who holds priesthood keys in the lds church
Priesthood (Latter Day Saints) Priesthood keys are conferred upon all the presidents of the quorums. A quorum is a group of priesthood holders who hold the same priesthood office. For a priesthood holder to exercise ecclesiastical power or authority, Latter Day Saints believe that a priesthood holder must have a specific set of keys or be authorized by one who holds those keys. Thus, even though a priesthood holder is called and ordained with general priesthood power, to formally lead others in the church or to conduct specific rites may also require specific keys not held by all priesthood holders. The existence of keys makes possible a church hierarchy, in which particular priesthood holders specialize in a particular ecclesiastical function organized in a top-down manner.[26]
