The theological and religious teachings of the Book of Mormon are important in three respects. First, its doctrine often agrees with traditional Christian beliefs in sometimes surprising ways and at other times undermines the Bible and traditional Christianity.

When Joseph Smith dictated the Book of Mormon, his religious beliefs were rather typical of “restorationist” thinking within English-speaking Protestantism. Restorationists believed that the Protestant Reformation, though a good step, did not go far enough, and that what was needed was a fresh beginning, a return to primitive Christianity (in some cases with new apostles, miracles, and new revelations). Reflecting this restorationist perspective, the Book of Mormon castigates those Christians who think the Bible is all the scripture needed (1 Nephi 13-14) and rejects the notion that the age of miracles is past (e.g., Mormon 9).

Restorationists were broadly anti-creedal, and some of them vigorously denied the doctrine of the Trinity and argued that Jesus was a perfect man but not deity. Other restorationists, however, did not espouse radically different doctrines of the nature of God, Christ, or the Trinity. The Book of Mormon falls into this latter stream of restorationist thought. It appears to affirm in very explicit terms a Trinitarian theology, asserting repeatedly that the Father, Son, and Holy Ghost are “one God” (2 Nephi 31:21; Mormon 7:7). This language is also found in the Testimony of the Three Witnesses and in one of Joseph’s earliest revelations (D&C 20:28). Some Book of Mormon statements even seem to err on the side of collapsing the personal distinctions within the Trinity, specifically several statements identifying Jesus as both the Father and the Son (Mosiah 15:1-5; Mormon 9:12; Ether 3:14). The Book of Mormon also explicitly teaches that traditional understanding of the attributes of God. For example, it teaches that God has always and eternally been God: “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; see also 7:22; Mosiah 3:5; Alma 13:7; and cf. D&C 20:17).

There are distinctive elements of LDS theology that appeared for the first time in the Book of Mormon. These include, perhaps most notably, the idea that Adam and Eve’s transgression was a good and necessary thing that made it possible for them to have children and experience the full joy God intended (see especially 2 Nephi 2:22-25). In later Mormon theology this idea is taken even further by the notion that human beings existed in heaven before the earth was made and were sent here for the purpose of testing (Abraham 3:21-28).

Second, in important respects, the Book of Mormon’s doctrine is at best lacking key doctrinal elements of Mormonism as it developed following the publication of the Book of Mormon and at worst is clearly inconsistent with later Mormon theology. Theologically, the Book of Mormon differs substantially from the later teachings of Joseph Smith reflected in later parts of Doctrine & Covenants as well as the current official teachings of the LDS Church. In contrast to the staunch Trinitarian-sounding monotheism of the Book of Mormon, toward the end of his life Joseph was teaching that the Father, Son, and Holy Ghost were three Gods. This is implicit in the Book of Abraham, which teaches that a plurality of “Gods” organized the earth (Abraham 4-5), and explicit in Joseph’s last public discourse, the “Sermon at the Grove” on June 16, 1844: “I have always declared God to be a distinct personage, Jesus Christ a separate and distinct personage from God the Father, and that the Holy Ghost was a distinct personage and a Spirit: and these three constitute three distinct personages and three Gods.”1

Similarly, in contrast to the Book of Mormon’s affirmation that God is eternally God, Joseph claimed in another 1844 sermon, the King Follett Discourse, to “refute that idea”:

“We have imagined and supposed that God was God from all eternity. I will refute that idea….”

Mainstream Mormon theology ever since 1844 has maintained that God has not always been God, but was a mortal man who progressed his way to become a God—and that we mortals can do the same. Thus, these differences between Book of Mormon doctrine and Joseph Smith’s later theology are not incidental, but reflect a shift in Joseph’s thinking to an entirely different worldview in which Godhood is an open category into which our God himself entered and to which human beings may also aspire—another idea missing from the Book of Mormon.2

Here is a list of the major aspects of contemporary Mormon belief and religious practice that are completely absent from the Book of Mormon: 

  • Plurality of gods
  • God the Father having a physical body
  • God the Father having once been a mortal man
  • Heavenly mother
  • Humans preexisted as spirits in heaven
  • Eternal progression
  • Celestial marriage
  • Baptism for the dead
  • Three heavenly kingdoms or degrees of glory

Third, the theological and religious issues that dominate the Book of Mormon are clearly inconsistent with its supposed ancient context and obviously reflect Joseph Smith’s nineteenth-century environment. Consider the following list of teachings of the Book of Mormon, all of which were part of the Anglo-American cultural context in which Joseph lived: 

  • Confusion about what the Bible teaches is the result of many plain and precious things being removed from the Bible, resulting in widespread apostasy in Christianity (1 Nephi 13-14).
  • Everyone must be baptized to be saved (2 Nephi 9:23-24). People before the coming of Christ were also required to be baptized (2 Ne. 31:4-12; Mosiah 18:10-17; 26:4, 22; etc.).
  • Believers on earth before the time of Jesus were saved through faith in Jesus Christ, because the prophets spoke explicitly about Jesus by name (e.g., 2 Nephi 25:13-20).
  • There should be no paid clergy (2 Ne. 26:29-31; Mosiah 27:5; Alma 30:32-35).
  • The Father, Son, and Holy Ghost are one God (2 Nephi 31:21; Mormon 7:7).
  • Wearing “costly apparel” is a dangerous indulgence of pride (Jacob 2:13; Alma 1:6, etc.).
  • The doctrine that everyone will be saved (universalism) is false (e.g., Alma 1:4).
  • Skeptical atheists attack the Christian faith (Alma 30).
  • The (Calvinist) doctrine of election is bad (Alma 31:15-18, 24-25).
  • There is an intermediate state between death and resurrection in which righteous spirits are happy in paradise and the wicked are in outer darkness (Alma 40).
  • America as a land of freedom is a fulfillment of prophecy (3 Nephi 21).
  • God revealed the gospel in ancient times in both hemispheres, even sending Jesus to the Nephites to preach the gospel to them (3 Nephi 11-27).
  • A church should not be known by the name of any man except Christ (3 Ne. 27:7-8).
  • The time of miracles and revelations is not past (Mormon 9).
  • Infants should not be baptized (Moroni 8:4-26).

Now contrast the above list of theological, cultural, and moral concerns with the types of issues that would have vexed any Israelite or Christian living in ancient Mesoamerica (where most Mormons think the Book of Mormon peoples lived): 

  • There are many gods, all associated with nature (maize, sun, earth, fire/lightning, rain, etc.).
  • The gods made man from maize after experiments produced monkeys and other creatures.
  • These gods were worshiped throughout ancient history using images or idols.
  • Ritual bloodletting, human sacrifice, and cannibalism were normal, widespread practices.
  • Quetzalcoatl was a feathered serpent deity associated with rain and fertility worshiped about a thousand years or more before the time of Christ.

This evidence shows beyond any reasonable doubt that the Book of Mormon is a nineteenth-century book.
