In his office, religion professor Randy Bott explains a possible theological underpinning of the ban. According to Mormon scriptures, the descendants of Cain, who killed his brother, Abel, “were black.” One of Cain’s descendants was Egyptus, a woman Mormons believe was the namesake of Egypt. She married Ham, whose descendants were themselves cursed and, in the view of many Mormons, barred from the priesthood by his father, Noah. Bott points to the Mormon holy text the Book of Abraham as suggesting that all of the descendants of Ham and Egyptus were thus black and barred from the priesthood.

“God has always been discriminatory” when it comes to whom he grants the authority of the priesthood, says Bott, the BYU theologian. He quotes Mormon scripture that states that the Lord gives to people “all that he seeth fit.” Bott compares blacks with a young child prematurely asking for the keys to her father’s car, and explains that similarly until 1978, the Lord determined that blacks were not yet ready for the priesthood.

“What is discrimination?” Bott asks. “I think that is keeping something from somebody that would be a benefit for them, right? But what if it wouldn’t have been a benefit to them?” Bott says that the denial of the priesthood to blacks on Earth — although not in the afterlife — protected them from the lowest rungs of hell reserved for people who abuse their priesthood powers. “You couldn’t fall off the top of the ladder, because you weren’t on the top of the ladder. So, in reality the blacks not having the priesthood was the greatest blessing God could give them.”
