The Eighth Commandment. make accusation to regular judges? Ah, I cannot prove it publicly, and hence I might be silenced and turned away in a harsh manner [incur the penalty of a false accusation]. "Ah, indeed, do you smell the roast?" If you do not trust yourself to stand before the proper authorities and to make answer, then hold your tongue. But if you know it, know it for yourself and not for another. For if you tell it to others, although it be true, you will appear as a liar, because you cannot prove it, and you are, besides acting like a knave. For we ought never to deprive any one of his honor or good name unless it be first taken away from him publicly.
False witness, then, is everything which cannot be properly proved. Therefore, what is not manifest upon sufficient evidence no one shall make public or declare for truth; and in short, whatever is secret should be allowed to remain secret, or, at any rate, should be secretly reproved, as we shall hear. Therefore, if you encounter an idle tongue which betrays and slanders some one, contradict such a one promptly to his face, that he may blush thus many a one will hold his tongue who else would bring some poor man into bad repute from which he would not easily extricate himself. For honor and a good name are easily taken away, but not easily restored.
Thus you see that it is summarily forbidden to speak any evil of our neighbor, however the civil government, preachers, father and mother excepted, on the understanding that this commandment does not allow evil to go unpunished. Now, as according to the Fifth Commandment no one is to be injured in body, and yet Master Hannes [the executioner] is excepted, who by virtue of his office does his neighbor no good, but only evil and harm, and nevertheless does not sin against God's commandment, because God has on His own account instituted that office; for He has reserved punishment for His own good pleasure, as He threatens in the First Commandment, -- just so also, although no one has a right in his own person to judge and condemn anybody, yet if they to whose office it belongs fail to do it, they sin as well as he who would do so of his own accord, without such office. For here necessity requires one to speak of the evil, to prefer charges, to investigate and testify; and it is not different from the case of a physician who is sometimes compelled to examine and handle the patient whom he is to cure in secret parts. Just so governments, father and mother, brothers and sisters, and other good friends, are under obligation to each other to reprove evil wherever it is needful and profitable.
But the true way in this matter would be to observe the order according to the Gospel, Matt. 18, 15, where Christ says: If thy brother shall trespass against thee, go and tell him his fault between thee and him alone. Here you have a precious and excellent teaching for governing well the tongue, which is to be carefully observed against this detestable misuse.
Let this, then, be your rule, that you do not too readily spread evil concerning your neighbor and slander him to others, but admonish him privately that he may amend [his life]. Likewise, also, if some one report to you what this or that one has done, teach him, too, to go and admonish him personally if he have seen it himself; but if not, that he hold his tongue.
