Ignaz Maybaum is one of the most well-known Jewish theologians of the 20th century. Friedrich Lotter provides insight into the tumultuous life of the rabbi and presents his main theses. This includes Maybaum's critique of Zionism, to which he opposes the concept of a conservatively enlightened Judaism in the diaspora. Another central theme for Maybaum is the relationship between Orthodox and liberal Judaism. Additionally, he addresses Christian-Jewish relations and the anchoring of Judaism in Western civilization. A crucial aspect for understanding Maybaum's thought is his early theological interpretation of the Holocaust. Lotter's explanations and comments complement Maybaum's original texts.
