Thus we have now the sum and general understanding of this commandment, to wit, that no one do any injury with the tongue to his neighbor, whether friend or foe, nor speak evil of him, no matter whether it be true or false, unless it be done by commandment or for his reformation, but that every one employ his tongue and make it serve for the best of every one else, to cover up his neighbor's sins and infirmities, excuse them, palliate and garnish them with his own reputation. The chief reason for this should be the one which Christ alleges in the Gospel, in which He comprehends all commandments respecting our neighbor, Matt. 7, 12: Whatsoever ye would that men should do to you, do ye even so to them. Even nature teaches the same thing in our own bodies, as St. Paul says, 1 Cor. 12, 22: Much more, those members of the body which seem to be more feeble are necessary; and those members of the body which we think to be less honorable, upon these we bestow more abundant honor; and our uncomely parts have more abundant comeliness. No one covers his face, eyes, nose, and mouth, for they, being in themselves the most honorable members which we have, do not require it. But the most infirm members, of which we are ashamed, we cover with all diligence; hands, eyes, and the whole body must help to cover and conceal them. Thus also among ourselves should we adorn whatever blemishes and infirmities we find in our neighbor, and serve and help him to promote his honor to the best of our ability, and, on the other hand, prevent whatever may be discreditable to him. And it is especially an excellent and noble virtue for one always to explain advantageously and put the best construction upon all he may hear of his neighbor (if it be not notoriously evil), or at any rate to condone it over and against the poisonous tongues that are busy wherever they can pry out and discover something to blame in a neighbor, and that explain and pervert it in the worst way; as is done now especially with the precious Word of God and its preachers. There are comprehended therefore in this commandment quite a multitude of good works which please God most highly, and bring abundant good and blessing, if only the blind world and the false saints would recognize them. For there is nothing on or in entire man which can do both greater and more extensive good or harm in spiritual and in temporal matters than the tongue, though it is the least and feeblest member. The Ninth and Tenth Commandments Thou shalt not covet thy neighbor's house. Thou shalt not covet thy neighbor's wife, nor his man-servant, nor his maid-servant, nor his cattle, nor anything that is his.
