The Bible Dictionary states that an anti-Christ 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” (“Antichrist,” 609).
Elder Bruce R. McConkie (1915–85) of the Quorum of the Twelve Apostles further taught: “An antichrist is an opponent of Christ; he is one who is in opposition to the true gospel, the true Church, and the true plan of salvation. (1 John 2:19; 4:4–6.) He is one who offers salvation to men on some other terms than those laid down by Christ. Sherem (Jac. 7:1–23), Nehor (Alma 1:2–16), and Korihor (Alma 30:6–60) were antichrists who spread their delusions among the Nephites” (Mormon Doctrine, 2nd ed. [1966], 39–40).
