I was raised Mormon and it took me a long time to understand how fundamentally different it is from historic Christianity. Even as recently as 3 years ago, I didn't get why it was a big deal that we didn't believe in the Trinity
Mormon theology does not present God as an "uncaused cause", existence itself, the "Logos". In Mormonism, God *is* a "man in the sky", a created being, someone who was once human but is now exalted within our known universe. This opens up a lot of problems imo. For example: what happens when death and evil are overcome on our planet, and you reach exaltation? You are now a God of a new universe/planet to create a new race of humanity and evil arises all over again and the drama continues into eternity? There is no message of the ultimate overcoming of death/evil as in historic Christianity
In all my childhood and young adult instruction in the LDS church, I never learned that Jesus was "God in the flesh" or anything like that. Jesus really was taught as a distinct BEING from God the Father (who again... Is a *created being*). It is a fundamentally different Christ that is believed and worshipped.
Bc Mormons view Christ as a spiritual brother of Satan. They believe He achieved progressive exaltation, distinct from and subordinate to the Father.
It is not a Trinitarian religion.
Mormonism teaches that Jesus was conceived by a Heavenly Father AND a Heavenly Mother (the Father’s divine wife).
It teaches that we can become gods like Christ and rule worlds.
Mormons are some of the nicest people around, but they are outside of biblical Christian teaching.
