““Almost every book in the NT has something to say about false beliefs and those who advocate them. We are warned, e.g., about false prophets (Matt. 7:15–16; 24:11), false christs (Matt. 24:5, 24; Mark 13:22), a different Jesus and a different spirit (2 Cor. 11:4), false apostles (2 Cor. 11:13–15), and “another gospel” (Gal. 1:8). With so many warnings, it is clear God knew that many false teachers would come, and that he did not want his people to be deceived (cf. Eph. 4:14; 2 John 7). In what follows, notable deceptions of prominent cults will be summarized, along with a brief biblical response. From the viewpoint of those who hold to historic, evangelical Christianity, a “cult” is any religious movement that claims to be derived from the Bible and/or the Christian faith, and that advocates beliefs that differ so significantly with major Christian doctrines that two consequences follow: (1) The movement cannot legitimately be considered a valid “Christian” denomination because of its serious deviation from historic Christian orthodoxy. (2) Believing the doctrines of the movement is incompatible with trusting in the Jesus Christ of the Bible for the salvation that comes by God’s grace alone (Eph. 2:8–9). By this traditional understanding of the word “cult,” the following groups described are “cults,” though this does not imply that they share the extremely oppressive, authoritarian, life-controlling, and often immoral practices that are found in what the secular world calls “cults,” using the term in a more extreme sense.””
