This volume is the first truly global commentary on a papal encyclical. Pope Francis published Fratelli Tutti in October 2020 in the midst of interrelated global crises: climate catastrophe, ongoing racial injustice, a widening gap between the rich and the desperately poor, battles over human migration, the rise of authoritarian politics, and the erosion of democracy, all exacerbated by the COVID-19 pandemic. The encyclical provided a sobering assessment of the devastation but also a hopeful vision of solidarity and healing. The responses in this book not only reflect on Fratelli Tutti from a great diversity of locations and perspectives but also attempt to model Francis's call to fraternity and sorority within this volume. In these pages, scholars from around the world create a conversation meant to embody one of the virtues that Francis elicits in the encyclical: creative openness to the reciprocal gifts of others. This book takes up Pope Francis's invitation to continue talking, thinking, and acting, always in a climate of both confidence and audacity, to promote social friendship among the people of the world.
