In my view, notions of God ‘sanctioning’ scripture developed as a consequence of belief in ‘scripture alone’ and the inerrancy of scripture, and the culture we live in - among other things. Claims such as; ‘if it’s not in the bible, it’s something it’s not necessary to know,’ ‘if it was important God would have recorded it,’ all ‘the answer to all life’s questions can be found in the bible’ endorse this belief.
In addition, we now live in a ‘blame and claim’ culture. were taking responsibility for own actions and using your own common sense (or as my grandfather used to call it, 'uncommon sense) is greatly discouraged. I don’t know if you’ve had this experience, but I have bought tins and bottles with instructions on how to open them written on the side. The human race managed to open tins and bottles for years without instructions. In today’s climate, the manufacturer must place a written warning the side of bottles, instructing people who have taken leave of their senses opening it with one’s teeth as opposed to a bottle opener is not recommended. If they don’t, the plonker who ends up in the Accident and Emergency department of the hospital with a cut lip and missing a few molars will sue them, because ‘they weren’t told.’
The consequence of all this is an image of God has emerged, that is one of a God who spells everything out. Is that the image of God the Israelite’s had? Did the author’s believe God ‘sanctioned’ every word, and ‘ignored’ any mistakes they, or anyone else in years to come would make? Did they write it so in years to come people would be able to answer any question posed to them on an internet forum? Did God have them write it for that purpose?
How significant is the ‘sanctioning’ of every word of scripture in terms of understanding and interpreting Revelation? In the first instance, how were the words revealed? Did God require the cooperation of the authors in the compilation of scripture? Did they have a choice in writing it? Could they have refused? Did they record scripture simply out of obedience because they were told to, and every single word has God’s ‘approval’ He proof read the bible and ‘rubber stamped’ it? Take for instance the Psalms - poems, song of praise. If the above were true then God is merely writing about Himself. Take the Song of Solomon - pretty erotic stuff. What message is the author communicating in this? Is it a book of ‘commands?’ Did God ‘sanction’ every word?
The bible is not a book of commands. Historical events are recorded from the perspective of the author - not for purpose of telling us God approved of everything the Israelite’s did, that is not the author’s intention. The Israelite’s weren’t the nicest, kindest bunch of people you could have met, and it should not be assumed everything they did had God’s approval because it is recorded in the bible. We can say that sometimes the author’s of the OT believe God approves of the actions of the Israelite’s, which has to do with their image of God - but sometimes they don’t. It is a record of the human experience of God, a growing in understanding of Revelation, the struggles of a nation to live in accordance with Divine Law, and the belief that God does not cast people of because he does not approve of their actions, but rather desires they return to him, restores them, and they have greater understanding of who God is as a consequence.
