This topic reminds me of a quote by Robert Millet from the recently published Claiming Christ:
“It’s a little tough to answer the question: Which is of greater importance to you people, the living prophet or the standard works (another way of describing our scriptural canon)? I think most Latter-day Saints would be prone to answer this by pointing out the value and significance of living oracles, or continuing revelation, or ongoing divine direction through modern apostles and prophets, and thus to conclude that living prophets take precedence over canonized scripture. On the other hand, a number of LDS Church leaders have commented that while Mormons look to living prophets and modern revelation as their guide to walk and talk in modern times, they are quick to add that prophetic pronouncement will be in harmony with the standard works, the canon. For this perspective, then, it appears that the standard works trump the living prophets. And so to be honest, it’s a little tough to decide which is the chicken and which is the egg.”
