The writer believes that the centuries of fluid religious thought that preceded the violent ultimate crystallisation of Nicaea, was essentially a struggleobscured, of course, by many complexitiesto reconcile and get into a relationship these two separate main series of God-ideas.
Putting the leading idea of this book very roughly, these two antagonistic typical conceptions of God may be best contrasted by speaking of one of them as God-as-Nature or the Creator, and of the other as God-as-Christ or the Redeemer. One is the great Outward God; the other is the Inmost God. The first idea was perhaps developed most highly and completely in the God of Spinoza. It is a conception of God tending to pantheism, to an idea of a comprehensive God as ruling with justice rather than affection, to a conception of aloofness and awestriking worshipfulness. The second idea, which is opposed to this idea of an absolute God, is the God of the human heart.
