From Christian Reformed Ink Archives:
The reason Mormonism is not Christian is because it denies one or more of the essential doctrines of Christianity. Of the essential doctrines (that there is only one God, Jesus is God in flesh, forgiveness of sins is by grace alone, and Jesus rose from the dead physically, the gospel being the death, burial, and resurrection of Jesus), Mormonism denies three of them: how many gods there are, the person of Jesus, and His work of salvation.
