The word quorum can be used in two ways: A specified group of men who hold the same office of the priesthood. A majority, or the minimum number of members in a priesthood group that must be in attendance at a meeting to conduct the business of the Church (D&C 107: 28).

Quorums of the First Presidency, of the Twelve, and of the Seventy and their relationship to each other are described, D&C 107: 22-26, 33-34 (D&C 124: 126-128). Decisions of these quorums must be unanimous, D&C 107: 27. Decisions of a quorum are to be made in all righteousness, D&C 107: 30-32. Duties of presidents of priesthood quorums are described, D&C 107: 85-96. The quorum of elders is instituted for standing ministers, D&C 124: 137.
