29. Love being the chief element of all law, it comprehends, as has been made sufficiently clear, all commandments. Its one concern is to be useful to man and not harmful; therefore, it readily discovers the way. Recognizing the fact that man, from his ardent self-love, seeks to promote his own interests and avoid injuring them, love endeavors to adopt the same course toward others. We will consider the commandment just cited, noticing how ingeniously and wisely it is arranged. It brings out four thoughts. First, it states who is under obligation to love: thou--the nearest, noblest, best individual we can command. No one can fulfil the Law of God for another; each must do it for himself. As Paul says (Gal 6, 5), "Each man shall bear his own burden." And (2 Cor 5, 10): "For we must all be made manifest before the judgment-seat of Christ; that each one may receive the things done in the body, according to what he hath done, whether it be good or bad." So it is said, "Thou, thou thyself, must love;" not, "Let someone else love for you." Though one can and should pray that God may be gracious to another and help him, yet no one will be saved unless he himself fulfils God's command. It is not enough merely to pray that another may escape punishment, as the venders of indulgences teach; much rather, we should pray that he become righteous and observe God's precepts. 30. Second, the commandment names the most noble virtue--love. It does not say, "Thou shalt feed thy neighbor, give him drink, clothe him," all of which things are inestimably good works; it says, "Thou shalt love him." Love is the chief virtue, the fountain of all virtues. Love gives food and drink; it clothes, comforts, persuades, relieves and rescues. What shall we say of it, for behold he who loves gives himself, body and soul, property and honor, all his powers inner and external, for his needy neighbor's benefit, whether it be friend or enemy; he withholds nothing wherewith he may serve another. There is no virtue like love; there can be no special work assigned it as in the case of limited virtues, such as chastity, mercy, patience, meekness, and the like. Love does all things. It will suffer in life and in death, in every condition, and that even for its enemies. Well may Paul here say that all other commandments are briefly comprehended in the injunction, "Thou shalt love thy neighbor as thyself."
