How did Roman Catholicism and its beliefs and practices come to be what they are? This lively and readable account provides an up-to-date introduction, explaining what is distinctively Catholic while remaining sensitive to other Christians and other religions. The authors move through history to sum up the present characteristics of Catholic Christianity and the major tests it faces in the third millennium. Explaining matters in a fresh and original way, they do justice to the Catholic heritage and show that Catholicism is a dynamic and living faith. Well-structured, highly informative, and clearly written, the book does not duck critical issues -- such as the ministry of women and dialogue with other religions -- or the negative side of history. Rather, O'Collins and Farrugia explore the challenges facing Catholics and other Christians and engage with contemporary moral issues. This is an authoritative and accessible introduction to Catholicism for the modern reader.
