No one is without Christianity, if we agree on what we mean by the word. It is every individual's individual code of behavior, by means of which he makes himself a better human being than his nature wants to be, if he followed his nature only. Whatever its symbol—cross or crescent or whatever—that symbol is man's reminder of his duty inside the human race. Its various allegories are the charts against which he measures himself and learns to know what he is. It cannot teach man to be good as the textbook teaches him mathematics. It shows him how to discover himself, evolve for himself a moral code and standard within his capacities and aspirations, by giving him a matchless example of suffering and sacrifice and the promise of hope.
