Antichrist - ἀντίχριστος simply translated means one who is against Christ. The hype surrounding the idea of "Antichrist" that has reached such popularity among evangelicals is manufactured out of a mishandling of a number of texts. This nomenclature has been assigned to texts where it simply does not belong.
These passages represent EVERYTHING scripture tells us about an antichrist.
1 John 2:18-22 - "Children, it is the last hour; and just as you heard that antichrist is coming, even now many antichrists have appeared; from this we know that it is the last hour. They went out from us, but they were not really of us; for if they had been of us, they would have remained with us; but they went out, so that it would be shown that they all are not of us. But you have an anointing from the Holy One, and you all know. I have not written to you because you do not know the truth, but because you do know it, and because no lie is of the truth. Who is the liar but the one who denies that Jesus is the Christ? This is the antichrist, the one who denies the Father and the Son."
1 John 4:1-3 - "Beloved, do not believe every spirit, but test the spirits to see whether they are from God, because many false prophets have gone out into the world. By this you know the Spirit of God: every spirit that confesses that Jesus Christ has come in the flesh is from God; and every spirit that does not confess Jesus is not from God; this is the spirit of the antichrist, of which you have heard that it is coming, and now it is already in the world."
2 JOHN 7 - "For many deceivers have gone out into the world, those who do not acknowledge Jesus Christ as coming in the flesh. This is the deceiver and the antichrist."
In 1 John. 2:8-22 and 4:1-3
1. His presence marked the last hour at the time John wrote this epistle.
2. Antichrist was not a singular individual but a collective.
3. They came out of the Body.
4. They denied the Father and the Son.
5. They were false prophets.
6. They were already in the world when John wrote this epistle.
7. They were of the world.
8. They possessed the spirit of error.
2 John.
1. Again, John defines them as a collectivity of deceivers.
2. They had gone out into the world.
3. They denied that Jesus came in the flesh.
This is everything the Bible says about an antichrist. Everything else is speculation, conjecture, and misrepresentation of selected scriptures.
The word antichrist never appears anywhere in the book of Revelation. The insistance of many that an individual called the antichrist is in any way referred to in Revelation is completely without justification.
