At the October 1890 general conference, President Wilford Woodruff called on his counselor George Q. Cannon to speak just after an official declaration on plural marriage was read. Knowing what people had sacrificed for plural marriage, President Cannon was nervous about how to explain the move away from the practice. “I felt to shrink very much from it,” he later wrote. “I think I never was called upon to do a thing that seemed more difficult than this.” Only after he rose to face the congregation did inspiration come to him about how to help the Saints accept the change.
