It makes no difference what is written or what anyone has said, if what has been said is in conflict with what the Lord has revealed, we can set it aside. My words, and the teachings of any other member of the Church, high or low, if they do not square with the revelations, we need not accept them. Let us have this matter clear. We have accepted the four standard works as the measuring yardsticks, or balances, by which we measure every man’s doctrine.
So, to those who propagate the meme that the words of the sitting prophet supersede the canon (as you occasionally hear in church classes, particularly around general conference time), i would like to point out that it was a prophet who said otherwise.
