With so many Catholics in the United States being under forty, this timely book asks the question, “How can Catholics in the United States respond to the challenges of ministering to young adults?” Using sociological data, the author looks at the state of the Church today, then considers five key areas of concern: theology, ecumenism, liturgy, spirituality, and moral authority. The book offers reflections on some of the challenges facing the Church in these areas, and offers constructive suggestions for how Catholics—including laity and clergy—can respond to them by better understanding the world that young adults inhabit. Fascinating, productive, and hopeful, this book will be important reading for anyone concerned with the future of the Church. †
