Who is Cain?
Mormon Doctrine, pg 108; “Though he was a rebel and an associate of Lucifer in pre-existence, and though he was a liar from the beginning whose name was Perdition, Cain managed to attain the privilege of mortal birth… he came out in open rebellion, fought God, worshipped Lucifer, and slew Abel…As a result of his rebellion, Cain was cursed with a dark skin; he became the father of the Negroes, and those spirits who were not worthy to receive the priesthood are born through his lineage.”
