Heber C. Kimball requests beheading if he ever seduces a woman.
Heber C. Kimball, "Sanctification," Journal of Discourses, 26 vols. (Liverpool: 1862), 7:20
These are my views, and the Lord knows that I believe in the principles of sanctification; and when I am guilty of seducing any man's wife, or any woman in God's world, I say, sever my head from my body. These have ever been my feelings from the days of my youth. This is my character, and the character of President Brigham Young. It was the character of Joseph Smith and of Jesus Christ; and that is the character of the Apostles of Jesus, and that must be sustained by this people.
