During a 1980s Edmonton Oilers game, fans unveiled a banner claiming, On the 8th day, God created Gretzky. Intersections between religious belief and sporting participation are nothing new, where players, coaches, and fans are known to pray, cross themselves, and point to the heavens during a game. But what should be the relationship between sports and religious faith? On the Eighth Day introduces the theology of sport from a Catholic standpoint. It wrestles with sport’s universal appeal, its rich symbolism, and its spiritual and moral characteristics. Sport is a place where embodied games can be sacramental; where traditions of the past speak to contemporary peoples; and where truth and justice are demanded in a world affected by sin. The eighth day recalls the playful, re-creative work of God the Creator embodied in Christ’s resurrection. In this sense, this book marks out a new day in Christian attitudes toward modern sport and the continuing call to redeem sport in service of human flourishing. Comprehensive yet accessible, the book will engage thoughtful lay sports fans and academic students alike.
