Does Morality Change? examines the subject of morality and conscience, and discusses how the basic moral tenets do not change from one generation to the other, although interpretation of moral matters changes in light of new science and medical knowledge and social developments. In Does Morality Change? Father Fagan reflects on the changes that have radically altered our world and examines how they affect our understanding of morality. He points out that although it is taken for granted that morality does not change -- what is right must always be right, what is wrong is always wrong -- this is an over-simplification. Morality is based on reality, but reality itself changes, and our understanding of reality likewise changes. Father Fagan further maintains that the "moral norms" formulated by tradition are based on "reality" as experienced, understood, and interpreted by people, in light of their culture. In addition, the Catholic Church has also experienced radical changes in its understanding of itself and of the world. Within moral theology there are new methods and approaches in discussing moral issues. Before Vatican II Catholic teaching was clear and unambiguous. But the changes brought about by Vatican II have raised questions for many and confusion for some. The pastoral aim of this book is to help readers find their way in the confusion by considering some of the implications and effects of changes, and to take a fresh look at some traditional topics in moral theology.
