"The Prophet Joseph Smith said, 'The greatest responsibility in this world that God has laid upon us is to seek after our dead' (History of the Church, 6:313). From the beginning, Relief Society sisters have supported this great work. In Nauvoo in 1842, Sarah M. Kimball's desire to help the temple construction workers prompted a group of sisters to organize themselves so that they could serve more effectively. As they began to meet, the Prophet … organized the first Relief Society after the pattern of the priesthood. From that time on, the Relief Society sisters helped further the work on the Nauvoo Temple. …
"In 1855, eight years after the Saints first arrived in Utah, the Endowment House was established. Eliza R. Snow, who had been one of the original members of the first Relief Society and had preserved the records of that organization, was called by President Brigham Young in 1866 to be the general Relief Society president. She and other sisters were faithful workers in the Endowment House. Then, as the St. George, Logan, and Manti Temples were completed, these sisters traveled to each temple so they could do work for the dead there."1
