Deacon is a priesthood office in the Aaronic priesthood of denominations within the Latter Day Saint movement, including The Church of Jesus Christ of Latter-day Saints (LDS Church).
In the LDS Church, deacon is the lowest of four offices of the Aaronic priesthood. Male members of the church may become deacons at age 12. A bishop may give approval for such members to receive the Aaronic priesthood and ordained to the office of deacon. Prior to ordination, the candidate must have an interview with the bishop or one of his counselors and the proposed ordination must be accepted by common consent by the members of the ward. With the bishop's approval, a person who holds the office of priest or a holder of the Melchizedek priesthood is able to perform the ordination of a deacon by the laying on of hands.
Deacons in a ward are organized in quorums. The Doctrine and Covenants states that a president of a deacons quorum can preside over 12 deacons. As a result, in some large wards, there may be two or more quorums of deacons. From the members of each deacons quorum, a president, first counselor, second counselor, and secretary may be called and set apart by the bishopric. The president and his two counselors constitute the deacons quorum presidency. The president of the deacons quorum is given priesthood keys by the laying on of hands by the bishop to preside over the members of his quorum. The members of the deacons quorum presidency and the secretary may not be set apart until after they have been accepted by the common consent of the members of the quorum.
