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, [pg 350] 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 [pg 352] 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 [pg 353] 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 [pg 355] 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 [pg 356] 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.
