"A seer is a revelator and a prophet also" (Mosiah 8: 15-16), and when necessary he can use the Urim and Thummim or holy interpreters (Mosiah 8: 13; Mosiah 28: 16). There have been many seers in the history of God's people on this earth, but not so many as there have been prophets. "A seer is greater than a prophet . . . and a gift which is greater can no man have . . . " (Mosiah 8: 15-18). Joseph Smith is the great seer of the latter days. In addition, the First Presidency, the Council of the Twelve, and the Patriarch to the Church are sustained as prophets, seers, and revelators.
