A Sukkah in the Shadow of Saint Ignatius is a trio of essays commemorating the 2017 and 2018 University of San Francisco Speaker Series in the History of Jewish-Christian Relations. The volume is a joint publication of the Joan and Ralph Lane Center for Catholic Social Thought and the Ignatian Tradition, and the Swig Program in Jewish Studies and Social Justice. The essays contained in this volume explore the two-millennium history of Jewish-Christian relations through focused investigations of central topics. Natalie Latteri (USF) examines the thorny problem of inter-religious polemic in her study of how Jews in medieval Ashkenaz recounted the infancy of Jesus of Nazareth. Ariel Evan Mayse (Stanford) surveys the variety of attitudes toward Christianity in Hasidism and Neo-Hasidism, and reflects on the potential of Neo-Hasidic theology for generating a platform of interreligious cooperation. Jeremy P. Brown (McGill) interrogates the limits of religious hospitality as an institutional mandate for hosting Jewish Studies at Christian Universities. The volume opens with a frank exchange of letters between Aaron Hahn Tapper (USF) and Erin Brigham (USF) that wrestles with the ethical, religious, and social challenges confronting the development of Jewish Studies within a Jesuit Catholic academic environment.
