 For some who define Christianity within the doctrines of Catholicism, Eastern Orthodoxy, and Protestantism, Mormonism's differences place it outside the umbrella of Christianity.Since its beginnings, the faith has proclaimed itself to be Christ's Church restored with its original authority, structure and power; maintaining that existing denominations believed in incorrect doctrines and were not acknowledged by God as his church and kingdom.Though the religion quickly gained a large following of Christian seekers, in the 1830s, many American Christians came to view the church's early doctrines and practices as politically and culturally subversive, as well as doctrinally heretical, abominable, and condemnable.
