Doctrine & Covenants section 138 sheds the most light on our temple work. How could President Joseph F. Smith have seen his brother Alvin in the Celestial glory (D&C 138:5 “5 I saw Father Adam and Abraham; and my father and my mother; my brother Alvin, that has long since slept;”) even though he had was born on
February 11, 1798 but had died on November 19, 1823, almost seven years before the church was organized (April 6, 1830), and the practice of being baptized for the deceased wasn’t practiced (in this dispensation—see 1 Corinthians 15:29 “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?”) until 1840.
In Doctrine & Covenants section 127, it reads, starting inverse 4:
“6 Verily, thus saith the Lord unto you concerning your dead: When any of you are baptized for your dead, let there be a recorder, and let him be eye-witness of your baptisms; let him hear with his ears, that he may testify of a truth, saith the Lord;
7 That in all your recordings it may be recorded in heaven; whatsoever you bind on earth, may be bound in heaven; whatsoever you loose on earth, may be loosed in heaven;
8 For I am about to restore many things to the earth, pertaining to the priesthood, saith the Lord of Hosts.
9 And again, let all the records be had in order, that they may be put in the archives of my holy temple, to be held in remembrance from generation to generation, saith the Lord of Hosts.”
And section 128 reads:
“4 Then, let there be a general recorder, to whom these other records can be handed, being attended with certificates over their own signatures, certifying that the record they have made is true. Then the general church recorder can enter the record on the general church book, with the certificates and all the attending witnesses, with his own statement that he verily believes the above statement and records to be true, from his knowledge of the general character and appointment of those men by the church. And when this is done on the general church book, the record shall be just as holy, and shall answer the ordinance just the same as if he had seen with his eyes and heard with his ears, and made a record of the same on the general church book.
5 You may think this order of things to be very particular; but let me tell you that it is only to answer the will of God, by conforming to the ordinance and preparation that the Lord ordained and prepared before the foundation of the world, for the salvation of the dead who should die without a knowledge of the gospel.
6 And further, I want you to remember that John the Revelator was contemplating this very subject in relation to the dead, when he declared, as you will find recorded in Revelation 20:12--And I saw the dead, small and great, stand before God; and the books were opened; and another book was opened, which is the book of life; and the dead were judged out of those things which were written in the books, according to their works.
7 You will discover in this quotation that the books were opened; and another book was opened, which was the book of life; but the dead were judged out of those things which were written in the books, according to their works; consequently, the books spoken of must be the books which contained the record of their works, and refer to the records which are kept on the earth. And the book which was the book of life is the record which is kept in heaven; the principle agreeing precisely with the doctrine which is commanded you in the revelation contained in the letter which I wrote to you previous to my leaving my place--that in all your recordings it may be recorded in heaven.
8 Now, the nature of this ordinance consists in the power of the priesthood, by the revelation of Jesus Christ, wherein it is granted that whatsoever you bind on earth shall be bound in heaven, and whatsoever you loose on earth shall be loosed in heaven. Or, in other words, taking a different view of the translation, whatsoever you record on earth shall be recorded in heaven, and whatsoever you do not record on earth shall not be recorded in heaven; for out of the books shall your dead be judged, according to their own works, whether they themselves have attended to the ordinances in their own propria persona, or by the means of their own agents, according to the ordinance which God has prepared for their salvation from before the foundation of the world, according to the records which they have kept concerning their dead.
9 It may seem to some to be a very bold doctrine that we talk of--a power which records or binds on earth and binds in heaven. Nevertheless, in all ages of the world, whenever the Lord has given a dispensation of the priesthood to any man by actual revelation, or any set of men, this power has always been given. Hence, whatsoever those men did in authority, in the name of the Lord, and did it truly and faithfully, and kept a proper and faithful record of the same, it became a law on earth and in heaven, and could not be annulled, according to the decrees of the great Jehovah. This is a faithful saying. Who can hear it?
10 And again, for the precedent, Matthew 16:18, 19: And I say also unto thee, That thou art Peter, and upon this rock I will build my church; and the gates of hell shall not prevail against it. And I will give unto thee the keys of the kingdom of heaven: and whatsoever thou shalt bind on earth shall be bound in heaven; and whatsoever thou shalt loose on earth shall be loosed in heaven.
11 Now the great and grand secret of the whole matter, and the summum bonum of the whole subject that is lying before us, consists in obtaining the powers of the Holy Priesthood. For him to whom these keys are given there is no difficulty in obtaining a knowledge of facts in relation to the salvation of the children of men, both as well for the dead as for the living.
12 Herein is glory and honor, and immortality and eternal life--The ordinance of baptism by water, to be immersed therein in order to answer to the likeness of the dead, that one principle might accord with the other; to be immersed in the water and come forth out of the water is in the likeness of the resurrection of the dead in coming forth out of their graves; hence, this ordinance was instituted to form a relationship with the ordinance of baptism for the dead, being in likeness of the dead.
13 Consequently, the baptismal font was instituted as a similitude 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, as Paul hath declared, 1 Corinthians 15:46, 47, and 48:
14 Howbeit that was not first which is spiritual, but that which is natural; and afterward that which is spiritual. The first man is of the earth, earthy; the second man is the Lord from heaven. As is the earthy, such are they also that are earthy; and as is the heavenly, such are they also that are heavenly. And as are the records on the earth in relation to your dead, which are truly made out, so also are the records in heaven. This, therefore, is the sealing and binding power, and, in one sense of the word, the keys of the kingdom, which consist in the key of knowledge.
15 And now, my dearly beloved brethren and sisters, let me assure you that these are principles in relation to the dead and the living that cannot be lightly passed over, as pertaining to our salvation. For their salvation is necessary and essential to our salvation, as Paul says concerning the fathers--that they without us cannot be made perfect--neither can we without our dead be made perfect.
16 And now, in relation to the baptism for the dead, I will give you another quotation of Paul, 1 Corinthians 15:29: 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?
17 And again, in connection with this quotation I will give you a quotation from one of the prophets, who had his eye fixed on the restoration of the priesthood, the glories to be revealed in the last days, and in an especial manner this most glorious of all subjects belonging to the everlasting gospel, namely, the baptism for the dead; for Malachi says, last chapter, verses 5th and 6th: Behold, I will send you Elijah the prophet before the coming of the great and dreadful day of the Lord: And he shall turn the heart of the fathers to the children, and the heart of the children to their fathers, lest I come and smite the earth with a curse.
18 I might have rendered a plainer translation to this, but it is sufficiently plain to suit my purpose as it stands. It is sufficient to know, in this case, that the earth will be smitten with a curse unless there is a welding link of some kind or other between the fathers and the children, upon some subject or other--and behold what is that subject? It is the baptism for the dead. For we without them cannot be made perfect; neither can they without us be made perfect. Neither can they nor we be made perfect without those who have died in the gospel also; for it is necessary in the ushering in of the dispensation of the fulness of times, which dispensation is now beginning to usher in, that a whole and complete and perfect union, and welding together of dispensations, and keys, and powers, and glories should take place, and be revealed from the days of Adam even to the present time. And not only this, but those things which never have been revealed from the foundation of the world, but have been kept hid from the wise and prudent, shall be revealed unto babes and sucklings in this, the dispensation of the fulness of times.
19 Now, what do we hear in the gospel which we have received? A voice of gladness! A voice of mercy from heaven; and a voice of truth out of the earth; glad tidings for the dead; a voice of gladness for the living and the dead; glad tidings of great joy. How beautiful upon the mountains are the feet of those that bring glad tidings of good things, and that say unto Zion: Behold, thy God reigneth! As the dews of Carmel, so shall the knowledge of God descend upon them!
Proxy baptisms work in the same way that Christ's Atonement works for each and every man, woman, and child on this Earth--BY PROXY!!!
