That They Be One

A comprehensive historical study of the complete content and overall coherence of two and a half centuries of papal instructions that have variously aroused worldwide interest, scorn, fury, reaction, and consent. It provides the kind of analysis that concerned Roman Catholics, public officials, social ethicists, theologians, and students need. It is a textually inclusive and topically broad-gauged review of Catholic social teaching in its historical development, with a forthright assessment of its regrettable contradictions as well as of its valuable consistencies.
