Brigham Young Taught Blood Atonement

"There is not a man or woman who violates the covenants made with their God (in the Mormon temples), that will not be required to pay the debt. The blood of Christ will never wipe that out, your own blood must atone for it; and the judgments of the Almighty will come, sooner or later, and every man or woman will have to atone for breaking their covenants." - From sermon by Brigham Young, March 16, 1856, Journal of Discourses, Vol. III., page 247.
