He reframes religion (specifically Christianity and the Bible) as a symbolic guide to living as opposed to a historical text that should be taken at face value. i.e. God is a symbol for the greatest good. Christ is a symbol for the human ideal of that greatest good.

In his view, the value of the Bible is not as a pre-scientific historical account of the world. Instead, it's a survival guide for generations of people (who had no concept of science anyway) told in story form.

When I look at his religious metaphors in that light, they seem relevant and meaningful in the context of his 12 Rules.
