Journal of Discourses 2:44 “Who revealed to him [Joseph Smith] the plan of redemption, and of exaltation for the dead who had died without the Gospel? and the keys and preparations necessary for holy and perpetual converse with Jesus Christ, and with the spirits of just men made perfect, and with the general assembly and Church of the first-born, in the holy of holies? Those from the dead!” – Parley Parker Pratt, Great Salt Lake City, April 6, 1853
