Antichrist: against Christ, or an opposition Christ, a rival Christ. The word is used only by the apostle John. Referring to false teachers, he says (1 John 2:18,22; 4:3; 2 John 1:7), "Even now are there many antichrists."
This name has been applied to the "little horn" of the "king of fierce countenance" (Daniel 7:24,25; 8:23-25).
It has been applied also to the "false Christs" spoken of by our Lord (Matthew 24:5,23,24).
