No, anyone that denies Christ is an anti-Christ. They existed in the first century time as well as today.
1 John 2:18 Children, it is the last hour, and as you have heard that antichrist is coming, so now many antichrists have come. Therefore we know that it is the last hour.
1 John 2:22 Who is the liar but he who denies that Jesus is the Christ? This is the antichrist, he who denies the Father and the Son.
Anyone that denies Jesus is the Christ is the antichrist.
1 John 4:3 and every spirit that does not confess Jesus is not from God. This is the spirit of the antichrist, which you heard was coming and now is in the world already.
The antichrist is in the world already in the first century. See above.
2 John 1:7 For many deceivers have gone out into the world, those who do not confess the coming of Jesus Christ in the flesh. Such a one is the deceiver and the antichrist.
They have already gone out into the world. It is not a prophecy of something to occur thousands of years later.
Y!A is full of antichrist.
