[Footnote B: This was the Bishop's agent.] "There are, in the Church, two Priesthoods, namely, the Melchizedek, and Aaronic, including the Levitical Priesthood. Why the first is called the Melchizedek Priesthood is because Melchizedek was such a Great High Priest. Before his day it was called _the Holy Priesthood after the order of the Son of God_; 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. _All other authorities or offices_ in the Church _are appendages_ to this Priesthood: but there are two divisions or grand heads--one is the Melchizedek Priesthood, and the other is the Aaronic or Levitical Priesthood. The office of an Elder comes under the Priesthood of Melchizedek. The Melchizedek Priesthood holds the right of Presidency, and has power and authority over all the offices in the Church, in all ages of the world, to administer in spiritual things. _The Presidency of the High Priesthood after the order of Melchizedek, have a right to officiate in all the offices_ in the Church."--Sec. 107, pars. 1-9, pp. 383-4. Thus the Melchizedek Priesthood holds the right of Presidency, and has power and authority over all the offices in the Church, to administer in spiritual things, while the Presidency of the High Priesthood has a right to officiate in all the offices in the Church. "This is the duty of a Bishop who is not a literal descendant of Aaron, but has been ordained to the High Priesthood after the order of Melchizedek. 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."--Sec. 107, pars. 73-75, p. 391. (See all of this section.) He was to be a common judge among the inhabitants of Zion, or in a Stake of Zion, or in a branch of the Church, _when he shall be set apart unto his ministry_. His Bishopric is sufficient for any of these places when set apart: and he can only fill those offices for which he is set apart. 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, without Counselors, except in a case when a President of the High Priesthood is tried.
