1 John 4:20
If any man say, I love God, and hateth his brother; he is a liar. For he that loveth not his brother, whom he seeth, how can he love God, whom he seeth not?

- Vulgate (Clementine)
- Si quis dixerit : Quoniam diligo Deum, et fratrem suum oderit, mendax est. Qui enim non diligit fratrem suum quem vidit, Deum, quem non vidit, quomodo potest diligere ?
- Greek New Testament (SBLGNT)
- ἐάν τις εἴπῃ ὅτι Ἀγαπῶ τὸν θεόν, καὶ τὸν ἀδελφὸν αὐτοῦ μισῇ, ψεύστης ἐστίν· ὁ γὰρ μὴ ἀγαπῶν τὸν ἀδελφὸν αὐτοῦ ὃν ἑώρακεν, τὸν θεὸν ὃν οὐχ ἑώρακεν οὐ δύναται ἀγαπᾶν.
Haydock's commentary
He that loveth not his brother, whom he seeth, how can he love God, whom he seeth not? By this is signified, that it is more easy and natural to love the things that we see, and that enter by the senses. Pretend not then to love the invisible God, whose perfections are hidden from you in this life, unless you love your brother whom you see. But he adds another reason to prove that no man can love God unless he love his brother; because saith he, (ver. 21.) this is God's express command, that he who loveth God love also his brother: so that a man cannot love God unless he also love his neighbour.

The Fathers on this verse
St Cyprian Three Books of Testimonies Against the Jews, Testimony III
In Malachi: “Hath not one God created us? Is there not one Father of us all? Why have ye certainly deserted every one his brother?” Of this same thing according to John: “Peace I leave with you, my peace I give unto you.” Also in the same place: “This is my commandment, That ye love one another, even as I have loved you. Greater love than this has no man, than that one should lay down his life for his friends.” Also in the same place: “Blessed are the peacemakers, for they shall be called the sons of God.” Also in the same place: “Verily I say unto you, That if two of you shall agree on earth concerning everything, whatever you shall ask it shall be given you from my Father which is in heaven. …
St Augustine On the Holy Trinity, That He Who Loves His Brother, Loves God; Because He Loves Love Itself, Which is of God, and is God
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. …
St Augustine Lectures or Tractates on the Gospel According to St. John, Chapter IV. 1-18
8. How, then, do we find the two precepts of love indicated in these two commands of the Lord? “Take up thy bed,” saith He, “and walk.” What the two precepts are, my brethren, recollect with me. For they ought to be thoroughly familiar to you, and not merely to come into your mind when they are recited by us, but they ought never to be blotted out from your hearts. Let it ever be your supreme thought, that you must love God and your neighbor: “God with all thy heart, and with all thy soul, and with all thy mind; and thy neighbor as thyself.” These must always be pondered, meditated, retained, practised, and fulfilled. The love of God comes first in the order of enjoying; but in the order of doing, the love of our neighbor comes first. For He who commanded thee this love in two precepts did not charge thee to love thy neighbor first, and then God, but first God, afterwards thy neighbor. …
St Augustine Ten Homilies on the First Epistle of John, 1 John IV. 17-21
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. …
St Augustine Ten Homilies on the First Epistle of John, 1 John IV. 17-21
11. “For he that loveth not his brother whom he seeth, how can he love God whom he seeth not? And this commandment have we from Him, that he who loveth God love his brother also.” Marvellous fine talk it was, that thou didst say, “I love God,” and hatest thy brother! O murderer, how lovest thou God? Hast thou not heard above in this very epistle, “He that hateth his brother is a murderer”? Yea, but I do verily love God, however I hate my brother. Thou dost verily not love God, if thou hate thy brother. And now I make it good by another proof. This same apostle hath said, “He gave us commandment that we should love one another.” How canst thou be said to love Him whose commandment thou hatest? Who shall say, I love the emperor, but I hate his laws? In this the emperor understands whether thou love him, that his laws be observed throughout the provinces. …
St Augustine Ten Homilies on the First Epistle of John, 1 John V. 1-3
1. I Suppose ye remember, those of you who were present yesterday, to what place in the course of this epistle our exposition has reached: namely, “He that loveth not his brother whom he seeth, how can he love God whom he seeth not? And this commandment have we from Him, That he who loveth God, love his brother also.” Thus far we discoursed. Let us see then what comes next in order. “Whosoever believeth that Jesus is the Christ is born of God.” Who is he that believeth not that Jesus is the Christ? He that does not so live as Christ commanded. For many say, “I believe:” but faith without works saveth not. Now the work of faith is Love, as Paul the apostle saith, “And faith which worketh by love.” Thy past works indeed, before thou didst believe, were either none, or if they seemed good, were nothing worth. …
St Augustine Ten Homilies on the First Epistle of John, 1 John V. 1-3
3. “In this we know that we love the sons of God.” What is this, brethren? Just now he was speaking of the Son of God, not of sons of God: lo, here one Christ was set before us to contemplate, and we were told, “Whosoever believeth that Jesus is the Christ is born of God: and every one that loveth Him that begat,” i.e. the Father, “loveth Him also that is begotten of Him,” i.e. the Son, our Lord Jesus Christ. And he goes on: “In this we know that we love the sons of God;” as if he had been about to say, “In this we know that we love the Son of God.” He has said, “the sons of God,” whereas he was speaking just before of the Son of God, because the sons of God are the Body of the Only Son of God, and when He is the Head, we the members, it is one Son of God. …
