In this timely book, McFague recalls her readers to the practices of restraint. In a world bent on consumption it is imperative that people of religious faith realize the significant role they play in advocating for the earth, and a more humane life for all. The root of restraint, she argues, rests in the ancient Christian notion of kenosis, or self-emptying. By introducing kenosis through the life stories of John Woolman, Simone Weil, and Dorothy Day, McFague brings a powerful theological concept to bear in a winsome and readable way.
