Tested by Scripture

Contradictions with the Bible

Where the Book of Mormon contradicts the King James Bible — and where it even contradicts the LDS Church's own teachings.

The Bible instructs believers to test all things by comparing them with the established word of God. The Bereans were commended because "they received the word with all readiness of mind, and searched the scriptures daily, whether those things were so" (Acts 17:11). When we apply this standard to the Book of Mormon, we find numerous significant problems.

What makes these contradictions especially notable is that in several cases, the Book of Mormon actually agrees with the Bible against what the LDS Church teaches today. This means modern Mormonism has departed not only from biblical teaching, but from its own founding scripture.

Contradiction 01

God Was Once a Man?

The LDS Church teaches that God the Father was once a mortal man who progressed to godhood. Fifth LDS President Lorenzo Snow summarized this in his famous couplet: "As man now is, God once was; as God now is, man may be." Joseph Smith taught the same in his 1844 King Follett Discourse, declaring: "God himself was once as we are now, and is an exalted man."

Yet the Book of Mormon itself teaches the exact opposite. If God is "unchangeable from all eternity to all eternity," He could never have been a mere man who later became God. Joseph Smith published these words in 1830, then directly contradicted them fourteen years later when he declared, "We have imagined and supposed that God was God from all eternity. I will refute that idea."

The Bible is equally clear that God has always been God and has never been a man.

What the Book of Mormon Says
For I know that God is not a partial God, neither a changeable being; but he is unchangeable from all eternity to all eternity.(Moroni 8:18)For do we not read that God is the same yesterday, today, and forever, and in him there is no variableness neither shadow of changing?(Mormon 9:9)For behold, God knowing all things, being from everlasting to everlasting.(Moroni 7:22)
What the Bible Says
Before the mountains were brought forth, or ever thou hadst formed the earth and the world, even from everlasting to everlasting, thou art God.(Psalm 90:2)God is not a man, that he should lie; neither the son of man, that he should repent.(Numbers 23:19)Thus saith the LORD the King of Israel, and his redeemer the LORD of hosts; I am the first, and I am the last; and beside me there is no God.(Isaiah 44:6)
Contradiction 02

One God or Many Gods?

LDS theology teaches that there are innumerable gods throughout the universe and that faithful Latter-day Saints can themselves become gods. Joseph Smith declared in his King Follett Discourse: "you have got to learn how to be Gods yourselves ... the same as all Gods have done before you." Brigham Young taught: "The Lord created you and me for the purpose of becoming Gods like Himself."

Yet the Book of Mormon itself teaches a clearly monotheistic view of God. The testimony of the Three Witnesses at the front of the Book of Mormon concludes with an affirmation of one God. Multiple passages throughout the Book of Mormon reinforce this teaching.

The Bible is emphatic that there is one God and no others exist beside Him.

What the Book of Mormon Says
And the honor be to the Father, and to the Son, and to the Holy Ghost, which is one God. Amen.(Testimony of the Three Witnesses)And now, behold, this is the doctrine of Christ, and the only and true doctrine of the Father, and of the Son, and of the Holy Ghost, which is one God, without end.(2 Nephi 31:21)
What the Bible Says
I am the LORD, and there is none else, there is no God beside me.(Isaiah 45:5)Hear, O Israel: The LORD our God is one LORD.(Deuteronomy 6:4)Is there a God beside me? yea, there is no God; I know not any.(Isaiah 44:8)
Contradiction 03

The Fall: Sin or Blessing?

The Book of Mormon teaches that the disobedience of Adam and Eve in eating the forbidden fruit was necessary so that they could have children and bring joy to mankind (2 Nephi 2:22-25). This teaching implies that Adam and Eve, though they "transgressed" God's command, did not truly sin but actually did something noble and necessary.

The Bible teaches the opposite. Adam's act of eating the forbidden fruit was sin, not a praiseworthy "transgression." Through that one act of disobedience, sin and death entered the world and passed upon all of humanity. The curse resulting from the fall increased Eve's pain in childbearing, which indicates she could have borne children before the fall (Genesis 3:16). God had already commanded Adam and Eve to "be fruitful, and multiply" before the fall (Genesis 1:28), demonstrating they did not need to sin in order to have children.

What the Book of Mormon Says
And now, behold, if Adam had not transgressed he would not have fallen, but he would have remained in the garden of Eden ... they would have had no children ... Adam fell that men might be; and men are, that they might have joy.(2 Nephi 2:22-25)
What the Bible Says
Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men, for that all have sinned.(Romans 5:12)For as in Adam all die, even so in Christ shall all be made alive.(1 Corinthians 15:22)And God blessed them, and God said unto them, Be fruitful, and multiply, and replenish the earth.(Genesis 1:28)
Contradiction 04

Saved by Grace After All We Can Do?

The Book of Mormon states: "we know that it is by grace that we are saved, after all we can do" (2 Nephi 25:23). The traditional LDS interpretation of this statement is that human effort and good works are required conditions of salvation alongside God's grace. In LDS theology, salvation (specifically exaltation to the highest degree of the celestial kingdom) requires faith, repentance, baptism by proper authority, receiving the gift of the Holy Ghost, temple ordinances including the endowment and celestial marriage, and ongoing obedience to the commandments.

The Bible teaches a fundamentally different message. Salvation is entirely a gift of God's grace, received through faith alone. Good works are the fruit of salvation, not the root of it. A person who has truly been saved will produce good works as evidence of their new nature in Christ, but those works contribute nothing to earning or maintaining their salvation.

What the Book of Mormon Says
For we labor diligently to write, to persuade our children, and also our brethren, to believe in Christ, and to be reconciled to God; for we know that it is by grace that we are saved, after all we can do.(2 Nephi 25:23)
What the Bible Says
For by grace are ye saved through faith; and that not of yourselves: it is the gift of God: Not of works, lest any man should boast.(Ephesians 2:8-9)Not by works of righteousness which we have done, but according to his mercy he saved us, by the washing of regeneration, and renewing of the Holy Ghost.(Titus 3:5)But to him that worketh not, but believeth on him that justifieth the ungodly, his faith is counted for righteousness.(Romans 4:5)
Contradiction 05

Jesus as Both Father and Son?

The Book of Mormon identifies Jesus as both "the Father and the Son" in multiple places (Mosiah 15:1-5; Mormon 9:12; Ether 3:14), and in many other passages identifies Jesus as "the Father." This confuses the clear biblical distinction between God the Father and God the Son, who are presented throughout the Bible as two distinct persons.

Interestingly, this teaching in the Book of Mormon also contradicts what the LDS Church teaches today. Modern LDS doctrine holds that the Father and the Son are two completely separate and distinct beings with separate physical bodies of flesh and bone. The Book of Mormon's identification of Jesus as "the Father and the Son" more closely resembles the ancient heresy of modalism (the idea that God manifests as different "modes" rather than being three distinct persons), which the LDS Church itself rejects.

What the Book of Mormon Says
And because he dwelleth in flesh he shall be called the Son of God, and having subjected the flesh to the will of the Father, being the Father and the Son.(Mosiah 15:2-3)Behold, I am Jesus Christ. I am the Father and the Son.(Ether 3:14)
What the Bible Says
Grace be with you, mercy, and peace, from God the Father, and from the Lord Jesus Christ, the Son of the Father, in truth and love.(2 John 1:3)And lo a voice from heaven, saying, This is my beloved Son, in whom I am well pleased.(Matthew 3:17)
Contradiction 06

Nephite Priests Without Levites

The Book of Mormon claims that the Nephites faithfully observed the Law of Moses in all things (2 Nephi 5:10; 25:24). Yet neither the Nephites nor the Lamanites had men descended from the tribe of Levi, since Nephi and his brothers came from the tribe of Manasseh (Alma 10:3). Under the Mosaic Law, only men from the tribe of Levi were authorized to serve as priests (Numbers 1:47-53; 3:9-12; 8:6-26).

The Book of Mormon simply ignores this fatal problem. It mentions priests frequently throughout the narrative but never addresses the fact that none of them had the tribal lineage required by the very law they claimed to follow. The book of Hebrews in the Bible makes clear that this tribal requirement was essential to the priesthood: "For it is evident that our Lord sprang out of Juda; of which tribe Moses spake nothing concerning priesthood" (Hebrews 7:14).

What the Book of Mormon Says
And we did observe to keep the judgments, and the statutes, and the commandments of the Lord in all things, according to the law of Moses.(2 Nephi 5:10)
What the Bible Says
And thou shalt appoint Aaron and his sons, and they shall wait on their priest's office: and the stranger that cometh nigh shall be put to death.(Numbers 3:10)For the priesthood being changed, there is made of necessity a change also of the law.(Hebrews 7:12)For it is evident that our Lord sprang out of Juda; of which tribe Moses spake nothing concerning priesthood.(Hebrews 7:14)
Contradiction 07

Multiple Temples

The Bible consistently acknowledges only one temple for Israelite worship (Deuteronomy 12:2-14; 16:2-7), specifically the one located in Jerusalem (1 Kings 8:44, 48; 11:32, 36; 2 Chronicles 7:12, 16). The entire sacrificial system was centered on this one temple, and the tribes of Israel were required to travel to Jerusalem for the annual feasts.

The Book of Mormon, however, describes multiple temples in various locations throughout the land (Alma 16:13; 23:2; 26:29; Helaman 3:9, 14). If the Nephites were truly faithful Israelites who observed the Law of Moses as they claimed, they would have known that God designated only one place for His temple. The building of multiple temples contradicts the clear teaching of the Law they professed to follow.

What the Book of Mormon Says
Yea, and they did build synagogues after the manner of the Jews; and every one that did not belong to the church of God began to persecute those that did belong to the church of God.(Alma 16:13 (references temples))
What the Bible Says
But unto the place which the LORD your God shall choose out of all your tribes to put his name there, even unto his habitation shall ye seek, and thither thou shalt come.(Deuteronomy 12:5)Thou mayest not sacrifice the passover within any of thy gates, which the LORD thy God giveth thee: But at the place which the LORD thy God shall choose to place his name in.(Deuteronomy 16:5-6)

“To the law and to the testimony: if they speak not according to this word, it is because there is no light in them.”

Isaiah 8:20
