1986

Context: I am no mere chance pile of flesh and bone: if I were only that, I should fall into corruption and dust before your eyes. I am the embodiment of a thought of God: I am the Word made flesh: that is what holds me together standing before you in the image of God. … The Word is God. And God is within you. … In so far as you know the truth you have it from my God, who is your heavenly father and mine. He has many names and his nature is manifold. … It is by children who are wiser than their fathers, subjects who are wiser than their emperors, beggars and vagrants who are wiser than their priests, that men rise from being beasts of prey to believing in me and being saved. … By their fruits ye shall know them. Beware how you kill a thought that is new to you. For that thought may be the foundation of the kingdom of God on earth.
