Two Paths, One Pattern: Exploring the Surprising Similarities Between Islam and Mormonism

In a recent interfaith dialogue, I was struck by a fascinating observation: the remarkable similarities between Islam and Mormonism. At first glance, these two faiths might seem worlds apart, with distinct cultural and historical contexts. However, a closer examination reveals parallels that can shed light on their origins and theological structures. As a follower of Christ and someone deeply invested in studying comparative theology, I find these connections both intriguing and significant for interfaith discussions.

Founders with a Vision

Both Islam and Mormonism were founded by individuals who claimed direct revelation from God, leading to the establishment of new religious movements. Muhammad, in 7th-century Arabia, and Joseph Smith, in 19th-century America, asserted that they were chosen as prophets to restore the faith after it had been corrupted over time. Each received a central text—Muhammad, the Qur'an, and Joseph Smith, the Book of Mormon—purportedly through divine means. These texts are considered by their followers to supersede previous scriptures, reshaping the understanding of God, prophecy, and community.

A New Revelation

Central to both faiths is the belief that earlier revelations (the Bible, in particular) were either incomplete or corrupted. This claim justified the introduction of a new scripture that clarified and corrected previous misunderstandings. For Muslims, the Qur'an represents the final and most perfect revelation. For Mormons, the Book of Mormon serves as an additional testament of Jesus Christ, complementing but also correcting interpretations of the Bible.

This idea of a "restored truth" challenges the central Christian belief that the Bible, as God’s Word, is complete and sufficient. While Christians see the Bible as unified and authoritative, both Islam and Mormonism question its reliability, paving the way for their respective texts to claim theological primacy.

Community and Authority

Another striking similarity is the emphasis on community and hierarchical authority. Islam and Mormonism both foster strong, tightly-knit communities bound by shared practices, a distinct identity, and clear leadership structures. The caliphate in early Islam and the leadership of the Church of Jesus Christ of Latter-day Saints serve as examples of centralized authority, guiding adherents in spiritual and worldly matters.

Both movements also placed a high value on communal growth through missionary efforts. Islam rapidly expanded through the Arabian Peninsula and beyond, while Mormonism established its presence in America and globally through an organized missionary program.

Marriage Practices and Polygamy

Another noteworthy similarity between Islam and Mormonism is their historical allowance of polygamy. In Islam, polygamy is permitted under specific guidelines, with men allowed to marry up to four wives, provided they can treat them equally (Qur'an 4:3). Early Mormonism similarly embraced polygamy, with founder Joseph Smith and later leaders like Brigham Young teaching it as a divine principle. Although mainstream Mormonism officially discontinued the practice in 1890, some fundamentalist groups still adhere to it. These marriage practices highlight how both faiths have approached family structure and societal norms differently than the monogamous model emphasized in Christian teaching (Genesis 2:24, Matthew 19:4-6).

Prophetic Authority and Additional Texts

Both Muhammad and Joseph Smith hold singular authority within their faiths. Their teachings and lives serve as models for their followers, and their writings shape theology and practice. In Islam, the Hadith (sayings and actions of Muhammad) supplements the Qur'an, much like the Doctrine and Covenants and Pearl of Great Price supplement the Book of Mormon in Mormonism. These additional texts provide guidance on issues of law, worship, and governance, often reinforcing the founder’s role as God’s chosen messenger.

Works and Grace

The emphasis on works as a means of attaining divine favor is another area of commonality. In Islam, salvation is closely tied to a balance of deeds—prayer, fasting, and almsgiving are central acts of worship. Mormonism similarly emphasizes adherence to commandments, temple practices, and missionary work as integral to salvation.

This stands in contrast to the central Christian teaching that salvation comes through grace by faith in Jesus Christ, not by works, so that no one may boast (Ephesians 2:8-9). While good works flow naturally from a transformed life in Christ, they are not the basis for salvation—a fundamental difference from the frameworks of Islam and Mormonism.

A Call Back to Christ

Both Islam and Mormonism diverged from historical Christianity, presenting themselves as the fulfillment of corrupted or incomplete traditions. However, these paths lead away from the central truth of the Gospel: Jesus Christ is the eternal Word made flesh, the perfect and final revelation of God. He alone provides salvation, not through human effort or additional revelations, but through His sacrifice on the cross.

While these similarities highlight common human desires for restoration, structure, and divine connection, they also remind us of the unique and unchanging truth of the Gospel. As followers of Christ, we can engage with Muslims and Mormons with love, understanding, and clarity, pointing always to the sufficiency of Jesus as the Way, the Truth, and the Life.

Final Thoughts

Islam and Mormonism, though separated by time, geography, and culture, share striking parallels in their origin stories, theology, and practice. These similarities provide a bridge for meaningful dialogue, but they also highlight the importance of discerning truth. As we engage in conversations across faiths, may we do so with gentleness and respect, bearing witness to the hope and freedom found in Christ alone.

What are your thoughts on these parallels? How can we use these observations to deepen our conversations with friends of different faiths? I'd love to hear your reflections!
