Overcoming the World 1 Whoever believes that Jesus is the Christ is born of God: and every one that loves him that fathered loves him also that is begotten of him.
Irenaeus · AD 202 All, therefore, are outside of the [Christian] dispensation, who, under pretext of knowledge, understand that Jesus was one, and Christ another, and the Only-begotten another, from whom again is the Word, and that the Saviour is another, whom these disciples of error allege to be a production of those who were made Aeons in a state of degeneracy.
Caesarius of Arles · AD 542 John immediately joined love to faith, because without love faith is useless. According to charity, faith belongs to Christians, but without love it belongs to the demons. Moreover, those who do not believe are even worse than the demons.
Theophylact of Ohrid · AD 1107 And this is said in confirmation of the above. If we received from the Teacher the commandment to love one another, then, without a doubt, if we believe that our Teacher Jesus is the Christ, and He is the Christ in the sense that He is God and man together, we must also keep His commandments, as those of a Teacher and as those of God.
2 By this we know that we love the children of God, when we love God, and keep his commandments.
Augustine of Hippo · AD 430 Behold, sayest thou, I love the Father, and I love the Son: but this only, the Father God and the Son God, our Lord Jesus Christ, who ascended into heaven, and sitteth at the right hand of the Father, that Word by which all things were made, and "the Word was made flesh, and dwelt in us:" this alone I love.
Oecumenius · AD 550 By this we know that we love the children of God, when we love God and keep his commandments. And John adds this persuasion: that whoever loves the one who created him loves also the one who is born of him. Then he uses a change of discourse and says that love for brothers or the children of God confirms love for Him who created.
Bede · AD 735 In this we know that we love the children of God, etc. Therefore, he alone is proven to love his neighbor rightly who is known to burn with the love of the Creator.
3 For this is the love of God, that we keep his commandments: and his commandments are not grievous.
Clement of Alexandria · AD 215 And if we are called to the kingdom of God, let us walk worthy of the kingdom, loving God and our neighbour. But love is not proved by a kiss, but by kindly feeling. But there are those, that do nothing but make the churches resound with a kiss, not having love itself within.
Andreas of Caesarea · AD 614 Keeping the commandments is both the form and substance of our love for God. Those who obey them are brought close to God by them. If someone looks at them in the wrong way and says that they are heavy to bear, he is merely revealing his own weakness.
Bonaventure · AD 1257 The commandments of God are irreproachable, because they contain nothing impossible: whence in First John: "This is the love of God, that we keep his commandments, and his commandments are not burdensome." He premises: "this is the love of God": for to one having charity the commandments of God are easy and sweet, but to one not having charity they seem difficult.
4 For whatever is born of God overcomes the world: and this is the victory that overcomes the world, even our faith.
Cyril of Alexandria · AD 444 Neither a Jew nor a pagan nor a heretic can do anything in the face of this victory which is ours through faith.
Andreas of Caesarea · AD 614 This means that such a person has overcome all evil and ungodliness. For our faith has destroyed all ignorance and driven out all darkness.
Bede · AD 735 And this is the victory that overcomes the world: our faith. Specifically, that faith which works through love; that faith by which we humbly seek the help of Him who said: In the world you will have tribulations, but take courage, I have overcome the world (John 16).
5 Who is he that overcomes the world, but he that believes that Jesus is the Son of God?
Oecumenius · AD 550 Who is it that overcomes the world except the one who believes that Jesus is the Son of God? And since faith does not conquer alone, but together with the one who possesses it, John adds: "And who is it that overcomes the world, except the one who believes that Jesus is the Son of God?" But who is this Jesus? "He who came by water and blood, Jesus Christ". (1 Jn. 5:6)
Bede · AD 735 Who is he that overcomes the world, etc.? He overcomes the world who, believing that Jesus is the Son of God, combines works worthy of that faith. But does the faith and confession of His divinity alone suffice for salvation? See what follows.
6 This is he that came by water and blood, even Jesus Christ; not by water only, but by water and blood. And it is the Spirit that bears witness, because the Spirit is truth.
Irenaeus · AD 202 Moreover, how could the Lord, with any justice, if He belonged to another father, have acknowledged the bread to be His body, while He took it from that creation to which we belong, and affirmed the mixed cup to be His blood? And why did He acknowledge Himself to be the Son of man, if He had not gone through that birth which belongs to a human being?
Andreas of Caesarea · AD 614 What flowed from his side was also the blood which cleanses us from sin and sanctifies the people of God.… It was not a mere man who appeared at the Jordan but the incarnate Word of God, to whom the Father also bore witness: "This is my beloved Son in whom I am well pleased." Similarly, when he was hanging on the cross, what sounded to the people like thunder was the voice of G…
Bonaventure · AD 1257 The third firmness of faith is that which proceeds from the witness of truth as expressed through the inspired word: and this occurred with all the prophets. And we have heard this Word, for it is the Spirit that bears witness that Christ is the truth. Some have actually seen Him in the flesh.
7 For there are three that bear record in heaven, the Father, the Word, and the Holy Spirit: and these three are one.
Cyprian · AD 258 The Lord says, "I and the Father are one;" and again it is written of the Father, and of the Son, and of the Holy Spirit, "And these three are one." And does any one believe that this unity which thus comes from the divine strength and coheres in celestial sacraments, can be divided in the Church, and can be separated by the parting asunder of opposing wills?
Bede · AD 735 Since there are three who bear witness on earth, etc. The Spirit has borne witness that Jesus is truth, when it descended upon Him at His baptism. For if he were not truly the Son of God, by no means would the Holy Spirit have come to Him with such a great manifestation.
Bonaventure · AD 1257 1 John 5: Three are they who give testimony in heaven, the Father, the Word, and the Holy Spirit, and these three are one; I say one absolutely, which I say with no addition: therefore they are one absolutely: therefore the trinity does not take away unity.
8 And there are three that bear witness in earth, the spirit, and the water, and the blood: and these three agree in one.
Augustine of Hippo · AD 430 Three things then we know to have issued from the Body of the Lord when He hung upon the tree: first, the spirit: of which it is written, "And He bowed the head and gave up the spirit:" then, as His side was pierced by the spear, "blood and water." Which three things if we look at as they are in themselves, they are in substance several and distinct, and therefore they are not…
Oecumenius · AD 550 For there are three that bear witness: the Spirit, the water, and the blood; and these three are one. Therefore, since three bear witness to Jesus' adoption, namely baptism, crucifixion, and resurrection, there is no uncertainty in the Lord's adoption: by which adoption He also granted us, as He who was the first fruits of the entire human mass (Rom.
Bonaventure · AD 1257 The incarnation cannot be known unless one is aware of the distinction of Persons. For if you do not know the Trinity, the Father could have been incarnated and have suffered as well as the Son: and this is Sabellianism and Patripassianism. Likewise, if you suppose the Trinity and not the incarnation, you have a witnessing in heaven, but you do not receive it on earth.
God’s Testimony about His Son 9 If we receive the witness of men, the witness of God is greater: for this is the witness of God which he has testified of his Son.
Hilary of Arles · AD 449 The testimony of men refers to the testimony of people like Moses and the prophets, who were all men of God.
Bede · AD 735 If we accept the testimony of man, the testimony of God is greater, etc. Great is the testimony of man that he gives concerning the Son of God, saying: "The Lord said to my Lord: Sit at my right hand" (Psalm 109). And from the person of the Son himself: "The Lord said to me: You are my Son" (Psalm 2).
Theophylact of Ohrid · AD 1107 Having said this, he confirms his words with a proof from the lesser. If we accept human testimony about something, should we not all the more justly accept the greater testimony, from God? For this testimony about the Son of God, that is Christ, is it not from God Himself?
10 He that believes on the Son of God has the witness in himself: he that believes not God has made him a liar; because he believes not the record that God gave of his Son.
Hilary of Arles · AD 449 God can never turn himself into a liar, because he is the essence of truth. But an unbelieving man is a liar, because he does not believe in the truth of God.
Andreas of Caesarea · AD 614 After giving us one testimony about his Son, God gave us another, which is eternal life.
Bede · AD 735 He who believes in the Son of God has the testimony of God in himself. He who thus believes in the Son of God, so as to practice in work what he believes, has the testimony of God in himself.
11 And this is the record, that God has given to us eternal life, and this life is in his Son.
Shepherd of Hermas · AD 160 Accordingly, those also who fell asleep received the seal of the Son of God. For before a man bears the name of the Son of God he is dead; but when he receives the seal he lays aside his deadness, and obtains life. The seal, then, is the water: they descend into the water dead, and they arise alive.
Bede · AD 735 And this is the testimony, that God has given us eternal life. He said, He has given us eternal life. And he who speaks, still living a temporal life and subject to death in the flesh. But he has given us eternal life, just as he has given us the power to become children of God to those who believe in his name.
12 He that has the Son has life; and he that has not the Son of God has not life.
Tertullian · AD 220 We believe not the testimony of God in which He testifies to us of His Son. "He that hath not the Son, hath not life." And that man has not the Son, who believes Him to be any other than the Son.
Oecumenius · AD 550 He who has the Son has life; he who does not have the Son of God does not have life. Therefore, whoever has the Son through holy baptism has life. For as many as we have been baptized into Christ, we have also, according to His command, put on Christ. But whoever does not have the Son of God through baptism does not have life, but is dead.
Bede · AD 735 He who has the Son, has life, etc. So that it may not seem too little to say that life is in the Son, he added that the Son Himself is life. Which the Son, glorifying the Father, also showed when He said: For as the Father has life in Himself, so He has granted the Son to have life in Himself (John V).
Effective Prayer 13 These things have I written to you that believe on the name of the Son of God; that you may know that you have eternal life, and that you may believe on the name of the Son of God.
Oecumenius · AD 550 I have written these things to you who believe in the name of the Son of God: that you may know that you have eternal life, and that you may believe in the name of the Son of God.
Bede · AD 735 These things I have written to you, that you may know that you have eternal life, etc. That you may know, he says, that you may be certain of your future blessedness, who believe in Christ, so that you are not deceived by the fraud of those who deny that Jesus is the Son of God, and therefore assert that nothing will benefit those who have believed in His name.
Theophylact of Ohrid · AD 1107 Here a kind of conclusion is drawn. I have written this to you, he says, as heirs of eternal life. For to those who do not live according to the hope of eternal life, this could not have been written, because to give what is holy to dogs and to cast pearls before swine is not praiseworthy (Matt. 7:6).
14 And this is the confidence that we have in him, that, if we ask anything according to his will, he hears us:
Clement of Alexandria · AD 215 "And this is the confidence which we have towards Him, that if we ask anything according to His will, He will hear us." He does not say absolutely what we shall ask, but what we ought to ask.
Oecumenius · AD 550 And this is the confidence that we have in Him, that if we ask anything according to His will, He hears us. And if we know that He hears us in whatever we ask, we know that we have the requests that we have asked of Him. Then, since there is no other sign of this unquestionable faith except trust, which we find in Him through irreproachable faith, as we have also said before.
Theophylact of Ohrid · AD 1107 Then he says that the sign of this undoubted faith is none other than the boldness which we find before Him through blameless faith, as we also said above, and that in turn the sign of such boldness is the obtaining of everything we ask.
15 And if we know that he hear us, whatever we ask, we know that we have the petitions that we desired of him.
Bede · AD 735 And we know that he hears us in whatever we ask, etc. He repeatedly emphasizes the same points previously stated, to encourage us to pray more energetically. But the objection remains that we should ask according to the will of our Creator.
16 If any man see his brother sin a sin which is not to death, he shall ask, and he shall give him life for them that sin not to death. There is a sin to death: I do not say that he shall pray for it.
Clement of Alexandria · AD 215 John, too, manifestly teaches the differences of sins, in his larger Epistle, in these words: "If any man see his brother sin a sin that is not unto death, he shall ask, and he shall give him life: for these that sin not unto death," he says. For "there is a sin unto death: I do not say that one is to pray for it. All unrighteousness is sin; and there is a sin not unto death."
Augustine of Hippo · AD 430 But what presses harder upon the present question is that saying of the apostle John, "If any man know that his brother sinneth a sin not unto death, he shall ask, and the Lord will give life to that man who sinneth not unto death: but there is a sin unto death: not for that do I say that he should ask." For it manifestly shows that there are some "brethren" whom we are not com…
Theophylact of Ohrid · AD 1107 Having said that God fulfills our requests that are in accordance with His will, the apostle now clearly expresses his desire concerning what we should ask for according to God's will.
17 All unrighteousness is sin: and there is a sin not to death.
Bede · AD 735 All iniquity is sin, etc. Such is the diversity of sins, he says, that everything which deviates from the rule of equity is counted among the sins, although small sins cannot in any way take away or diminish the merit of righteousness from the just, as long as they are those without which this life cannot be lived, and likewise there are certain sins so discordant with all just…
The True God 18 We know that whoever is born of God sins not; but he that is begotten of God keeps himself, and that wicked one touches him not.
Tertullian · AD 220 Chapter V.-Sin Never to Be Returned to After Repentance.
Andreas of Caesarea · AD 614 It may be true that the righteous person does not sin, but no one is a child of God by nature. This is why we avoid sin, not by the way in which we were made, which would make sin impossible for us, but by watching out that we do not fall into it.
Theophylact of Ohrid · AD 1107 Having taught us which sin is unto death and which is not unto death, he then indicates who can sin unto death, and says: one adopted by God can never be afflicted by sin, whether unto death or not unto death. For having once surrendered himself to Christ, who dwells in him through adoption, he remains untouchable by sin.
19 And we know that we are of God, and the whole world lies in wickedness.
Clement of Alexandria · AD 215 "And the whole word lies in the wicked one;" not the creation, but worldly men, and those who live according to their lusts.
Jerome · AD 420 [Daniel 4:4] "I, Nebuchadnezzar, was at ease in my house and prospering in my palace." The narrative is clear indeed and requires but little interpretation.
Bonaventure · AD 1257 The fifth middle way is kindness, either in the form of the re-establishment of justice or in that of friendship, which has nothing of malice, but through which a man seeks someone else's good; and here it is necessary that reason be guided.
20 And we know that the Son of God has come, and has given us an understanding, that we may know him that is true, and we are in him that is true, even in his Son Jesus Christ. This is the true God, and eternal life.
Clement of Alexandria · AD 215 "And the Son of God has come and given us understanding," which comes to us, that is, by faith, and is also called the Holy Spirit.
Oecumenius · AD 550 And we know that the Son of God has come and has given us an understanding, that we may know Him who is true; and we are in Him who is true, in His Son Jesus Christ. This is the true God and eternal life.
Bede · AD 735 This is the true God, and eternal life. He had said that the Son is the true God, and repeatedly affirms that this one is the true God. He says that this one is eternal life.
21 Little children, keep yourselves from idols. Amen.
Tertullian · AD 220 John did not tell us to keep away from worship, but from idols, that is, from their very likeness. For it is wrong for you, who are created in the image of the living God, to become the image of an idol and a dead man.
Oecumenius · AD 550 Little children, keep yourselves from idols. Amen. "keep yourself from idols." Some have questioned: If John writes this to the perfect, why does he now command them to beware of idols? We therefore say that because he wrote to the whole Church, which was not made up of a select people, but there were also some among them who were less affected.
Theophylact of Ohrid · AD 1107 Since the apostle wrote this epistle to mature believers, some asked why he commands them to keep themselves from idols. We answer: the apostle wrote this to the entire Church, which was not entirely filled with chosen people, but among them some were also of wrong disposition. To such people he gives this commandment, fearing for their weakness.
