Chapter 10 shows how what began with philosophy’s rendering God superfluous ended in a war against the God of Abraham. Here we have the singularity of the Holocaust, which lies in a singular assault on the Jewish people as the perennial witnesses to that God the God of Abraham. Drawing on the testimony of the Holocaust diaries, written within the whirlwind of the assault on God, this chapter demonstrates that this defining feature of the Holocaust can be seen, for example, in the Nazis’ use of the holy calendar in the execution of their actions, in the prohibitions against prayer and Sabbath observance, in the destruction of synagogues and Hebrew Bibles, and in the targeting of children, elders, and mothers. What the diaries reveal about the essence of Holocaust that the historians cannot, it is argued, is this: The Holocaust was the systematic annihilation of not just of the bodies but of the souls of the Jews as a means of annihilating the God of the Jews. It is unprecedented and unparalleled.
