Existential estrangement, e.g., arises from ultimate concern about that which is not ultimate. What ought to arouse ultimate concern is the unconditional ground of being itself. Hence concern, e.g., for a theistic God who is a personal being, but nonetheless a being alongside other beings, is not concern for being itself. The concern perpetuates estrangement because only being itself transcends all that exists as its ground, and only the concern for it that is manifested as love can bring about the new being. Said state, not priests, have authority.

Religion is good only for morality. Christianity must be tested by natural religion. Wrote Christianity as Old as the Creation . Creation is perfect, so nothing can or should be added to it. Christianity Not Mysterious .
