DOCTRINE AND COVENANTS
OF THE CHURCH OF JESUS CHRIST OF LATTER-DAY SAINTS
Ordination of Joseph Smith and Oliver Cowdery to the Aaronic Priesthood along the bank of the Susquehanna River, near Harmony, Pennsylvania, May 15, 1829. HC 1: 39-42. The ordination was done by the hands of an angel, who announced himself as John, the same that is called John the Baptist in the New Testament. The angel explained that he was acting under the direction of Peter, James, and John, the ancient apostles, who held the keys of the higher priesthood, which was called the Priesthood of Melchizedek. The promise was given to Joseph and Oliver that in due time the Priesthood of Melchizedek would be conferred upon them. See also Section 27: 7, 8, 12.
Keys and powers of Aaronic Priesthood are set forth.
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.
