In the Latter Day Saint movement, a bishop is the highest office of the Aaronic priesthood. It is almost always held by one who holds the office of high priest in the Melchizedek priesthood. The Latter Day Saint concept of the office differs significantly from the role of bishops in other Christian denominations, being in some respects more analogous to a pastor or parish priest. Each bishop serves with two counselors, who together form a bishopric.
The role of a bishop varies in the different Latter Day Saint denominations; however, they derive from a common history.
