And if any man mingle his seed with the seed of Cain the only way he could get rid of it or have Salvation would be to come forward and have his head cut off and spill his blood upon the ground -- it would also take the life of his children.
Wilford Woodruff. Wilford Woodruff's personal diary, 4:97.
Man will be punished for his own sins and not for Adam's transgression. If this is carried further, it would imply that the Negro is punished or allotted to a certain position on this earth, not because of Cain's transgression, but came to earth through the loins of Cain because of his failure to achieve other stature in the spirit world.
George Albert Smith. Official Statement of First Presidency issued on August 17, 1951.
