Resumo: There exist previously taught ideas which have been repudiated by Church leaders since the ban. Among these are the notion that Blacks were somehow not as "valiant" in the pre-existence, and that interracial marriage is forbidden.
: It is true that LDS scripture states that those with lighter skin color "are favored because of what they did as spirits in a pre-earth life?" Is it true that some Church leaders taught that people who were born with dark skin were "neutral" in the pre-existence?
: We often hear that Latter-day Saints believe and teach that blacks are descendents of Cain, and that they are cursed. In fact, on some occasions prior to 1978, blacks were denied access to temple open houses because they carried the “mark of Cain.” What critics never point out, however, is that the "curse of Cain" is a Protestant invention that was created in order to justify slavery in the 1800's. One would get the impression listening to critics that the Latter-day Saints originated the idea of the curse, and they point to the priesthood ban as evidence of such, while ignoring that fact of segregated congregations in Protestant churches of that era.
: Is it true that the LDS scriptures link a person's skin color to their behavior in the pre-existence, and that the Book of Mormon is racist and promotes the idea that the "white" race is superior? Some contend that even though the doctrinal impact of pre-1978 statements have been greatly diminished, the LDS scriptures still retain the passages which were used for proof-texts for the ban and hence cannot be easily dismissed. A parallel can be drawn between Protestant denominations that have historically reversed their scriptural interpretations supporting slavery and a modified LDS understanding of their own scriptures that relate to the priesthood ban. Through more careful scripture reading and attention to scientific studies, many Protestants have come to differ with previous interpretations of Bible passages. A similar rethinking of passages unique to the LDS scriptures, such as Abraham 1:26-27, can be made if one starts by discarding erroneous preconceptions.
