_Prop._ VIII. In case I misunderstood the imposed oath through my own default, I am bound to keep it in both senses, (my own and the imposer's,) if both be consistent and lawful to be done. For I am bound to it in my own sense, because it was formally my oath or vow which I intended. And I am bound to it in his sense, because I have in justice made the thing his due. As if the king command me to vow that I will serve him in wars against the Turk; and I misunderstand him as if he meant only to serve him with my purse; and so I make a vow with this intent, to expend part of my estate to maintain that war; whereas the true sense was that I should serve him with my person: in this case, I see not but I am bound to both.
Indeed if it were a promise that obliged me only to the king, then I am obliged no further and no longer than he will; for he can remit his own right: but if by a vow I become obliged directly to God himself as a party, then no man can remit his right, and I must perform my vow as made to him.
_Rule_ XIII. If any impose an ambiguous oath, and refuse to explain it, and require you only to swear in these words, and leave you to your own sense, Dr. Sanderson thinketh that an honest man should suspect some fraud in such an oath, and not take it at all till all parties are agreed of the sense.[72] And I think he should not take it at all, unless there be some other cause that maketh it his duty. But if a lawful magistrate command it, or the interest of the church or state require it, I see not but he may take it, on condition that in the plain and proper sense of the words the oath be lawful, and that he openly profess to take it only in that sense.
_Rule_ XIV. If any power should impose an oath, or vow, or promise, which in the proper, usual sense were downright impious, or blasphemous, or sinful, and yet bid me take it in what sense I pleased, though I could take it in such a sense as might make it no real consent to the impiety, yet it would be impious in the sense of the world, and of such heinous consequence as will make it to be unlawful. As if I must subscribe, or say, or swear these words, There is no God; or, Scripture is untrue; though it is easy to use these or any words in a good sense, if I may put what sense I will upon them, yet the public sense of them is blasphemy; and I may not publicly blaspheme, on pretence of a private right sense and intention.
_Rule_ XV. If the oath imposed be true in the strict and proper sense, yet if that sense be not vulgarly known, nor sufficiently manifest to be the imposer's sense, and if the words are false or blasphemous in the vulgar sense of those that I have to do with, and that must observe and make use of my example, I must not take such an oath, without leave to make my sense as public as my oath. As if I were commanded to swear, That God hath no foreknowledge, no knowledge, no will, &c.; it were easy to prove that these terms are spoken primarily of man, and that they are attributed to God but analogically or metaphorically, and that God hath no such human acts _formaliter_, but _eminenter_, and that _forma dat nomen_, and so that strictly it is not knowledge and will in the primary, proper notion, that God hath at all, but something infinitely higher, for which man hath no other name. But though thus the words are true and justifiable in the strictest, proper sense, yet are they unlawful, because they are blasphemy in the vulgar sense: and he that speaks to the vulgar is supposed to speak with the vulgar; unless he as publicly explain them.
_Rule_ XVI. If the supreme power should impose an oath or promise, which in the ordinary, obvious sense were sinful, and an inferior officer would bid me take it in what sense I pleased, I might not therefore take it: because that such an officer hath no power to interpret it himself; much less to allow me to take it in a private sense. But if the lawgiver that imposeth it bid me take it in what sense I will, and give me leave to make my sense as public as my oath, I may take it, if the words be but dubious, and not apparently false or sinful: (so there be no reason against it, _aliunde_, as from ill consequents, &c.)
_Rule_ XVII. If any man will say in such a case, (when he thinketh that the imposer's sense is bad,) I take not the same oath or engagement which is imposed, but another in the same words, and I suppose not inferior officers authorized to admit any interpretation, but I look at them only as men that can actually execute or not execute the laws upon me; and so I take a vow of my own according to my own sense, though in their words, as a means of my avoiding their severities: as this is a collusion in a very high and tender business, so that person (if the public sense of the oath be sinful) must make his professed sense as public as his oath or promise; it being no small thing to do that which in the public sense is impious, and so to be an example of perfidiousness to many.
