Does Mormonism REALLY teach that Jesus is the spirit brother of Satan? - Christian Research Institute
In sharp contrast to Mormon Christology, the biblical witness is clear and convincing: Jesus Christ is the eternal Creator God (John 1; Colossians 1; Hebrews 1; Revelation 1). Paul explicitly teaches that Jesus is the creator of all, including the angelic realm to which Satan belongs (Colossians 1:15–16; cf. John 1:3). Jesus is thus Satan’s creator, not his spirit brother.
