For - Ὅτι Hoti. This word "for" is not here to be regarded as connected with the previous verse, and as giving a reason why there should be the exercise of mutual love, but is rather to be understood as connected with the following verse, 2 John 1:8, and as giving a reason for the caution there expressed: "Because it is a truth that many deceivers have appeared, or since it has occurred that many such are abroad, look to yourselves lest you be betrayed and ruined." The fact that there were many such deceivers was a good reason for being constantly on their guard, lest they should be so far drawn away as not to receive a full reward.

Many deceivers are entered into the world - Are abroad in the world, or have appeared among men. Several manuscripts read here, "have gone out into the world," (ἐξῆλθον exēlthon,) instead of "have entered into," εἰσῆλθον eisēlthon. The common reading is the correct one, and the other was originated, probably, from the unusual form of the expression, "have come into the world," as if they had come from another abode. That, however, is not necessarily implied, the language being such as would he properly used to denote the idea that there were such deceivers in the world.

Who confess not that Jesus Christ is come in the flesh - Who maintain that he assumed only the appearance of a man, and was not really incarnate. See the notes at 1 John 4:2-3.

This is a deceiver - Everyone who maintains this is to be regarded as a deceiver.

And an antichrist - See the notes at 1 John 2:18; 1 John 4:3.

For many deceivers, etc. - Of these he had spoken before, see 1 John 4:1, etc. And these appear to have been Gnostics, for they denied that Jesus was come in the flesh. And this doctrine, so essential to salvation, none could deny but a deceiver and an antichrist. Instead of εισηλθον are entered in, many excellent MSS. and versions have εξηλθον, are gone out. The sense is nearly the same.

For many deceivers are entered into the world,.... By whom are meant false teachers, who are described by their quality, "deceivers", deceitful workers, pretending to be ministers of Christ, to have a: value for truth, a love for souls, and a view to the glory of God, but lie in wait to deceive, and handle the word of God deceitfully; and by their quantity or number, "many", and so likely to do much mischief; and by the place where they were, they were "entered into the world"; or "gone out into the world", as the Alexandrian copy and some others, and the Vulgate Latin and Syriac versions read; See Gill on 1 John 4:1; and by their tenet,

who confess not that Jesus Christ is come in the flesh; these were not the Jews who denied that Jesus was the Christ, though they would not allow that Christ was come in the flesh; but these were some who bore the Christian name, and professed to believe in Jesus Christ, but would not own that he was really incarnate, or assumed a true human nature, only in appearance; and denied that he took true and real flesh of the virgin, but only seemed to do so; and these are confuted by the apostle, 1 John 1:1; and upon everyone of these he justly fixes the following character.

This is a deceiver and an antichrist; one of the deceivers that were come into the world, and one of the antichrists that were already in it; and who were the forerunners of the man of sin, and in whom the mystery of iniquity already began to work; for antichrist does not design anyone particular individual person, but a set of men, that are contrary to Christ, and opposers of him.

Deceivers (πλάνοι)

See on we deceive ourselves, 1 John 1:8.

Are entered into (ἐξῆλθαν εἰς)

Rev., are gone forth into. The A.V. follows the reading εἰσῆλθον entered into. The tense is the aorist, strictly rendered, went forth. It may indicate a particular crisis, at which they went forth from the Christian society.

Who confess not (οἱ μὴ ὁμολογοῦντες)

The article with the participle describes the character of this class of deceivers, and does not merely assert a definite fact concerning them. Compare Mark 15:41, "other women which came up with Him" (αἱ συνσνσβᾶσαι). Confess. See on Matthew 7:23; see on Matthew 10:32.

Is come (ἐρχόμενον)

Wrong. The verb is in the present participle, coming, which describes the manhood of Christ as still being manifested. See on 1 John 3:5. In 1 John 4:2 we have the manifestation treated as a past fact by the perfect tense, ἐληλυθο.τα has come. Rev., that Jesus Christ cometh. So in 1 Thessalonians 1:10, τῆς ὀργῆς τῆς ἐρχομένης is the wrath which is coming; which has already begun its movement and is advancing: not merely, as A.V., the wrath to come, which makes it wholly a future event. See on lingereth, 2 Peter 2:3.

An antichrist (ὁ ἀντίχριστος)

Rev, rendering the definite article, the antichrist. See on 1 John 2:18.

{3} For many deceivers are entered into the world, who confess not that Jesus Christ is come in the flesh. This is a deceiver and an antichrist.

(3) Antichrists fighting against the person and office of Christ had already crept into the Church, in the time of the apostles.

1:7 For many deceivers are entered into the world. See notes on 1Jo 2:18 2:22-24 4:1.

An antichrist. Opposed to Christ.

1:7 Carefully keep what ye have heard from the beginning, for many seducers are entered into the world, who confess not Jesus Christ that came in the flesh - Who disbelieve either his prophetic, or priestly, or kingly office. Whosoever does this is the seducer - From God. And the antichrist - Fighting against Christ.

Margin world

kosmos = mankind. See Scofield Note: "Mt 4:8".

7. As love and truth go hand in hand (2Jo 3, 4), he feels it needful to give warning against teachers of untruth.

For-giving the reason why he dwelt on truth and on love, which manifests itself in keeping God's commandments (2Jo 6).

many-(1Jo 2:18; 4:1).

are entered-The oldest manuscripts read, "have gone forth," namely, from us.

confess not . Jesus . in the flesh-the token of Antichrist.

is come-Greek, "coming." He who denies Christ's coming in the flesh, denies the possibility of the incarnation; he who denies that he has come, denies its actuality. They denied the possibility of a Messiah's appearing, or coming, in the flesh [Neander]. I think the Greek present participle implies both the first and the second advent of Christ. He is often elsewhere called the Coming One (Greek), Mt 11:3; Heb 10:37. The denial of the reality of His manifestation in the flesh, at His first coming, and of His personal advent again, constitutes Antichrist. "The world turns away from God and Christ, busily intent upon its own husks; but to OPPOSE God and Christ is of the leaven of Satan" [Bengel].

This is a, &c.-Greek, "This (such a one as has been just described) is the deceiver and the Antichrist." The many who in a degree fulfil the character, are forerunners of the final personal Antichrist, who shall concentrate in himself all the features of previous Antichristian systems.

1:7-11 The deceiver and his deceit are described: he brings some error concerning the person or office of the Lord Jesus. Such a one is a deceiver and an antichrist; he deludes souls, and undermines the glory and kingdom of the Lord Christ. Let us not think it strange, that there are deceivers and opposers of the Lord Christ's name and dignity now, for there were such, even in the apostles' times. The more deceivers and deceits abound, the more watchful the disciples must be. Sad it is, that splendid attainments in the school of Christ, should ever be lost. The way to gain the full reward is, to abide true to Christ, and constant in religion to the end. Firm cleaving to Christian truth unites us to Christ, and thereby to the Father also; for they are one. Let us equally disregard such as abide not in the doctrine of Christ, and those who transgress his commands. Any who did not profess and preach the doctrine of Christ, respecting him as the Son of God, and salvation by him from guilt and sin, were not to be noticed and countenanced. Yet in obeying this command, we must show kindness and a good spirit to those who differ from us in lesser matters, but hold firmly the all-important doctrines of Christ's person, atonement, and holy salvation.
