“The hearts of the children of men will have to be turned to their fathers, and the fathers to the children, living or dead, to prepare them for the coming of the Son of Man. If Elijah did not come, the whole earth would be smitten.”Joseph Smith, June 2, 1839 · The Priesthood—The Second Advent—The Gathering—Spiritual Ministrations and Manifestations · JD 6:237-240
