That Jesus is the Son of God is part and parcel of every Mormon’s testimony. They do not believe, however, that Jesus is equal with God the Father. “Jesus is greater than the Holy Spirit, which is subject unto him, but his Father is greater than he” (Book of Mormon Student Manual, p. 74). Jesus was Heavenly Father’s and Mother’s first spirit child and in this sense, he is the Son of God.
