Noted liturgical and sacramental theologian Kevin W. Irwin expertly analyzes and summarizes the salient teachings of the Catholic magisterium on the sacraments of the eucharist and orders and offers ideas on ways to apply these teachings for the future. Alternating highly technical summaries with reflective essays based on them, Irwin maintains an awareness that not all magisterial documents carry the same theological weight, and his insightful commentary consistently reflects and respects the distinctions among the various ranks of documents. This book is updated with documents issued since the first edition's release in 2013, notably Pope Francis's Laudato Si' and Amoris Laetitia. Book jacket.
