CHAPTER XXXVI.  SWEARING.

“Thou shalt not take the name of the Lord, thy God in vain.”

A name is a sign, and respect for God Himself, as prescribed by the First Commandment through faith, hope, charity, prayer and religion, naturally implies respect for the name that stands for and signifies God.  Your name may, of itself, be nothing more than mere sound; but used in relation to what it represents, it is as sacred, and means as much to you, as your very person, for whatever is addressed to your name, whether of praise or blame, is intended to reach, and does effectively reach, yourself, to your honor or dishonor.  You exact therefore of men, as a right, the same respect for your name as for your person; and that is what God does in the Second Commandment.

The name of God represents all that He is.  He who profanes that name profanes a sacred thing, and is guilty of what is, in reality, a sacrilege.  To use it with respect and piety is an act of religion which honors God.  Men use and abuse this holy name, and first of all, by swearing, that is, by taking oaths.

In the early history of mankind, we are told, swearing was unknown.  Men were honest, could trust each other and take each other’s word.  But when duplicity, fraud and deception rose out of the corrupt heart of man, when sincerity disappeared, then confidence disappeared also, no man’s word was any longer good.  Then it was that, in order to put an end to their differences, they called upon God by name to witness the truth of what they affirmed.  They substituted God’s unquestioned veracity for their own questioned veracity, and incidentally paid homage to His truth; God went security for man.  Necessity therefore made man swear; oaths became a substitute for honesty.

A reverent use of the name of God, for a lawful purpose, cannot be wrong; on the contrary, it is good, being a public recognition of the greatest of God’s attributes—­truth.  But like all good things it is liable to be abused.  A too frequent use of the oath will easily lead to irreverence, and thence to perjury.  It is against this danger, rather than against the fact itself of swearing, that Christ warns us in a text that seems at first blush to condemn the oath as evil.  The common sense of mankind has always given this interpretation to the words of Christ.

An oath, therefore, is a calling upon God to witness the truth of what we say, and it means that we put our veracity on a par with His and make Him shoulder the responsibility of truthfulness.

To take an oath we must swear by God.  To swear by all the saints in the calendar would not make an oath.  Properly speaking, it is not even sufficient to simply say:  “I swear,” we must use the name of God.  In this matter, we first consider the words.  Do they signify a swearing, by God, either in their natural sense or in their general acceptation?  Or is there an intention of giving them this signification?  In conscience and before God, it is only when there is such an intention that there is a formal oath and one is held to the conditions and responsibilities thereof.
