What do Mormons believe about God, Jesus, and salvation? A respectful but honest examination of LDS theology, the Book of Mormon, and why biblical Christianity differs from Mormon teaching.
A Conversation Worth Having
If you’re reading this, you might be:
- A Christian trying to understand what your Mormon friend or neighbor believes
- A Mormon (or Latter-day Saint) curious about what Christians think of your faith
- Someone investigating both Christianity and Mormonism, trying to discern truth
This article is written with respect for Mormons as people—many of whom are kind, moral, family-oriented, and sincere in their faith. But respect for people doesn’t require agreement with their theology.
Christianity and Mormonism make mutually exclusive truth claims. Both cannot be right. One is true, or neither—but not both.
This article examines those differences honestly, not to attack Mormons as individuals, but to help you think critically about what you believe and why you believe it.
If you’re a Christian, this will equip you to have gracious conversations with Mormon friends.
If you’re a Mormon, this will challenge you to examine whether the LDS church’s claims hold up under scrutiny.
The Core Question: Was Christianity Lost?
The foundational claim of Mormonism is this:
After the death of the apostles, true Christianity was completely lost from the earth. The church fell into total apostasy. God’s Word was corrupted. Priesthood authority vanished. For nearly 1,800 years, there was no valid Christianity anywhere on earth—until Joseph Smith restored it in the 1820s-1840s.
This is called the Great Apostasy.
Why This Claim Matters
If the Great Apostasy is true, then:
- Jesus and the apostles failed in their mission to establish the church
- God was either unable or unwilling to preserve His Word
- No Christian for 1,800 years had access to true doctrine
- The New Testament we have today is unreliable
- Joseph Smith is necessary for salvation
But if the Great Apostasy is false, then:
- The LDS church’s entire foundation collapses
- Joseph Smith’s revelations are unnecessary (at best) or false (at worst)
- Biblical Christianity has been true all along
Everything hinges on this question: Did Christianity disappear and need to be restored?
What the Bible Says About the Church’s Survival
Jesus’ Promise
In Matthew 16:18, Jesus said:
“I will build My church, and the gates of Hades shall not prevail against it.”
Jesus promised His church would endure. Not that it would be perfect. Not that there wouldn’t be corruption or false teachers. But that the gates of hell would not destroy it.
If Mormonism is right, Jesus was wrong. The gates of hell did prevail—for 1,800 years.
The Holy Spirit’s Presence
Jesus also promised in John 14:16-17:
“I will ask the Father, and He will give you another Helper, that He may be with you forever; that is the Spirit of truth… He abides with you and will be in you.”
The Holy Spirit was given to guide the church into all truth (John 16:13). If the church completely apostatized, where was the Holy Spirit? Did He fail? Did He abandon the church?
The Mormon claim of total apostasy implies the Holy Spirit was powerless or absent for 1,800 years. That directly contradicts Jesus’ promise.
Paul’s Confidence
Paul wrote in Ephesians 3:21:
“To Him be glory in the church and in Christ Jesus throughout all generations, forever and ever. Amen.”
Paul expected the church to glorify God throughout all generations—not to vanish for 1,800 years and be resurrected by Joseph Smith.
The Historical Record
History shows an unbroken chain of Christian witness from the apostles to today:
- 2nd century: Ignatius, Polycarp (disciples of the apostles) wrote letters defending the faith
- 3rd-4th centuries: Church councils defined core doctrines (Trinity, deity of Christ, canon of Scripture)
- 5th-15th centuries: Monasteries preserved Scripture; missionaries spread the gospel
- 16th century: Reformation recovered biblical truth from medieval corruptions
Was the medieval church corrupt in places? Yes. Were there false teachings? Absolutely. But total apostasy? No. True believers existed in every generation, preserving and proclaiming the gospel.
The Great Apostasy is not supported by Scripture or history.
The Four Mormon Scriptures: Are They Equal?
Mormonism claims four sources of divine revelation:
- The Bible (King James Version, “insofar as it is translated correctly”)
- The Book of Mormon (published 1830)
- Doctrine and Covenants (collected revelations, finalized 1835+)
- Pearl of Great Price (published 1851)
The LDS church teaches these are all equally inspired by God and carry equal authority.
The Logical Problem
If God inspired all four books, they should never contradict each other—because God does not lie (Titus 1:2) and His Word is unchanging (Hebrews 13:8).
But here’s the test: Which book came first?
The Bible spans over 1,500 years of history (from Moses ~1400 BC to John ~95 AD or earlier). It was completed nearly 1,800 years before Joseph Smith was born.
The Book of Mormon, Doctrine and Covenants, and Pearl of Great Price are all 19th-century texts.
Doesn’t it make sense to judge the newer revelations by the older one?
If a 19th-century book contradicts a 1st-century book—and both claim to be from God—one of them is wrong. And since God’s Word is eternal and unchanging, the original revelation (the Bible) takes precedence.
Where Mormon Scripture Contradicts the Bible
Let’s examine key doctrines where LDS teaching contradicts biblical Christianity:
1. The Nature of God
The Bible teaches:
- God is eternal spirit (John 4:24)
- God is unchanging (Malachi 3:6; James 1:17)
- God has always been God (Psalm 90:2)
- There is one God (Deuteronomy 6:4; Isaiah 43:10)
Mormonism teaches (from LDS scripture and prophets):
- God the Father has a physical body of flesh and bones (Doctrine and Covenants 130:22)
- God was once a man who progressed to become God (taught by Joseph Smith and Brigham Young)
- There are many gods (polytheism)
- Faithful Mormons can become gods themselves
This is incompatible with biblical revelation. The God of the Bible is not an exalted man. He is the eternal, uncreated Creator who has always existed as God.
2. The Nature of Jesus Christ
The Bible teaches:
- Jesus is fully God (John 1:1; Colossians 2:9)
- Jesus is the eternal Son (Hebrews 1:8-12)
- Jesus is one with the Father in essence (John 10:30)
Mormonism teaches:
- Jesus is the spirit brother of Lucifer (both are created spirit children of Heavenly Father)
- Jesus earned His divinity through progression
- Jesus is “a god” but not the same as the Father
This denies the biblical doctrine of the Trinity and reduces Jesus to a created being—which is exactly what early church councils condemned as heresy (Arianism).
3. Salvation
The Bible teaches:
- Salvation is by grace alone through faith alone (Ephesians 2:8-9)
- Works are the result of salvation, not the cause (James 2:17)
- Salvation is a gift, not earned (Romans 6:23)
Mormonism teaches:
- Salvation requires faith + works + ordinances (baptism, temple endowment, etc.)
- Exaltation (becoming a god) requires temple marriage and obedience to LDS teachings
- “We believe that through the Atonement of Christ, all mankind may be saved, by obedience to the laws and ordinances of the Gospel“ (Articles of Faith 1:3)
This is works-based righteousness, which Paul explicitly condemned:
“If righteousness comes through the Law, then Christ died needlessly” (Galatians 2:21).
If you must earn your salvation through obedience and ordinances, the cross was insufficient. Mormonism adds human effort to Christ’s finished work—which means it’s a different gospel.
4. The Bible’s Reliability
The Bible teaches:
- Scripture is inspired by God and inerrant (2 Timothy 3:16)
- God’s Word is eternal and will never pass away (Matthew 24:35)
- The Holy Spirit preserves God’s Word (John 14:26)
Mormonism teaches:
- The Bible has been corrupted and is unreliable (“insofar as it is translated correctly”)
- Many “plain and precious truths” were removed from the Bible (1 Nephi 13:26-28)
- Joseph Smith made over 3,400 changes to the King James Bible in his “Joseph Smith Translation”
The Problem with This Claim
If the Bible was corrupted, who corrupted it? When? How?
Mormons can’t answer this specifically—because manuscript evidence proves the opposite.
We have:
- 5,800+ Greek New Testament manuscripts
- Early manuscripts dating to within decades of the originals
- The Dead Sea Scrolls proving Old Testament stability over 1,000+ years
Textual scholars—even non-Christian ones—agree: the Bible has been preserved with extraordinary accuracy. The differences between manuscripts are minor (spelling, word order) and don’t affect any major doctrine.
If God couldn’t preserve His Word, how can Mormons trust He preserved the Book of Mormon?
The claim that the Bible is corrupted undermines all claims to divine revelation—including Mormon scripture.
Joseph Smith’s Revisions to the Bible
Joseph Smith claimed God revealed to him that the King James Bible was corrupted, and he was called to restore it. He made over 3,400 changes—not translations from better manuscripts, but claimed revelations.
Examples of Joseph Smith’s Changes
Genesis 50:24-38 — Smith added 14 verses predicting his own coming: “And that seer will I bless… and his name shall be called Joseph, and it shall be after the name of his father” (referencing Joseph Smith Jr., son of Joseph Smith Sr.)
This is not in any Hebrew manuscript. Smith invented it.
John 1:1 — Smith changed:
- “In the beginning was the Word” to “In the beginning was the gospel”
This changes the meaning entirely. The original Greek identifies Jesus as the eternal Word (Logos). Smith’s change obscures Jesus’ deity.
Why This Matters
If Joseph Smith had genuine divine authority, his changes would align with ancient manuscripts. They don’t.
If Joseph Smith could add and alter Scripture at will, why should we trust him more than the 5,800+ manuscripts we already have?
Claiming the Bible is corrupt while producing your own “corrected” version is circular reasoning. It assumes Smith’s authority to prove Smith’s authority.
The Book of Mormon: Archaeological and Historical Problems
The Book of Mormon claims to be an ancient record of civilizations in the Americas from ~2200 BC to 421 AD, written on gold plates and translated by Joseph Smith.
The Archaeological Problem
If the Book of Mormon is historical, we should find:
- Evidence of large-scale civilizations (millions of people) in ancient America
- Hebrew or Reformed Egyptian writing in the Americas
- Middle Eastern animals mentioned in the Book of Mormon (horses, cattle, sheep, goats, elephants, steel, chariots, silk)
None of this exists. After nearly 200 years of searching:
- No archaeological evidence supports Book of Mormon geography
- No ancient Hebrew inscriptions found in the Americas
- Horses, cattle, elephants, steel, chariots, and silk did not exist in pre-Columbian America
The Smithsonian Institution and National Geographic have both stated they do not use the Book of Mormon in archaeological research because it has no historical value.
The DNA Problem
The Book of Mormon claims Native Americans are descendants of Israelites (Lamanites) who migrated to America around 600 BC.
DNA testing proves Native Americans are not of Middle Eastern descent. They are of East Asian origin, having migrated across the Bering Strait.
In response, the LDS church quietly changed the Book of Mormon’s introduction (in 2006) from:
- “the Lamanites… are the principal ancestors of the American Indians”
To:
- “the Lamanites… are among the ancestors of the American Indians”
This is a tacit admission the original claim was false.
The Test: Older Revelation Judges Newer Revelation
Here’s the principle:
If God inspired both the Bible and the Book of Mormon/D&C/Pearl of Great Price, they must agree—because God does not contradict Himself.
Where they disagree, the older revelation (the Bible) takes precedence, because:
- It came first (1,800 years before Joseph Smith)
- It has manuscript evidence proving its preservation
- It has archaeological and historical confirmation
- Jesus and the apostles affirmed it as God’s Word
Joseph Smith’s revelations fail this test. They contradict:
- The nature of God (eternal spirit vs. exalted man)
- The nature of Christ (eternal God vs. created spirit brother of Satan)
- Salvation (grace alone vs. works + ordinances)
- The church’s survival (enduring vs. total apostasy)
When you must choose between Jesus Christ and Joseph Smith, believe Jesus Christ.
A Word to Mormons: Test Your Faith
If you’re a Mormon, we ask you to consider these questions honestly:
1. Would God Let His Word Be Corrupted?
If the Bible was corrupted beyond reliability, does that mean:
- God was too weak to preserve His Word?
- God was too uncaring to protect His people from false doctrine?
Either option makes God untrustworthy. If He couldn’t (or wouldn’t) preserve the Bible, how can you trust Him to preserve the Book of Mormon?
2. Why Does the Book of Mormon Contain No Archaeological Evidence?
If millions of people lived in advanced civilizations in the Americas, where are the ruins, the writings, the artifacts? Why does every piece of evidence point to East Asian origins for Native Americans, not Middle Eastern?
3. Why Did Joseph Smith Make False Prophecies?
Deuteronomy 18:21-22 says:
“When a prophet speaks in the name of the LORD, if the thing does not come about or come true, that is the thing which the LORD has not spoken. The prophet has spoken it presumptuously.”
Joseph Smith prophesied:
- The temple would be built in Independence, Missouri “in this generation” (D&C 84:4-5) — It wasn’t
- A man named Baurak Ale living on the moon, dressed like a Quaker (recorded by multiple witnesses) — Obviously false
- The Civil War would end in the slaves rising up and causing the “full end of all nations” (D&C 87) — Didn’t happen
A true prophet’s words always come true. Joseph Smith’s didn’t.
4. Are You Trusting Joseph Smith or Jesus?
Jesus said: “I am the way, and the truth, and the life; no one comes to the Father but through Me” (John 14:6).
Not through Joseph Smith. Not through temple ordinances. Not through LDS priesthood authority. Through Jesus alone.
If Joseph Smith’s revelations contradict Jesus’ words, who will you believe?
For Christians: How to Talk to Mormon Friends
If you have Mormon friends or family, approach conversations with:
1. Respect
Mormons are often kind, moral, and sincere. Don’t mock them. Don’t be condescending. Engage their beliefs, not their character.
2. Ask Questions
Instead of lecturing, ask:
- “How do you reconcile the Book of Mormon’s claim about Native Americans with DNA evidence?”
- “If the Bible was corrupted, how can we trust any revelation—including Joseph Smith’s?”
- “Do you believe Jesus’ promise in Matthew 16:18 that the gates of hell would not prevail against His church?”
Questions invite them to think critically without feeling attacked.
3. Share the Gospel
The gospel is good news: Jesus Christ, the eternal Son of God, died for your sins, rose from the dead, and offers salvation by grace through faith alone.
You don’t need Joseph Smith. You don’t need temple ordinances. You don’t need to become a god.
You need Jesus. He is enough.
Conclusion: Choose the True Jesus
Mormonism and biblical Christianity both claim to follow Jesus. But they describe different Jesuses:
The Jesus of the Bible:
- Eternal God
- Creator of all
- Savior by grace alone
- Sufficient for salvation
The Jesus of Mormonism:
- Created spirit brother of Lucifer
- Exalted man who earned godhood
- Savior through grace + works + ordinances
- Insufficient without Joseph Smith’s restoration
These are not the same.
Paul warned in Galatians 1:8:
“But even if we or an angel from heaven should preach a gospel contrary to the one we preached to you, let him be accursed!”
The Mormon Jesus is another Jesus—not the Jesus of the apostles, not the Jesus of the Bible, not the Jesus who saves.
If you’re trusting Joseph Smith’s Jesus, you’re trusting a false christ.
Turn to the real Jesus—the one revealed in Scripture, affirmed by history, and alive today. He doesn’t need restoration. He never left.
How to Come to the Real Jesus
If you’re a Mormon and this article has stirred doubt, or if you’re investigating Mormonism and want to know the true Jesus, here’s how to begin:
1. Pray for Truth
Ask God to reveal Himself—not through feelings, but through His Word. Feelings can mislead. Scripture does not. Study.
2. Read the Bible
Start with the Gospel of John. Don’t read it through Mormon lenses. Let it speak for itself. Ask: “What is this text actually saying?”
3. Trust Jesus Alone
Salvation is not through a church, a prophet, or ordinances. It’s through Jesus Christ alone.
Pray: “Jesus, I’ve been trusting in the wrong things. I’ve believed teachings that contradict Your Word. I turn from them now. I believe You are the eternal Son of God, that You died for my sins, and that You rose from the dead. I trust in You alone for salvation—not Joseph Smith, not the LDS church, not my works. Save me. Forgive me. Lead me into truth. In Your name, amen.”
4. Find a Biblical Church
Leave the LDS church and find a Bible-believing church where the gospel is preached clearly: salvation by grace alone, through faith alone, in Christ alone.
Frequently Asked Questions
Q: Aren’t Mormons Christians?
A: Mormons call themselves Christians, but their core doctrines contradict Christianity:
- They deny the Trinity
- They teach a different Jesus (created being, not eternal God)
- They teach a different gospel (salvation by works + grace, not grace alone)
- They add extra-biblical scripture as equal to the Bible
Christianity is defined by apostolic teaching (Acts 2:42). Mormonism deviates from that teaching on fundamental issues. Calling yourself Christian doesn’t make it so—doctrine matters.
Q: Don’t Mormons have good families and values?
A: Yes, many Mormons are kind, moral, family-oriented people. But good behavior doesn’t determine truth. Many Muslims, Hindus, and atheists are also kind and moral. The question isn’t “Are Mormons nice?” It’s “Is Mormonism true?”
Q: What about the “burning in the bosom” testimony Mormons experience?
A: Mormons often cite feelings (a “burning in the bosom”) as proof the Book of Mormon is true. But feelings are not reliable indicators of truth. People in every religion—Islam, Hinduism, Buddhism—report strong spiritual feelings. If feelings prove truth, then all religions are true (which is logically impossible).
Truth is determined by evidence and consistency with God’s revealed Word, not subjective feelings.
Q: Should I still be friends with Mormons?
A: Absolutely. Love them, serve them, be a good neighbor and friend. But love them enough to tell them the truth—that Joseph Smith’s teachings contradict Jesus’ teachings, and they must choose whom to follow.

Original tract: If Joseph Smith’s vision is right, there was no valid Christianity on the earth for 1,800 years. This means Christ and the Apostles failed in their efforts to establish a meaningful church. Their work unraveled into apostasy soon after the physical deaths of the Apostles and not even God could preserve His Word for earnest seekers until Joseph Smith resurrected it in the 1800’s. Mormonism stands on four revelations: The Book of Mormon, Doctrine and Covenants, Pearl of Great Price, and a deeply-edited version of the King James Bible (insofar as it is correctly translated.) If you’re following Mormon doctrine, ask yourself: Didn’t the same God inspire all four books? Are they all of equal validity? Does God ever lie? Can God be relied upon at all times? Which is the oldest of these four texts? [Answer: Bible, which spans a period of over 5,000 years.] Don’t you think it’s proper to judge the younger revelations by the oldest revelation, because God—who cannot lie—will tell us the straight story from the very beginning? And if the other books don’t agree with the oldest book, then obviously something must be wrong with the younger books, right? Smith made over 3,400 changes to God’s Word. Believing the Bible was corrupted means either God could not or would not protect His Word. This either implies God is inept and can be thwarted by lowly mortals or that He must be immoral, allowing His people to follow corrupted commands. When deciding between Joseph Smith and Jesus Christ, please believe Jesus Christ. Pray for God’s clarity and wisdom and ask for His revelation today. levaire.com/what-do-mormons-believe/
