"There is nothing further from the christian faith than fanaticism — that
unholy alliance of the sacred and the profane, whatever guise it takes.
That danger just does not exist if we understand our struggle as Christ
has taught us to: as a war each of us makes on himself. It is a
constantly renewed effort to love God better, to root out selfishness,
to serve all men. Turning your back on this conflict, no matter what the
excuse, means surrendering before you have begun to fight. Anyone who
does so is brought low, without faith, depressed in his heart, blown
this way and that by miserable pleasures."
