NOTE: The Book of Abraham was produced by Joseph Smith between 1835 and 1842. He claimed that he had translated it from an ancient papyrus containing the writings of Abraham, written in his own hand. The following excerpts contain two key doctrinal elements on which was based traditional Mormon teaching about race and the priesthood. The first was that the bloodline of Ham was cursed so as to be disqualified from holding the priesthood. The second was the doctrine that human beings lived as spirits in heaven before becoming mortals on earth. In this “preexistence” some spirits were more noble or great than others. For most of its history, the LDS Church interpreted this teaching to explain why some people were born with black skin: they had been the less noble spirits in the preexistence.

21 Now this king of Egypt was a descendant from the loins of Ham, and was a partaker of the blood of the Canaanites by birth. 22 From this descent sprang all the Egyptians, and thus the blood of the Canaanites was preserved in the land. 23 The land of Egypt being first discovered by a woman, who was the daughter of Ham, and the daughter of Egyptus, which in the Chaldean signifies Egypt, which signifies that which is forbidden; 24 When this woman discovered the land it was under water, who afterward settled her sons in it; and thus, from Ham, sprang that race which preserved the curse in the land. 25 Now the first government of Egypt was established by Pharaoh, the eldest son of Egyptus, the daughter of Ham, and it was after the manner of the government of Ham, which was patriarchal. 26 Pharaoh, being a righteous man, established his kingdom and judged his people wisely and justly all his days, seeking earnestly to imitate that order established by the fathers in the first generations, in the days of the first patriarchal reign, even in the reign of Adam, and also of Noah, his father, who blessed him with the blessings of the earth, and with the blessings of wisdom, but cursed him as pertaining to the Priesthood. 27 Now, Pharaoh being of that lineage by which he could not have the right of Priesthood, notwithstanding the Pharaohs would fain claim it from Noah, through Ham, therefore my father was led away by their idolatry; 28 But I shall endeavor, hereafter, to delineate the chronology running back from myself to the beginning of the creation, for the records have come into my hands, which I hold unto this present time. (Abr. 1:21-28)

22 Now the Lord had shown unto me, Abraham, the intelligences that were organized before the world was; and among all these there were many of the noble and great ones; 23 And God saw these souls that they were good, and he stood in the midst of them, and he said: These I will make my rulers; for he stood among those that were spirits, and he saw that they were good; and he said unto me: Abraham, thou art one of them; thou wast chosen before thou wast born. 24 And there stood one among them that was like unto God, and he said unto those who were with him: We will go down, for there is space there, and we will take of these materials, and we will make an earth whereon these may dwell; 25 And we will prove them herewith, to see if they will do all things whatsoever the Lord their God shall command them; 26 And they who keep their first estate shall be added upon; and they who keep not their first estate shall not have glory in the same kingdom with those who keep their first estate; and they who keep their second estate shall have glory added upon their heads for ever and ever. (Abr. 3:22-26)
