It was, not until the fifteenth day of May, 1829, that the young Prophet received authority to officiate in some of the ordinances of the Gospel of Jesus Christ. Joseph Smith and his scribe, Oliver Cowdery, had been engaged as usual on the translation of the sacred plates. On that day, they happened upon a passage referring to baptism. Since they knew nothing of the ordinance they became eager to understand. They went out into the wood to pray for light. Together they knelt upon the sod. United in their one great desire, they pleaded with the God of heaven to give them understanding. "While we were thus employed," writes the Prophet in his simple way, "praying and calling upon the Lord, a messenger from heaven descended in a cloud of light, and having laid his hands upon us, he ordained us, saying: "Upon you my fellow servants, in the name of Messiah, I confer the Priesthood of Aaron, which holds the keys of the ministering of angels, and of the gospel of repentance, and of baptism by immersion for the remission of sins; and this shall never be taken again from the earth, until the sons of Levi do offer again an offering unto the Lord in righteousness."[A] [Footnote A: "History of the Church," Vol. I, p. 15.] The messenger who appeared thus to Joseph and Oliver said that he was John the Baptist, and that he held the keys of the Aaronic priesthood from the dispensation of Christ. He explained further that this priesthood had not the power of laying on hands for the gift of the Holy Ghost. He commanded them to baptize each other, and to re-ordain each other after the pattern set them by him. Immediately Joseph and Oliver went to attend to the holy ordinance. First the Prophet baptized Oliver, then Oliver baptized the Prophet. The Prophet then laid his hands upon Oliver's head and ordained him to the Aaronic priesthood; and afterwards, Oliver ordained the Prophet. Both of them received thereupon glorious manifestations from heaven. They prophesied of things that were to be. They were filled with the Holy Ghost. And thus was consummated another act in the story of the Restoration. And what was this Priesthood restored by the heavenly messenger, John the Baptist? Priesthood is the authority to act in God's stead. Since the powers of God are infinite, so also must His priesthood be infinite. Therefore, what a man may or may not do in representing God, will depend upon the degree of authority he has received from the Great Master. One who has been commissioned with great authority may undertake great responsibilities for God; whereas one who has been commissioned with but little, can do but little. The principle of authority will not permit a man to attempt responsibilities greater than his priesthood, though he may feel himself otherwise competent to do them fully as well as does the man who holds the necessary authority. Thus divine authority--or priesthood--becomes a power highly to be respected.
