"In his essays, Leibowitz produced sharp and thought-provoking insights on many subjects such as the nature of holiness, chosenness, Messianism, prayer, redemption, and general and personal providence. His consistent and provocative thought gave him a prominent position in contemporary Jewish thought, especially in Israel. His thinking, even when contested, is stimulating and powerful and invites or even forces people to respond by formulating their own views."
