Andreas of Caesarea : John says this because there were some people who had become teachers but had subsequently departed from the truth in order to follow the blasphemies of their own minds. But even if they were once among us, John adds, they were never really part of us, since if they had been, they would have stayed with us. — CATENA Augustine of Hippo : It seems to us that all who appear to be good and faithful ought to receive the gift of final perseverance. God, however, has judged it better to mingle some who will not persevere with the certain number of his saints, so that those for whom security in the temptations of this life is not helpful cannot be secure. — ON THE GIFT OF PERSEVERANCE 8.19 Augustine of Hippo : Whom has he called antichrists? He goes on and expounds. "Whereby we know that it is the last hour," By what? Because "many antichrists are come. They went out from us;" see the antichrists! "They went out from us:" therefore we bewail the loss. Hear the consolation. "But they were not of us." All heretics, all schismatics went out from us, that is, they go out from the Church; but they would not go out, if they were of us. Therefore, before they went out they were not of us. If before they went out they were not of us, many are within, are not gone out, but yet are antichrists. We dare to say this: and why, but that each one while he is within may not be an antichrist? For he is about to describe and mark the antichrists, and we shall see them now. And each person ought to question his own conscience, whether he be an antichrist. For antichrist in our tongue means, contrary to Christ. Not, as some take it, that antichrist is to be so called because he is to come ante Christum, before Christ, i.e. Christ to come after him: it does not mean this, neither is it thus written, but Antichristus, i.e. contrary to Christ. Now who is contrary to Christ ye already perceive from the apostle's own exposition, and understand that none can go out but antichrists; whereas those who are not contrary to Christ, can in no wise go out. For he that is not contrary to Christ holds fast in His body, and is counted therewith as a member. The members are never contrary one to another. The entire body consists of all the members. — Ten Homilies on 1 John 3 Augustine of Hippo : "They went out from us; but," be not sad, "they were not of us." How provest thou this? If they had been of us, they would doubtless have continued with us. Hence therefore ye may see, that many who are not of us, receive with us the Sacraments, receive with us baptism, receive with us what the faithful know they receive, Benediction, the Eucharist, and whatever there is in Holy Sacraments: the communion of the very altar they receive with us, and are not of us. Temptation proves that they are not of us. When temptation comes to them as if blown by a wind they fly abroad; because they were not grain. But all of them will fly abroad, as we must often tell you, when once the fanning of the Lord's threshing-floor shall begin in the day of judgment. "They went out from us, but they were not of us; if they had been of us, they would no doubt have continued with us." For would ye know, beloved, how most certain this saying is, that they who haply have gone out and return, are not antichrists, are not contrary to Christ? Whoso are not antichrists, it cannot be that they should continue without. But of his own will is each either an antichrist or in Christ. Either we are among the members, or among the bad humors. He that changeth himself for the better, is in the body, a member: but he that continues in his badness, is a bad humor; and when he is gone out, then they who were oppressed will be relieved. — Ten Homilies on 1 John 3 Augustine of Hippo : For hear and see. Certainly all who go out from the Church, and are cut off from the unity of the Church, are antichrists; let no man doubt it: for the apostle himself hath marked them, "They went out from us, but they were not of us; for if they had been of us, they would no doubt have continued with us." Therefore, whoso continue not with us, but go out from us, it is manifest that they are antichrists. — Ten Homilies on 1 John 3 Augustine of Hippo : But let us not be made sad: "They went out from us, but they were not of us for if they had been of us, they would no doubt have continued with us." If then they went out from us, they are antichrists; if they are antichrists, they are liars; if they are liars, they deny that Jesus is the Christ. Once more we come back to the difficulty of the question. Ask them one by one; they confess that Jesus is the Christ. The difficulty that hampers us comes of our taking what is said in the Epistle in too narrow a sense. At any rate ye see the question; this question puts both us and them to a stand, if it be not understood. Either we are antichrists, or they are antichrists; they call us antichrists, and say that we went out from them; we say the like of them. But now this epistle has marked out the antichrists by this cognizance: "Whosoever denies that Jesus is the Christ," that same "is an antichrist." Now therefore let us enquire who denies; and let us mark not the tongue, but the deeds. — Ten Homilies on 1 John 3 Bede : "They went out from us, but they were not of us. It seemed to be mourned as a loss when we heard: 'They went out from us'; but soon consolation is added, when it is said: 'But they were not of us.' For it is evident that only Antichrists can go out from us, but those who are not opposed to Christ cannot in any way go out; for he who is not opposed to Christ, remains in His body. But there are those who are within the body of the Lord, while the body is still being healed, and perfect health will not be until the resurrection of the dead. They are in the body of Christ as evil humors; when they are vomited out, the body is relieved. So too the wicked, when they go out, the Church is relieved. 'They went out from us,' it says, but, 'do not be sad, they were not of us.' How do you prove it? — Commentary on the Catholic Epistles Bede : For if they had been of us, they would have continued with us. Therefore, it must be seen that many who are not of us receive the sacraments of Christ with us. But temptation proves that they are not of us, for when temptation comes to them, like the wind they fly away, because they were not the grain. However, they will all fly away when the Lord's threshing floor begins to be winnowed on the day of judgment. If some indeed go out by sinning but return through repentance, they are not Antichrists, but are proven to be in Christ, if the end of this present life finds them remaining in the Church. — Commentary on the Catholic Epistles Bede : But so that it may be evident, because not all who are within us are of us. Therefore, by the permission of the Lord, some go out from the Church even before the final winnowing, showing that they were not members of the Church, nor did they belong to the body of Christ, so that it may be clearly manifest that not all who are placed inside with us and receive the sacraments of Christ are of us, but only those who do works worthy of those same sacraments in the unity of the Church of Christ." — Commentary on the Catholic Epistles Clement of Alexandria ((as quoted by Cassiodorus)) : "They went out from us; but they were not of us"-neither the apostate angels, nor men falling away;-"but that they may be manifested that they are not of us." With sufficient clearness he distinguishes the class of the elect and that of the lost, and that which remaining in faith "has an unction from the Holy One," which comes through faith. He that abideth not in faith. — From the Latin Translation of Cassiodorus Cyprian : Has once learned, never departs from Him at all, and that those are the Church who remain in the house of God; but that, on the other hand, they are not the plantation planted by God the Father, whom we see not to be established with the stability of wheat, but blown about like chaff by the breath of the enemy scattering them, of whom John also in his epistle says, "They went out from us, but they were not of us; for if they had been of us, no doubt they would have continued with us.". — Epistle LIV Cyprian : What does the fierceness of wolves do in the Christian breast? What the savageness of dogs, and the deadly venom of serpents, and the sanguinary cruelty of wild beasts? We are to be congratulated when such as these are separated from the Church, lest they should lay waste the doves and sheep of Christ with their cruel and envenomed contagion. Bitterness cannot consist and be associated with sweetness, darkness with light, rain with clearness, battle with peace, barrenness with fertility, drought with springs, storm with tranquillity. Let none think that the good can depart from the Church. The wind does not carry away the wheat, nor does the hurricane uproot the tree that is based on a solid root. The light straws are tossed about by the tempest, the feeble trees are overthrown by the onset of the whirlwind. The Apostle John execrates and severely assails these, when he says, "They went forth from us, but they were not of us; for if they had been of us, surely they would have continued with us." — Treatise I. On the Unity of the Church Cyprian : That we must not speak with heretics. To Titus: "A man that is an heretic, after one rebuke avoid; knowing that one of such sort is perverted, and sinneth, and is by his own self condemned." Of this same thing in the Epistle of John: "They went out from among us, but they were not of us; for if they had been of us, they would doubtless have remained with us." Also in the second to Timothy: "Their word doth creep as a canker." — Treatise XII. Three Books of Testimonies Against the Jews. Oecumenius : "They went out from us, but they were not of us: for if they had been of us, they would have continued with us; but they went out, that it might be revealed that they were not all of us." "They went out from us." However, John adds this, having laid down or started nothing for the explanation of the speech: I say, as if John had asked himself: And where do these "antichrists" (1 Jn. 2:18) come from? Then he would have added, They went out from us. Since it ought to have been done this way, he does not do this, but rather in a confused manner, perhaps showing through the confusion of speech the distress John had concerning them. But why are those who went out from the Lord's disciples called antichrists? So that they could be regarded as trustworthy by those who were being led astray, as if they were from the disciples, and they made their preaching in accordance with the teacher's and instructor's opinion: nor did they have a completely contrary preaching. Therefore, it is said of them, "They went out from us." For when they became disciples, they departed from the truth and found their own blasphemy. It must be understood, however, from where these antichrists came, so that the statement may be clearer. "but they were not of us." That is, concerning the sort of those who are saved: for if they had been of us, they would have continued with us. But now it has happened to them that they became revealed, that is, it became known to all that they were completely alienated from us, and joined to those who were not of us. For there are among them some who were never of us, to whom they have joined themselves, who have went out from us. Because of these things, John said, "not all are of us." For among us, who were domestic and familiar, others followed those who were external to us: choosing rather to live self-indulgently in the manner of the pagans than moderately and honorably with us. — Commentary on 1 John Tertullian : Did not certain of the disciples turn back from the Lord Himself, when they were offended? Yet the rest did not therefore think that they must turn away from following Him, but because they knew that He was the Word of Life, and was come from God, they continued in His company to the very last, after He had gently inquired of them whether they also would go away. It is a comparatively small thing, that certain men, like Phygellus, and Hermogenes, and Philetus, and Hymenæus, deserted His apostle: the betrayer of Christ was himself one of the apostles. We are surprised at seeing His churches forsaken by some men, although the things which we suffer after the example of Christ Himself, show us to be Christians. "They went out from us," says (St. John, ) "but they were not of us. If they had been of us, they would no doubt have continued with us." — The Prescription Against Heretics
