AN'TI-CHRIST, n. [Gr. αντι, against, and Christ.]

A great adversary of Christ; the man of sin; described 1 John ii. 18. 2 Thess. ii. Rev. ix. Protestants generally suppose this adversary to be the Papal power; and some divines believe that, in a more general sense, the word extends to any persons who deny Christ or oppose the fundamental doctrines of Christianity. – Encyc. Brown. Buck.
