Article of Faith 5

5 We believe that a man must be called of God, by prophecy, and by the laying on of hands by those who are in authority, to preach the Gospel and administer in the ordinances thereof.
We believe that the Priesthood authority was restored to Joseph Smith in these latter days. We believe that a man must be called of God and given this authority by the laying on of hands. There are many people who feel they are called of God, and act as if they have God's approval who have not received this ordination, and have not been called of God. Some begin churches, some act in God's name. But we believe, as is taught in Hebrews, "4 And no man taketh this honour unto himself, but he that is called of God, as was Aaron." Heb. 5:4

Elder Boyd K. Packer taught, "We do not call ourselves to offices in the Church. Rather we respond to the call of those who preside over us. It is the responsibility of those who preside to prayerfully consult the Lord as to His will concerning a position in the Church. Then the principle of revelation is at work. The call is then delivered by the presiding officer who is acting for the Lord." Boyd K. Packer, “What Every Elder Should Know—and Every Sister as Well: A Primer on Principles of Priesthood Government,” Ensign, Feb 1993, 7
