If we would understand both the history and the doctrine of temple work we must understand what the sealing power is. I'm pretty sure chemists and physicists are working on that right now. We will crack the code! We must envision, at least to a degree, why the keys of authority to employ the sealing power are crucial. Self importance, perhaps?
Nearly nine hundred years before Christ, the prophet Elijah appeared in the court of the king of Israel. He carried with him a sacred authority: the power to seal. You don't think this story's made up?? I mean, it's from the Old Testament for crying out loud.
Elijah worked out his ministry, ordained and anointed Elisha to succeed him, and then—and this is important—he did not die. Like Moses before him, he was translated. Could he also fly and see through walls?
After that, his name appears only once in the Old Testament, in the next to the last verse of the last chapter of the Old Testament. It is here that Malachi prophesies that Elijah would return and that he would “turn the heart of the fathers to the children, and the heart of the children to their fathers,” lest the whole earth be smitten with a curse. (See Malachi 4:5–6.) I really and truly hate curses. Please tell me Elijah flew back in from wherever he flew off to.
You didn't transition at all to these verses. How did you get from Malachi talking hearts to Matthew talking stones and keys so fast?When Jesus came into the coasts of Caesarea Philippi, he asked his disciples, saying, Whom do men say that I the Son of man am?And they said, Some say that thou art John the Baptist: some, Elias; and others, Jeremias, or one of the prophets.He saith unto them, But whom say ye that I am?And Simon Peter answered and said, Thou art the Christ, the Son of the living God.And Jesus answered and said unto him, Blessed art thou, Simon Bar-jona: for flesh and blood hath not revealed it unto thee, but my Father which is in heaven.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. (Matthew 16:13–19.)
When Peter, James, and John went with the Lord to the Mount of Transfiguration, there appeared with the transfigured Lord two personages. It's all true, isn't it? Please tell me there are dead people that can come back and float in the air as we levitate. They recognized them to be Moses and Elijah, who had come to convey to that presidency the sealing power. (See Matthew 17:1–8; note that Elias is the Greek translation of the Hebrew name Elijah and is often used in the New Testament to designate Elijah, the prophet of the Old Testament.) If only Joseph Smith knew what you just shared with us he wouldn't look like such an ass today.
Peter was to hold the keys. Is that a euphemism for touching one's cock and balls? Peter was to hold the sealing power, that authority which carries the power to bind or seal on earth or to loose on earth and it would be so in the heavens. He could make thinks in the sky the same as on the ground? You need to explain this better. Maybe what you mean is that he had a special glue for his model rockets so they wouldn't fall apart in the air.
In A.D. 34, after His crucifixion, the Lord ministered to the Nephites. That's miraculous because the Nephites are a fiction. He dictated to them—and this is remarkable in scriptural history—the last two chapters of Malachi (which contained the prophecy that Elijah would return), caused them to write them, and then expounded them. What's truly miraculous here is that the Lord dictated from the King James Bible, which was still about 1600 years in the making. Or Joseph just copied them down from his Bible at home and threw in his preferred interpretation.
When the Angel Moroni appeared to the Prophet Joseph Smith to tell him of the plates, he quoted Malachi’s prophecy that Elijah would return. According to one version of the story. This quotation is now section two of the Doctrine and Covenants. So thanks to Joseph Smith, Malachi is now canonized in Jacobian English in 3 different books of scripture. Impressive.
Thirteen years after Moroni appeared, a temple had been built adequate for the purpose, and the Lord again appeared and Elijah came with Him and bestowed the keys of the sealing power. He returned again? That's dedication! Unfortunately he got back too late to help Joseph authorize his first plural marriage. Oops.
Those keys belong to the President of the Church—to the prophet, seer, and revelator. Today it's a man who has neither prophesied, seen or revealed anything on behalf of the Church. Despite those shortcomings, don't doubt that he is definitely holding fast to those keys. That sacred sealing power is with the Church now. Says the Church. Nothing is regarded with more sacred contemplation by those who know the significance of this authority. What is that significance? You haven't really said. Nothing is more closely held. Because of greed or fear? What would happen if those keys were conferred on an evil man? Would God help you find these keys again if you accidentally lost them? There are relatively few men who hold this sealing power upon the earth at any given time—in each temple are brethren who have been given the sealing power. Our holy chefs of the original recipe... No one can get it except from the prophet, seer, and revelator and President of The Church of Jesus Christ of Latter-day Saints or from those he has delegated to give it to others. This is why you have to go with LDS Mormonism. Don't settle for anything less than the most powerful sealing contractors in the business!
