In Mormonism, the Melchizedek priesthood ( /mɛlˈkɪzɪdɛk/), also referred to as the high priesthood of the holy order of God or the Holy Priesthood, after the Order of the Son of God, is the greater of the two orders of priesthood, the other being the Aaronic priesthood. According to Joseph Smith, the name of this priesthood became Melchizedek "because Melchizedek was such a great high priest" and "to avoid the too frequent repetition" of the "name of the Supreme Being".
