A word used by John to describe one who would assume the guise of Christ but in reality would be opposed to Christ (1 Jn. 2:18–22; 4:3–6; 2 Jn. 1:7). In a broader sense it is anyone or anything that counterfeits the true gospel or plan of salvation and that openly or secretly is set up in opposition to Christ. The great antichrist is Lucifer, but he has many assistants both as spirit beings and as mortals. See 2 Thes. 2:1–12; Rev. 13:17; Jacob 7:1–23; Alma 1:2–16; 30:6–60.
