This accessible introduction covers the complete history and contemporary contexts of the church's involvement in Catholic social tradition, giving distinctive attention to the Bible, liturgy, the thought of Augustine and Aquinas, and recent theological developments. Bringing together veteran teachers of Catholic Social Teaching who have worked together on the content, this book is designed to set social questions within the Catholic tradition and contemporary life. End-of-chapter application sections address practical concerns, such as racism in the church, charity, consumerism, and talking with neighbors and coworkers about moral issues. Discussion questions, case studies, excerpts of church documents, and suggestions for further reading enhance the book's usefulness. It will work well for students of theology and ethics, particularly Catholics but also Protestants who want to know more about the Catholic social tradition.
