The Needlessness And The Folly Of Oaths

5:12 Above all things, my brothers, do not swear, neither by heaven nor by earth nor by any other oath. Let your yes be a simple yes and your no a simple no, lest you fall under judgment.

James is repeating the teaching of Jesus in the Sermon on the Mount ( Matthew 5:33-37 ), teaching which was very necessary in the days of the early church. James is not thinking of what we call bad language but of confirming a statement or a promise or an undertaking by an oath. In the ancient world, there were two evil practices.

(i) There was a distinction--especially in the Jewish world--between oaths which were binding and oaths which were not binding. Any oath in which the name of God was directly used was considered to be definitely binding; but any oath in which direct mention of the name of God was not made was held not to be binding. The idea was that, once God's name was definitely used, he became an active partner in the transaction, but he did not become a partner unless his name was so introduced. The result of this was that it became a matter of skill and sharp practice to find an oath which was not binding. This made a mockery of the whole practice of confirming anything by an oath.

(ii) There was in this age an extraordinary amount of oath-taking. This in itself was quite wrong. For one thing, the value of an oath depends to a large extent on the fact of it being very seldom necessary to take one. When oaths became a commonplace, they ceased to be respected as they ought to be. For another thing, the practice of taking frequent oaths was nothing other than a proof of the prevalence of lying and cheating. In an honest society no oath is needed; it is only when men cannot be trusted to tell the truth that they have to be put upon oath.

In this the ancient writers on morals thoroughly agreed with Jesus. Philo says, "Frequent swearing is bound to beget perjury and impiety." The Jewish Rabbis said, "Accustom not thyself to vows, for sooner or later thou wilt swear false oaths." The Essenes forbade all oaths. They held that if a man required an oath to make him tell the truth, he was already branded as untrustworthy. The great Greeks held that the best guarantee of any statement was not an oath but the character of the man who made it; and that the ideal was to make ourselves such that no one would ever think of demanding an oath from us because he would be certain that we would always speak the truth.

The New Testament view is that every word is spoken in the presence of God and ought, therefore, to be true; and it would agree that the Christian must be known to be a man of such honour that it will be quite unnecessary ever to put him on oath. The New Testament would not entirely condemn oaths but it would deplore the human tendency to falsehood which on occasion makes oaths necessary.
