“The moment we consent to mingle with the seed of Cain [claimed by Mormons to be the African Race] the Church must go to destruction, – we should receive the curse which has been placed upon the seed of Cain, and never more be numbered with the children of Adam who are heirs to the preisthood untill that curse be removed.”
