Aaronic priesthood (Latter Day Saints)

The Aaronic priesthood (; also called the priesthood of Aaron or the Levitical priesthood) is the lesser of the two (or sometimes three) orders of priesthood recognized in the Latter Day Saint movement. The others are the Melchizedek priesthood and the rarely recognized Patriarchal priesthood. Unlike the Melchizedek priesthood, which is modeled after the authority of Jesus and the Twelve Apostles, or the Patriarchal priesthood, which is modeled after the authority of Abraham, the Aaronic priesthood is modeled after the priesthood of Aaron the Levite, the first high priest of the Hebrews, and his descendents. The Aaronic priesthood is thought to be a lesser or preparatory priesthood and an "appendage" of the more powerful Melchizedek priesthood.
