-Interacial marriage is punishable by death for salvation
“Shall I tell you the law of God in regard to the African Race? If the White man who belongs to the chosen seed mixes his blood with the seed of Cain, the penalty, under the law of God, is death on the spot. This will always be so.” President Brigham Young, Journal of Discourses, Vol. 7, pg. 290-291
-People of African descent are the seed of Satan
“And after the flood we are told that the curse that had been pronounced upon Cain was continued through Hams' wife, as he had married a wife of that seed. And why did it pass through the flood? Because it was necessary that the devil should have a representative upon the earth as well as God.” President John Taylor, Journal of Discourses, Vol. 22, pg. 304.
-Dark Skin is God's Curse
2 NEPHI 5:21
“And he had caused the cursing to come upon them, yea, even a sore cursing, because of their iniquity. For behold, they had hardened their hearts against him, that they had become like unto a flint; wherefore, as they were white, and exceedingly fair and delightsome, that they might not be enticing unto my people the Lord God did cause a skin of blackness to come upon them.
And thus saith the Lord God: I will cause that they shall be loathsome unto thy people, save they shall repent of their iniquities.
And cursed shall be the seed of him that mixeth with their seed; for they shall be cursed even with the same cursing. And the Lord spake it, and it was done.
And because of their cursing which was upon them they did become an idle people, full of mischief and subtlety, and did seek in the wilderness for beasts of prey.”
-Racism has it's root in the origin and doctrines of the Mormon Faith
"In a broad general sense, caste systems have their root and origin in the gospel itself, and when they operate according to the divine decree, the resultant restrictions and segregation are right and proper and have the approval of the Lord. To illustrate: Cain, Ham, and the whole Negro race have been cursed with a black skin, the mark of Cain, so they can be identified as a caste apart, a people with whom the other descendants of Adam should not intermarry. (Gen. 4; Moses 5.) The whole house of Israel was chosen as a peculiar people, one set apart from all other nations (Ex. 19:5-6; Deut. 7:6; 14:2); and they were forbidden to marry outside their own caste. (Ex. 34:10-17; Deut. 7:1-5.) In effect the Lamanites belonged to one caste and the Nephites to another, and a mark was put upon the Lamanites to keep the Nephites from intermixing with and marrying them. (Alma 3:6-11.) All this is not to say that any race, creed, or caste should be denied any inalienable rights. But it is to say that Deity in his infinite wisdom, to carry out his inscrutable purposes, has a caste system of his own, a system of segregation of races and peoples. The justice of such a system is evident when life is considered in its true eternal perspective. It is only by a knowledge of pre-existence that it can be known why some persons are born in one race or caste and some in another. " Apostle Bruce R. McConkie, Mormon Doctrine, p. 114
-African Americans cannot hold the Priesthood
“Tough he was rebel and an associate of Lucifer in pre-existence, and though he was a liar from the beginning whose name was Perdition, Cain was cursed with a dark skin; he became the father of the Negroes, and those sprits who are not worthy to receive the priesthood are born though his lineage. He became the first mortal to be cursed as a son of perdition. As a result of his mortal birth he is assured of a tangible body of flesh and bones in eternity, a fact which will enable him to rule over Satan.” Apostle Bruce R. McConkie, Mormon Doctrine, pp. 102.
-"Negroes are not equal with other races"
Through Ham (a name meaning black) the blood of the Canaanites was preserved through the flood, he having married Egyptus, a descendent of Cain.
Negroes in this life are denied the priesthood; under no circumstances can they hold this delegation of authority from the Almighty. The gospel message of salvation is not carried affirmatively to them... Negroes are not equal with other races where the receipt of certain spiritual blessings are concerned....” Apostle Bruce R. McConkie, Mormon Doctrine, pg. 343 This is a modern apostle of the LDS Church.
-Your skin color will change when you become a Mormon
“I saw a striking contrast in the progress of the Indian people today.... The day of the Lamanites is nigh. For years they have been growing delightsome, and they are now becoming white and delightsome, as they were promised. In this picture of the twenty Lamanite missionaries, fifteen of the twenty were as light as Anglos, five were darker but equally delightsome The children in the home placement program in Utah are often lighter than their brothers and sisters in the hogans on the reservation.
“There were no neutrals in the war in heaven. All took sides either with Christ or with Satan. Every man had his agency there, and men receive rewards here based upon their actions there, just as they will receive rewards hereafter for deeds done in the body. The Negro, evidently, is receiving the reward he merits.” President Joseph Fielding Smith, Doctrines of Salvation,pp. 65-66.
