Chapter 23: Of Lawful Oaths and Vows

Section 1

A lawful oath is a part of religious worship, wherein the person swearing in truth, righteousness and judgment, solemnly calleth God to witness what he asserteth or promiseth; and to judge him according to the truth or falsehood of what he sweareth.

Section 2

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.

Section 3

Whosoever taketh an oath, warranted by the Word of God, ought duly to consider the weightiness of so solemn an act, and therein to avouch nothing but what he is fully persuaded is the truth. Neither may any man bind himself by oath to anything but what is good and just, and what he believeth so to be, and what he is able and resolved to perform. Yet it is a sin to refuse an oath touching anything that is good and just, being imposed by lawful authority.

Section 4

An oath is to be taken in the plain and common sense of the words, without equivocation or mental reservation. It cannot oblige to sin; but in anything not sinful, being taken, it binds to performance, although to a man's own hurt: nor is it to be violated, although made to heretics or infidels.

Section 5

A vow which is of the like nature with a promissory oath, and ought to be made with the like religious care, and to be performed with the like faithfulness.

Section 6

Popish monastical vows of perpetual single life, professed poverty, and regular obedience, are so far from being degrees of higher perfection, that they are superstitious and sinful snares, in which no Christian may entangle himself.
