One of Cardinal Ratzinger's most important and widely read books, this volume is a revised second edition with an improved translation and an in-depth 20 page preface by the Cardinal. As he states in the preface, since this book was first published over 30 years ago, many changes and significant events have occurred in the world, and in the Church. But even so, he says he is firmly convinced that his fundamental approach in this book is still very timely and crucial for the spiritual needs of modern man. That approach puts the question of God and the question about Christ in the very center, which leads to a "narrative Christology" and demonstrates that the place for faith is in the Church.

Ratzinger's profound treatment of Christianity's basic truths combines a spiritual outlook with a deep knowledge of Scripture and the history of theology.
