Anyone or anything that counterfeits the true gospel plan of salvation and that openly or secretly opposes Christ. John the Revelator described the antichrist as a deceiver (1 Jn. 2: 18-22; 4: 3-6; 2 Jn. 1: 7). The great antichrist is Lucifer, but he has many assistants, both spirit beings and mortals.

The son of perdition opposes and exalts himself above all that is called God, 2 Thes. 2: 1-12. He deceives them that dwell on the earth by the means of miracles, Rev. 13: 13-17. Sherem denied Christ and deceived many, Jacob 7: 1-23. Nehor taught false doctrines, established a church, and introduced priestcraft, Alma 1: 2-16. Korihor ridiculed Christ, the Atonement, and the spirit of prophecy, Alma 30: 6-60.
