As issues of climate and ecology become ever more important, Christian communities are increasingly looking for appropriate ways to respond to the current crisis in their worship and liturgy. In this book, Mark Porter draws on more than 40 interviews with activists, song-writers, Christian leaders, and musicians to explore what it means to develop new Christian musical practices for a time of ecological crisis. Through these different conversations, the book enters into fundamental questions regarding our relationships with the world around us, the relationship between spirituality and ecology, and the different ways in which we can engage with the climate crisis which we are facing.
