When the Angel Moroni appeared to Joseph Smith on the night of September 21, 1823, he imparted to the youthful Seer many truths of the greatest importance pertaining to the restoration of the Gospel and the establishment of the Church which, the angel said, was about to take place. These instructions were of such weight that they were repeated twice more that night and again the following day, in order that this young man, upon whose shoulders the burden of the latter day work should rest, might be sufficiently impressed with the greatness and importance of his mission. Among the instructions given by the angel at this time, the doctrine of salvation for the dead had an important part. This heavenly messenger said that the prophecy of Malachi the Prophet was about to be fulfilled, and he quoted the fourth chapter of Malachi, but with this variation:
"For, behold, the day cometh that shall burn as an oven, and all the proud, yea, and all that do wickedly shall burn as stubble; for they that come shall burn them, saith the Lord of hosts, that it shall leave them neither root nor branch. * * * Behold, I will reveal unto you the Priesthood, by the hand of Elijah the prophet, before the coming of that great and dreadful day of the Lord. And he shall plant in the hearts of the children the promises made to their fathers, and the hearts of the children shall turn to their fathers; if it were not so, the whole earth would be utterly wasted at his coming." (History of the Church, Vol. I, page 12.)
At that time the full meaning and glory and significance of this instruction were not understood by the Prophet, although it made a deep impression on his mind. On the 3d day of April, 1836, it was fulfilled, for Elijah the Prophet appeared in the Kirtland Temple to Joseph Smith and Oliver Cowdery, and conferred upon them this Priesthood and the keys of the salvation for the dead stating that—
"Behold the time has fully come, which was spoken of by the mouth of Malachi, testifying that he (Elijah) should be sent before the great and dreadful day of the Lord come. To turn the hearts of the fathers to the children, and the children to their fathers, lest the whole earth be smitten with a curse. Therefore the keys of this dispensation are committed into your hands, and by this ye may know that the great and dreadful day of the Lord is near, even at the doors." (Doc. and Cov. 110: 13-16. History of "Reorganized" Church, Vol. 2, page 47.)
Following the bestowal of this Priesthood with its keys, the spirit of salvation for the dead was poured out in abundance upon the heads of the Prophet and his people whose hearts began to turn toward their dead fathers. After the Church settled in Nauvoo, baptism for the dead was instituted, the Lord, at first, permitting the ordinance to be performed in the Mississippi river, but later revealing to the Saints that the proper place for this and other rites for the salvation of the dead, must be performed in a Temple built purposely for such ordinances, and that only in times of their extreme poverty could these ordinances be performed elsewhere by His people. Such a temple the Saints were commanded to build, and on the 21st of November, 1841, baptisms for the dead, which had been discontinued in the river at Nauvoo by command of God, October 3, 1841, were resumed in the font of the Lord's House, which had been dedicated for that purpose.[[2]] These ordinances continued to be performed until the Temple was completed and the Saints were driven from Nauvoo. The spirit of Elijah's work, which had rested so mightily upon the Prophet Joseph, continued with Brigham Young and the "Mormon" people during their travels in the wilderness, and when they arrived in the valleys of the Rocky Mountains, the first commandment to them from the Lord, was to build a Temple to His name, where the ordinances of salvation for the living and for the dead could be performed. This work was done as speedily as possible and from that day to the present the spirit of Temple building and of Temple work for the salvation of mankind has continued with the Church.
This action on the part of the Church under the leadership of the successors of Joseph Smith is in harmony with the Scriptures and the teachings and commandments given to the Prophet. He declared that baptism for the dead—the opening of the prison house to them that sit in darkness, and the proclamation of liberty to the captives—was the most glorious of all subjects belonging to the everlasting Gospel, and so greatly was he wrought upon by this work that the subject occupied his mind almost constantly before his death. Moreover, a short time before his martyrdom, the Prophet bestowed upon the Twelve Apostles—who constitute the second quorum in the Church—all the keys and all the ordinances and Priesthood necessary for them to hold in order to carry on this great and glorious work of universal salvation.
That the Twelve did receive these keys and powers, we learn from the following quotations from the Times and Seasons. Orson Hyde, one of that quorum, said:
"Before I went east on the 4th of April (1844) last, we were in council with Brother Joseph almost every day for weeks, said Brother Joseph in one of those councils, there is something going to happen; I don't know what it is, but the Lord bids me to hasten and give you your endowment before the Temple is finished. He conducted us through every ordinance of the Holy Priesthood, and when he had gone through with all the ordinances he rejoiced very much, and said, now if they kill me you have got all the keys, and all the ordinances and you can confer them upon others, and the hosts of Satan will not be able to tear down the Kingdom as fast as you will be able to build it up; and now, said he, on your shoulders will the responsibility of leading this people rest." (Times and Seasons, Vol. 5, page 651.)
This testimony is corroborated by the testimony of Elder Wilford Woodruff, which is found in the same volume, page 698, wherein he says:
"And when they (the Twelve) received their endowment, and actually the keys of the Kingdom of God, and oracles of God, keys of revelation, and the pattern of heavenly things; and thus addressing the Twelve (Joseph) exclaimed, 'Upon your shoulders the Kingdom rests, and you must round up your shoulders and bear it, for I have had to do it until now.'"
