John 15:12

"This," He says, "is my injunction, that ye love one another, as I have loved you." Whether we call it injunction or commandment, both are the rendering of the same Greek word, entole. But He had already made this same announcement on a former occasion, when, as ye ought to remember, I expounded it to you to the best of my ability. For this is what He says there, "A new commandment I give unto you, that ye love one another; as I have loved you, that ye also love one another." And so the repetition of this commandment is its commendation: only that there He said, "A new commandment I give unto you;" and here, "This is my commandment:" there, as if there had been no such commandment before; and here, as if He had no other commandment to give them. But there it is spoken of as "new," to keep us from persevering in our old courses; here, it is called "mine," to keep us from treating it with contempt. But when He said in this way here, "This is my commandment," as if there were none else, what are we to think, my brethren? Is, then, the commandment about that love wherewith we love one another, His only one? Is there not also another that is still greater,-that we should love God? Or has God in very truth given us such a charge about love alone, that we have no need of searching for others? There are three things at least that the apostle commends when he says, "But now abide faith, hope, charity, these three; but the greatest of these is charity." And although in charity, that is, in love, are comprehended the two commandments; yet it is here declared to be the greatest only, and not the sole one. Accordingly, what a host of commandments are given us about faith, what a multitude about hope! Who is there that could collect them together, or suffice to number them? But let us ponder the words of the same apostle: "Love is the fullness of the law." And so, where there is love, what can be wanting? and where it is not, what is there that can possibly be profitable? The devil believes, but does not love: no one loveth who doth not believe. One may, indeed, hope for pardon who does not love, but he hopes in vain; but no one can despair who loves. Therefore, where there is love, there of necessity will there be faith and hope; and where there is the love of our neighbor, there also of necessity will be the love of God. For he that loveth not God, how loveth he his neighbour as himself, seeing that he loveth not even himself? Such an one is both impious and iniquitous; and he that loveth iniquity, manifestly loveth not, but hateth his own soul. Let us, therefore, be holding fast to this precept of the Lord, to love one another; and then all else that is commanded we shall do, for all else we have contained in this. But this love is distinguished from that which men bear to one another as such; for in order to mark the distinction, it is added, "as I have loved you." And wherefore is it that Christ loveth us, but that we may be fitted to reign with Christ? With this aim, therefore, let us also be loving one another, that we may manifest the difference of our love from that of others, who have no such motive in loving one another, because the love itself is wanting. But those whose mutual love has the possession of God Himself for its object, will truly love one another; and, therefore, even for the very purpose of loving one another, they love God. There is no such love as this in all men; for few have this motive for their love one to another, that God may be all in all.

(Tract. lxxxiii. 3) Where then love is, what can be wanting? Where it is not, what can profit? But this love is distinguished from men's love to each other as men, by adding, As I have loved you. To what end did Christ love us, but that we should reign with Him? Let us therefore so love one another, as that our love be different from that of other men; who do not love one another, to the end that God may be loved, because they do not really love at all. They who love one another for the sake of having God within them, they truly love one another.

(Hom. xxvii. in Evang.) But when all our Lord's sacred discourses are full of His commandments, why does He give this special commandment respecting love, if it is not that every commandment teaches love, and all precepts are one? Love and love only is the fulfilment of every thing that is enjoined. As all the boughs of a tree proceed from one root, so all the virtues are produced from one love: nor hath the branch, i. e. the good work, any life, except it abide in the root of love.

Having said, If ye keep My commandments, ye shall abide in My love, He shows what commandments they are to keep: This is My commandment, That ye love one another.

"These things have I spoken unto you, that My joy might remain in you, and that your joy might be fulfilled"; that is, "that ye might not be separated from Me that ye might not cut short your course. Ye were rejoicing in Me, and ye were rejoicing exceedingly, but despondency hath fallen upon you. This then I remove, that joy may come at the last, showing that your present circumstances are fit cause, not for pain, but for pleasure. I saw you offended; I despised you not; I said not, 'Why do ye not continue noble?' But I spake to you words which brought comfort with them. And so I wish ever to keep you in the same love. Ye have heard concerning a kingdom, ye rejoiced. In order therefore that your joy might be fulfilled, I have spoken these things unto you."
