A person authorized of God to see with spiritual eyes things which God has hidden from the world (Moses 6: 35-38). He is a revelator and a prophet (Mosiah 8: 13-16). In the Book of Mormon, Ammon taught that only a seer could use special interpreters, or a Urim and Thummim (Mosiah 8: 13; 28: 16). A seer knows the past, present, and future. Anciently, a prophet was often called a seer (1 Sam. 9: 9; 2 Sam. 24: 11).

Joseph Smith is the great seer of the latter days (D&C 21: 1; 135: 3). In addition, the First Presidency and the Council of the Twelve are sustained as prophets, seers, and revelators.

This is a rebellious people that say to the seers, See not; and to the prophets, Prophesy not, Isa. 30: 9-10. A choice seer will I raise up out of the fruit of thy loins, 2 Ne. 3: 6-15. Here is wisdom; yea, to be a seer, a revelator, a translator, and a prophet, D&C 107: 92. The Lord appointed Hyrum Smith to be a prophet, seer, and revelator to the Church, D&C 124: 91-94.
