Wow. I don’t know how I would have approached the topic of what other religions believe from a purely unemotional standpoint. What did you do?

Today, it would seem that the members of the Church of Jesus Christ of Latter-day Saints, also known as “Mormons”, subscribe to a form of the heresy of adoptionism. (Adoptionism is the belief that Jesus became divine at some point in time.) It is very difficult to find any absolute statements of doctrine for the LDS ecclesial community. They have no creed or catechism, and a later LDS “prophet” can change what earlier an earlier LDS “prophet” or “prophets” taught. The Encyclopedia of Mormonism was printed in 1992, but its editor writes:
Those who have written and edited [the Encyclopedia of Mormonism] have only tried to explain their understanding of Church history, doctrines, and procedures; their statements and opinions remain their own. The Encyclopedia of Mormonism is a joint product of Brigham Young University and Macmillan Publishing Company, and its contents do not necessarily represent the official position of The Church of Jesus Christ of Latter-day Saints (Ludlow).
That being said, it seems to be the consensus that Jesus is the firstborn “spirit child” of God the Father, and all human beings also lived in heaven as spirit children of God the Father before their births here on earth since at least two contributors to the Encyclopedia of Mormonism say:
In the premortal life, Jesus Christ, whose main title was Jehovah, was the firstborn spirit child of God the Father and thus the eldest brother and preeminent above all other spirit children of God (Millet).
and
Fundamental to the teachings of The Church of Jesus Christ of Latter-day Saints is the concept that all human beings were born as spirit sons and daughters of heavenly parents before any were born as mortals to earthly parents. Latter-day Saints believe that the eldest and firstborn spirit child of God is Jehovah and that it was he who was later born with a physical body to mary [sic] as Jesus Christ. That is, Jehovah of the Old Testament became Jesus Christ of the New Testament when he was born into mortality. The Psalmist refers to the Messiah as the firstborn (Ps. 89:27), and the apostle Paul speaks of Jesus as the “firstborn among many brethren” (Rom. 8:29; cf. Heb. 2:17) and as the “firstborn of every creature” (Col. 1:15). Perhaps the most authoritative statement on the subject is from the Savior himself, who declared to the Prophet Joseph Smith, “I was in the beginning with the Father, and am the Firstborn” (D&C 93:21). In 1909 the First Presidency of the Church declared: The Father of Jesus is our Father also. Jesus Himself taught this truth, when He instructed His disciples how to pray: “Our Father which art in heaven,” etc. Jesus, however, is the firstborn among all the sons of God—the first begotten in the spirit, and the only begotten in the flesh. He is our elder brother, and we, like Him, are in the image of God. All men and women are in the similitude of the universal Father and Mother, and are literally the sons and daughters of Deity [MFP 4:203] [Citations in the original] (Giles).
So, according to Mormon belief, all human beings, including Jesus, began their lives as “spirit children” in heaven. Jesus Christ is the eldest and firstborn spirit child of God. So, what is it that makes him different from other human beings? How did he become divine? Unlike the rest of the members of the human race who have two human parents, God the Father is literally Jesus’ earthly father as well as being his heavenly father:
Ancient and modern scriptures use the title Only Begotten to emphasize the divine nature of Jesus Christ. Latter-day Saints recognize Jesus as literally the Only Begotten Son of God the Father in the flesh (John 3:16; D&C 93:11; Moses 6:52). This title signifies that Jesus’ physical body was the offspring of a mortal mother and of the eternal Father (Luke 1:35, 1Ne. 11:18). It is LDS doctrine that Jesus Christ is the child of mary [sic] and God the Father, “not in violation of natural law but in accordance with a higher manifestation thereof” (JC, p. 81).
The fact of Jesus’ being the literal Son of God in the flesh is crucial to the Atonement, which could not have been accomplished by an ordinary man. Because of the Fall of Adam, all mankind are subject to physical death and are shut out from the presence of God. The human family is unable to save itself. Divine law required the sacrifice of a sinless, infinite, and eternal being—a God (This is huge…an eternal being would be a being who had no beginning and no end, yet the Mormon belief is that Jesus had a beginning as a “spirit child”) —someone not dominated by the Fall, to redeem mankind from their lost and fallen condition (Alma 34:9-14; cf. 42:15). This price of redemption was more than any mortal person could pay, and included the spiritual sufferings and physical agony in Gethsemane (Luke 22:44; Mosiah 3:7; D&C 19:18). To complete the Atonement by physical death and resurrection, it was necessary that Jesus be able to lay down his physical body and also be able to take it up again. He could do this only because he had life in himself, which he inherited from God his Father (John 5:26;10:17-18). Christ inherited the ability to die from his mortal mother and the power to resurrect himself from his immortal Father. Dying was for him a voluntary, deliberate act for mankind, made possible only because he was the Only Begotten of the Father (D&C 20:18-26) [Citations in the original] (Hansen).
So, according to Mormon belief, it would seem Jesus became divine only at his conception in a physical body.
