Chapter 4
[1 John 4:1] -- Beloved, do not believe every spirit, etc. And who is it that tests the spirits or how they can be tested, the Lord teaches in the Gospel where he foretold such things as John already proves came in his time. Beware, he said, of false prophets who come to you in sheep's clothing, but inwardly are ravenous wolves. You will know them by their fruits. Do they gather grapes from thorns, or figs from thistles (Matt. VII)? These are therefore the fruits by which evil spirits, who speak in false prophets, can be known—the thorns of schisms, and the rough thistles of heresies, by which they contaminate those who approach them incautiously, tearing their faith. Conversely, the fruits of the good, that is, love, joy, peace in the Holy Spirit, are aptly figured by the fragrance of the grapes and the sweetness of the figs.
[1 John 4:2] -- In this is known the Spirit of God, etc. Confession in this place is understood not only as the Catholic faith but also as the good operation which is done through charity. Otherwise, some heretics confess, many schismatics, many false Catholics, that Jesus Christ has come in the flesh, but they deny their confession by their deeds, not having charity. For charity brought the Son of God to the flesh. And therefore, whoever does not have charity denies that He has come in the flesh, such a one is convicted of not having the Spirit from God. But He is the Spirit of God, who says that Jesus Christ has come in the flesh, who says it not with the tongue, but with deeds, not by sounding, but by loving.
[1 John 4:3] -- And every spirit that dissolves Jesus is not from God. He dissolves Jesus who denies either His divinity, or His soul, or His flesh, which the Catholic faith teaches that He truly has. He also dissolves Jesus who, by perversely interpreting or by perverse sight, corrupts the commands and words of Jesus. But also he who disturbs the unity of the holy Church, which Jesus came to gather, strives, as far as is in him, to dissolve Jesus. Nor is it surprising if such are not from God, who disband the works, words, or sacraments of God. For they are so far from God, that some of them who wished by evil doctrine to separate the divinity of Christ from human dispensation, have also erased this verse, where it is said, "And every spirit that dissolves Jesus is not from God," from this Epistle, lest their error be convicted by the authority of blessed John. Finally, Nestorius revealed that he did not know this sentence was inserted into the authentic copies, and therefore he did not fear to dissolve Jesus, and thus render himself foreign to God, saying that the blessed Virgin Mary was not the mother of God, but only of a man, such that he made another person of the man, another of the Deity; nor did he believe in one Christ in the Word of God and in flesh and soul, but preached separately another Son of God, another of man.
[1 John 4:3] -- And this is the Antichrist of whom you have heard that he comes, etc. He comes with the imminent day of judgment, born into the world as that man more wicked than all others, the son of iniquity. And now he is already in the world, dwelling in the minds of those who resist Christ either by profession or by deed, without the remedy of repentance.
[1 John 4:4] -- You are from God, little children, and you have conquered him. You have conquered the Antichrist by confessing that Jesus Christ has come in the flesh, that is, by having the charity that Jesus Christ taught when he came in the flesh, which he also commends in the Gospel, saying: Greater love has no one than this, that someone lay down his life for his friends (John XV). For how could the Son of God lay down his life for us, unless he was clothed in flesh, where he could die? Therefore, anyone who violates charity, no matter what he says with his tongue, by his life denies that Christ has come in the flesh, and he himself is the Antichrist. And you have conquered him, he says. But how have they conquered? Was it by the power of free will? Certainly not. Let Pelagius be silent, let John himself speak:
[1 John 4:4] -- Because greater is he who is in you, etc. He thus teaches them to maintain humility, so that they do not attribute victory to their own strength, and are overcome by the arrogance of pride. He teaches them to always have confidence and hope of victory in the midst of adversities, retaining in their memory that the Lord is greater to protect than the devil to attack.
[1 John 4:5] -- They are from the world, etc. The Antichrists, that is, the heretics, even if they invoke the name of Christ or mark themselves with the sign of Christ, still they are from the world, that is, from the number of those who think worldly thoughts, who seek the lowly things, who are ignorant of celestial matters. And thus they speak of the world, namely by the reason of worldly wisdom opposing the Christian faith, saying that it cannot be that the Son of God is coeternal with the Father, that an untouched virgin gives birth, that flesh rises from dust, immortal, that a man brought forth from the earth perceives a dwelling in the heavens, that a newborn infant is held bound by the guilt of the first man unless reborn in Christ through the water of baptism is saved.
[1 John 4:5] -- And the world listens to them. For the hearts of the spiritual cannot be recalled to worldly and carnal senses from the simplicity of faith. But even the Catholics who, hearing that saying of the Lord: "Love your enemies, do good to those who hate you, and pray for those who persecute and calumniate you" (Matthew V); and again: "If you forgive men their trespasses, your heavenly Father will also forgive you; but if you do not forgive men, neither will your Father forgive your trespasses" (Matthew VI), say they cannot in any way leave their injuries unavenged: these indeed are proved to be of the world, and hence they speak of the world. And because they do not have the bowels of charity, they keep the inviolate mysteries of faith in vain. Nor can they be without the name of Antichrist, who are shown to be opposed to the commands of Christ.
[1 John 4:6] -- We are of God. He who knows God, etc. For the carnal man does not receive the things of the Spirit of God, for they are foolishness to him. Therefore, he who does not want to hear the preachers of charity is undoubtedly known not to know God, nor to be of God, because he has neglected to imitate the charity that God has exercised towards men.
[1 John 4:6] -- In this we know the Spirit of truth and the spirit of error. In this, indeed, because he who listens to us has the Spirit of truth; he who does not listen to us has the spirit of error. And this is the distinction of spirits, about which he warned above, saying: "Test the spirits to see whether they are of God." But let us see what he is about to admonish, in which we should hear him:
[1 John 4:7] -- Beloved, let us love one another, etc. He has highly recommended charity, which he said is from God; he is about to say more, let us listen attentively:
[1 John 4:7] -- And everyone who loves is born of God, etc. What more could be said? God is charity. Therefore, to act against charity is to act against God. Let no one say: I sin against man when I do not love my brother, and it is an easy sin against man, if I do not sin against God alone. How do you not sin against God, when you sin against charity? God is charity.
[1 John 4:9] -- In this God's love appeared in us, etc. As the Lord himself says: Greater love hath no man than this, that a man lay down his life for his friends (John XV); and thus the love of Christ for us is proven, because he died for us. The Father's love is also proven in us, because he sent his only Son to die for us. Thus also the Apostle Paul says: He that spared not his own Son, but delivered him up for us all, how shall he not also with him freely give us all things (Rom. VIII)?
[1 John 4:10] -- In this is love, etc. We did not love him first. For he loved us to the extent that we might love him. Grace indeed goes before man, that he may love God, by which love he works good things. Whence the Psalmist says: My God, his mercy shall anticipate me (Ps. LVIII).
[1 John 4:10] -- And he sent his Son to be the propitiation, etc. And this is the greatest sign of divine love for us, because when we did not yet know how to ask him for forgiveness for our sins, he sent his Son to us, who, to those believing in him, would grant pardon freely and call us to the fellowship of paternal glory. In some Codices, this verse is read thus: And he sent his Son to be the altar sacrifice for our sins. The altar sacrifice means a sacrificer. For the Son of God sacrificed for our sins not by offering cattle, but by offering himself. Hence Paul rightly admonishes, saying: Therefore be ye imitators of God, as beloved children, and walk in love, as Christ also loved us, and gave himself up for us an offering and a sacrifice to God for a sweet-smelling savor (Eph. V). In agreement with this is what John also here adds in exhortation, saying:
[1 John 4:11] -- Beloved, if God so loved us, etc. What then follows:
[1 John 4:12] -- No one has ever seen God. A greater discussion is needed, since the Lord promises that the pure in heart will see God, and He says of the saints that their angels always see the face of the Father in heaven. John also stated this in his Gospel, where he consequentially adds how God can be seen, saying: The only begotten Son, who is in the bosom of the Father, He has declared Him (John I). Blessed Father Ambrose explained it thus: "And no one has ever seen God, because the fullness of the divinity dwelling in God has been seen by no one, comprehended by neither mind nor eyes. For 'seeing' must be referred to both. Hence when it is added: The only begotten Son, who is in the bosom of the Father, He has declared Him, it is a vision of the mind rather than of the eyes being spoken of. The form is seen, the power is narrated. The former is comprehended by eyes, the latter by the mind." Likewise, blessed Augustine in his book on seeing God, discussing the same question: "Therefore (he says), with the only begotten, who is in the bosom of the Father, narrating with ineffable narration, a rational, pure, and holy creature is filled with the ineffable vision of God. We will achieve this when we have become equal to the angels, for we shall see face to face (I Cor. XIII). As visible things are seen by the senses of the body, no one has ever seen God: because if He was ever seen in any way, it was not as a natural object is seen, but He willed to be seen in the form He chose, with His nature remaining hidden and unchangeable in Himself. But in the way He is seen as He is (I Cor. XIII), perhaps He is now seen by some of His holy angels. But by us, He will be seen in that way when we shall have become equal to them." And after some propositions, expounding the sentence of Saint Ambrose, Augustine says, "No one has ever seen God, either in this life as He is, or even in the life of angels, as these visible things are perceived by bodily vision, because the only begotten Son who is in the bosom of the Father, He has declared Him. Therefore, it pertains not to the vision of bodily eyes, but to the vision of minds." And after these many words: "To that vision (he says) by which we will see God as He is (I Cor. XIII), He admonished pure hearts. Because, indeed, bodies are by customary speech called visible, thus God is called invisible so that He may not be believed to be a body. It does not mean that He would deprive pure hearts of the contemplation of His substance, since this great and highest reward is promised to those who honor and love God, as the Lord Himself said when He visibly appeared to bodily eyes, and He promised to show Himself invisibly to pure hearts: Whoever loves me will be loved by my Father, and I will love him and show myself to him (John XIV). For His nature is equally invisible with the Father, just as it is equally incorruptible. Paul listed these consecutively, saying: Now to the King eternal, immortal, invisible, he commended the divine substance in a manner he could to humans through preaching. Therefore, God is an invisible reality, to be sought not with the eye but the mind. But just as if we wanted to see the sun, we would purify the eye of the body from which light can be seen; so also, wanting to see God, let us purify the eye of the heart with which God can be seen: Blessed are the pure in heart, for they shall see God (Matthew V). But since this vision is hoped for in the future, what must we do now, while still in the body, wandering away from the Lord? What solace should we use when divine vision is not yet permitted to us?"
[1 John 4:12] -- If we love one another, God abides in us. But let no one think that this love, in which God abides, is preserved by a certain lax and lazy gentleness, indeed not by gentleness but by leniency and negligence. This is not charity, but languor; charity should burn fervently to amend and correct. But if morals are good, let them delight; if they are bad, let them be amended and corrected. Therefore, if we love one another with sincere and disciplined charity, God abides in us, manifested indeed by the works of that very charity, even though He does not yet appear visibly.
[1 John 4:12] -- And His charity is perfected in us. However, it must be inquired how he says that the perfection of divine charity consists in mutual love, since the Lord in the Gospel pronounces that it is not a great thing if we love those who love us, unless that same love extends also to enemies, about whom he here seems completely silent? Unless perhaps we should love even these enemies with the gaze of fraternal love, so that they do not always remain enemies, but repent from the snares of the devil and join us in a genuine covenant. If we love one another, he says, God abides in us, and His charity is perfected in us. Begin to love, you will be perfected. You have begun to love, God has begun to dwell in you, so that by dwelling more perfectly He may make you perfect.
[1 John 4:13] -- In this we know that we abide in Him, etc. This very thing, because He gave His Spirit to you, how do you know? Ask your own inner parts. If they are full of charity, you have the Spirit of God, as Paul attests, who says: Because the charity of God is poured out in our hearts by the Holy Spirit who is given to us (Rom. V).
[1 John 4:14] -- And we have seen and testify, etc. Let no one despair of salvation, because although the diseases of crimes that weigh one down are great, the omnipotent physician has come to save. Yet let each remember that the same Son of God who came gently to save, will come sternly to judge.
[1 John 4:15] -- Whoever confesses that Jesus is the Son of God, etc. He speaks of the perfect confession of the heart, which can neither be corrupted by the deceit of heretics who wrongly persuade, nor be shattered by the tortures of pagan persecutors, nor falter by the examples of fleshly brothers, nor waver by the sluggishness of one's own weakness. For there are those who even deny by words that Jesus is the Son of God, of which many are reported to have been at that very time when John wrote this. Likewise, there are those who confess in words, but deny in actions. Hence it is well stated now: Whoever confesses that Jesus is the Son of God, God abides in him, and he in God, he said a little above: If we love one another, God abides in us, surely insinuating that whoever has love for his brothers, he truly testifies that Jesus is the Son of God.
[1 John 4:16] -- And we have known and believed the love that God has in us. We have known that Jesus is the Son of God, and that the Father sent him as the Savior of the world. And we believe the love that God has in us, because evidently when He had His only Son, He did not want Him to be alone, but so that He might have brothers, He adopted those who would possess eternal life with Him.
[1 John 4:16] -- God is love. He already said that above, behold he says it again. Love could not be commended to you more than by saying God. Perhaps you were going to scorn the gift of God: will you scorn God as well?
[1 John 4:16] -- And he who abides in love, abides in God, and God in him. Conversely, those who contain and those who are contained live in each other. You dwell in God, but so that you may be contained; God dwells in you, but so that He may contain you lest you fall, because as the Apostle says of love itself: Charity never fails. How does he fall whom God contains?
[1 John 4:17] -- In this, love is perfected with us, etc. He says how each one may test how much he has progressed in love. Whoever has confidence on the day of judgment, love is perfected in him. What is it to have confidence on the day of judgment? It is to not fear the coming of the day of judgment. For when someone first converts himself from wicked deeds by repenting, he begins to fear the day of judgment, lest, namely, when the Just Judge appears, he himself, being unjust, be condemned. However, encouraged by a good life in the process, he learns not to fear what he once feared, but rather to wish for the coming of the awaited one for all nations, hoping that he will be crowned with the saints by the merit of good actions. From where we can have confidence on the day of judgment, he explains more fully by adding:
[1 John 4:17] -- Because as He is, so are we in this world. Can a man indeed be as God? But it should be remembered what was said above, that “as” does not always refer to equality, but it refers to a certain similarity. For when you say, "As I have ears, so too does the image," is it entirely so? Yet still you say "as." So if we are made in the image of God, why are we not as God? Not in equality, but in our own measure. Therefore, confidence is given to us on the day of judgment, because as He is, so are we in this world—namely by imitating the perfection of love in the world, of which He daily provides us an example from heaven. Concerning this, the Savior in the Gospel says, "Love your enemies, and pray for those who persecute you and slander you, so that you may be children of your Father who is in heaven, who makes His sun rise on the good and the bad, and rains on the just and the unjust" (Matthew 5).
[1 John 4:18] -- There is no fear in love. In that particular love which, in imitation of divine goodness, knows how to do good even to enemies and to love them.
[1 John 4:18] -- But perfect love casts out fear. This fear, of course, of which it is said: The fear of the Lord is the beginning of wisdom (Psalm CX). By which anyone fearing begins works of justice, lest the strict Judge come, and finding himself less chastened, be condemned. This fear is cast out by the love which, on account of its merit of justice, has confidence on the day of judgment. But also the fear of present adversities, perfect love expels from the soul. The one who supplicates to the Lord sought to have, saying: Deliver my soul from the fear of the enemy (Psalm LXIII). The one who had it said: Who shall separate us from the love of Christ? Shall tribulation, or distress, or persecution, or famine, or nakedness, or peril, or sword? etc. (Romans VIII).
[1 John 4:18] -- Because fear has torment. The heart is tormented by the conscience of sins, because justification has not yet been made. Therefore, in the Psalm, concerning this very perfection of justice, "You have turned (he says) my mourning into joy for me; you have removed my sackcloth, and girded me with gladness, that my glory may sing praise to you, and not be silent" (Psalm XXIX), that is, there may not be anything to pierce my conscience. Fear pierces, but do not be afraid: love enters, which heals what fear wounds.
[1 John 4:18] -- But whoever fears is not perfect in charity. Because clearly fear has punishment, as a doctor’s surgery has punishment; although just as the doctor’s surgery brings hoped-for health, so fear follows desired charity. Nor should it be thought that the words of Blessed John are contrary to what the Psalmist says: "The fear of the Lord is holy, enduring forever and ever" (Psalm 19). For there are two fears: one by which men fear God lest they be cast into hell; this is the fear that introduces charity, but it comes so that it may go out. For if you still fear God because of punishments, you do not yet love whom you thus fear; you do not desire good things, but you avoid bad ones; but because you avoid bad things, you correct yourself, and begin to desire good things. When you begin to desire good things, that holy fear will be in you, namely lest you lose those good things, not so that you may not be cast into hell, but lest the presence of the Lord whom you embrace may desert you, whom you wish to enjoy forever.
[1 John 4:19] -- Therefore, let us love God, etc. Let us love because He first loved us. For how could we love unless He had first loved us? Hence He Himself says in the Gospel: “You did not choose me, but I chose you” (John 15). Thus, we will be perfect in charity if, just as He first loved us for the sake of our own salvation, so we also love Him solely for the sake of love. But because there are those who love God only in words, it is wisely added:
[1 John 4:20] -- If anyone says, ‘I love God,’ etc. How do you prove that he is a liar? Listen:
[1 John 4:20] -- For he who does not love his brother, etc. He who loves his brother loves God. It is necessary to love God in order to love love itself. For God is love. And lest anyone dare to say: "And what does it hinder to love God, even if I do not love my brother?" it is rightly added:
[1 John 4:21] -- And this commandment we have from God, etc. For how can you love him whose command you hate? Who is it who says: I love the emperor, but I hate his laws? Not so the true lover of God, but: See (he says) that I have loved your commands, O Lord (Psalm CXVIII). And therefore he confidently adds: Quicken me in your mercy (Ibid.).
