This lecture deals with the interreligious dialogue in the writings of Rabbi Moshe David Valle. Valle showed a keen interest in Catholic Christianity. By adopting an 'anthropological lens,' he addresses various aspects of Christianity: rituals, architecture, clothing, and food, seeking to elucidate them from a Kabbalistic perspective. In my lecture, I attempt to understand this somewhat bizarre endeavor as an early example of 'reverse anthropology'—an anthropological approach that examines indigenous perspectives on Western culture from the indigenous viewpoint.
