Based on this definition, the Seventh Day Adventist Church could be considered a cult. While they call themselves Christian (and probably many who attend Adventist churches are, in fact, believers in Jesus Christ), the organization itself professes unbiblical and harmful doctrines and beliefs outside the mainstream of orthodox Christianity.
Their movement originated in 1836 with William Miller (1782-1849), a false prophet who claimed to know that the second coming of Christ would happen in 1843. When this prediction proved false, many left the movement in a period called “The Great Disappointment.” Given this man’s obvious fraud, we might assume his followers would abandon him quickly since he failed the basic biblical test for the office of prophet.
