The term derives in part from the Epistle to the Hebrews, which describes Jesus as "a high priest after the order of Melchizedek" (5:10; see also 6:20).
[2] Like other priesthood offices in the LDS Church, high priests are organized into quorums.
(In contrast, priesthood quorums for the offices of deacon, teacher, priest, and elder are organized at the ward level.)
However, following changes announced in the April 2018 general conference, the high priest groups were disbanded at the ward level.
High priests not currently serving in those callings are members of their ward's elders quorum.
