"If therefore perfection were by the Levitical priesthood, (for under it the people received the law,) what further need was there that another priest should rise after the order of Melchisedek, and not be called after the order of Aaron? "For the priesthood being changed, there is made of necessity a change also of the law."[1] The apostle emphasizes the superiority of the Priesthood named after Melchisedek by affirming that Jesus Christ was a High Priest of that exalted order.[2] This Priesthood was held and exercised by the patriarchs in {235} turn from Adam to Moses. Aaron was ordained to the priest's office, as were his sons; but that Moses held superior authority is abundantly shown.[3] After Aaron's death his son Eleazar exercised the authority of High Priest of the Lesser Priesthood; and even Joshua had to ask of him counsel and instruction.[4] From the ministry of Moses to that of Christ the Lesser Priesthood alone was operative upon the earth, excepting only the instances of specially delegated authority of the higher order such as is manifest in the ministrations of certain chosen prophets, Isaiah, Jeremiah, Ezekiel and others. It is evident that these prophets, seers, and revelators, were individually and specially commissioned; but it appears that they had not the authority to call and ordain successors, for in their time the Higher Priesthood was not existent on earth in an organized state with duly officered quorums. Not so with the Aaronic or Levitical Priesthood, however, for the courses or quorums of that order were continued until the time of Christ. The last to hold and exercise the authority of the Aaronic Priesthood under the old or Mosaic dispensation was John the Baptist, who was specially commissioned. The matter is thus set forth in a modern revelation: "Now this Moses plainly taught to the children of Israel in the wilderness, and sought diligently to sanctify his people that they might behold the face of God; "But they hardened their hearts and could not endure his presence, therefore the Lord in his wrath (for his anger was kindled against them) swore that they should not enter into his rest while in the wilderness, which rest is the fulness of his glory. {236} "Therefore he took Moses out of their midst, and the Holy Priesthood also; "And the Lesser Priesthood continued, which priesthood holdeth the key of the ministering of angels and the preparatory gospel; "Which gospel is the gospel of repentance and of baptism, and the remission of sins, and the law of carnal commandments, which the Lord in his wrath, caused to continue with the house of Aaron among the children of Israel until John, whom God raised up, being filled with the Holy Ghost from his mother's womb;
