Holiness is a challenge for contemporary Jewish thought. The concept of holiness is crucial to religious discourse in general and to Jewish discourse in particular. "Holiness" seems to express an important feature of religious thought and of religious ways of life. Yet the concept is ill defined. This collection explores what concepts of holiness were operative in different periods of Jewish history and bodies of Jewish literature and offers preliminary reflections on their theological and philosophical import today. The contributors illumine some of the major episodes concerning holiness in the history of the development in the Jewish tradition. They are challenged to think about the problems and potential implicit in Judaic concepts of holiness, to make them explicit, and to try to retrieve the concepts for contemporary theological and philosophical reflection. Not all of the contributors push into philosophical and theological territory, but they all provide resources for the reader to do so. Holiness is elusive but it need not be opaque. This volume makes Jewish concepts of holiness lucid, accessible, and intellectually engaging.

According to the account in the Book of Exodus, God addresses the children of Israel as they stand before Mt. Sinai with the words, "You shall be to me a kingdom of priests and a holy nation" (19:6). The sentence, Martha Himmelfarb observes, is paradoxical, for priests are by definition a minority, yet the meaning in context is clear: the entire people is holy. The words also point to some significant tensions in the biblical understanding of the people of Israel. If the entire people is holy, why does it need priests? If membership in both people and priesthood is a matter not of merit but of birth, how can either the people or its priests hope to be holy? How can one reconcile the distance between the honor due the priest and the actual behavior of some who filled the role? What can the people do to make itself truly a kingdom of priests? Himmelfarb argues that these questions become central in Second Temple Judaism. She considers a range of texts from this period, including the Book of Watchers , the Book of Jubilees , legal documents from the Dead Sea Scrolls, the writings of Philo of Alexandria, and the Book of Revelation of the New Testament, and goes on to explore rabbinic Judaism's emphasis on descent as the primary criterion for inclusion among the chosen people of Israel—a position, she contends, that took on new force in reaction to early Christian disparagement of the idea that mere descent from Abraham was sufficient for salvation.
