Direct. II. Be sure that you make no vow or covenant which God hath forbidden you to keep. It is rash vowing and swearing which is the common cause of perjury. You should, at the making of your vow, have seen into the bottom of it, and foreseen all the evils that might follow it, and the temptations which were like to draw you into perjury. He is virtually perjured as soon as he hath sworn, who sweareth to do that which he must not do; the preventive means are here the best.
Direct. III. Be sure you take no oath or vow which you are not sincerely resolved to perform.61 They that swear or vow with a secret reserve, that rather than they will be ruined by keeping it, they will break it, are habitually and reputatively perjured persons, even before they break it; besides that, they show a base, hypocritical, profligate conscience, that can deliberately commit so great a sin.
Direct. IV. See that all fleshly, worldly interest be fully subdued to the interest of your souls, and to the will of God. He that at the heart sets more by his body than his soul, and loveth his worldly prosperity above God, will lie, or swear, or forswear, or do any thing to save that carnal interest which he most valueth. He that is carnal and worldly at the heart, is false at the heart; the religion of such a hypocrite will give place to his temporal safety or commodity, and will carry him no further than the way is fair. It is no wonder that a proud man, or a worldling, will renounce both God and his true felicity for the world, seeing indeed he taketh it for his god and his felicity; even as a believer will renounce the world for God.62
Direct. V. Beware of inordinate fear of man, and of a distrustful withdrawing of your heart from God. Else you will be carried to comply with the will of man before the will of God, and to avoid the wrath of man before the wrath of God. Read and fear that heavy curse, Jer. xvii. 5, 6. God is unchangeable, and hath commanded you so far to imitate him, as "If a man vow a vow unto the Lord, or swear an oath to bind his soul with a bond, he shall not break his word; he shall do according to all that proceedeth out of his mouth," Numb. xxx. 2. But man is mutable, and so is his interest and his affairs; and therefore if you are the servants of men, you must swear one year, and forswear it, or swear the contrary, the next: when their interest requireth it, you must not be thought worthy to live among men, if you will not promise or swear as they command you; and when their interest altereth and requireth the contrary, you must hold all those bonds to be but straws, and break them for their ends.
Direct. VI. Be sure that you lose not the fear of God, and the tenderness of your consciences. When these are lost, your understanding, and sense, and life are lost; and you will not stick at the greatest wickedness; nor know when you have done it, what you did. If faith see not God continually present, and foresee not the great approaching day, perjury or any villany will seem tolerable, for worldly ends: for when you look but to men's present case, you will see that "the righteous and the wise, and their works, are in the hands of God; no man knoweth love or hatred by all that is before them. All things come alike to all; there is one event to the righteous, and to the wicked; to the good, and to the clean, and to the unclean; to him that sacrificeth, and to him that sacrificeth not: as is the good, so is the sinner; and he that sweareth, as he that feareth an oath," Eccles. ix. 1, 2. But in the end, men "shall discern between the righteous and the wicked," Mal. iii. 18. Therefore it is the believing foresight of the end, that by preserving the fear of God and tenderness of conscience, must save you from this, and all other heinous sin.
Direct. VII. Be not bold and rash about such dreadful things as vows. Run not as fearlessly upon them as if you were but going to your dinner; the wrath of God is not to be jested with. Usque ad aras, was the bounds even of a heathen's kindness to his friend. Meddle with oaths with the greatest fear, and caution, and circumspection. It is terrible here to find that you were mistaken, through any temerity, or negligence, or secret seduction of a carnal interest.
Direct. VIII. Especially be very fearful of owning any public doctrine, or doing any public act, which tendeth to harden others in their perjury, or to encourage multitudes to commit the sin.63 To be forsworn yourselves is a dreadful case; but to teach whole nations or churches to forswear themselves, or to plead for it, or justify it as a lawful thing, is much more dreadful. And though you teach not or own not perjury under the name of perjury, yet if first you will make plain perjury to seem no perjury, that so you may justify it, it is still a most inhuman, horrid act. God knoweth I insult not over the papists, with a delight to make any christians odious! but with grief I remember how lamentably they have abused our holy profession, while not only their great doctors, but their approved general council at the Lateran under Pope Innocent the Third, in the third canon hath decreed that the pope may depose temporal lords from their dominions, and give them unto others, and discharge their vassals from their allegiance and fidelity, if they be heretics, or will not exterminate heretics (even such as the holy men there condemned were, in the pope's account). To declare to many christian nations, that it is lawful to break their oaths and promises to their lawful lords and rulers, or their vows to God, and to undertake, by defending or owning this, to justify all those nations that shall be guilty of this perjury and perfidiousness, oh what a horrid crime is this! what a shame even unto human nature! and how great a wrong to the christian name!
Direct. IX. Understand and remember these following rules, to acquaint you how far a vow is obligatory: which I shall give you for the most part out of Dr. Sanderson, because his decisions of these cases are now of best esteem.
Rule I. The general rule laid down Numb. xxx. 2, 3, doth make a vow, as such, to be obligatory, though the party should have a secret equivocation or intent, that though he speak the words to deceive another, yet he will not oblige himself. Such a reserve not to oblige himself hindereth not the obligation, but proveth him a perfidious hypocrite. Dr. Sanderson, p. 23, Juramentum omne ex sua natura est obligatorium: ita ut si quis juret non intendens se obligare, nihilominus tamen suscipiendo juramentum ipso facto obligetur: that is, If he so far understand what he doth, as that his words may bear the definition of an oath or vow; otherwise if he speak the words of an oath in a strange language, thinking they signify something else, or if he speak in his sleep, or deliration, or distraction, it is no oath, and so not obligatory.
Rule II. Those conditions are to be taken as intended in all oaths, (whether expressed or no,) which the very nature of the thing doth necessarily imply64 (unless any be so brutish as to express the contrary). And these are all reducible to two heads: 1. A natural, and, 2. A moral impossibility. 1. Whoever sweareth to do any thing, or give any thing, is supposed to mean, If I live; and if I be not disabled in my body, faculties, estate; if God make it not impossible to be, &c. For no man can be supposed to mean, I will do it whether God will or not, and whether I live or not, and whether I be able or not. 2. Whoever voweth or sweareth to do any thing, must be understood to mean it, If no change of providence make it a sin; or if I find not, contrary to my present supposition, that God forbiddeth it. For no man that is a christian is to be supposed to mean when he voweth, I will do this, though God forbid it, or though it prove to be a sin; especially when men therefore vow it, because they take it to be a duty. Now as that which is sinful is morally impossible, so there
