Many religious groups exercise unbiblical control over their people.
They are authoritarian cults. Often there is a single leader around whose personality the religious group revolves. One way that such power and control is justified is by stating or implying that the leader has assumed the mantle of Moses. They teach that the leader is called to exercise similar authority among the people as Moses' authority among Israel. The Mormons teach that Moses came to earth to take part in giving the keys of the Kingdom to Joseph Smith in 1836.
