Commentary on a Harmony of the Evangelists Matthew Mark and Luke John Calvin
JOHN CALVIN
and accessory. It may readily be believed that this dream proceeded from the scribes and priests, because it was a scheme well fitted for collecting prey. And this was not only a foolish but a highly dangerous error, because it led the people into ridiculous fancies. There is nothing to which men are more prone than to fall away from the pure worship of God: and therefore, under the covering of this veil, it was easy for Satan to withdraw from the contemplation of God those who were too strongly inclined to foolish imaginations. This is the reason why Christ so severely chastises that error. And yet the Papists were not ashamed to prostitute the sacred name of God to a mockery still more detestable; for they reckon it of more importance to touch a morsel of a stinking carcass, than to peruse the sacred volume of the Old and New Testaments, or even to raise their hands towards heaven. And in this way arises a carnal worship of God, by which the proper fear of God is gradually obliterated.
It is nothing. By this phrase he does not mean that they entirely took away the honor of the temple, but he speaks comparatively. For when they represented in extravagant terms the sacredness of offerings, the common people were led to entertain such veneration for them, that the majesty of the temple and of the altar was undervalued, and they reckoned it a less heinous crime to violate it by perjuries than to swear by the sacred offerings with too little reverence.
18. And whosoever shall swear by the altar. Here our Lord does what ought to be done in correcting errors; for he leads us up to the source, and shows, by the very nature of an oath, that the temple is far more valuable than the gifts which are offered in it. He accordingly assumes this principle, that it is not lawful to swear but by the name of God alone. Hence it follows that, whatever forms men may employ in swearing, they must give to God the honor which is due to him; and hence also it follows in what manner and to what extent we are at liberty to swear by the temple, namely, because it is the residence or sanctuary of God; and by heaven, because there the glory of God shines. God permits himself to be called as a witness and judge, by means of such symbols of his presence, provided that he retain his authority unimpaired; for to ascribe any Divinity to heaven would be detestable idolatry.
Now so far as God holds out to us a brighter mirror of his glory in the temple than in offerings, so much the greater reverence and sacredness is due to the name of the temple. We now perceive, therefore, in what sense Christ says that we swear by him who inhabits heaven, when we swear by heaven itself. His design is, to direct all forms of swearing to their lawful end and object.
