Then it seems that we agree that our understanding can grow. Now let's discuss this "needs no embellishment."
If the body of truth does not change, but our understanding does, are we forbidden to try to capture this better understanding? To write it down, classify, clarify, define it? If something is true by revelation or true by deduction isn't it still true? If we name a concept of this understanding, even if the name isn't in Scripture, isn't it still true?
If it needs no embelishment, why do we type these words? Why do we make textbooks for our children? Why do we print study guides and concordances?

Something that you try to make true with logic does not trump that which already is true through the spirit. If the Bible says no talking to the dead, artful words don't make it true that you are allowed to anyway.
