Including contributions from twenty-two leading moral theologians, this volume is the most thorough assessment of modern Roman Catholic social teaching available. In addition to interrogations of the major documents, it provides insight into the biblical and philosophical foundations of Catholic social teaching, addresses the doctrinal issues that arise in such a context, and explores the social thought leading up to the "modern" era, which is generally accepted as beginning in 1891 with the publication of Pope Leo XIII’s Rerum Novarum. The book also includes a review of how Catholic social teaching has been received in the United States and offers an informed look at the shortcomings and questions that future generations must address. This second edition includes revised and updated essays as well as two new commentaries: one on Pope Benedict XVI’s encyclical Caritas in Veritate and one on Pope Francis’s encyclical Laudato Si’. An outstanding reference work for anyone interested in studying and understanding the key documents that make up the central corpus of modern Catholic social teaching.
