“The sickness of the world is due less to a dearth of new ideas than to the rejection of old truths.” so wrote Archbishop Fulton J. Sheen in the introduction to this treasure of a book, adding, “And among old truths, none has had more disastrous consequences than the abandonment of the true nature of man.” In her penetrating exploration of Catholic Social Teaching, Sr. Mary Consilia O’Brien, O.P., Ph.D., offers the most clear-eyed description ever written on this foundational subject. She explores the Church’s authentic teachings on the dignity of the human person as well as man’s freedoms and obligation to society. She describes when individual liberties must transcend social control–and when they must not. Notably, she also explains the final purpose of society, to which all its activities must be oriented. Skillfully crafted to appeal to both students and adults, each chapter probes a topic with practical examples, excerpts from the writings of St. Thomas Aquinas, quotes from encyclicals, discussion questions, and additional study resources.
