This volume explores how major religious traditions engage with Pope Francis' encyclical Fratelli Tutti, offering comparative insights into fraternity, solidarity, and ethical responsibility in a global bioethical discourse. Bringing together perspectives from Christianity, Judaism, Islam, Hinduism, Buddhism, and Confucianism, the book examines how Fratelli Tutti resonates with and challenges diverse theological and moral frameworks. Contributors reflect on religious responsibility, ethical pluralism, and the prospects for interreligious solidarity amid global fragmentation. The volume offers a nuanced account of both convergence and contestation across traditions. Designed for scholars and advanced students in religious studies, theology, bioethics, and comparative ethics, this book will be of particular interest to those engaged in interfaith dialogue and global moral discourse.
