Aside from the Book of Mormon not containing the so-called “precious truths” that were allegedly lost, of LDS essential doctrines (e.g., LDS polytheism [i.e., the idea that many true Gods exists, technically, henotheism], Exaltation, Eternal Progression, the idea of Aaronic and Melchizedek priesthoods, sealing, eternal marriage et al.), the LDS doctrine has always rejected the biblical revelation of Christ.        

In spite of who authored it, the Book of Mormon contains significant contradictions both historical and theological (and logical). Of the abounding material objectively demonstrating this (from its inception in 1830), we have documented a vast amount of erroneous teaching contained in the LDS so-called scriptures (i.e., the Book of Mormon, Doctrine and Covenants, and Pearl of Great Price).

Also, my friends at Institute for Religious Research have provided a simple short article, Seven Contradictions Between The Book of Mormon and the Bible. Although, as pointed out above, many of the fundamental heresies of the LDS Church such as polytheism and Exaltation, which are post-Book of Mormon, this article addresses seven significant false LDS doctrines, which are in fact currently contained in the Book of Mormon.

In fact, it is easily proven that Smith’s early teachings as contained in the Book of Mormon (and early sections of D&C) controvert present- day LDS theology on many accounts. See Early Teachings of Joseph Smith and the Book of Mormon, which Contradict Present- day LDS Theology – See Early Teachings of Joseph Smith.

Although there are many more contradictions and factual errors in the Book of Mormon (and in the other LDS scripture) than seven, they sufficiently and objectively demonstrate that the Book of Mormon is untrustworthy patently contradicting God’s revelation contained in the biblical content. See our expanded article on the Book of Mormon here Book of Mormon

Note, Aside from the seven contradictions briefly listed below by IRR (and many others can be shown), one additional Book of Mormon false teaching is its repeated affirmation of Modalism, that is,  Oneness theology – see Modalism and the Book of Mormon 

IRR article:

There are many serious objections to the claim of Joseph Smith and the LDS church that the Book of Mormon is divinely inspired Latter-day scripture supplemental to the Bible.* However, none are more significant than the numerous contradictions between Book of Mormon teaching and the Bible. This list is illustrative only, not exhaustive.

(1) The Book of Mormon teaches that little children are not capable of sin because they do not have a sinful nature (Moroni 8:8). In contrast, the Bible in Psalm 51:5 clearly teaches that we have a sinful nature from birth: “Surely I was sinful at birth, sinful from the time my mother conceived me” (NIV). (This does not mean that those who die in infancy are lost.**)

(2) 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 2:23-25). In contrast, the Bible specifically declares that Adam’s transgression was a sinful act of rebellion that unleashed the power of sin and death in God’s perfect world (Romans 5:12; 8:20-21). There is no Biblical support for the view that Adam and Eve could only fulfill the command to “be fruitful and multiply” (Genesis 1:28) by disobeying God’s command regarding the forbidden fruit (Genesis 2:17). The Book of Mormon teaching that these divine commands are contradictory, and that God expected Adam and Eve to figure out that in reality He wanted them to break the latter command (“of the tree of the knowledge of good and evil, thou shalt not eat of it”) in order to keep the former (“be fruitful and multiply”), has no basis in logic or the Biblical text, and attributes equivocation to God.

 

(3) The Book of Mormon teaches that black skin is a sign of God’s curse, so that white-skinned people are considered morally and spiritually superior to black-skinned people (2 Nephi 5:21). In contrast, the Bible teaches that God “made of one blood all nations of men” (Acts 17:26, KJV), that in Christ distinctions of ethnicity, gender and social class are erased (Galatians 3:28), and that God condemns favoritism (James 2:1). [NOTE: See our article, Mormonism and Black Skin, for an documented and expanded look at the LDS views both delineated in the LDS scriptures and by way of sermon or statements by LDS General Authorities (LDS Presidents, Apostles, etc.) regarding people with dark skin, which the LDS has seen, for almost 200 years, as “cursed”].      

(4) The Book of Mormon teaches that, “it is by grace that we are saved, after all we can do” (2 Nephi 25:23; see also Moroni 10:32). In contrast, the Bible teaches that apart from Christ we are dead in sin (Ephesians 2:1,5) and unable to do anything to merit forgiveness and eternal life. Salvation is wholly of grace (Ephesians 2:8-9; Romans 11:6; Titus 3:5-6), not by grace plus works. Good works are a result, not the basis, of a right relationship with God (Ephesians 2:10).

(5) According to the Book of Mormon, about 600 years before Christ, a Nephite prophet predicted that “many plain and precious parts” (1 Nephi 13:26-28) would be removed from the Bible. In contrast, from the Bible it is clear that during His earthly ministry, Jesus himself constantly quoted from the Old Testament Scriptures, and showed full confidence in their completeness and accurate transmission as they had survived down to His time. Jesus declared that “heaven and earth shall pass away, but my words shall not pass away” (Mark 13:31; see also Matthew 5:18), and promised His disciples who were to pen the New Testament that the Holy Ghost “shall teach you all things, and bring all things to your remembrance, whatsoever I have said unto you” (John 14:26); Jesus further promised the apostles that they would “bring forth fruit, and that your fruit should remain” (John 15:16). These promises clearly imply that the fruit of the apostles — the New Testament Scriptures and the Christian church — would endure.

(6) According to a Book of Mormon prophecy (Helaman 14:27), at the time of Christ’s crucifixion “darkness should cover the face of the whole earth for the space of three days.” In contrast, the New Testament gospel accounts declare repeatedly that there was darkness for only three hours while Jesus was on the cross (Matthew 27:45; Mark 15:33; Luke 23:24).

(7) The Book of Mormon teaches that there were many high priests serving at the same time (Mosiah 11:11; Alma 13:9-10; 46:6,38; Helaman 3:25) among the Book of Mormon people who are described as Jewish immigrants from ancient Israel who “kept the law of Moses” (e.g., 2 Nephi 25:10; Jacob 4:5; Jarom 1:5). In contrast, it is clear from the Bible that only one individual at a time occupied the office of high priest under the Old Testament dispensation (see, for example Leviticus 21:10; Matthew 26:3; Hebrews 8:6-7). (The mention in Luke 3:2 of “Annas and Caiaphas being the high priests” is not a real exception — in Christ’s time Israel was under the domination of the Romans, who intervened to change the high priest at will. See John 18:13, which describes Annas as “father-in-law to Caiaphas, which was the high priest that same year.”)

CONCLUSION: The contradictions between the Book of Mormon and the Bible constitute a most serious obstacle to accepting the Book of Mormon as Latter-day scripture supplemental to the Bible. The Bible came first, not the Book of Mormon. And whereas the Bible is organically linked to the earthly ministry of Jesus Christ by extensive surviving manuscript evidence going back as far as A.D. 125-30, the Book of Mormon is wholly lacking in any such evidences of ancient origin. Is it not reasonable, therefore, to make the Bible the standard for judging the Book of Mormon, and not the other way around? If we accept the Bible as our “measuring stick” for spiritual truth, the Book of Mormon must be rejected.

 

Modalism (Oneness Theology) in the Book of Mormon:

 

As a matter of historical recoded, Leader and Founder, and first so-called Prophet and President of the Mormon Church Joseph Smith could not keep consistent in his theology. For example on the nature of God, he went from ‘one God’ (Book of Mormon [cf. Alma 11:44; 2 Nephi 31:21, Testimony of the (so-called) Three Witnesses, early sections of D&C, Book of Abraham], to Modalism (sections in the Book of Mormon [cf. Mosiah 15:1-5; Ether 3:14; Alma 11:38-39], to flat out polytheism (cf. Teachings of the Prophet Joseph Smith, pp. 345-347), which the LDS Church embraces today. See Early Teachings of Joseph Smith and the Book of Mormon, which Contradict Present- day LDS Theology

 

Modalism-  https://christiandefense.org/oneness/modalism-and-the-book-of-mormon/

 

In terms of Modalism, Joseph Smith did not understand the difference between the doctrine of the Trinity and the teachings of Modalism. Modalism (also referred to as Oneness theology) was the second century heresy that asserted that God is unitarian (unipersonal), that is, God existing as one person that reveals himself in different modes, manifestations or dimensions, rejecting the Trinity.

In other words, in Oneness thinking, since God is one, and Jesus is called God, Jesus then is the Father, Son, and the Holy Spirit—not three persons, rather three manifestations or modes. Oneness doctrine teaches then that the unipersonal God (named Jesus) has two natures, divine being the Father and human being the Son. Thus, in this doctrine, Jesus acts sometimes as the Son (human) and sometimes as the Father (God) and yet other times the Holy Spirit.- –  For more details on Oneness see: Oneness Theology. 

So, what does Modalism have to do with Joseph Smith? Answer: the Book of Mormon teaches both Trinitarian and Modalism. However, I find that the Book of Mormon is more modalistic than Trinitarian, though. First, observe these decidedly modalistic passages in the Book of Mormon.

 

Mosiah 15. The introduction of Mosiah chapter 15 reads: How Christ is both the Father and the Son–He shall make intercession and bear the transgression of his people. . . .” Then, starting at verse 1 through verse 5, note the heighted areas:

And now Abinadi said unto them: I would that ye should understand that God himself [the Father] shall come down among the children of men, and shall redeem his people. 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. The Father because he was conceived by the power of God; and the Son, because of the flesh; thus becoming the Father and Son. And they are one God, yea, the very Eternal Father of heaven and earth. And thus the flesh becoming subject to the Spirit, or the Son to the Father, being one God. . . . (Mosiah 15:1-5).

 

That Jesus is the Father, is a teaching that is clearly taught in Smith’s, Book of Mormon

 

Ether 3:14: “Behold, I am the he who was prepared from the foundation of the world to redeem my people. Behold, I am the Father and the Son. . . .”

Alma 11:38-39: “Now Zeezrom saith again unto him: Is the Son of God the very Eternal Father? And Amulek said unto him: Yea, he is the very Eternal Father of heaven and of earth, and all things which in them are; he is the beginning and the end, the first and the last.”

Amazingly, a mere five verses later (11:44), we find a contradictive implication of what resembles the orthodox doctrine of the Trinity:

but every thing shall be restored to its perfect frame, as it is now, or in the body, and shall be brought and be arraigned before the bar of Christ the Son, and God the Father, and the Holy Spirit , which is one Eternal God. . . .”

 2 Nephi 31:21: “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. Amen.”

Further, the “Testimony of the three Witnesses” do not agree with the present-day LDS teaching (three separate Gods). Rather, the converse is stated: “And honor be to the Father, and to the Son, and to the Holy Ghost, which is one God” (Book of Mormon, Introduction). The nature of God is not the only doctrine that Joseph Smith changed in his lifetime. However, the true God of biblical revelation is the triune God and thus, a denial of the nature of God is a denial of Christ and His gospel (cf. Isa. 43:10; Hosea 6:6; John 8:24, 58; 5:24; 17:3; 1 John 5:20).
