Curse and mark of Cain - http://en.wikipedia.org/wiki/Curse_and_mark_of_CainBigoted
Racial interpretationAccepting the theory that God had cursed black people, some have used the curse as a Biblical justification for racism. These racial and ethnic interpretations of the curse and the mark have been largely abandoned by theologians since the mid-20th century, although the theory still has some following, especially among white supremacists.
The split between the Northern and Southern Baptist organizations arose over slavery and the education of slaves. At the time of the split, the Southern Baptist group used the curse of Cain as a justification for the practice. In fact, most 19th and early 20th century Southern Baptist congregations in the southern United States taught that there were two separate heavens; one for blacks, and one for whites.<15>
The doctrine was used to support a ban on ordaining blacks to most Protestant clergies until the 1960s in both the U.S. and Europe. The majority of Christian Churches in the world, the ancient churches, including the Catholic Church, Eastern Orthodox churches, Anglican churches, and Oriental Orthodox churches, did not recognize these interpretations and did not participate in the religious movement to support them. Certain Catholic Diocese in the Southern United States did adopt a policy of not ordaining blacks to oversee, administer the Sacraments to, or accept confessions from white parishioners. This policy was not based on a Curse of Cain teaching, but was justified by any possible perceptions of having slaves rule over their masters. However, this was not approved of by the Pope or any papal teaching.<16>
Baptists and other denominations including Pentecostals officially taught or practiced various forms of racial segregation well into the mid-to-late-20th century, though members of all races were accepted at worship services after the 1970s and 1980s when many official policies were changed. In fact, it was not until 1995 that the Southern Baptist Convention officially renounced its "racist roots."<17>
Nearly all Protestant groups in America had supported the notion that black slavery, oppression, and African colonization was the result of God's curse on people with black skin or people of African descent through Cain
or through the curse of Ham, and some churches practiced racial segregation as late as the 1990s. Today, however, official acceptance and practice of the doctrine among Protestant organizations is limited almost exclusively to churches connected to white supremacy, such as the Aryan World Church and the New Christian Crusade Church.
Mormon
Mormons combined the widespread belief that Cain's curse was a blackness of skin with another idea common in Europe and America (that the curse of Ham for seeing his father's nakedness was black skin), the idea that Ham's wife preserved a curse of black skin inherited from Cain that was passed on is not canonized doctrine.<6> This interpretation is now generally rejected by mainstream Mormons.
