But what is being stored, and how are we to regard it? Do you claim that the Bible is both a complete and solely authoritative record of God's word? Solely authoritative but not complete? Complete (to a point) but not solely authoritative?
It seems nitpicky, but in many respects those (and other) views of "repository" are characteristic of the various players in the many religious controversies we see around us.
Out of all of human history, and some history of the heavenlies, and out of all the words and deeds prompted or committed by God, the Bible contains those God considered necessary.
It does not surprise me that God’s Word is handled in a variety of ways by a variety of individuals. Hasn’t it been that way ever since Eden?
