1–6, There are two priesthoods: the Melchizedek and the Aaronic; 7–12, Those who hold the Melchizedek Priesthood have power to officiate in all offices in the Church; 13–17, The bishopric presides over the Aaronic Priesthood, which administers in outward ordinances; 18–20, The Melchizedek Priesthood holds the keys of all spiritual blessings; the Aaronic Priesthood holds the keys of the ministering of angels; 21–38, The First Presidency, the Twelve, and the Seventy constitute the presiding quorums, whose decisions are to be made in unity and righteousness; 39–52, The patriarchal order is established from Adam to Noah; 53–57, Ancient Saints assembled at Adam-ondi-Ahman, and the Lord appeared to them; 58–67, The Twelve are to set the officers of the Church in order; 68–76, Bishops serve as common judges in Israel; 77–84, The First Presidency and the Twelve constitute the highest court in the Church; 85–100, Priesthood presidents govern their respective quorums.
4 But out of respect or reverence to the name of the Supreme Being, to avoid the too frequent repetition of his name, they, the church, in ancient days, called that priesthood after Melchizedek, or the Melchizedek Priesthood.
10 High priests after the order of the Melchizedek Priesthood have a right to officiate in their own standing, under the direction of the presidency, in administering spiritual things, and also in the office of an elder, priest (of the Levitical order), teacher, deacon, and member.
12 The high priest and elder are to administer in spiritual things, agreeable to the covenants and commandments of the church; and they have a right to officiate in all these offices of the church when there are no higher authorities present.
17 But as a high priest of the Melchizedek Priesthood has authority to officiate in all the lesser offices, he may officiate in the office of bishop when no literal descendant of Aaron can be found, provided he is called and set apart and ordained unto this power by the hands of the Presidency of the Melchizedek Priesthood.
19 To have the privilege of receiving the mysteries of the kingdom of heaven, to have the heavens opened unto them, to commune with the general assembly and church of the Firstborn, and to enjoy the communion and presence of God the Father, and Jesus the mediator of the new covenant.
20 The power and authority of the lesser, or Aaronic Priesthood, is to hold the keys of the ministering of angels, and to administer in outward ordinances, the letter of the gospel, the baptism of repentance for the remission of sins, agreeable to the covenants and commandments.
22 Of the Melchizedek Priesthood, three Presiding High Priests, chosen by the body, appointed and ordained to that office, and upheld by the confidence, faith, and prayer of the church, form a quorum of the Presidency of the Church.
23 The twelve traveling councilors are called to be the Twelve Apostles, or special witnesses of the name of Christ in all the world—thus differing from other officers in the church in the duties of their calling.
25 The Seventy are also called to preach the gospel, and to be especial witnesses unto the Gentiles and in all the world—thus differing from other officers in the church in the duties of their calling.
27 And every decision made by either of these quorums must be by the unanimous voice of the same; that is, every member in each quorum must be agreed to its decisions, in order to make their decisions of the same power or validity one with the other—
29 Unless this is the case, their decisions are not entitled to the same blessings which the decisions of a quorum of three presidents were anciently, who were ordained after the order of Melchizedek, and were righteous and holy men.
30 The decisions of these quorums, or either of them, are to be made in all righteousness, in holiness, and lowliness of heart, meekness and long-suffering, and in faith, and virtue, and knowledge, temperance, patience, godliness, brotherly kindness and charity;
32 And in case that any decision of these quorums is made in unrighteousness, it may be brought before a general assembly of the several quorums, which constitute the spiritual authorities of the church; otherwise there can be no appeal from their decision.
33 The Twelve are a Traveling Presiding High Council, to officiate in the name of the Lord, under the direction of the Presidency of the Church, agreeable to the institution of heaven; to build up the church, and regulate all the affairs of the same in all nations, first unto the Gentiles and secondly unto the Jews.
34 The Seventy are to act in the name of the Lord, under the direction of the Twelve or the traveling high council, in building up the church and regulating all the affairs of the same in all nations, first unto the Gentiles and then to the Jews—
36 The standing high councils, at the stakes of Zion, form a quorum equal in authority in the affairs of the church, in all their decisions, to the quorum of the presidency, or to the traveling high council.
42 From Adam to Seth, who was ordained by Adam at the age of sixty-nine years, and was blessed by him three years previous to his (Adam’s) death, and received the promise of God by his father, that his posterity should be the chosen of the Lord, and that they should be preserved unto the end of the earth;
43 Because he (Seth) was a perfect man, and his likeness was the express likeness of his father, insomuch that he seemed to be like unto his father in all things, and could be distinguished from him only by his age.
49 And he saw the Lord, and he walked with him, and was before his face continually; and he walked with God three hundred and sixty-five years, making him four hundred and thirty years old when he was translated.
53 Three years previous to the death of Adam, he called Seth, Enos, Cainan, Mahalaleel, Jared, Enoch, and Methuselah, who were all high priests, with the residue of his posterity who were righteous, into the valley of Adam-ondi-Ahman, and there bestowed upon them his last blessing.
56 And Adam stood up in the midst of the congregation; and, notwithstanding he was bowed down with age, being full of the Holy Ghost, predicted whatsoever should befall his posterity unto the latest generation.
72 And also to be a judge in Israel, to do the business of the church, to sit in judgment upon transgressors upon testimony as it shall be laid before him according to the laws, by the assistance of his counselors, whom he has chosen or will choose among the elders of the church.
74 Thus shall he be a judge, even a common judge among the inhabitants of Zion, or in a stake of Zion, or in any branch of the church where he shall be set apart unto this ministry, until the borders of Zion are enlarged and it becomes necessary to have other bishops or judges in Zion or elsewhere.
76 But a literal descendant of Aaron has a legal right to the presidency of this priesthood, to the keys of this ministry, to act in the office of bishop independently, without counselors, except in a case where a President of the High Priesthood, after the order of Melchizedek, is tried, to sit as a judge in Israel.
78 Again, verily, I say unto you, the most important business of the church, and the most difficult cases of the church, inasmuch as there is not satisfaction upon the decision of the bishop or judges, it shall be handed over and carried up unto the council of the church, before the Presidency of the High Priesthood.
79 And the Presidency of the council of the High Priesthood shall have power to call other high priests, even twelve, to assist as counselors; and thus the Presidency of the High Priesthood and its counselors shall have power to decide upon testimony according to the laws of the church.
82 And inasmuch as a President of the High Priesthood shall transgress, he shall be had in remembrance before the common council of the church, who shall be assisted by twelve counselors of the High Priesthood;
85 And again, verily I say unto you, the duty of a president over the office of a deacon is to preside over twelve deacons, to sit in council with them, and to teach them their duty, edifying one another, as it is given according to the covenants.
86 And also the duty of the president over the office of the teachers is to preside over twenty-four of the teachers, and to sit in council with them, teaching them the duties of their office, as given in the covenants.
87 Also the duty of the president over the Priesthood of Aaron is to preside over forty-eight priests, and sit in council with them, to teach them the duties of their office, as is given in the covenants—
98 Whereas other officers of the church, who belong not unto the Twelve, neither to the Seventy, are not under the responsibility to travel among all nations, but are to travel as their circumstances shall allow, notwithstanding they may hold as high and responsible offices in the church.
