After this doctrine was revealed the Lord granted the Saints the privilege of performing the ordinance of baptism for the dead in the Mississippi River, until such time as a font could be prepared in the basement of the temple. When a temporary font was prepared, and long before the temple was completed, this privilege of baptizing for the dead in any other place than the temple was discontinued by commandment of the Lord. So important was this work in behalf of the salvation of the worthy dead, that the Lord declared that the living could not be made perfect without them, and, when the opportunity presented itself, should the members of the Church fail to perform the ordinance for their dead, the Lord said he would reject them, for the dead were to be saved by the same principles which would save the living. Things Hid from the Foundation of the World Not only was the ordinance of baptism for the dead to be performed in the temple, but the Lord promised to reveal many things "which have been kept hid from before the foundation of the world, things that pertain to the Dispensation of the Fulness of Times." Here the keys of the Holy Priesthood were to be received, for such were ordained to be obtained in temples that the Saints may receive honor and glory, both the living and, by proxy, the dead, even those blessings by which they should be crowned with honor, immortality and eternal life. The Nauvoo House Another house was also to be built in Nauvoo. This was the Nauvoo House, a place for the boarding of strangers. Joseph Smith, Sidney Rigdon, Hyrum Smith, and many others were called upon to "pay stock" for themselves and their seed after them "from generation to generation," in this house. It was to be a place where the "weary traveler may find health and safety while he shall contemplate the word of the Lord; and the corner stone [stake] I have appointed for Zion," said the Lord. Those who took stock were not to pay less than fifty dollars, and not more than fifteen thousand dollars for any one man. The Calling of Hyrum Smith Another important commandment in this revelation was the appointment of Hyrum Smith, to act as patriarch in the office which had been held by his father, and also his ordination to be a "prophet, seer and revelator" unto the Church, as well as Joseph Smith. The Lord had pointed out several years before, when Joseph Smith, Sen., was called to be the patriarch of the Church, that this office was his by right of lineage, and descended from father to son, and was the right based on faithfulness of the first born. At the time of Hyrum Smith's call, he was serving as second counselor in the First Presidency, a place he was called to occupy after the transgression of Frederick G. Williams. The revelation relating to this appointment reads as follows:
