I disagree that his word means more than scripture.
Then you are misunderstanding doctrine- the Prophet's words are modern scripture. That is where D&C comes from. I am sure over time more will be added to it but in the mean time we have conference talks and General Authroirty's messages in addition to the Bible, BoM, D&C, and PoGP.
