The priesthood is the authority of God delegated to men on the earth to act in all things for the salvation of mankind (see Spencer W. Kimball, “The Example of Abraham,” Ensign, June 1975, 3). Priesthood is the means whereby the Lord acts through men to save souls. One of the defining features of the Church of Jesus Christ, both anciently and today, is His authority. There can be no true Church without divine authority.
