In Germany they came first for the Communist, and I didn't speak up because I wasn't a Communist. Then they came for the Jews, and I didn't speak up because I wasn't a Jew. Then they came for the trade unionists, and I didn't speak up because I wasn't a trade unionist. Then they came for the Catholics, and I didn't speak up because I was a Protestant. Then they came for me, and by that time no one was left to speak up.
What should we do? We have no wish to interrupt the destroyer's work of saving lives... But war is war and the people being picked up out of the water are soldiers bound for the front; soldiers who are to shoot at our German brothers... The question whether we are to perish in despair or defiance, or survive all trails with a live conscience, depends wholly and solely on whether we believe in the forgiveness of sins. This 25th January was the turning point in my life, because it opened my eyes to the utter impossibility of a moral universe.
