Andreas of Caesarea : This was the heresy of Simon, which said that Jesus and the Christ were two different people. According to them, Jesus was a man, the son of Mary, but Christ descended from heaven in the form of a dove at the Jordan. John therefore condemns those who think like that and brands their belief with the name of the devil. There were still others who made a distinction between the Father and some nameless deity beyond him, whom they called the Father of Christ. These too denied Jesus, saying that he was a mere man and did not have the nature of God. — CATENA Augustine of Hippo : Let us see then how antichrists lie, because there is more than one kind of lying. "Who is a liar, but he that denieth that Jesus is the Christ?" One is the meaning of the word "Jesus," another the meaning of the word "Christ:" though it be one Jesus Christ our Saviour, yet "Jesus" is His proper name. Just as Moses was so called by his proper name, as Elias, as Abraham: so as His proper name our Lord hath the name "Jesus:" but "Christ" is the name of His sacred character. As when we say, Prophet, as when we say, Priest; so by the name Christ we are given to understand the Anointed, in whom should be the redemption of the whole people. The coming of this Christ was hoped for by the people of the Jews: and because He came in lowliness, He was not acknowledged; because the stone was small, they stumbled at it and were broken. But "the stone grew, and became a great mountain;" and what saith the Scripture? "Whosoever shall stumble at this stone shall be broken; and on whomsoever this stone shall come, it will grind him to powder." We must mark the difference of the words: it saith, he that stumbleth shall be broken; but he on whom it shall come, shall be ground to powder. At the first, because He came lowly, men stumbled at Him: because He shall come lofty to judgment, on whomsoever He shall come, He will grind him to powder. But not that man will He grind to powder at His future coming, whom He broke not when He came. He that stumbled not at the lowly, shall not dread the lofty. Briefly ye have heard it, brethren: he that stumbled not at the lowly, shall not dread the lofty. For to all bad men is Christ a stone of stumbling; whatever Christ saith is bitter to them. — Ten Homilies on 1 John 3 Augustine of Hippo : And how are they proved to be antichrists? By lying. "And who is a liar, but he that denieth that Jesus is the Christ?" Let us ask the heretics: where do you find a heretic that denies that Jesus is the Christ? See now, my beloved, a great mystery. Mark what the Lord God may have inspired us withal, and what I would fain work into your minds. Behold, they went out from us, and turned Donatists: we ask them whether Jesus be the Christ; they instantly confess that Jesus is the Christ. If then that person is an antichrist, who denies that Jesus is the Christ, neither can they call us antichrists, nor we them; therefore, neither they went out from us, nor we from them. If then we have not gone out one from another, we are in unity: if we be in unity, what means it that there are two altars in this city? what, that there are divided houses, divided marriages? that there is a common bed, and a divided Christ? — Ten Homilies on 1 John 3 Augustine of Hippo : For if all be asked, all with one mouth confess that Jesus is the Christ. Let the tongue keep still for a little while, ask the life. If we shall find this, if the Scripture itself shall tell us that denial is a thing done not only with the tongue, but also with the deeds, then assuredly we find many antichrists, who with the mouth profess Christ, and in their manners dissent from Christ. Where find we this in Scripture? Hear Paul the Apostle; speaking of such, he saith, "For they confess that they know God, but in their deeds deny Him." We find these also to be antichrists: whosoever in his deeds denies Christ, is an antichrist. I listen not to what he says, but I look what life he leads. Works speak, and do we require words? For where is the bad man that does not wish to talk well? But what saith the Lord to such? "Ye hypocrites, how can ye speak good things, while ye are evil?" Your voices ye bring into mine ears: I look into your thoughts. I see an evil will there, and ye make a show of false fruits. I know what I must gather, and whence; I do not "gather figs of thistles," I do not gather "grapes of thorns;" for "every tree is known by its fruit." A more lying antichrist is he who with his mouth professes that Jesus is the Christ, and with his deeds denies Him. A liar in this, that he speaks one thing, and does another. — Ten Homilies on 1 John 3 Augustine of Hippo : Now therefore, brethren, if deeds are to be questioned, not only do we find many antichrists gone out; but many not yet manifest, who have not gone out at all. For as many as the Church hath within it that are perjured, defrauders, addicted to black arts, consulters of fortune-tellers, adulterers, drunkards, usurers, boy-stealers, and all the other vices that we are not able to enumerate; these things are contrary to the doctrine of Christ, are contrary to the word of God. Now the Word of God is Christ: whatever is contrary to the Word of God is in Antichrist. For Antichrist means, "contrary to Christ." And would ye know how openly these resist Christ? Sometimes it happens that they do some evil, and one begins to reprove them; because they dare not blaspheme Christ, they blaspheme His ministers by whom they are reproved: but if thou show them that thou speakest Christ's words, not thine own, they endeavor all they can to convict thee of speaking thine own words, not Christ's: if however it is manifest that thou speakest Christ's words, they go even against Christ, they begin to find fault with Christ: "How," say they, "and why did He make us such as we are?" Do not persons say this every day, when they are convicted of their deeds? Perverted by a depraved will, they accuse their Maker. — Ten Homilies on 1 John 3 Bede : Who is the liar, if not he who denies that Jesus is the Christ? He had foretold that every lie is not from the truth, but since there are many kinds of lies that are not at all similar, now he sets forth the lie of denial of Christ as singular because this is such a heinous and abominable lie that in comparison to it, other lies either seem small or nonexistent. According to what was said to the sinning Jerusalem: Sodom was justified because of you (Ezekiel 16). This denial is proper to the Jews, that they say Jesus is not the Christ. But even heretics who wrongly believe about Christ deny Jesus is the Christ, because they do not think rightly about Christ; nor do they confess him as such as divine truth teaches, but as their vanity invents. Wicked Catholics also who despise obeying the commands of Christ deny Jesus is the Christ, to whom they do not render the due service of fear or love as to the Son of God but dare to contradict at their will as to a man of no power. Therefore, all these are proved to be liars and Antichrists, that is, contrary to Christ, as the Apostle attests who says: They profess to know God, but they deny him by their deeds (Titus 1). — Commentary on the Catholic Epistles Bede : This is the Antichrist, he who denies the Father and the Son. With this sentence, he strikes both heretics and especially the Jews, who denying that Jesus is the Son of God, nonetheless claimed to have God as the Father, showing them to confess the Father in vain if they deny the Son. Hence, the Lord himself, cursing them, said: If God were your Father, you would love me, for I came from God and am here (John 8). — Commentary on the Catholic Epistles Clement of Alexandria ((as quoted by Cassiodorus)) : "A liar" and "an antichrist, who denies that Jesus is the Christ." For Jesus, Saviour and Redeemer, is also Christ the King. — From the Latin Translation of Cassiodorus Ignatius of Antioch : Whosoever, therefore, declares that there is but one God, only so as to take away the divinity of Christ, is a devil, and an enemy of all righteousness. He also that confesseth Christ, yet not as the Son of the Maker of the world, but of some other unknown being, different from Him whom the law and the prophets have proclaimed, this man is an instrument of the devil. And he that rejects the incarnation, and is ashamed of the cross for which I am in bonds, this man is antichrist. Moreover, he who affirms Christ to be a mere man is accursed, according to the [declaration of the] prophet, since he puts not his trust in God, but in man. Wherefore also he is unfruitful, like the wild myrtle-tree. — Epistle of Pseudo-Ignatius to the Antiochians Oecumenius : "Who is the liar, except for the one who denies that Jesus is the Christ? This is the Antichrist who denies the Father and the Son." Here too, we must hear the conjunction καὶ, that is, "and", for the sake of clearer understanding, so that the sense is this: And who is the liar, except for the one who denies that Jesus is the Christ? But the wicked Simon was raving, claiming that there was one Jesus and another Christ: the Jesus who was born of the holy Mary; but the Christ who descended from heaven into the Jordan. Therefore, he who applauds this lie, John says, is the Antichrist. This, however: This is the Antichrist, must be understood in two ways, both regarding the one who denies that Jesus is the Christ, and regarding the one who denies the Father and the Son. For he, John says, who denies the Father and the Son, is also a liar and an antichrist. — Commentary on 1 John Tertullian : John, moreover, brands that man as "a liar" who "denieth that Jesus is the Christ; "whilst on the other hand he declares that "every one is born of God who believeth that Jesus is the Christ." Wherefore he also exhorts us to believe in the name of His (the Father's, ) Son Jesus Christ, that "our fellowship may be with the Father, and with His Son Jesus Christ. — Against Praxeas
