How far have we come putting into practice what was declared in the Universal Declaration of Human Rights, which this year marks its 70th anniversary? How can the Church respond today to the new challenges threatening these rights, whether relativism, fundamentalism, and persecution or new types of poverty and oppression? And with whom can the Church engage on these issues? With states, religious leaders, international institutions, cultural institutions, or first and foremost with global civil society? In addition, what are the roots of fundamental rights, and what response can there be to the danger of a multiplication of rights that can paradoxically threaten concepts on the rule of law and human dignity? These are the fundamental questions addressed and debated by the prestigious international experts whose essays appear in this book. Among them are Giuseppe Dalla Torre (Libera Università Maria Ss. Assunta), Jean Louis Ska (Pontificio Istituto Biblico), Robert P. George (Princeton University), Marta Cartabia (president of the Italian Constitutional Court), Carlos I. Massini-Correas (Mendoza, Argentina), Barbara Zehnpfennig (Universität Passau), Mary Ann Glendon (Harvard University), Joseph Halevi H. Weiler (New York University), and Roberto Baratta (Macerata, Italia). The volume also contains an essay by Cardinal Pietro Parolin, secretary of state, on "The Church's Dialogue Partners in the Discussion and Defense of Human Rights."
