"What Is The Meaning Of
"The three separate titles in the general title have much the same meaning in popular usage, yet there are differences sufficiently important to justify their use.

"A prophet is a teacher. That is the essential meaning of the word. He teaches the body of truth, the gospel, revealed by the Lord to man; and under inspiration explains it to the understanding of the people. He is an expounder of truth. Moreover, he shows that the way to human happiness is through obedience to God's law. He calls to repentance those who wander away from the truth. He becomes a warrior for the consummation of the Lord's purposes with respect to the human family. The purpose of his life is to uphold the Lord's plan of salvation. All this he does by close communion with the Lord, until he is 'full of power by the spirit of the Lord.' (Micah 3:8; see also D&C 20:26; 34:10; 43:16)
"The teacher must learn before he can teach. Therefore in ancient and modern times there have been schools of the prophets, in which the mysteries of the kingdom have been taught to men who would go out to teach the gospel and to fight the battles of the Lord. These 'prophets' need not be called to an office; they go out as teachers of truth, always and everywhere.

"A prophet also receives revelations from the Lord. These may be explanations of truths already received, or new truths not formerly possessed by man. Such revelations are always confined to the official position held. The lower will not receive revelations for the higher office.

"In the course of time the word 'prophet' has come to mean, perhaps chiefly, a man who receives revelations, and directions from the Lord. The principal business of a prophet has mistakenly been thought to foretell coming events, to utter prophecies, which is only one of the several prophetic functions.

"In the sense that a prophet is a man who receives revelations from the Lord, the titles 'seer and revelator' merely amplify the larger and inclusive meaning of the title 'prophet.' Clearly, however, there is much wisdom in the specific statement of the functions of the prophet as seer and revelator, as is done in the conferences of the Church.

"A seer is one who sees with spiritual eyes. He perceives the meaning of that which seems obscure to others; therefore he is an interpreter and clarifier of eternal truth. He foresees the future from the past and the present. This he does by the power of the Lord operating through him directly, or indirectly with the aid of divine instruments such as the Urim and Thummim. In short, he is one who sees, who walk in the Lord's light with open eyes. (Book of Mormon, Mosiah 8:15-17)

"A revelator makes known, with the Lord's help, something before unknown. It may be new or forgotten truth, or a new or forgotten application of known truth to man's need. Always, the revelator deals with truth, certain truth (D&C 100:11) and always it comes with the divine stamp of approval. Revelation may be received in various ways, but it always presupposes that the revelator has so lived and conducted himself as to be in tune or harmony with the divine spirit of revelation, the spirit of truth, and therefore capable of receiving divine messages.

"In summary: A prophet is a teacher of known truth; a seer is a perceiver of hidden truth, a revelator is a bearer of new truth. In the widest sense, the one most commonly used, the title, prophet, includes the other titles and makes of the prophet, a teacher, perceiver, and bearer of truth." - (Apostle) Elder John A. Widtsoe, (1960). Evidences and Reconciliations, Salt Lake City: Bookcraft, 25658.

What Is a Seer?

A seer is one who sees "things which [are] not visible to the natural eye" ( Moses 6:36 ). By seeing through his "spiritual eyes" ( Moses 1:11 ), a seer obtains knowledge of truths beyond the vision of other mortals. By seeing in vision that to which God opens to the "eyes of [his] understanding" ( D&C 110:1 ; 76:12 ), a seer is able to see whatever is expedient in the past, present, or future and is able to interpret and clarify eternal truths. Enoch and Moses are scriptural examples of seers (see Moses 1:811, 2729 ; 6:3536 ; 7:2167 .) The following account from the Book of Mormon teaches several significant concepts about the role of a seer:

"Now Ammon said unto him: I can assuredly tell thee, O king, of a man that can translate the records; for he has wherewith that he can look, and translate all records that are of ancient date; and it is a gift from God. And the things are called interpreters, and no man can look in them except he be commanded, lest he should look for that he ought not and he should perish. And whosoever is commanded to look in them, the same is called seer.

"And behold, the king of the people who are in the land of Zarahemla is the man that is commanded to do these things, and who has this high gift from God.

"And the king said that a seer is greater than a prophet.

"And Ammon said that a seer is a revelator and a prophet also; and a gift which is greater can no man have, except he should possess the power of God, which no man can; yet a man may have great power given him from God.

"But a seer can know of things which are past, and also of things which are to come, and by them shall all things be revealed, or, rather, shall secret things be made manifest, and hidden things shall come to light, and things which are not known shall be made known by them, and also things shall be made known by them which otherwise could not be known." ( Mosiah 8:1317 .)

Elder Orson F. Whitney explained the role of a seer in this way:

"A seer is greater than a prophet [see Mosiah 8:15 ]. One may be a prophet without being a seer; but a seer is essentially a prophet--if by 'prophet' is meant not only a spokesman, but likewise a foreteller. Joseph Smith was both prophet and seer.

"A seer is one who sees. But it is not the ordinary sight that is meant. The seeric gift is a supernatural endowment. Joseph was 'like unto Moses;' and Moses, who saw God face to face, explains how he saw him in these words: 'Now mine own eyes have beheld God; yet not my natural, but my spiritual eyes; for my natural eyes could not have beheld; for I should have withered and died in his presence; but his glory was upon me; and I beheld his face, for I was transfigured before him.' [ Moses 1:11 .] Such is the testimony of the ancient Seer, as brought to light by the Seer of Latter-days [Joseph Smith]." ( Saturday Night Thoughts, pp. 3940.)
