Wilford Woodruff records Brigham explaining a restriction on priesthood and temple blessings for any man having "one drop of the seed of Cane in him."
Wilford Woodruff, Journal, January 16, 1852, MS 1352, Church History Library
Any man having one drop of the seed of Cane in him cannot hold the priesthoo[d] & if no other prophet ever spake it Before I will say it now in the name of Jesus Christ I know it is true & others know it the Negro cannot hold one part[icle] of Government But the day will come when all the seed of Cane will be Redeemed & have all the Blessings we have now & a great deal more But the seed of Abel will be ahead of the seed of Cane to all Etarnity.
