Section 18: The Pre-Mortal Existence — Spirit-Children of God

LDS theology teaches that all human beings existed as spirit-children in a pre-mortal realm before their birth on earth. In this pre-mortal existence, they were children of Heavenly Father and a Heavenly Mother (a significant doctrine that remains relatively underdeveloped in official LDS teaching but is widely believed). They chose to follow Heavenly Father's plan, which included mortality, the possibility of exaltation, and Jesus Christ as their savior. Lucifer proposed an alternative plan — compelled obedience rather than freedom with accountability — and was cast out with those who followed him.

This doctrine provides the LDS framework for the problem of evil (those who suffer chose difficult earthly circumstances pre-mortally), racial inequality (historically linked to pre-mortal choices), and the purpose of mortality (a necessary step in the progression toward exaltation).

ERROR IDENTIFIED: The Bible does not teach a pre-mortal existence of human souls. Hebrews 9:27 states that "people are destined to die once, and after that to face judgment" — a single death following a single mortal life, not a pre-mortal existence, mortality, and then judgment. Jeremiah 1:5 ("Before I formed you in the womb I knew you") is sometimes cited in LDS contexts but refers to God's foreknowledge, not a pre-mortal personal existence. Psalm 139:13–16 describes God forming the individual in the womb — not a pre-mortal spirit entering a body. The pre-mortal existence doctrine is a philosophical addition to the biblical text, derived from the Book of Abraham and subsequent LDS revelation, not from Scripture.

Section 19: The Plan of Salvation — A System of Progressive Exaltation

LDS theology organizes human existence around a "plan of salvation" (also called the plan of happiness). Pre-mortal spirits come to earth and receive physical bodies. They are tested in mortality. Those who accept the full gospel — baptism, confirmation, priesthood (for men), temple endowment, and celestial marriage — are on the path to exaltation. After death, spirits enter the spirit world, where missionary work continues and proxy ordinances on earth can provide those who died without the gospel an opportunity to receive it. The final judgment assigns each person to one of three degrees of glory, or, for the most wicked, outer darkness.

The plan is comprehensive, systematic, and emotionally resonant. It accounts for the fate of those who never heard the gospel. It gives a purpose to family relationships that extends beyond death. It provides a cosmic narrative in which every person has a role. It is one of the most elaborately developed soteriological systems in the history of American religion.

ERROR IDENTIFIED: The plan of salvation is doctrinally coherent on its own terms. Its problem is not internal inconsistency but external collision — collision with the New Testament at every significant point. The three degrees of glory are derived from a single vision (D&C 76), not from the apostolic teaching. The proxy ordinance system rests on the doctrinal premise that baptism is necessary for salvation — a premise that Ephesians 2:8–9 ("it is by grace you have been saved, through faith") explicitly undermines. The missionary work in the spirit world rests on the premise that the church's ordinances are necessary — which rests on the Great Apostasy, which requires Matthew 16:18 to be false. The plan is internally coherent and externally incompatible with the New Testament at its foundation.
