I Believe Mormonism Is False
Every worldview must answer the most important questions of life. Who is God? Who is Jesus Christ? How can sinners be made right with God? What is the final authority for truth? Christianity and Mormonism—officially known as the Church of Jesus Christ of Latter-day Saints—offer radically different answers to these questions. While Mormonism uses much of the same religious vocabulary as Christianity, it gives many of those words entirely different meanings. After carefully comparing its teachings with the Bible, I believe Mormonism is false and that the biblical gospel alone is the power of God for salvation.
This conviction is not directed against Mormon people. Christians are commanded to love their neighbors, treat every person with dignity, and speak the truth with gentleness and respect. Many Latter-day Saints are devoted to their families, committed to moral living, and sincere in their religious beliefs. Their kindness and sincerity should be recognized and appreciated. Yet sincerity does not establish truth. A person can sincerely believe something that is false. The question is not whether someone is earnest, but whether what he believes is true according to God's revelation.
The ultimate authority for Christianity is the Bible alone. Christians believe that Scripture is God's inspired, inerrant, and sufficient Word. It is the final authority by which every doctrine, tradition, and spiritual experience must be tested. Mormonism, however, accepts additional writings, including the Book of Mormon, Doctrine and Covenants, and Pearl of Great Price, along with the continuing authority of modern prophets. This immediately creates two different foundations for truth. The Christian faith rests upon the completed revelation God has given in Scripture, while Mormonism claims further revelation that alters and expands upon biblical doctrine. The Apostle Paul warned the churches that even if an angel from heaven preached a different gospel, that message was to be rejected. God's revealed truth is not open to revision.
The greatest difference concerns the identity of God Himself. The Bible teaches that there is one eternal God who has always existed as Father, Son, and Holy Spirit. He is uncreated, infinite, and unchanging. There has never been another God before Him, nor will there ever be. Through the prophet Isaiah, the Lord declares, "Before me no god was formed, nor shall there be any after me." Mormonism, however, teaches that God the Father was once a man who progressed to godhood and that human beings may likewise become gods. These teachings are fundamentally incompatible with the Bible's clear declaration that God alone is eternally God.
The person of Jesus Christ is another decisive difference. Historic Christianity confesses that Jesus is the eternal Son of God, fully God and fully man. He was never created but has existed eternally with the Father and the Holy Spirit. Through Him all things were made. Mormonism speaks highly of Jesus but teaches a different Christ. Its theology has historically described Him as a spirit child of the Father and the firstborn among humanity in a way that differs fundamentally from the eternal Son revealed in Scripture. A different view of Christ inevitably leads to a different gospel.
The doctrine of salvation also separates Christianity from Mormonism. The Bible teaches that every person is guilty before a holy God and incapable of earning salvation through good works. We are justified by grace alone through faith alone because of Christ alone. Christ's perfect obedience is credited to believers, and His sacrificial death fully satisfies God's justice. Salvation is God's gift from beginning to end. As Paul writes in Ephesians, "By grace you have been saved through faith... not a result of works, so that no one may boast."
Mormonism, while affirming the importance of Christ's atonement, also teaches that exaltation—the highest level of eternal blessing—is connected to human obedience, participation in temple ordinances, covenant keeping, and continued faithfulness. The result is a system in which assurance ultimately depends, at least in part, upon one's own performance. The gospel proclaimed by the apostles is entirely different. Our acceptance before God rests not upon what we accomplish but upon what Christ has already accomplished. When Jesus declared from the cross, "It is finished," He announced that the work necessary for our redemption had been completed forever.
The Bible also teaches that there is only one God and that human beings will never become divine in the sense of sharing God's nature or status. Through Christ, believers become adopted children of God, heirs with Christ, and participants in the blessings of His kingdom. Yet we remain redeemed creatures forever. We will worship God throughout eternity, not become gods ourselves. The biblical hope is not exaltation to deity but everlasting fellowship with the one true God through Jesus Christ.
Another concern is the way Mormonism redefines familiar biblical language. Words such as grace, salvation, priesthood, revelation, and gospel are all used, but often with meanings that differ significantly from historic Christian doctrine. This can create confusion because conversations may appear to reveal agreement when, in reality, the underlying beliefs are very different. For this reason, Christians should listen carefully, ask thoughtful questions, and always return to the teaching of Scripture as the final authority.
Our response to Latter-day Saints should never be one of arrogance or hostility. We should remember that we ourselves are saved solely by God's grace. We did not discover the truth because we were wiser or more deserving than anyone else. God opened our eyes through His Word and His Spirit. That reality should produce humility, compassion, and patience as we engage those who believe differently. We should build genuine friendships, listen respectfully, answer questions honestly, and consistently point people to the sufficiency of Christ and the authority of Scripture.
The church must also resist the temptation to minimize these doctrinal differences in the name of unity. While Christians should seek peaceful relationships with everyone, genuine spiritual unity can exist only where there is agreement about the biblical gospel. The apostles consistently warned the early church against false teachers because what we believe about Christ and salvation has eternal consequences. Love requires clarity. It is not loving to suggest that contradictory gospels are equally valid.
The good news is that God's grace reaches people from every religious background. Many former Latter-day Saints have come to know the joy of the biblical gospel after discovering that Christ's finished work is completely sufficient. They no longer live under uncertainty, wondering whether they have done enough. Instead, they rest in the assurance that their acceptance before God depends entirely upon the righteousness of Jesus Christ.
For that reason, I believe Mormonism is false—not because I dislike those who follow it, but because I believe the Bible is God's final revelation and Jesus Christ is the only Savior revealed in its pages. Out of love for my Mormon neighbors, I desire that they come to know the true Christ, trust in His finished work alone, and experience the freedom and assurance that belong to everyone who is justified by grace through faith in Him.
