As revealed to the Prophet Joseph Smith, the higher or Melchizedek Priesthood comprehends or encompasses the Aaronic or Levitical Priesthood (4:207) and “holds the right of presidency, and has power and authority over all the offices in the church in all ages of the world” (D&C 107:8). Thus, the Melchizedek Priesthood administers “the keys of all the spiritual blessings of the church” and “the mysteries of the kingdom of heaven” (D&C 107:18–19).
