Do Latter-day Saints believe in more than one God?

The short answer

Latter-day Saints worship the Father through Jesus Christ and believe the Father, Son, and Holy Ghost are three distinct beings united as one Godhead. Exaltation means receiving divine glory through Christ. The Father remains our God. Isaiah affirms the Lord’s unique power to save, while the Latter-day Saint teaching on exaltation also draws on modern revelation.

The claim in its strongest form

Latter-day Saints believe in three separate divine beings, Father, Son, and Holy Ghost, each with distinct bodies or personages. They also teach that God the Father was once a man who progressed to godhood (the King Follett discourse), that God has a heavenly father, and that faithful humans can become gods of their own worlds. This is polytheism by any reasonable definition: multiple gods who were once humans, an infinite regress of deities, and the promise of future deification for believers. The Bible unequivocally declares 'I am the Lord, and there is no other' (Isaiah 45:5). No amount of redefining 'monotheism' changes the fact that belief in multiple gods with the promise of becoming one yourself is polytheism.

The answer in a conversation

Latter-day Saints worship the Father through Jesus Christ and teach that the Father, Son, and Holy Ghost are distinct beings united in purpose and doctrine. This differs from the Nicene account of three distinct persons sharing one divine substance. Latter-day Saints also believe that God can give his children a share in his glory through Christ. They continue to worship him. Godhead · Becoming Like God

Read the verse before deciding what it rules out

Jeff Durbin and Bill McKeever argue that Isaiah 43:10 rules out mortals becoming gods. Take the claim seriously and read through verse 13. The Lord calls Israel as his witness and declares that he alone saves. Isaiah 44 repeats his exclusivity and mocks idols that cannot deliver anyone. Does that also rule out God sharing his glory with his children? That is the point to test. Isaiah 43:9–13 · Isaiah 44:6–20 · Durbin’s transcript · McKeever’s article

Compare what believers receive

  • Paul calls believers joint heirs with Christ and says they can be glorified with him. Romans 8:14–17
  • Peter speaks of partaking of the divine nature. 2 Peter 1:3–4
  • Doctrine and Covenants 76 calls the exalted gods and describes them receiving from the Father, belonging to Christ, and dwelling with God forever. Doctrine and Covenants 76:55–62

The New Testament gives Christians a basis for talking about sharing in divine life. The fuller Latter-day Saint account also depends on modern revelation.

I agree with Isaiah that the Lord alone can save. What I believe about exaltation is that through Christ, God gives his children a share in his glory. What in Isaiah rules out receiving that gift from him?
