Institutes 4.13.2 — OF VOWS. THE MISERABLE ENTANGLEMENTS CAUSED BY VOWING RASHLY.

**OF VOWS. THE MISERABLE ENTANGLEMENTS CAUSED BY VOWING RASHLY.**

If we would avoid error in deciding what vows are legitimate, and what preposterous, three things must be attended to—viz. who he is to whom the vow is made; who we are that make it; and, lastly, with what intention we make it. In regard in the first, we should consider that we have to do with God, whom our obedience so delights, that he abominates all will-worship, how specious and splendid soever it be in the eyes of men ( Col. 2:23 ). If all will-worship, which we devise without authority, is abomination to God, it follows that no worship can be acceptable to him save that which is approved by his word. Therefore, we must not arrogate such licence to ourselves as to presume to vow anything to God without evidence of the estimation in which he holds it. For the doctrine of Paul, that whatsoever is not of faith is sin ( Rom. 14:23 ), while it extends to all actions of every kind, certainly applies with peculiar force in the case where the thought is immediately turned towards God. Nay, if in the minutest matters (Paul was then speaking of the distinction of meats) we err or fall, where the sure light of faith shines not before us, how much more modesty ought we to use when we attempt a matter of the greatest weight? For in nothing ought we to be more serious than in the duties of religion. In vows, then, our first precaution must be, never to proceed to make any vow without having previously determined in our conscience to attempt nothing rashly. And we shall be safe from the danger of rashness when we have God going before, and, as it were, dictating from his word what is good, and what is useless.
