This presentation examines the development of Jewish-Christian dialogue and its adaptation to contemporary theological challenges. In the latter half of the 20th century, the dialogue between these two faiths was largely shaped by the historical necessity of addressing the aftermath of the World Wars and the Holocaust. These events spurred a critical reexamination of foundational texts, prompted reflection on core beliefs within each tradition, and encouraged a rethinking of stereotypes regarding the meaning and potential of the encounter between Judaism and Christianity. This dialogue revealed that interfaith engagement not only fosters mutual understanding but also deepens the internal theological and moral discourse within each religion. Today, this dialogue faces a new set of challenges, particularly the urgent global issues of sustainability and technological advancements. These challenges call for a renewed and expanded interreligious conversation. How can Jewish and Christian theological frameworks contribute to the ethical imperatives of sustainability and the responsible integration of technology into human life?This presentation will explore how a critical and collaborative approach to these issues, rooted in the history of dialogue and reinterpretation, can redefine the responsibilities and roles of religious traditions in addressing the pressing global challenges of our time.
