1 John 4:8

“God,” then, being good, “is love,” it is said. Whose “love worketh no ill to his neighbour,” neither injuring nor revenging ever, but, in a word, doing good to all according to the image of God. “Love is,” then, “the fulfilling of the law;” like as Christ, that is the presence of the Lord who loves us; and our loving teaching of, and discipline according to Christ. By love, then, the commands not to commit adultery, and not to covet one’s neighbour’s wife, are fulfilled, [these sins being] formerly prohibited by fear.

18. It is better, then, that we affirm that concerning which we have no doubt, that God shall be seen by the inward man, which alone is able, in our present state, to see that love in commendation of which the apostle says, “God is love;” the inward man, which alone is able to see “peace and holiness, without which no man shall see the Lord.” For no fleshly eye now sees love, peace, and holiness, and such things; yet all of them are seen, so far as they can be seen, by the eye of the mind, and the purer it is the more clearly it sees; so that we may, without hesitation, believe that we shall see God, whether we succeed or fail in our investigations as to the nature of our future body, although, at the same time, we hold it to be certain that the body shall rise again, immortal and incorruptible, because on this we have the plainest and strongest testimony of Holy Scripture. …

2. This restoration of Leporius we could perhaps in nowise have accomplished, had you not previously censured and punished those things in him which required correction. So then the same Lord, our Divine Physician, using His own instruments and servants, has by you wounded him when he was proud, and by us healed him when he was penitent, according to his own saying, “I wound, and I heal.” The same Divine Ruler and Overseer of His own house has by you thrown down what was defective in the building, and has by us replaced with a well-ordered structure what he had removed. The same Divine Husbandman has in His careful diligence by you rooted up what was barren and noxious in His field, and by us planted what is useful and fruitful. Let us not, therefore, ascribe glory to ourselves, but to the mercy of Him in whose hand both we and all our words are. …

6. The Holy Spirit also, whether we are to call Him that absolute love which joins together Father and Son, and joins us also from beneath, that so that is not unfitly said which is written, “God is love;” how is He not also Himself wisdom, since He is light, because “God is light”? or whether after any other way the essence of the Holy Spirit is to be singly and properly named; then, too, since He is God, He is certainly light; and since He is light, He is certainly wisdom. But that the Holy Spirit is God, Scripture proclaims by the apostle, who says, “Know ye not that ye are the temple of God?” and immediately subjoins, “And the Spirit of God dwelleth in you;” for God dwelleth in His own temple. …

11. Wherefore they who seek God through those Powers which rule over the world, or parts of the world, are removed and cast away far from Him; not by intervals of space, but by difference of affections: for they endeavor to find a path outwardly, and forsake their own inward things, within which is God. Therefore, even although they may either have heard some holy heavenly Power, or in some way or another may have thought of it, yet they rather covet its deeds at which human weakness marvels, but do not imitate the piety by which divine rest is acquired. For they prefer, through pride, to be able to do that which an angel does, more than, through devotion, to be that which an angel is. …

12. Let no one say, I do not know what I love. Let him love his brother, and he will love the same love. For he knows the love with which he loves, more than the brother whom he loves. So now he can know God more than he knows his brother: clearly known more, because more present; known more, because more within him; known more, because more certain. Embrace the love of God, and by love embrace God. That is love itself, which associates together all good angels and all the servants of God by the bond of sanctity, and joins together us and them mutually with ourselves, and joins us subordinately to Himself. …

31. As, then, we call the only Word of God specially by the name of Wisdom, although universally both the Holy Spirit and the Father Himself is wisdom; so the Holy Spirit is specially called by the name of Love, although universally both the Father and the Son are love. But the Word of God, i.e. the only-begotten Son of God, is expressly called the Wisdom of God by the mouth of the apostle, where he says, “Christ the power of God, and the wisdom of God.” But where the Holy Spirit is called Love, is to be found by careful scrutiny of the language of John the apostle, who, after saying, “Beloved, let us love one another, for love is of God,” has gone on to say, “And every one that loveth is born of God, and knoweth God. He that loveth not, knoweth not God; for God is love.” Here, manifestly, he has called that love God, which he said was of God; therefore God of God is love. …

52. Here some one will say, This is now not to write of virginity, but of humility. As though truly it were any kind of virginity, and not that which is after God, which we had undertaken to set forth. And this good, by how much I see it to be great, by so much I fear for it, lest it be lost, the thief pride. Therefore there is none that guardeth the virginal good, save God Himself Who gave it: and God is Charity. The Guardian therefore of virginity is Charity: but the place of this Guardian is humility. There forsooth He dwelleth, Who said, that on the lowly and quiet, and that trembleth at His words, His Spirit resteth. …

That love, however, which is a virtue, comes to us from God, not from ourselves, according to the testimony of Scripture, which says: “Love is of God; and every one that loveth is born of God, and knoweth God: for God is love.” It is on the principle of this love that one can best understand the passage, “Whosoever is born of God doth not commit sin;” as well as the sentence, “And he cannot sin.” Because the love according to which we are born of God “doth not behave itself unseemly,” and “thinketh no evil.” Therefore, whenever a man sins, it is not according to love: but it is according to cupidity that he commits sin; and following such a disposition, he is not born of God. Because, as it has been already stated, “the capacity” of which we speak is capable of either root. …

2. But why have we this that follows, “In my Father’s house are many mansions,” but that they were also in fear about themselves? And therein they might have heard the words, “Let not your heart be troubled.” For, was there any of them that could be free from fear, when Peter, the most confident and forward of them all, was told, “The cock shall not crow till thou hast denied me thrice”? Considering themselves, therefore, beginning with Peter, as destined to perish, they had cause to be troubled: but when they now hear, “In my Father’s house are many mansions: if it were not so, I would have told you; for I go to prepare a place for you,” they are revived from their trouble, made certain and confident that after all the perils of temptations they shall dwell with Christ in the presence of God. …

4. “We are of God.” Let us see why; see whether it be for any other thing than charity. “We are of God: he that knoweth God heareth us; he that is not of God heareth not us. Hereby know we the spirit of truth, and of error:” namely by this, that he that heareth us hath the spirit of truth; he that heareth not us, hath the spirit of error. Let us see what he adviseth, and let us choose rather to hear him advising in the spirit of truth, and not antichrists, not lovers of the world, not the world. If we are born of God, “beloved,” he goes on, see above from what: “We are of God: he that knoweth God heareth us; he that is not of God heareth not us. …

10. “If any man say, I love God.” What God? wherefore love we? “Because He first loved us,” and gave us to love. He loved us ungodly, to make us godly; loved us unrighteous, to make us righteous; loved us sick, to make us whole. Ask each several man; let him tell thee if he love God. He cries out, he confesses: I love , God knoweth. There is another question to be asked. “If any man say, I love God, and hateth his brother, he is a liar.” By what provest thou that he is a liar? Hear. “For he that loveth not his brother whom he seeth, how can he love God whom he seeth not?” What then? does he that loves a brother, love God also? He must of necessity love God, must of necessity love Him that is Love itself. Can one love his brother, and not love Love? Of necessity he must love Love. What then? because he loves Love, does it follow that he loves God? Certainly it does follow. …
