In A Book of Saints, Anne Gordon tells the story of Father Maximilian Kolbe, who was a prisoner at Auschwitz in August 1941. A prisoner escaped from the camp, and in reprisal, the Nazis ordered that ten prisoners had to die by starvation. Father Kolbe offered to take the place of one of the condemned men. The Nazis kept Kolbe in the starvation bunker for two weeks and then put him to death by lethal injection on August 14, 1941.

Thirty years later a survivor of Auschwitz described the effect of Kolbe's action: "It was an enormous shock to the whole camp. We became aware that someone among us in this spiritual dark night of the soul was raising the standard of love on high. Someone unknown, like everyone else, tortured and bereft of name and social standing, went to a horrible death for the sake of someone not even related to him.

"Therefore it is not true, we cried, that humanity is cast down and trampled in the mud, overcome by oppressors, and overwhelmed by hopelessness. Thousands of prisoners were convinced the true world continued to exist and that our torturers would not be able to destroy it.

"To say that Father Kolbe died for us or for that person's family is too great a simplification. His death was the salvation of thousands. ... We were stunned by his act, which became for us a mighty explosion of light in the dark camp."
