Requirements for Ordination

The Priesthood is conferred on male church-members beginning at age twelve by the laying on of hands of men previously ordained to the Priesthood. Ordination to the Priesthood is based on the recipient's personal moral worthiness without regard to education or other socio-economic status, and, since 1978, without regard to race. Thus, every worthy male Church member is typically ordained to be a priest (in a general sense of minister, not necessarily as the office of priest below) and the Church is led by a lay clergy who are not paid for their services; the Priesthood is not a profession nor restricted to privileged persons. Not including employees who run the Church's global business affairs from its offices in Salt Lake City, only Apostles in the Church—having left their (usually lucrative) careers to serve for life in that capacity—receive compensation: a living stipend.

If an adult man joins the Church, he may be called and ordained to hold the Aaronic Priesthood (if he is morally worthy) by those in the Church with authority to do so. After a period of time (usually one year) the man may be called and ordained to receive the Melchizedek Priesthood (again based upon moral worthiness) by those in the Church with authority. In addition to being ordained to a certain office in the Aaronic or Melchizedek Priesthood, a male may also be set apart and ordained to a Priesthood leadership office. For example, men are usually not ordained to the office of High Priest unless they are also set apart to an office which requires that ordination, such as Bishop or High Councilman. However, older men are also ordained to the office of High Priest although they may have never been set apart to serve in a leadership office. Each person who holds an office of the Aaronic or Melchizedek Priesthood also belong to a local Priesthood quorum.

Priesthood Leadership Callings

In addition to the regular offices of the Aaronic or Melchizedek Priesthood referred to in the chart above, there are other leadership callings within the Aaronic and Melchizedek Priesthoods. The table below lists these other Priesthood leadership callings and the table below it shows how the various callings are organized within the hierarchy of the Church.

Church Leadership, Quorum Organization and Filling Vacant Callings

In the Church, Apostles are a council of fifteen ordained men who are called to be special witnesses of Jesus Christ, to govern and administer to the entire Church and to hold the highest Priesthood authority in the Church for life. Each of these Apostles is also ordained as a "Prophet, Seer and Revelator" and each Apostle holds all the "keys of the Priesthood". However, these keys and callings are dormant until the Apostle is entitled to exercise them. Thus, only the President and Prophet of the Church is entitled to receive revelation for the entire Church. Typically, the most senior member of the group (in years served as an Apostle) is also ordained as the President and Prophet of the Church. The President is generally supported by two Apostles who he selects as his counselors, although certain Presidents—generally with health problems—have chosen to select additional counselors. The Prophet and his counselors compose the First Presidency. The remaining Apostles compose the Quorum of the Twelve Apostles, the most senior member of that quorum typically being the President of that quorum. The members of the First Presidency and the Quorum of the Twelve Apostles are called to their positions for life and serve until death. As vacancies arise in the Quorum of the Twleve Apostles, all of the Apostles meet to pray and to come to a unanimous decision by revelation as to whom among the rank and file of the Church will be called to fill the vacancy. The Apostles then ordain the appointed man called.

The Quorum of the Twelve Apostles was instituted on February 14, 1835, (Doctrine and Covenants 107:23-24) and is equal in authority to The First Presidency in absentia. The First Presidency dissolves whenever the President of the First Presidency is no longer serving in that capacity—so far only because of death. When the First Presidency dissolves, the counselors of the First Presidency become part of the Quroum of the Twelve Apostles until a new First Presidency is organized. The First Quorum of the Seventy was set up February 28, 1835, (Documentary History of the Church 2:201-2) and these quorums are equal in authority to the Quorum of the Twelve Apostles in absentia. In Mormon theology when Jesus Christ comes again to personally reign on the earth, He will personally take the place of the office of the First Presidency as he did during his earthly ministry in the New Testament.
