name of God is to be held sacred. In sum, therefore, it means, that we
on the divine procedure, that his blessing rests on the posterity of the righteous, and his curse on the posterity of the wicked, much more must it rest on the heads of the individuals themselves. Notwithstanding of this, however, the offspring of the wicked sometimes amends, while that of believers degenerates; because the Almighty has not here laid down an inflexible rule which might derogate from his free election. For the consolation of the righteous, and the dismay of the sinner, it is enough that the threatening itself is not vain or nugatory, although it does not always take effect. For, as the temporal punishments inflicted on a few of the wicked are proofs of the divine wrath against sin, and of the future judgment that will ultimately overtake all sinners, though many escape with impunity even to the end of their lives, so, when the Lord gives one example of blessing a son for his father's sake, by visiting him in mercy and kindness, it is a proof of constant and unfailing favour to his worshipers. On the other hand, when, in any single instance, he visits the iniquity of the father on the son, he gives intimation of the judgment which awaits all the reprobate for their own iniquities. The certainty of this is the principal thing here taught. Moreover, the Lord, as it were by the way, commends the riches of his mercy by extending it to thousands, while he limits his vengeance to four generations.
Third Commandment.
THOU SHALT NOT TAKE THE NAME OF THE LORD THY GOD IN VAIN.
22. The purport of this Commandment is, that the majesty of the name of God is to be held sacred. In sum, therefore, it means, that we must not profane it by using it irreverently or contemptuously. This prohibition implies a corresponding precept—viz. that it be our study and care to treat his name with religious veneration. Wherefore it becomes us to regulate our minds and our tongues, so as never to think or speak of God and his mysteries without reverence and great soberness, and never, in estimating his works, to have any feeling towards him but one of deep veneration. We must, I say, steadily observe the three following things:—First, Whatever our mind conceives of him, whatever our tongue utters, must bespeak his excellence, and correspond to the sublimity of his sacred name; in short, must be fitted to extol its greatness. Secondly, We must not rashly and preposterously pervert his sacred word and adorable mysteries to purposes of ambition, or avarice, or amusement, but, according as they bear the impress of his dignity, must always maintain them in due honour and esteem. Lastly, We must not detract from or throw obloquy upon his works, as miserable men are wont insultingly to do, but must laud every action which we attribute to him as wise, and just, and good. This is to sanctify the name of God. When we act otherwise, his name is profaned with vain and wicked abuse, because it is applied to a purpose foreign to that to which it is consecrated. Were there nothing worse, in being deprived of its dignity it is gradually brought into contempt. But if there is so much evil in the rash and unseasonable employment of the divine name, there is still more evil in its being employed for nefarious purposes, as is done by those who use it in necromancy, cursing, illicit exorcisms, and other impious incantations. But the Commandment refers especially to the case of oaths, in which a perverse employment of the divine name is particularly detestable; and this it does the more effectually to deter us from every species of profanation. That the thing here commanded relates to the worship of God, and the reverence due to his name, and not to the equity which men are to cultivate towards each other, is apparent from this, that afterwards, in the Second Table, there is a condemnation of the perjury and false testimony by which human society is injured, and that the repetition would be superfluous, if, in this Commandment, the duty of charity were handled. Moreover, this is necessary even for distinction, because, as was observed, God has, for good reason, divided his Law into two tables. The inference then is, that God here vindicates his own right, and defends his sacred name, but does not teach the duties which men owe to men.
