JohnD,
One of the aspects of thought is also communication. God the Father communited to the prophets in various ways. Dreams, visions, angels and perhaps Christ preexisting as the angel of the Lord when wrestling Jacob, even directly in a way with Moses. Thought also is cognition. It is one of the main thoughts that we are to have a relationship with God, and this requires thoughtful communication. When God created time, it is all possible that he does not think like we do, but he does think... and communicates that thought to us in various degrees.
I certainly do not agree with your first paragraph also. There can be progressive understandings, but that does not bury the truth but only make truth much more clear and concise. Much of the heresies are based on improper approaches to what has already been accepted as authoritative. The Torah came before the Prophets, and the N.T. came much later. Progessive. I'll come back later to discuss this. I just don't think you should be so negative about tradition, tradition is a progressive and consistent thing.opinions become discussions, discussions become beliefs, beliefs become traditions and touted as authoritative
