"Humanity, created by God in all its grandeur, is today facing a pivotal choice: either to construct a new Tower of Babel or to build the city in which God and humanity dwell together. Each generation inherits the task of shaping its own era, of guiding history to become a place where the dignity of every person is safeguarded, justice is promoted and fraternity is made possible." Thus begins the first encyclical of the first pope from the United States, written during the country's 250th anniversary and addressing a topic - artificial intelligence - whose industry is centered in the United States. Yet Pope Leo's message is for everyone of good will throughout the world, to remind them of the principles of Catholic social teaching, the grandeur of being human, and the dignity of work as signposts in navigating the challenges and opportunities of an economy shaped by AI. This handsome paperback version from The Catholic University of America Press, the publishers of the pope's doctoral thesis, will spark reflection and action upon Pope Leo's words.

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.

As gay men and lesbian women increasingly gained recognition and acceptance in twentieth-century literature and film, and subsequently in social and political movements, the Catholic Church reacted by subtly moving away from its overt condemnation of homosexuality as an urgent moral problem and toward tacitly shunning homosexuality as an “unspeakable vice.” In this revealing history, Francesco Torchiani reconstructs the Catholic Church’s shifting attitudes toward homosexuality during this period by drawing on a vast array of internal documents and external accounts. This monograph expands the scholarship on the relationship between Catholicism and homosexuality in terms of both method and content, ultimately concluding that the Catholic Church continues to wholeheartedly condemn homosexuality despite making genuine efforts to reflect on and understand its social and cultural impact. The Unspeakable Vice therefore sheds new light on and places into historical perspective the questions the Catholic Church continues to reckon with regarding its role in contemporary society.
