“Nam : Non adulterabis : non occides : non furaberis : non falsum testimonium dices : non concupisces : et si quod est aliud mandatum, in hoc verbo instauratur : diliges proximum tuum sicut teipsum.”
“For this, Thou shalt not commit adultery, Thou shalt not kill, Thou shalt not steal, Thou shalt not bear false witness, Thou shalt not covet; and if there be any other commandment, it is briefly comprehended in this saying, namely, Thou shalt love thy neighbour as thyself.”
“The commandments “Do not commit adultery,” “Do not murder,” “Do not steal,” “Do not covet,” and any other commandments, are summed up in this one decree: “Love your neighbor as yourself.””
“For the commandments, “You shall not commit adultery,” “You shall not murder,” “You shall not steal,” “You shall not covet,” and whatever other commandments there are, are all summed up in this saying, namely, “You shall love your neighbor as yourself.””
“For this, Thou shalt not commit adultery, Thou shalt not kill, Thou shalt not steal, Thou shalt not covet, and if there be any other commandment, it is summed up in this word, namely, Thou shalt love thy neighbor as thyself.”
II. Of charity: Owe no man any thing; opheilete—you do owe no man any thing; so some read it: "Whatever you owe to any relation, or to any with whom you have to do, it is eminently summer up and included in this debt of love. But to love one another, this is a debt that must be always in the paying, and yet always owing." Love is a debt. The law of God and the interest of mankind make it so. It is not a thing which we are left at liberty about, but it is enjoined us, as the principle and summary of all duty owing one to another; for love is the fulfilling of the law; not perfectly, but it is a good step towards it. It is inclusive of all the duties of the second table, which he specifies, v. 9, and these suppose the love of God. See 1 John 4 20. If the love be sincere, it is accepted as the fulfilling of the law. Surely we serve a good master, that has summed up all our duty in one word, and that a short word and a sweet word—love, the beauty and harmony of the universe. Loving and being loved is all the pleasure, joy, and happiness, of an intelligent being. God is love (1 John 4 16), and love is his image upon the soul: where it is, the soul is well moulded, and the heart fitted for every good work. Now, to prove that love is the fulfilling of the law, he gives us, 1. An induction of particular precepts, v. 9. He specifies the last five of the ten commandments, which he observes to be all summed up in this royal law, Thou shalt love thy neighbour as thyself—with an as of quality, not of equality—"with the same sincerity that thou lovest thyself, though not in the same measure and degree." He that loves his neighbour as himself will be desirous of the welfare of his neighbour's body, goods, and good name, as of his own. On this is built that golden rule of doing as we would be done by. Were there no restraints of human laws in these things, no punishments incurred (which the malignity of human nature hath made necessary), the law of love would of itself be effectual to prevent all such wrongs and injuries, and to keep peace and good order among us. In the enumeration of these commandments, the apostle puts the seventh before the sixth, and mentions this first, Thou shalt not commit adultery; for though this commonly goes under the name of love (pity it is that so good a word should be so abused) yet it is really as great a violation of it as killing and stealing is, which shows that true brotherly love is love to the souls of our brethren in the first place. He that tempts others to sin, and defiles their minds and consciences, though he may pretend the most passionate love (Prov 7 15, 18), does really hate them, just as the devil does, who wars against the soul. 2. A general rule concerning the nature of brotherly love: Love worketh no ill (v. 10)—he that walks in love, that is actuated and governed by a principle of love, worketh no ill; he neither practises nor contrives any ill to his neighbour, to any one that he has any thing to do with: ouk ergazetai. The projecting of evil is in effect the performing of it. Hence devising iniquity is called working evil upon the bed, Mic 2 1. Love intends and designs no ill to any body, is utterly against the doing of that which may turn to the prejudice, offence, or grief of any. It worketh no ill; that is, it prohibits the working of any ill: more is implied than is expressed; it not only worketh no ill, but it worketh all the good that may be, deviseth liberal things. For it is a sin not only to devise evil against thy neighbour, but to withhold good from those to whom it is due; both are forbidden together, Prov 3 27-29. This proves that love is the fulfilling of the law, answers all the end of it; for what else is that but to restrain us from evil-doing, and to constrain us to well-doing? Love is a living active principle of obedience to the whole law. The whole law is written in the heart, if the law of love be there.
But that you love one another. This is a debt, says St. Chrysostom, which we are always to be paying, and yet always remains, and is to be paid again. — He that loveth his neighbour, hath fulfilled the law. Nay, he that loves his neighbour, as he ought, loves him for God’s sake, and so complies with the other great precept of loving God: and upon these two precepts (as Christ himself taught us, Matthew xxii. 40.) depends the whole law and the prophets. (Witham)
Verses 8-10 Christians must avoid useless expense, and be careful not to contract any debts they have not the power to discharge. They are also to stand aloof from all venturesome speculations and rash engagements, and whatever may expose them to the danger of not rendering to all their due. Do not keep in any one's debt. Give every one his own. Do not spend that on yourselves, which you owe to others. But many who are very sensible of the trouble, think little of the sin, of being in debt. Love to others includes all the duties of the second table. The last five of the ten commandments are all summed up in this royal law, Thou shalt love thy neighbour as thyself; with the same sincerity that thou lovest thyself, though not in the same measure and degree. He that loves his neighbour as himself, will desire the welfare of his neighbour. On this is built that golden rule, of doing as we would be done by. Love is a living, active principle of obedience to the whole law. Let us not only avoid injuries to the persons, connexions, property, and characters of men; but do no kind or degree of evil to any man, and study to be useful in every station of life.
