This book is a systematic treatment of moral theology from the perspective of liberation theology. It not only surveys the evolution of Catholic moral theology but lays the foundations for a Christian ethic in a world of injustice. In a courageous, balanced, readable way, Moser and Leers examine moral theology-past and present-and explore liberation theology's central ethical principles. They show how moral theology led to dead ends first by the scholastic morality, and then by the renewed morality of contemporary western Europe. The first they argue failed through concentration on the object of moral actions; the second through concentration on the individual as the main subject.
