Mormonism is not Christian, but can appear to be. At the core, Christianity is built on belief in Jesus Christ as revealed in the Bible alone. There we see that Jesus is both fully God and fully man and is the only way to be saved from our sins and receive eternal life—by faith alone and not by human works in any measure. Mormonism can’t be Christian and deny those basic truths, and, unfortunately, the Mormon faith does deny those truths, mixing them with lies. Though Mormons claim to believe in Jesus Christ, the “Jesus” they are speaking about is not the Jesus of history. They do not believe Jesus was God and instead say He was a created being, which would mean His sacrifice would be for Himself alone and could not pay for all sins for all time and save all of us by faith. As God, Jesus can offer an infinite sacrifice to cover us all, but the Mormon faith denies that reality.
Mormonism also teaches that salvation is by both faith and works, meaning people must believe but must also do things to be saved, which is very unbiblical, as God’s Word says, “For by grace you have been saved through faith. And this is not your own doing; it is the gift of God” (Ephesians 2:8). This means that any attempt to follow the Mormon faith will take us away from genuine salvation in Christ alone by faith alone. Finally, the Book of Mormon you received is evidence that Mormonism is unbiblical. God’s Word says, “But even if we or an angel from heaven should preach to you a gospel contrary to the one we preached to you, let him be accursed” (Galatians 1:8). Paul was warning the early church that there was no more to be added to the message of salvation they had received about Jesus. But the Mormon faith claims that Joseph Smith received an additional revelation from an angel in the 1800s that can be added to the Scriptures, and that is very unbiblical. So Mormons may give you a Bible and a Book of Mormon, but their hope is that the Book of Mormon’s lies will teach you to interpret the Bible in a false way (the way many of them have learned to interpret it, sometimes without realizing it is wrong). Ultimately, following the genuine Jesus of history (who is God Himself) will require any true believer to walk away from Mormonism and trust in Christ alone for salvation.
