Brainwashing, Thought Control and the Cults
PsychologicalandBiblicalOverview
Why do people start cults?
Few set out to "start a cult," at least intentionally. Rather, they are individuals who feel they have something to offer that no one else has; some special understanding or anointing from God, etc. Their opinion of themselves gets inflated, and they soon allow for no dissention or differences of opinion among their followers. Their growing number of recruits give them a sense of power and affirmation, further corrupting their fallen nature. Gradually they lose any real humility, fully believing they are God's sole spokesman to the world.
Why do these leaders reject orthodox Christianity?
Orthodoxy has been established over a period of 1900 years by Christian leaders and theologians who have battled heresy with sound logic from the Word of God. They recognize that theology is complex. Within orthodoxy, many of the finer points of belief can be debated over and over, leaving differences of opinion, while both sides retain the same basic beliefs. An upandcoming cult leader, however, considers himself superior to the church and its scholars, writing them off as uneducated fools; while nurturing the belief that he is God's spokesman to the world. Often ignoring the work of Greek and Hebrew scholars and seminarians, he sets himself up as the sole interpreter of the Bible.
