This is a theological interpretation of Judaism focusing on the Jewish covenantal obligation to offer Judaism and welcome converts. The term "Jewish universalism" is applied to the theory because the central idea of the interpretation is that Judaism is a universal religion. This is supported by an analysis of the basic theological concepts of Judaism (God, the natural world, humanity, chosenness, revelation, covenant, mission, the nation of Israel, and redemption). These concepts are understood to emphasize the Jewish mandate to offer Judaism without requiring it. It includes other arguments for welcoming converts besides Jewish universalism and how these arguments are related. This book is an original synthesis of current scholarship, and provides a detailed, systematic theological interpretation of covenantal obligation.
