As a result of the Second Vatican Council, many people are more actively interested in questions about the Christian faith, and in particular about Catholic teaching. New questions are being asked, old questions are being repeated, and at times the old answers seem no answer at all. If we were to change too many answers, we would change Christianity too, in order to supply the answers we want-the ones we would like to be true. This book seeks to present a synthetic view of Christian doctrine which takes into account the honest needs behind this modern questioning.
