The items in a code stand to the moral law as bricks to a building. Wisdom must involve some comprehension of how the bricks are meant to be put together.

This has an immediate bearing on how we read the Bible. Not only is it insufficient to quote and requote the great commands of the Decalogue and the Sermon on the Mount. We will read the Bible seriously only when we use it to guide our thought towards a comprehensive moral viewpoint, and not merely to articulate disconnected moral claims. We must look within it not only for moral bricks, but for indications of order in which the bricks belong together. There may be some resistance to this, not only from those who suspect that it may lead to evasions of the ‘plain’ sense of the Bible’s teaching, but from those who have forebodings of a totalitarian construction which will legislate over questions where it would be better to respect the Bible’s silence. But in truth there is no alternative policy if we intend that our moral thinking should be shaped in any significant way by the Scriptures.
