It is a dogma of the Roman Church that the existence of God can be proved by natural reason. Now this dogma would make it impossible for me to be a Roman Catholic. If I thought of God as another being like myself, outside myself, only infinitely more powerful, then I would regard it as my duty to defy him.
I think one of the things you and I have to learn is that we have to live without the consolation of belonging to a Church.... Of one thing I am certain. The religion of the future will have to be extremely ascetic, and by that I don't mean just going without food and drink.
