It is true that men rejected God and made humanity God, but before that man made the Inward God a God, or they defined the Father-Within as God, and man rejected, or left undiscovered, the natural Godhood reached in material evolution. The church was still needed to mediate between the God Within and humanity, but then virtually all forms of God were rejected and the church was not needed at all.
Either way, whether it is man without God, or man with the God Within man, it is the self-divination of man that is the problem. The Inward Path to the God Within man tends to be satisfied with the bliss of experiencing the God Within, and modern man without God tends to think only of improving divine man, the species, and not surpassing man and evolving to new and better species. Both are man-made blockades against evolving to real Godhood.
Man needs to be seen not as divine, and not only with divinity within man, man needs to be seen as evolving toward real Godhood in the cosmos. The Evolutionary Outward Path of material and supermaterial evolution to Godhood needs to supersede, but not replace, the concept of man himself as divine, as well as superseding but not replacing the Involuntary Inward Path to the God Within.
