Changes

It has been widely known that Mormonism has a history where polygamy has been accepted, although today most mainstream Mormon denominations do not advocate polygamy. Joseph Smith himself had multiple wives, anywhere between 28 and 49 wives: many of whom were concurrently married when Smith married them. Most of his wives were married to him within the last 3 years of Smith's life.

Mormons generally believe in the existence of multiple gods(some denominations believe in one). This is rooted in the denial that the Father, the Son, and the Holy Spirit share the same being and substance. This stems from the normal Mormon assumption that a person necessarily has his own, unshared being. The baptism of Jesus, for example, is seen as an interaction between three god-beings, not just three persons<ref>Smith, The Teachings of the Prophet Joseph Smith, 346-7; Abraham 4:1, Pearl of Great Price; and Gospel Principles, 290</ref>.
