This declaration from the Lord would indicate that the purpose for which the Kirtland Temple was erected was now fulfilled, and its mission completed; and this was indeed the case. The Kirtland Temple served temporarily only. It was built because a house was necessary where the Lord could come and restore the various keys of former dispensations, that the Dispensation of the Fulness of Times might be made complete. In the Kirtland Temple the Lord gave a partial endowment, but not in the fulness, that the apostles and others might be endowed with necessary power to go forth “to prune the vineyard for the last time.” But the great object was the restoration of the keys of former dispensations. When these were bestowed, then greater light was revealed, and the full purpose of temples and ordinance work therein was made known. It then became necessary that a house of the Lord should be built that would be perfect in all its parts, which was not the case in the structure of the Kirtland Temple. That edifice, although one of the most important ever erected by the Church, was not a complete structure as temples are understood through increased revelation. In it there were no provisions for the salvation of the dead; it had not a baptismal font—a fundamental part of the perfect temple—and therefore, since it had filled the measure of its creation, the Lord declared in the revelation of January, 1841, that there was not a house on the earth where he could come to bestow the fulness of the Priesthood and introduce the essential ordinances for the salvation of both the living and the dead. Moroni, John the Baptist, Peter, James and John, all came before there was a temple; but their coming was necessary that the foundation might be laid and the Church established. The Lord has made provision that in the sacred grove, the forest, and on the mountain top, such keys may be bestowed, when there is no temple erected to his name, and in the poverty of the people. Otherwise such keys are to be received only in the temple reared to his holy name.
Baptism for the Dead
The doctrine of baptism for the dead was first made known to the Saints in a discourse by the Prophet at the funeral of Elder Seymour Brunson, August 10, 1840. This doctrine was not understood by him until after the restoration of the keys and the Priesthood of Elijah in the Kirtland Temple, although it had been referred to since the night of the first appearance of Moroni. In this revelation of January, 1841, the Lord revealed greater light regarding this wonderful principle. It was here made known that this ordinance was to be performed in the temple of the Lord. A baptismal font for this purpose was to be placed in the basement of the temple, “as a simile of the grave,” and was commanded to be in a place underneath where the living are wont to assemble, to show forth the living and the dead; and that all things may have their likeness, and that they may accord one with another; that which is earthly conforming to that which is heavenly” (Doc. and Cov. Sec. 128:13).
In an epistle to the Twelve Apostles, who were at the time in Europe, President Joseph Smith, October 19, 1840, made the following statement:
“I presume the doctrine of ‘baptism for the dead’ has ere this reached your ears, and may have raised some inquiries in your minds respecting the same. I cannot in this letter give you all the information you may desire on the subject; but aside from knowledge independent of the Bible, I would say that it was certainly practiced by the ancient churches; and St. Paul endeavors to prove the doctrine of the resurrection from the same, and says, ‘Else what shall they do which are baptized for the dead, if the dead rise not at all? Why are they then baptized for the dead?’
“I first mentioned the doctrine in public when preaching the funeral sermon of Brother Seymour Brunson; and have since then given general instructions in the Church on the subject. The Saints have the privilege of being baptized for those of their relatives who are dead, whom they believe would have embraced the Gospel, if they had been privileged with hearing it, and who have received the Gospel in the spirit, through the instrumentality of those who have been commissioned to preach to them while in prison.”
The Rite Performed in the River
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.
