The Bishops stand at the head the Aaronic or lesser Priesthood, an appendage to the higher of Melchisedek Priesthood. {36} There are three who form the Presiding Bishopric of the Church. Other Bishops have charge of wards of the Church, and the function of the Bishopric is to minister in the temporalities of the Church. Priests, forty-eight of whom form a "quorum," presided over by a Bishop and two counselors; Teachers, twenty-four of whom form a "quorum," presided over by three of their number; and Deacons, twelve of whom form a "quorum," presided over by three of their number, constitute the rest of the organizations of the lesser Priesthood. They exist in all the wards, and are under the direction of the respective Bishoprics. Apostles, Patriarchs, Seventies, High Priests and Elders may preach, baptize and lay on hands for the gift of the Holy Ghost, and perform any duty of the Aaronic Priesthood, as the greater includes the less. Aaronic Priests may preach, teach and baptize for the remission of sins, but cannot confer the Holy Ghost by the laying on of hands. Teachers visit the members and see there is no iniquity permitted to remain in the Church. Deacons attend to temporal duties under the Bishops. A Bishop should be a lineal descendant of Aaron, but in the absence of one of that lineage, a High Priest is selected and ordained to that office. With his two counselors, also High Priests, he has charge of an organized ward and sits in judgment upon transgressors and in cases of disputes between members. An appeal is allowed to the High Council. Members residing in a given locality form a ward. A number of wards, generally those within a county, are organized into a Stake of Zion, presided over by three High Priests. A High Council, consisting of twelve High Priests, constitutes an ecclesiastical tribunal, to which appeals may be taken from decisions of the Bishops' courts. It is presided over by the Stake Presidency, who have jurisdiction over all the wards and their officers in the Stake. There are now fifty-five of these Stakes of Zion and a number of conferences and mission organizations in addition. A High Council decision is subject to review by the Presidency of the Church. All the officers of the Church are presented twice a year before the body of the Church for their acceptance or rejection. The Stake and ward authorities are periodically subject to a similar regulation. All serve without salaries. Persons engaged constantly in Church service are supported, or partly sustained, according to needs, from Church funds. Missionaries have no stipends, but travel "without purse or scrip," either paying their own expenses or relying upon friends whom the Lord raises up to their aid.
