malice of the scribes; and that is the reason why he dwells so much on this one kind of sin. It is because their falsehood and slanders betrayed what was not so visible in the rest of their life, that Christ attacks them with such severity. “There is no reason to wonder,” he says, “that you vomit out wicked words; for your heart is full of malice.” Nor are we to suppose that he ought to have treated them with greater gentleness, because some might regard this reproof as excessively severe. There are other sins, no doubt, that call for harsh reproofs; but when hypocritical persons pervert what is right, or put a false coloring on what is sinful, such wickedness renders it necessary that God should thunder against it in a more terrible manner than against other sins.
Now the design of Christ, suggested by the present occurrence, was to condemn the wicked sophistry which turns light into darkness. This passage shows how highly valuable in the sight of the Lord truth is, since he maintains and defends it with such rigor. Would that this were earnestly considered by those persons, whose ingenuity is too ready to be employed in defending any cause, and whose venal tongue disguises impostures! In a particular manner, Christ waxes wroth against those whom ambition, or envy, or some other fraudulent design, prompts to slander, even when there is nothing that their conscience condemns. Against the Pharisees, too, as his custom was, Christ used greater harshness, because they were so captivated by an unfounded conviction of their righteousness, that an ordinary warning had no effect upon them. And till hypocrites are sharply pierced, 3 all that is said to them is treated with scorn and contempt.
