Brigham Young spoke for many Saints in 1863 when he assessed the Civil War raging in the East: 'One portion of the country wish [sic] to raise their ... black slaves and the other wish [sic] to free them, and apparently to almost worship them.... Who cares? ... Ham will continue to be the servant of servants, as the Lord has decreed, until the curse is removed.'
Cain, in murdering Abel, had 'deprived his brother of the privilege of pursuing his journey through life, and of extending his kingdom by multiplying upon the earth.' Cain had reportedly hoped thereby to gain an advantage over Abel—the number of one's posterity somehow being important in the overall scheme of things. Brigham Young further explained that those who were to have been Abel's descendants had already been assigned to his lineage, and if they were ever to come "into the world in the regular way, they would have to come through him." In order that Cain's posterity not gain an advantage the Lord denied them the priesthood until such time as "the class of spirits presided over by Abel should have the privilege of coming into the world." Those spirits formerly under Cain's leadership were reportedly aware of the implications of this decision, yet "still looked up to him, and rather than forsake him they were willing to bear his burdens and share the penalty imposed upon him."
