Then the men feared Yahweh exceedingly; and they offered a sacrifice to Yahweh, and made vows.
And here we may easily learn how foolishly the Sophists of our day heap together all passages of Scripture which make any mention of vows; for they think that we are to be overwhelmed by that term alone, when we condemn their false vows. But no one of us has ever denied or does deny, that it is lawful to vows provided it be done according to what the Law and the Gospel prescribes. What we hold is, — that men are not thoughtlessly to obtrude on God what comes uppermost, but that they are to vow what he approves, and also, that they regard a right and just end in vowing, even to testify their gratitude to God. But in common vows which are made, there are the grossest errors, as also in the whole of the Papal worship; for they vow this and that to God indiscriminately, and regard not what the Lord requires or approves: one, on certain days, abstains from meat; another combs not his head: and a third trots away on some pilgrimage. All these things, we know, are rejected by God. And further, when they vow nothing but what God approves, it is yet done for a wrong purpose: for they seek in this way to bind God to themselves, and the diabolical conceit of merits ever possesses their minds. And, lastly, they consider not what they can do; they vow perpetual celibacy when at the same time incontinence burns them; and thus we see that, like the giants, they fight with God himself; and, in the meantime, they allow themselves an unbridled liberty as to whatever they vow.
