„God“ is one of many different poetic expressions of the highest value in humanism, not a reality in itself. It is unavoidable, however, that in talking about the thought of a monotheistic system I use the word „God“ often, and it would be awkward to add my own qualification each time. Hence, I wish to make my position clear at the outset. If I could define my position approximately, I would call it that of a nontheistic mysticism. ― (1966a: You Shall Be as Gods. A Radical Interpretation of the Old Testament and Its Tradition, New York (Holt, Rinehart and Winston) 1966, pp. 18-9.)
