De Decalogo

Therefore, God, removing out of his sacred legislation all such impious deification of undeserving objects, has invited men to the honour of the one true and living God; not indeed that he has any need himself to be honoured; for being all-sufficient for himself, he has no need of any one else; but he has done so, because he wished to lead the race of mankind, hitherto wandering about in trackless deserts, into a road from which they should not stray, that so by following nature it might find the best end of all things, namely, the knowledge of the true and living God, who is the first and most perfect of all good things; from whom, as from a fountain, all particular blessings are showered upon the world, and upon the things are people in it.

Having now spoken of the second commandment to the best of our ability, let us proceed to investigate the one which follows with accuracy, as is pointed out by the order in which they come.

The next commandment is, "not to take the name of God in vain." Now the principle on which this order or arrangement proceeds is very plain to those who are gifted with acute mental vision; for the name is always subsequent in order to the subject of which it is the name; being like the shadow which follows the body.

Having, therefore, previously spoken of the existence of God, and also of the honour to be paid to the everlasting God; he then, following the natural order of connection proceeds to command what is becoming in respect of his name; for the errors of men with respect to this point are manifold and various, and assume many different characters.

That being which is the most beautiful, and the most beneficial to human life, and suitable to rational nature, swears not itself, because truth on every point is so innate within him that his bare word is accounted an oath. Next to not swearing at all, the second best thing is to keep one’s oath; for by the mere fact of swearing at all, the swearer shows that there is some suspicion of his not being trustworthy.

Let a man, therefore, be dilatory, and slow if there is any chance that by delay he may be able to avoid the necessity of taking an oath at all; but if necessity compels him to swear, then he must consider with no superficial

For an oath is the calling of God to give his testimony concerning the matters which are in doubt; and it is a most impious thing to invoke God to be witness to a lie.

Come now, if you please, and with your reason look into the mind of the man who is about to swear to a falsehood; and you will see that it is not tranquil, but full of disorder and confusion, accusing itself, and enduring all kinds of insolence and evil speaking;

for the conscience which dwells in, and never leaves the soul of each individual, not being accustomed to admit into itself any wicked thing, preserves its own nature always such as to hate evil, and to love virtue, being itself at the same time an accuser and a judge; being roused as an accuser it blames, impeaches, and is hostile; and again as a judge it teaches, admonishes, and recommends the accused to change his ways, and if he be able to persuade him, he is with joy reconciled to him, but if he be not able to do so, then he wages an endless and implacable war against him, never quitting him neither by day, nor by night, but pricking him, and inflicting incurable wounds on him, until he destroys his miserable and accursed life.

"What sayest thou?" I should say to the perjured man, "will you dare to go to any one of your own acquaintances and say, My friend, come and bear witness for me that you have seen and heard, and been present at a whole catalogue of things which you have neither seen, nor heard? I think not; for that would be an act of incurable insanity;

with what face can you while sober, and while appearing to be master of yourself look upon your friend, and say, By reason of our acquaintance and companionship, act unjustly, violate the law, commit impiety for my sake; for it is plain that if he heard such a request, he would quickly renounce that companionship which you now believe to exist, reproaching himself for having ever had any friendship at all with a man of such a character as you, and would flee from you, as from a savage, and maddened, wild beast.

"Will you then, without shame call upon God, the father and sovereign of the world, to give his testimony in favour of those things, to witness which you will not venture even

If you know it not you are an atheist, and atheism is the beginning of all iniquity, and, in addition to your atheism, you are also adding the wickedness of an oath, by swearing by him who in your opinion is not attending to you, nor paying any regard to human affairs.

But if you are well assured that he does exert his providence in respect of such matters, still you are not free from the charge of excessive impiety, saying to God, if not with your mouth and tongue, still at all events with your conscience: Bear false witness for me, aid me in my wickedness, assist me in my impiety. I have but one hope of preserving a fair reputation among men, namely by concealing the truth; be thou wicked for another’s sake, you who are the better, for the sake of one who is worse; you who are God, the most excellent of all beings, for the sake of a man, and that too a wicked one.

But there are also some people who, without any idea of acquiring gain, do from a bad habit incessantly and inconsiderately swear upon every occasion, even when there is nothing at all about which any doubt is raised, as if they were desirous to fill up the deficiency of their argument with oaths, as if it would not be better to cut their conversation short, or I might rather say to utter nothing at all, but to preserve entire silence, for from a frequency of oaths arises a habit of perjury and impiety.

On which account the man who is going to take an oath ought to investigate everything with care and exceeding accuracy, considering whether the subject is of serious importance, and whether it has really taken place, and whether, if it has, he has comprehended it properly; and considering himself, also, whether he is pure in soul, and body, and tongue, having the first free from all violation of the law, the second from all defilement, and the last from all blasphemy.

For it is an impiety for any disgraceful words to be uttered by that mouth by which the most sacred name is also mentioned.

Let him also consider whether the place and the time are suitable; for before now I have known

And let him who pays but little heed to what has been said here know, in the first place, that he is impure and defiled; and, in the second place, that the most terrible punishments are constantly lying in wait for him; that justice who keeps her eye upon all human affairs, being implacable and inflexible towards all enormities of such a character; and, when she does not think fit to inflict her punishments at once, still exacting satisfaction with abundant usury whenever the opportunity seems to offer in combination with the general advantage. .

The fourth commandment has reference to the sacred seventh day, that it may be passed in a sacred and holy manner. Now some states keep the holy festival only once in the month, counting from the new moon, as a day sacred to God; but the nation of the Jews keep every seventh day regularly, after each interval of six days;
