Although Mormonism believes that the Godhead consists of three gods, they also believe in the existence of multiple gods outside of these three. This is rooted in the denial that the Father, the Son, and the Holy Spirit share the same being and/or substance. The baptism of Jesus, for example, is seen as an interaction between three god-beings, not just three persons. Additionally, the first Mormon Prophet, Joseph Smith, taught that God the Father was once a man like us, living on another planet with a God ruling over it. Our God later became a God and fathered our spirits. The Mormon scriptures (The Pearl of Great Price, Book of Moses) as well as the Mormon Temple endowment ceremony explicitly teach of multiple Gods. (cf. Smith, The Teachings of the Prophet Joseph Smith, 341-7; Abraham 4:1, Pearl of Great Price; and Gospel Principles, 290).
