The Apostle spoke somewhat indefinitely about the oath: "Men swear by one greater than themselves." That is, they swear by what is higher and more important than man.
Probably he had in mind the custom of his time, when people swore not only by the name of God, but also by heaven and earth, the temple and the altar.
Yet all these forms of oath, according to the explanation of Christ the Savior Himself, have one true meaning. Directly or indirectly they refer to God, and in Him and in His name they have their power and importance.
"He who swears by the temple swears by it and by Him who dwells in it; and he who swears by heaven swears by the throne of God and by Him who sits upon it" (Mt 23:21-22).
But how do we dare to use the holy and fearful name of God in our assurances and promises? Is this boldness permissible? In what cases is it permissible?
The answer to all these questions can be found in one apostolic saying: "In every dispute the oath is final for confirmation." That is, an oath is the final and extreme means of assurance in every case where dispute must be ended or doubt removed.
Therefore, if a dispute or doubt arising in relations between men is not so important that it requires strengthened measures to remove it, one should not resort to an oath.
Nor should one do so if there are simple and nearer means for this purpose, found in the properties and circumstances of matters and relations.
If one can be content with incomplete assurance without great harm, especially public harm, then ordinary prudence will not advise resorting to the extreme means of assurance.
In such cases, a pious feeling should not permit an oath by the name of God.
For example, you may want people to believe your word in conversation, or your promise in common life. In the multitude of such cases, which are mostly of little importance, resorting to an oath would be as bold as it is unnecessary.
For the degree of assurance needed here, there are simple and nearer means. Always speak the truth precisely and without evasiveness, and your simple word will be believed as an oath.
Do not make promises when you are not sure they can easily be fulfilled. Fulfill the promises you have made unwaveringly, and your simple promise will be believed as an oath.
To such cases belong both the ancient commandment, "You shall not take the name of the Lord your God in vain" (Ex 20:7), and Christ's commandment, "Do not swear at all" (Mt 5:34).
The Apostle's exhortation also belongs here: "Do not swear, either by heaven or by earth or by any other oath. Let your yes be yes, and your no, no, lest you fall into hypocrisy" (Jas 5:12).
But there are cases of another kind, in which ordinary means are insufficient for removing doubt and attaining assurance. Failure to attain assurance would bring extreme harm, not only private but also public.
From this arises the necessity, and from necessity the duty, to attain the "final confirmation" with the utmost effort. One must resort to the extreme means of assurance that is possible.
The sovereign and the state require faithfulness from subjects in general, and in particular services, offices, and commissions. Firm assurance in this faithfulness is absolutely necessary.
Without it, public order would not be secured, and public safety itself would not exist. By what then is faithfulness to be secured?
By laws? But for laws to have full force and effect, strict faithfulness is needed in their application. Therefore the proposed question is not resolved here, but only takes on a particular form.
By what is faithfulness in the application of laws to be secured? By what then? By honesty known beforehand?
It is easier to find time and means for this in the limited circle of private relations than in the boundless expanse of state relations.
Authority undoubtedly uses its nearest and most important instruments with prior testing and inquiry, insofar as the limited human gaze can reach and penetrate.
But can testing and inquiry decisively determine the honesty of each of thousands and countless people before using them as instruments of the state?
Again the question returns: by what is faithfulness to be secured? By a word of honor?
A word of honor can be accepted as security only from the mouth of a man whose honesty has been tested. Where prior full testing of honesty is difficult to accomplish, a word that proclaims itself honorable does not secure anything.
Who does not know that the so-called word of honor is also given by those who have not secured its fulfillment even for themselves, and do not even think about fulfilling it?
By what then is faithfulness to be secured? By fear of punishments?
How unpleasant it would be, if it were even possible, to establish general peace on general fear alone. But this is not possible.
There can be violations of faithfulness which human insight cannot discover and human justice cannot pursue. Fear of punishment is necessary and useful for restraining those inclined to crimes.
But it is not sufficient for forming the quality of faithful subjects. Thus the insufficiency of nearer and ordinary means for securing faithfulness leads to the extreme means.
This is the sealing of promised faithfulness with the great and fearful name of God. Thus each man may honor faithfulness as he reveres God.
Thus whoever would dare to touch his promise would inevitably meet the name of God. This name is not merely a sound pronounced, but the invoked power of God.
It penetrates souls, tests hearts, blesses the faithful, and punishes the unfaithful.
That this "final confirmation," this extreme means of assurance among men, is not simply a human institution can easily be seen. An oath is not only an invention of the art of governing peoples.
The heavenly kingdom itself accepts, confirms, and sanctifies this support of the earthly kingdom. This is clear from the fact that God Himself swears.
"By Myself I have sworn, says the Lord" (Gen 22:16) to Abraham. The Apostle explains this word of the Lord precisely as an image of God's oath.
"When God made a promise to Abraham, since He had no one greater by whom to swear, He swore by Himself" (Heb 6:13).
There is no doubt that by condescension God here gives His promise the form of human assurance. Yet there is also no doubt that God takes into His hands only those earthly instruments which are pure and worthy of heaven.
An oath by the name of God in the faithful performance of public service, or in the faithful fulfillment of a public task, is needed both to assure authority and society, and to strengthen the one who binds himself to faithfulness.
Does faithfulness not often require not only self-denial, but also self-sacrifice? Does it not meet temptations?
Sometimes these are crude temptations, which are not always as easy to repel as they are to notice. Sometimes they are subtle temptations, in which one can become entangled almost imperceptibly.
A self-confident man will rely on himself in this. Yet he will hardly be an exception to the prophetic judgment that "every man is a lie" (Ps 115:2), that is, outside the help of God.
But a man with greater self-knowledge would not be at rest from doubt about himself, unless he fled to God and established his hope in Him.
"O Lord, faithful in Thy words and holy in all Thy works" (Ps 144:13), bless the faithfulness of my word and the holiness of my work.
Show me truth and righteousness. Grant me readiness for self-sacrifice for their sake, firmness to stand against the assaults of powerful falsehood, and foresight not to become entangled in the nets of cunning or partiality.
Thus it is natural for the heart of a man to speak when he sincerely desires to preserve faithfulness in public service or a public task.
Thus also the form of the oath prescribed by law from the days of our forefathers commands one to say: "May the Lord God help me in soul and body."
May the thought of unfaithfulness to the oath be far from us. But so that it may be more surely removed, strike it as with an arrow by the dread word of God: "The Lord will not hold guiltless him who takes His name in vain" (Ex 20:7).
If "the Lord will not hold guiltless him who takes His name" in vain, uselessly, frivolously, and without need, what should he expect who, giving an oath before God, would use God's name with evil intent?
What should he expect if he uses it sacrilegiously, to cover the uncleanness of his unfaithfulness with its holiness?
"Thou shalt destroy all who speak falsehood" (Ps 5:7). But, Lord, wilt Thou not destroy before others those who speak falsehood before Thy name and before Thy face?
They lie, like Ananias and Sapphira, not to men, but to Thee, O God. When the Apostle Peter exposed Ananias with these very words, "You have not lied to men, but to God," Ananias heard these words, fell down, and expired.
Then Sapphira, after a similar rebuke, "immediately fell down at his feet and expired" (Acts 5:4-5, 10).
This example, and many examples outside sacred history, show that falsehood before the name of God and before the face of God, perjured falsehood, seems to bring heavenly Justice to impatience.
It draws down the fearsome and sudden blows of destiny.
To these reflections on the importance of the oath, I hope you will add, even without my assistance, reflection on the importance of the matter for which you give the oath.
Upon those whom you choose will depend no small share of public order, the peace of many, and especially the peace of those who depend on you and are entrusted to your care.
Sometimes, perhaps, the peace of some of you will also depend on them, as well as the maintenance of the dignity of your exalted estate.
Choose in such a way that you will not later reproach yourselves, and that you will not anger God. Find worth if it is hidden. Know how to attract it if it withdraws.
On the contrary, place a barrier before the ambition of unworthiness. Do not place yourselves below the unworthy by allowing them to outwit your action.
Justify the generous confidence of the autocratic Authority toward you. May purity of intention and action draw God's blessing upon the electors, the election, the elected, and the consequences of the election. Amen.
