Do Mormons believe in the one God?

Mormonism, officially known as The Church of Jesus Christ of Latter-day Saints (LDS Church), presents a theological framework that diverges significantly from traditional biblical Christianity. One of the central questions is whether Mormons believe in one God. While their early writings, such as the Book of Mormon, claim belief in one God (1 Nephi 13:41), later doctrines and teachings developed by Joseph Smith and other church leaders clearly contradict the biblical concept of the Godhead. The Bible teaches that there is one God in three Persons: the Father, the Son, and the Holy Spirit (Isaiah 43:10; 44:6, 8; 45:5). In contrast, Mormon theology introduces the concept of multiple gods, the potential divinization of humans, and the anthropomorphization of God. These teachings represent a radical departure from Scripture.

Mormons’ Rejection of the One God

Although the Book of Mormon initially affirms monotheism, later Mormon doctrine contradicts this. The Book of Abraham, a text unique to Mormon scripture, introduces the idea of many gods (Abraham 4:3). This is a foundational departure from biblical monotheism. Furthermore, prominent Mormon writers, such as James Talmage, confirm the LDS Church’s denial of the biblical Godhead (Articles of Faith, p. 35).

Joseph Smith, the founder of Mormonism, explicitly rejected the doctrine of the Trinity, which is central to biblical Christianity. He wrote, “Many men say there is one God; the Father, the Son and the Holy Ghost are only one God. I say that is a strange God. All are crammed into one God according to sectarianism [the Christian faith]. It would make the biggest God in all the world. He would be a wonderfully big God-he would be a giant or a monster” (Teachings of the Prophet Joseph Smith, p. 372). Smith’s rejection of the Trinity shows that Mormonism does not align with the biblical understanding of one God existing eternally in three Persons.

The Doctrine of Many Gods

In Mormonism, the Godhead consists of three separate gods: the Father, the Son, and the Holy Ghost (Articles of Faith, by Talmage, pp. 35-40). This is fundamentally different from the biblical teaching that there is only one God (Isaiah 43:10; 44:6, 8; 45:5). The Bible presents the Father, Son, and Holy Spirit as distinct Persons yet unified in essence, co-eternal, and co-equal (John 1:1-2, 14; 2 Corinthians 13:14). In contrast, Mormon theology treats these three as separate gods working in unity, but each possessing individual divine status.

This departure from biblical monotheism has significant theological implications. By teaching that there are multiple gods, Mormonism undermines the unique authority, sovereignty, and eternal nature of God. The God of the Bible alone is self-existent and eternal (Revelation 1:8; 1 Timothy 1:17; Psalm 102:24-27). By contrast, Mormon theology introduces the possibility that gods themselves were once humans or spirits who attained godhood, thereby denying the biblical understanding of God as eternal and uncreated.

Man Can Become a God

A distinctive and controversial teaching in Mormonism is the belief that humans can become gods. Joseph Smith taught that God Himself was once a man who progressed to divinity (Mormon Doctrine, p. 321; Teachings of the Prophet Joseph Smith, p. 345). This directly contradicts the Bible, which declares that God is eternal, self-existent, and unchanging (Numbers 23:19; 1 Samuel 15:29; Hosea 11:9).

Mormon theology also asserts that faithful humans can achieve godhood through obedience and good works, a concept known as exaltation (Teachings of the Prophet Joseph Smith, pp. 345-354). In this view, humans can eventually populate other worlds as gods themselves (Doctrine & Covenants 132:20). This teaching is a radical departure from biblical truth, which clearly affirms that no human can ever become God (1 Samuel 2:2; Isaiah 43:10-11; 44:6; 45:21-22). Such a belief originates in the deception introduced by Satan in the Garden of Eden (Genesis 3:5), where he suggested that humans could “be as gods.”

The implication of this doctrine is that the number of gods is potentially infinite, as every human can attain divinity and create new worlds. This stands in stark contrast to the biblical assertion of God’s uniqueness, sovereignty, and eternal existence.

Jesus and Lucifer as Brothers

Mormonism further diverges from biblical teaching by asserting that Jesus Christ and Lucifer are both spirit children of God the Father. In Mormon doctrine, Jesus is considered “a son of God” (Alma 36:17) and Lucifer, or Satan, is another son of God (Mormon Doctrine, p. 163). Furthermore, Jesus is described as a created being, the first spirit born of God and a celestial mother (Mormon Doctrine, pp. 129, 516).

The Bible, however, consistently presents Jesus as eternal, the uncreated Son of God (John 1:1-3; Colossians 1:15-17). The idea that Jesus and Lucifer are literal brothers contradicts Scripture, which distinguishes Christ as the eternal Son who shares fully in the divine nature with the Father (Hebrews 1:3-4). Satan, in contrast, is a created angelic being who rebelled against God (Isaiah 14:12-14; Ezekiel 28:12-17).

This teaching also undermines the uniqueness of Christ’s divinity and His role as Savior. In Mormonism, Jesus is elevated to Godhood only through progression, whereas the Bible affirms that Christ was God from eternity and required no progression to divinity (John 1:1; Philippians 2:6-7).

God Is Flesh and Bones

A further divergence is the Mormon belief that God the Father and Jesus Christ have bodies of flesh and bones. Joseph Smith declared, “The Father has a body of flesh and bones as tangible as man’s” (Doctrine and Covenants 130:22; Articles of Faith, p. 38). This anthropomorphized view of God is inconsistent with biblical teaching, which presents God as Spirit (John 4:24), eternal (John 1:1-2), and the Creator of all things (John 1:3; Colossians 1:16-17).

The Bible teaches that God is invisible (1 Timothy 1:17), omnipresent (Psalm 139:7-10), and not confined to physical form (Acts 17:24-25). To claim that God has a tangible human body limits His omnipotence, omniscience, and transcendence, attributes that are central to biblical understanding.

Other Contradictions with Biblical Christianity

Beyond the nature of God, Mormonism contradicts other core biblical doctrines. The reliance on additional scriptures such as the Book of Mormon, Doctrine and Covenants, and Pearl of Great Price as sources of divine authority undermines the sufficiency of the Bible (2 Timothy 3:16-17; Revelation 22:18-19). Salvation, according to Mormonism, involves works and obedience, including temple rituals, rather than faith alone in Jesus Christ (Ephesians 2:8-9; Romans 10:9-10).

Furthermore, the LDS view of sin, grace, and the atonement differs significantly from Scripture. In biblical Christianity, salvation is a free gift of God’s grace, and Jesus’ death provides complete atonement for sin (Hebrews 10:10; 1 John 2:2). In Mormonism, the atonement is supplemented by human effort, which diminishes the sufficiency of Christ’s sacrifice.

Conclusion

Mormonism does not teach the biblical doctrine of one God. Although early texts such as the Book of Mormon may claim monotheism, the development of later doctrines-particularly the belief in multiple gods, the potential divinization of humans, Jesus and Lucifer as brothers, and God as a physical being-represents a profound deviation from Scripture. The Bible consistently affirms the existence of one eternal, uncreated God in three Persons: the Father, the Son, and the Holy Spirit (Isaiah 43:10; 44:6; John 1:1-3; 2 Corinthians 13:14).

Mormonism’s rejection of the Trinity, its anthropomorphization of God, and its teaching that humans can become gods place it outside the bounds of historic biblical Christianity. While Mormons may self-identify as Christians, their theology contradicts the clear teachings of Scripture concerning the Godhead, the nature of Christ, salvation, and the uniqueness of God.

For those seeking biblical truth, it is essential to rely on the Bible as the final authority, recognizing God’s eternal, unchangeable nature, Christ’s eternal divinity, and the unity of the Godhead in three Persons. The distinctions between Mormon beliefs and biblical Christianity demonstrate the importance of understanding and adhering to the Word of God alone.
