The following contradictions are not derived from Catholic teaching, Protestant criticism, or secular scholarship. They emerge from within Latter-day Saint scripture itself — placing the Book of Mormon, Doctrine & Covenants, and Pearl of Great Price in direct conflict with one another. Each pair of texts was canonized as the word of God by the same church.
This creates a logical problem independent of any external theological framework. If both scriptures are true, the contradiction must be resolved. If neither proposed resolution is textually defensible, then at least one of the revelations cannot be what it claims to be. A genuine prophetic tradition does not contradict itself in its own foundational documents.
The phrase "one God, without end" is a direct claim of divine unity — the same formulation as Nicene Trinitarian theology.
This passage teaches a form of divine unity that LDS scholars call "divine investiture" — but the plain text reads as modalistic (one God in two roles), not tritheistic (three Gods).
This verse establishes three entirely distinct, embodied (or spirit-bodied) persons — the direct opposite of the Book of Mormon's "one Eternal God" formulation. If the Father has a tangible body distinct from the Son, they cannot be "one God" in any natural reading of the phrase.
The First Vision establishes two visually separate, physically distinct beings — Father and Son — standing apart from each other. This is the experiential foundation for the tritheistic reading of D&C 130:22, directly contradicting the BoM's unity language.
The exaltation theology of D&C 132 presupposes a plurality of gods — humans may become gods — which requires the Father, Son, and Holy Ghost to be separate gods, not one unified divine being.

Mormon explicitly warns that imagining a changing God is to imagine a false god — making this a direct doctrinal rebuke of progressive theism.
This discourse, delivered by Joseph Smith less than three months before his death, is accepted by the LDS Church as authentic prophetic teaching, captured by multiple scribes and later published in the Times and Seasons.
This formulation, revealed to Lorenzo Snow and affirmed by Joseph Smith, has been repeatedly cited by LDS general authorities as binding doctrinal truth. It directly presupposes divine progression — God changed from mortal to divine — making His nature fundamentally mutable.
An embodied, material God is necessarily a God who came to have a body — implying a prior state, change of state, and therefore mutability. The Book of Mormon's "unchangeable from all eternity to all eternity" cannot be applied to such a being.

The command is categorical: one wife. The polygamy of David and Solomon is called "abominable." This is the word of the Lord as recorded in the Book of Mormon.
D&C 132 directly revisits David and Solomon — the same figures Jacob 2 condemned — and now describes their polygamy as something God justified. Jacob 2 called it abomination. D&C 132 calls it justification.
Here God explicitly exonerates David and Solomon's plural marriages as non-sinful (with a narrow exception). Jacob 2:24 called this "abominable before me, saith the Lord." The same Lord now says they did not sin in taking many wives.
D&C 132 legislates plural marriage in detail, setting its conditions for justified practice. Jacob 2 admits no such conditions: "there shall not any man among you have save it be one wife."

Alma ordains priests by his own authority — with no reference to Aaronic or Melchizedek orders, no lineage requirement, and no angelic conferral. The structure is entirely different from D&C's schema.
"After the order of his Son" is retroactively identified by LDS theology as Melchizedek Priesthood. But Alma 13 does not use the term "Melchizedek" in any functional church-organizational sense, nor does it describe a dual-tier priesthood system.
The resurrected Christ reorganizes the Nephite church — yet still no mention of conferring Aaronic or Melchizedek Priesthood by the titles, roles, or structure elaborated across dozens of D&C sections.
John the Baptist physically appears to confer a distinct, named priesthood order. This two-tiered system is the formal organizational skeleton of the entire LDS Church — yet it appears nowhere in the millennium of Nephite history recorded in the Book of Mormon.
D&C 107 elaborates a comprehensive two-tiered system with distinct offices (deacon, teacher, priest under Aaronic; elder, seventy, high priest under Melchizedek), keys, and authorities. None of this organizational detail appears in the Book of Mormon's account of Christ's church among the Nephites.
D&C 84 ties Aaronic Priesthood explicitly to the Levitical lineage of Aaron and the house of Israel. Nephites in the Book of Mormon were not Levites — they descended from Joseph through Manasseh — raising further questions about how they exercised functions D&C assigns exclusively to the Aaronic order.

Even with its "after all we can do" qualifier, this verse presents salvation as the fruit of grace — not exaltation contingent on temple sealings, eternal marriage covenants, or posthumous ordinance work. No temple ceremony appears in the Book of Mormon's path to salvation.
The universal resurrection restores all mankind to God's presence — a broadly inclusive soteriology with no mention of temple ordinances as necessary for this restoration.
The highest degree of celestial glory — full exaltation and divine status — requires temple marriage. This is an ordinance the Book of Mormon never mentions in any soteriological context. The BoM's Mosiah 3:17 says salvation comes only through Christ's name; D&C 131 adds a required ordinance as the gating condition for full exaltation.
The three-kingdom schema of D&C 76 is entirely absent from the Book of Mormon, which presents a binary (eternal life with God vs. spiritual death) rather than the graduated, merit-differentiated afterlife of D&C theology.
Proxy temple work for the dead is presented as essential to salvation — a soteriological category that appears nowhere in the Book of Mormon. The BoM's universal atonement in Helaman 14 does not condition anyone's salvation on living relatives performing posthumous ordinances.

✦ The Significance of Internal Contradictions ✦
These contradictions are categorically different from disagreements between LDS scripture and external sources. They arise within the canon the LDS Church itself declares to be the word of God. A Catholic or Protestant critic can be dismissed as arguing from a competing tradition. But when the Book of Mormon and Doctrine & Covenants issue opposite divine verdicts on the same question — when God calls polygamy an abomination and a justified commandment, when the Father is one unchangeable eternal God and a progressed embodied being — no appeal to tradition resolves the tension.
The Catholic theological tradition does not face this problem. The Church's doctrinal development across two millennia operates by explicating what was always implicitly contained in the deposit of faith — never by issuing contradictory divine commands on the same subject to the same community. The internal incoherence of the LDS Standard Works is not a peripheral apologetic observation. It is a structural problem at the foundation of the LDS truth claim.
