The Third Commandment

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.

XXIII. In the first place, we have to explain what an oath is. It consists in calling upon God as a witness, to confirm the truth of any declaration that we make. For execrations, which contain manifest reproaches against God, are not worthy to be mentioned among oaths. That such an attestation, when rightly performed, is a species of Divine worship, is evident from many places of Scripture; as when Isaiah prophesies of the vocation of the Assyrians and Egyptians to participate in the covenant with Israel. “They shall speak,” says he, “the language of Canaan, and swear to the Lord of hosts.”⁸⁴³ By “swearing to the Lord” here is intended making a profession of religion. Again, when he speaks of the extension of his kingdom: “He who blesseth himself in the earth shall bless himself in the God of truth; and he that sweareth in the earth shall swear by the God of truth.”⁸⁴⁴ Jeremiah says, “If they will diligently learn the ways of my people, to swear by my name, The Lord liveth; as they taught my people to swear by Baal, then shall they be built in the midst of my people.”⁸⁴⁵ And we are justly said to profess our religion to the Lord, when we invoke his name to bear witness to us. For thereby we confess that he is truth itself, eternal and immutable; whom we call not only as a witness of the truth, excelling all others, but also as the only defender of it, who is able to bring to light things which are concealed, and in a word, as the searcher of all hearts. For where human testimonies are wanting, we resort for refuge to the testimony of God; and particularly when any thing is to be affirmed, which is hidden in the conscience. For which reason the Lord is extremely angry with them who swear by strange gods, and interprets that species of swearing as a proof of manifest defection from him. “Thy children have forsaken me, and sworn by them that are no gods.”⁸⁴⁶ And he declares the atrociousness of this crime by his denunciation of punishment: “I will cut off them that swear by the Lord, and that swear by Malcham.”⁸⁴⁷

XXIV. Now, since we understand it to be the will of the Lord, that we should reverence his name in our oaths, we ought to use so much the more caution, lest, instead of reverence, they betray dishonour or contempt of it. It is no trifling insult to him, when perjury is committed in his name; and therefore the law calls it a profanation.⁸⁴⁸ But what remains to the Lord, when he is despoiled of his truth? he will then cease to be God. But he is certainly despoiled of it, when he is made an abettor and approver of a falsehood. Wherefore, when Joshua would induce Achan to a confession of the truth, he says, “My son, give, I pray thee, glory to the Lord God of Israel;”⁸⁴⁹ implying in this that the Lord is grievously dishonoured, if perjury be committed in his name. Nor is this strange; for in such a case we do all that is in our power to brand his sacred name with a falsehood. And that this form of expression was customary among the Jews, whenever any man was called to take an oath, appears from a similar adjuration used by the Pharisees in the Gospel of John.⁸⁵⁰ To this caution we are accustomed by the forms of oaths which are used in the Scriptures: “The Lord liveth;”⁸⁵¹ “God do so and more also to me;”⁸⁵² “I call God for a record upon my soul;”⁸⁵³ which imply, that we cannot invoke God to be a witness to our declarations, without imprecating his vengeance upon us if we be guilty of perjury.

XXV. The name of God is rendered vile and contemptible, when it is used in unnecessarily swearing even to what is true; for in this instance also it is taken in vain. Wherefore it will not be sufficient to abstain from perjury; unless we also remember, that swearing is permitted and appointed, not for the sake of our pleasure or caprice, but from necessity; and that the lawful use of it, therefore, is transgressed by those who apply it to cases where it is not necessary. Now, no other necessity can be pretended, but when we want to serve either religion or charity. This crime, in the present day, is carried to a very great extent; and it is so much the more intolerable, since by its frequency it has ceased to be considered as a crime, though before the Divine tribunal it is deemed no trivial offence. For the name of God is universally profaned without concern in trifling conversations; and it is not considered as sinful, because this presumptuous wickedness has been so long practised with impunity. But the Divine command remains valid; the sanction remains firm; and a future day will witness the completion of that part of it which denounces a particular punishment against those who take his name in vain. This precept is violated also in another way. If in our oaths we substitute the servants of God in the place of God himself, we are guilty of manifest impiety; because we thereby transfer to them the glory due to the Deity. Nor is it without reason, that God, by a special command, enjoins us to swear by his name,⁸⁵⁴ and by a special prohibition interdicts us from swearing by any strange gods.⁸⁵⁵ And the Apostle evidently attests the same, when he says, that “men swear by the greater, but that God, because he could swear by no greater, sware by himself.”⁸⁵⁶

XXVI. The Anabaptists, not satisfied with this limitation of oaths, condemn all oaths without exception; because the prohibition of Christ is general: “I say unto you, Swear not at all. But let your communication be, Yea, yea; Nay, nay: for whatsoever is more than these cometh of evil.”⁸⁵⁷ But by this mode of interpretation they set Christ in opposition to the Father, as though he descended into this world to abrogate the Father's decrees. For in the law the eternal God not only permits an oath, as a lawful thing, which would be sufficient to justify the use of it, but in cases of necessity commands it.⁸⁵⁸ Now, Christ asserts, that “he and his Father are one,” that “he acts only according to the commands of the Father,” that “his doctrine is not of himself,” &c.⁸⁵⁹ What then? Will they make God to contradict himself, by prohibiting and condemning in our conduct that which he has before approved and enjoined? But as the words of Christ involve some difficulty, let us enter on a brief examination of them. Here we shall never arrive at the truth, unless we attend to the design of Christ, and advert to the subject of which he is there treating. His design is not to relax or to restrict the law, but to reduce it to its true and genuine meaning, which had been very much corrupted by the false comments of the scribes and Pharisees. If we bear this in our minds, we shall not be of opinion that Christ condemned all oaths, but only those which transgress the rule of the law. It appears to have been the custom of the people at that time to avoid nothing but perjuries; whereas the law forbids not only perjuries, but likewise all vain and superfluous oaths. Our Lord, therefore, that infallible expositor of the law, apprizes them that it is sinful, not only to perjure themselves, but even to swear. To swear in what manner? In vain. But the oaths which are sanctioned in the law he leaves without any objection. They consider themselves as urging a very powerful argument, when they violently insist on the particle at all; which, nevertheless, refers not to the word swear, but to the forms of oaths that are there subjoined. For the error there condemned consisted, partly, in a supposition that in swearing by heaven and earth, there was no interference with the name of God. Therefore, after the principal instance of transgression, the Lord goes on to destroy all their subterfuges, that they may not imagine themselves to have escaped by suppressing the name of God, and calling heaven and earth to witness for them. For here, by the way, it must be remarked, that men indirectly swear by God, though his name is not expressed; as when they swear by the light of life, by the bread which they eat, by their baptism, or by any other blessings which they have received from the Divine munificence. Nor does Christ in that place prohibit them from swearing by heaven, and earth, and Jerusalem, in order to correct superstition, as some falsely imagine; but rather to confute the sophistical subtlety of persons who thought there was no crime in the foolish use of indirect oaths, as though they were not chargeable with profaning the sacred name of God, which is engraven, however, on all his benefits. But the case is different, where any mortal man, or one that is dead, or an angel, is substituted in the place of God; as, among idolatrous nations, adulation invented that odious form of swearing by the life or genius of a king; because in such cases the deification of a creature obscures and diminishes the glory of the only true God. But when we mean nothing but to derive a confirmation to our assertions from the sacred name of God, although it be done in an indirect manner, yet all such frivolous oaths are offensive to his majesty. Christ deprives this licentious practice of every vain excuse, by his prohibition of swearing at all. James also aims at the same point,⁸⁶⁰ where he uses the language of Christ, which I have cited; because this presumption has always been prevalent in the world, notwithstanding it is a profanation of the name of God. For if you refer the particle at all to the substance of swearing, as though every oath, without exception, were unlawful, what means the explanation which is immediately annexed, “Neither by heaven, neither by earth,” &c., language evidently used in refutation of those cavils, which the Jews considered as furnishing an excuse for their sin.

XXVII. It can no longer be doubtful, therefore, to persons of sound judgment, that the Lord, in that passage, only condemns those oaths which had been forbidden by the law. For even he, who exhibited in his life an example of the perfection which he inculcated, hesitated not to make use of oaths whenever occasion required; and his disciples, who, we doubt not, were obedient to their master in all things, followed the same example. Who can dare to assert, that Paul would have sworn, if all oaths had been prohibited? But when the occasion requires it, he swears without any scruple, and sometimes even adds an imprecation. The question, however, is not yet decided; for it is the opinion of some persons, that public oaths are the only exceptions from this prohibition; such as we take when required by a magistrate; such also as princes are accustomed to use in ratifying treaties; or subjects, when they swear allegiance to their princes; or soldiers, as a military test; and others of a similar kind. To this class also they justly refer those oaths which we find used by Paul in assertion of the dignity of the gospel; because the Apostles, in the exercise of their functions, were not private persons, but public ministers of God. And indeed I will not deny that these are the safest oaths; because they are sanctioned by the strongest testimonies of Scripture. A magistrate is directed, in a dubious case, to put a witness to his oath, and the witness, on the other hand, is required to answer on his oath; and the Apostle says, that human controversies are adjusted by this expedient.⁸⁶¹ In this precept both parties are furnished with a complete justification of their conduct. Moreover we may observe, that among the ancient heathen a public and solemn oath was held in great reverence; but that common ones, which they used in their ordinary intercourse, were not esteemed of any, or of much importance, because they imagined that these were not regarded by the Divine majesty. But it would be too dangerous to condemn private oaths, which are taken, in cases of necessity, with sobriety, integrity, and reverence, since they are supported both by reason and by scriptural examples. For if it be lawful for private persons in an important and serious affair to appeal to God as a judge between them, much more must it be allowable to invoke him as a witness. Your brother will accuse you of perfidy; you endeavour to exculpate yourself; he will not permit himself by any means to be satisfied. If your reputation be endangered by his obstinate malignity, you may, without any offence, appeal to the judgment of God, that in his own time he will manifest your innocence. If the words be strictly examined, it is a less thing to appeal to him as a witness than as a judge. I see not, therefore, why we should assert such an appeal to him to be unlawful. There are not wanting numerous examples of it. If the oath of Abraham and Isaac with Abimelech be alleged to have been taken in a public capacity, certainly Jacob and Laban were private persons, and yet they confirmed the covenant between them by a mutual oath.⁸⁶² Boaz was a private person, who confirmed in the same manner his promise of marriage to Ruth.⁸⁶³ Obadiah was a private person, a righteous man, and one that feared the Lord, who declared with an oath the fact of which he wished to convince Elijah.⁸⁶⁴ I can find, therefore, no better rule, than that we regulate our oaths in such a manner, that they be not rash or inconsiderate, wanton or frivolous, but used in cases of real necessity, as for vindicating the glory of the Lord, or promoting the edification of our brother; which is the end of this commandment of the law.

The Fourth Commandment

Remember the sabbath day, to keep it holy. Six days shalt thou labour, and do all thy work; but the seventh day is the sabbath of the Lord thy God; in it thou shalt not do any work, &c.

XXVIII. The end of this precept is, that, being dead to our own affections and works, we should meditate on the kingdom of God, and be exercised in that meditation in the observance of his institutions. But, as it has an aspect peculiar and distinct from the others, it requires a little different kind of exposition. The fathers frequently call it a shadowy commandment, because it contains the external observance of the day, which was abolished with the rest of the figures at the advent of Christ. And there is much truth in their observation; but it reaches only half of the subject. Wherefore it is necessary to seek further for an exposition, and to consider three causes, on which I think I have observed this commandment to rest. For it was the design of the heavenly Lawgiver, under the rest of the seventh day, to give the people of Israel a figure of the spiritual rest, by which the faithful ought to refrain from their own works, in order to leave God to work within them. His design was, secondly, that there should be a stated day, on which they might assemble together to hear the law and perform the ceremonies, or at least which they might especially devote to meditations on his works; that by this recollection they might be led to the exercises of piety. Thirdly, he thought it right that servants, and persons living under the jurisdiction of others, should be indulged with a day of rest, that they might enjoy some remission from their labour.

XXIX. Yet we are taught in many places that this adumbration of the spiritual rest was the principal design of the sabbath. For the Lord is hardly so strict in his requisitions of obedience to any other precept.⁸⁶⁵ When he means to intimate, in the Prophets, that religion is totally subverted, he complains that his sabbaths are polluted, violated, neglected, and profaned;⁸⁶⁶ as though, in case of that duty being neglected, there remained no other way in which he could be honoured. On the other hand, he notices the observance of it with singular encomiums. Wherefore also, among the other Divine communications, the faithful used very highly to esteem the revelation of the sabbath. For this is the language of the Levites in a solemn assembly, recorded by Nehemiah: “Thou madest known unto our fathers thy holy sabbath, and commandedst them precepts, statutes, and laws, by the hand of Moses.”⁸⁶⁷ We see the singular estimation in which it is held above all the commandments of the law. All these things tend to display the dignity of the mystery, which is beautifully expressed by Moses and Ezekiel. In Exodus we read as follows: “Verily my sabbaths ye shall keep; for it is a sign between me and you throughout your generations; that ye may know that I am the Lord that doth sanctify you. Ye shall keep the sabbath therefore; for it is holy unto you. The children of Israel shall keep the sabbath, to observe the sabbath throughout their generations, for a perpetual covenant. It is a sign between me and the children of Israel for ever.”⁸⁶⁸ This is more fully expressed by Ezekiel; but the substance of what he says is, that the sabbath was a sign by which the Israelites might know that God was their sanctifier.⁸⁶⁹ If our sanctification consists properly in the mortification of our own will, there is a very natural analogy between the external sign and the internal thing which it represents. We must rest altogether, that God may operate within us; we must recede from our own will, resign our own heart, and renounce all our carnal affections; in short, we must cease from all the efforts of our own understanding, that having God operating within us, we may enjoy rest in him, as we are also taught by the Apostle.⁸⁷⁰

XXX. This perpetual cessation was represented to the Jews by the observance of one day in seven, which the Lord, in order that it might be the more religiously kept, recommended by his own example. For it is no small stimulus to any action, for a man to know that he is imitating his Creator. If any one inquire after a hidden signification in the septenary number, it is probable, that because in Scripture it is the number of perfection, it is here selected to denote perpetual duration. This is confirmed also by the circumstance, that Moses, with that day in which he narrates that the Lord rested from his works, concludes his description of the succession of days and nights. We may also adduce another probable conjecture respecting this number – that the Lord intended to signify that the sabbath would never be completed until the arrival of the last day. For in it we begin that blessed rest, in which we make new advances from day to day. But because we are still engaged in a perpetual warfare with the flesh, it will not be consummated before the completion of that prediction of Isaiah, “It shall come to pass, that from one new moon to another, and from one sabbath to another, shall all flesh come to worship before me, saith the Lord;”⁸⁷¹ that is, when God shall be “all in all.”⁸⁷² The Lord may be considered, therefore, as having delineated to his people, in the seventh day, the future perfection of his sabbath in the last day, that, by a continual meditation on the sabbath during their whole life, they might be aspiring towards this perfection.

XXXI. If any one disapprove of this observation on the number, as too curious, I object not to its being understood in a more simple manner; that the Lord ordained a certain day, that the people under the discipline of the law might be exercised in continual meditations on the spiritual rest; that he appointed the seventh day, either because he foresaw it would be sufficient, or in order that the proposal of a resemblance to his own example might operate as a stronger stimulus to the people, or at least to apprize them that the only end of the sabbath was to promote their conformity to their Creator. For this is of little importance, provided we retain the mystery, which is principally exhibited, of a perpetual rest from our own works. To the contemplation of this, the Prophets used frequently to recall the Jews, that they might not suppose themselves to have discharged their duty merely by a cessation from manual labours. Beside the passages already cited, we have the following in Isaiah: “If thou turn away thy foot from the sabbath, from doing thy pleasure on my holy day; and call the sabbath a delight, the holy of the Lord, honourable; and shalt honour him, not doing thine own ways, nor finding thine own pleasure, nor speaking thine own words; then shalt thou delight thyself in the Lord,” &c.⁸⁷³ But all that it contained of a ceremonial nature was without doubt abolished by the advent of the Lord Christ. For he is the truth, at whose presence all figures disappear; the body, at the sight of which all the shadows are relinquished. He, I say, is the true fulfilment of the sabbath. Having been “buried with him by baptism, we have been planted together in the likeness of his death, that being partakers of his resurrection, we may walk in newness of life.”⁸⁷⁴ Therefore the Apostle says in another place, that “the sabbath was a shadow of things to come; but the body is of Christ;”⁸⁷⁵ that is, the real substance of the truth, which he has beautifully explained in that passage. This is contained not in one day, but in the whole course of our life, till, being wholly dead to ourselves, we be filled with the life of God. Christians therefore ought to depart from all superstitious observance of days.

XXXII. As the two latter causes, however, ought not to be numbered among the ancient shadows, but are equally suitable to all ages, – though the sabbath is abrogated, yet it is still customary among us to assemble on stated days for hearing the word, for breaking the mystic bread, and for public prayers; and also to allow servants and labourers a remission from their labour. That in commanding the sabbath, the Lord had regard to both these things, cannot be doubted. The first is abundantly confirmed even by the practice of the Jews. The second is proved by Moses, in Deuteronomy, in these words: “that thy man-servant and thy maid-servant may rest as well as thou. And remember that thou wast a servant in the land of Egypt.”⁸⁷⁶ Also, in Exodus: “that thine ox and thine ass may rest, and the son of thy handmaid, and the stranger, may be refreshed.”⁸⁷⁷ Who can deny that both these things are as proper for us as for the Jews? Assemblies of the Church are enjoined in the Divine word, and the necessity of them is sufficiently known even from the experience of life. Unless there be stated days appointed for them, how can they be held? According to the direction of the Apostle, “all things” are to “be done decently and in order” among us.⁸⁷⁸ But so far is it from being possible to preserve order and decorum without this regulation, that, if it were abolished, the Church would be in imminent danger of immediate convulsion and ruin. But if we feel the same necessity, to relieve which the Lord enjoined the sabbath upon the Jews, let no one plead that it does not belong to us. For our most provident and indulgent Father has been no less attentive to provide for our necessity than for that of the Jews. But why, it may be asked, do we not rather assemble on every day, that so all distinction of days may be removed? I sincerely wish that this were practised; and truly spiritual wisdom would be well worthy of some portion of time being daily allotted to it; but if the infirmity of many persons will not admit of daily assemblies, and charity does not permit us to require more of them, why should we not obey the rule which we have imposed upon us by the will of God?

XXXIII. I am obliged to be rather more diffuse on this point, because, in the present age, some unquiet spirits have been raising noisy contentions respecting the Lord's day. They complain that Christians are tinctured with Judaism, because they retain any observance of days. But I reply, that the Lord's day is not observed by us upon the principles of Judaism; because in this respect the difference between us and the Jews is very great. For we celebrate it not with scrupulous rigour, as a ceremony which we conceive to be a figure of some spiritual mystery, but only use it as a remedy necessary to the preservation of order in the Church. But they say, Paul teaches that Christians are not to be judged in the observance of it, because it is a shadow of something future.⁸⁷⁹ Therefore he is “afraid lest” he has “bestowed” on the Galatians “labour in vain,” because they continued to “observe days.”⁸⁸⁰ And in the Epistle to the Romans, he asserts him to be “weak in the faith,” who “esteemeth one day above another.”⁸⁸¹ But who, these furious zealots only excepted, does not see what observance the apostle intends? For they did not observe them for the sake of political and ecclesiastical order; but when they retained them as shadows of spiritual things, they were so far guilty of obscuring the glory of Christ and the light of the gospel. They did not, therefore, rest from their manual labours, as from employments which would divert them from sacred studies and meditations; but from a principle of superstition, imagining their cessation from labour to be still an expression of reverence for the mysteries formerly represented by it. This preposterous distinction of days the Apostle strenuously opposes; and not that legitimate difference which promotes the peace of the Christian Church. For in the churches which he founded, the sabbath was retained for this purpose. He prescribes the same day to the Corinthians, for making collections for the relief of the brethren at Jerusalem. If superstition be an object of fear, there was more danger in the holy days of the Jews, than in the Lord's days now observed by Christians. Now, whereas it was expedient for the destruction of superstition, the day which the Jews kept holy was abolished; and it being necessary for the preservation of decorum, order, and peace, in the Christian Church, another day was appointed for the same use.

XXXIV. However, the ancients have not without sufficient reason substituted what we call the Lord's day in the room of the sabbath. For since the resurrection of the Lord is the end and consummation of that true rest, which was adumbrated by the ancient sabbath, the same day which put an end to the shadows, admonishes Christians not to adhere to a shadowy ceremony. Yet I do not lay so much stress on the septenary number, that I would oblige the Church to an invariable adherence to it; nor will I condemn those churches which have other solemn days for their assemblies, provided they keep at a distance from superstition. And this will be the case, if they be only designed for the observance of discipline and well-regulated order. Let us sum up the whole in the following manner: As the truth was delivered to the Jews under a figure, so it is given to us without any shadows; first, in order that during our whole life we should meditate on a perpetual rest from our own works, that the Lord may operate within us by his Spirit; secondly, that every man, whenever he has leisure, should diligently exercise himself in private in pious reflections on the works of God, and also that we should at the same time observe the legitimate order of the Church, appointed for the hearing of the word, for the administration of the sacraments, and for public prayer; thirdly, that we should not unkindly oppress those who are subject to us. Thus vanish all the dreams of false prophets, who in past ages have infected the people with a Jewish notion, affirming that nothing but the ceremonial part of this commandment, which, according to them, is the appointment of the seventh day, has been abrogated, but that the moral part of it, that is, the observance of one day in seven, still remains. But this is only changing the day in contempt of the Jews, while they retain the same opinion of the holiness of a day; for on this principle the same mysterious signification would still be attributed to particular days, which they formerly obtained among the Jews. And indeed we see what advantages have arisen from such a sentiment. For those who adhere to it, far exceed the Jews in a gross, carnal, and superstitious observance of the sabbath; so that the reproofs, which we find in Isaiah, are equally applicable to them in the present age, as to those whom the Prophet reproved in his time. But the principal thing to be remembered is the general doctrine; that, lest religion decay or languish among us, sacred assemblies ought diligently to be held, and that we ought to use those external means which are adapted to support the worship of God.
