Thou shalt not take the name of the Lord thy God in vain.
XXII. The end of this precept is, that the Lord will have the majesty of his name to be held inviolably sacred by us. The substance of the command therefore is, that we ought not to profane that name by a contemptuous or irreverent use of it. This prohibition necessarily implies an injunction, that we studiously and carefully treat it with religious veneration. Therefore it becomes us to regulate our thoughts and words in such a manner that we may not think or speak any thing concerning God and his mysteries, but with the greatest sobriety and reverence; that in meditating on his works we may form no opinion that is dishonourable to him. These three things, I say, we ought most carefully to observe—first, that whatever we think, and whatever we say of him, should savour of his excellence, correspond to the sacred sublimity of his name, and tend to the exaltation of his magnificence. Secondly, we should not rashly and preposterously abuse his holy word and adorable mysteries to the purposes of ambition, of avarice, or of amusement; but as they bear an impression of the dignity of his name, they should always receive from us the honour and esteem which belong to them. Lastly, we should not injure his works by obloquy or detraction, as some miserable mortals are accustomed to do; but whenever we mention any thing done by him, we should celebrate it with encomiums of wisdom, justice, and goodness. This is “sanctifying” the name of God. In every other case, it is violated by a vain and criminal abuse, because it is carried beyond the limits of that legitimate use, to which alone it is consecrated; and though no other consequence ensue, it is deprived of its dignity, and by degrees rendered contemptible. But if it be so criminal thus rashly and unseasonably to introduce the name of God on every occasion, much more so must it be to apply it to such nefarious uses as they do, who make it subservient to the superstitions of necromancy, to horrible imprecations, to unlawful exorcisms, and to other impious incantations. But an oath is the thing principally contemplated in the command, as the most detestable instance of the perverse abuse of the Divine name; and this is done to inspire us with the greater horror of every species of profanation of it. That this precept relates to the worship of God and the reverence of his name, and not to the equity that ought to be observed among mankind, appears from this—that the subsequent condemnation, in the second table, of perjury and false witness, by which society is injured, would be a needless repetition, if the present precept related to a civil duty. Besides, the division of the law requires this; for, as we have already observed, it is not in vain that God has distributed the law into two tables. Whence we conclude, that in this command he vindicates his just claims, and guards the sanctity of his name, but does not teach the duties which men owe to each other.
