We call these the standard Church works because they are standard. If you want to measure truth, measure it by the four standard Church works. … If it is not in the standard works, you may well assume that it is speculation. It is man's own personal opinion, to put it another way; and if it contradicts what is in the scriptures, you may know by that same token that it is not true. This is the standard by which you measure all truth. But if you do not know the standards, you have no adequate measure of truth.

If we want to measure truth, we should measure it by the four standard works, regardless of who writes it.

The living prophet is more vital to us than the Standard Works.

President Wilford Woodruff tells of an interesting incident that occurred in the days of the Prophet Joseph Smith:

"I will refer to a certain meeting I attended in the town of Kirtland in my early days. At that meeting some remarks were made that have been made here today, with regard to the living prophets and with regard to the written word of God. The same principle was presented, although not as extensively as it has been here, when a leading man in the Church got up and talked upon the subject, and said: 'You have got the word of God before you here in the Bible, Book of Mormon, and Doctrine and Covenants; you have the written word of God, and you who give revelations should give revelations according to those books, as what is written in those books is the word of God. We should confine ourselves to them.'

"When he concluded, Brother Joseph turned to Brother Brigham Young and said, 'Brother Brigham I want you to go to the podium and tell us your views with regard to the living oracles and the written word of God.' Brother Brigham took the stand, and he took the Bible, and laid it down; he took the Book of Mormon, and laid it down; and he took the Book of Doctrine and Covenants, and laid it down before him, and he said: 'There is the written word of God to us, concerning the work of God from the beginning of the world, almost, to our day. And now,' said he, 'when compared with the living oracles those books are nothing to me; those books do not convey the word of God direct to us now, as do the words of a Prophet or a man bearing the Holy Priesthood in our day and generation. I would rather have the living oracles than all the writing in the books.' That was the course he pursued. When he was through, Brother Joseph said to the congregation; 'Brother Brigham has told you the word of the Lord, and he has told youthe truth.' " (Conference Report, October 1897, pp. 18-19.)

President Ezra Taft Benson said that the "living prophet is more vital to us than the standard works" ("Fourteen Fundamentals in Following the Prophet," in Speeches of the Year, 1980 [Provo: Brigham Young University, 1981], p. 26).
