Book excerpt: Discovered in the rubble of the Warsaw Ghetto, Rabbi Kalonymus Kalmish Shapira's wartime writings exemplify the faith of Hasidic Jewry under the unimaginable conditions of the Nazi occupation. Published in 1960 under the Hebrew title Aish Kodesh, the notes of Rabbi Shapira's weekly Sabbath sermons and annotations have been studied by pious Hasidim and secular academics alike, seeking his answers to the searing theological questions posed by the war. Why do the righteous suffer? Where was God during the Holocaust? Torah from the Years of Wrath provides a new and essential scholarly contribution by placing Rabbi Shapira's writings in their immediate historical context.
