'Anti christ' in the Bible

Who is the real liar? who but he who denies that Jesus is the Christ? This is 'antichrist,' he who disowns the Father and the Son.

and every spirit which does not confess Jesus [incarnate] does not come from God. This latter is the spirit of antichrist; you were told it was coming, and here it is already in the world.

I say this, because a number of impostors have emerged in the world, men who will not acknowledge the coming of Jesus Christ in the flesh; that marks the real 'impostor' and 'antichrist.'
