33. Offspring of vipers. After having demonstrated that the scribes are not only base enemies of sound doctrine, and wicked corrupters of the worship of God, but likewise deadly plagues of the Church, Christ, being about to close his discourse, kindles into more vehement indignation against them; as it is necessary to shake off by violence the flatteries in which hypocrites indulge, and to drag them, as it were, to the judgment seat of God, that they may be filled with alarm. And yet Christ did not keep them alone in his eye, but intended to strike terror into the whole people, that all might guard against a similar destruction. How harsh and intolerable this roughness of language must have been to these reverend instructors may easily be inferred from the long period during which they had held a peaceful dominion, so that no one dared to mutter against them. And there can be no doubt that many were displeased with the great freedom and sharpness which Christ used, and, above all, that he was looked upon as immoderate and outrageous in venturing to apply such reproachful epithets to the order of the scribes; as many fastidious persons of the present day cannot endure any harsh word to be spoken against the Popish clergy. But as Christ had to deal with the worst of hypocrites, who not only were swelled with proud contempt of God, and intoxicated with careless security, but had captivated the multitude by their enchantments, he found it necessary to exclaim against them with vehemence. He calls them serpents both in nature and in habits, and then threatens them with a punishment, which it will be in vain for them to attempt to escape, if they do not speedily repent.
