22.2. Of Lawful Oaths and Vows

The name of God only is that by which men ought to swear; and therein it is to be used with all holy fear and reverence. Therefore, to swear vainly or rashly, by that glorious and dreadful Name; or, to swear at all by any other thing, is sinful, and to be abhorred. Yet, as in matters of weight and moment, an oath is warranted by the Word of God, under the New Testament, as well as under the Old; so a lawful oath, being imposed by lawful authority, in such matters ought to be taken.

For discussion

1. The Assembly cited Deut. 6:13 in support of this answer. Read it in context — how does it bear on what is claimed here?
2. 11 passages are cited here. Which does the most work, and is anything claimed that the proofs do not obviously carry?
3. WSC Q53 treats the same ground. What does it add, and why might it put things differently?
4. WLC Q111 treats the same ground. What does it add, and why might it put things differently?
