Slowly the American estimate of Karl Barth is changing as more and more of his work is translated into English, and he is soon as a contemporary theologian, coping with the impact of the times upon the Word of God. This book is one more step in giving Americans an accurate approach to one of the greatest 20th century theologians. The author is a student of Karl Barth, and one admitted to the closer seminar group that studied him well and know him personally. It reflects his first-hand knowledge and his enthusiasm. Even more, the volume was reviewed in its entirety by Karl Barth before the German edition was published, and commended by him in a signed Preface for summarizing well what he was trying to say. In addition, Georges Casalis' presentation has been made all the more valuable by the long supplementary introduction by Robert McAfee Brown. Very helpful to the man unaware of the prodigious output of Karl Barth is the summary of his principal writings. One feature of Casalis' work is his return again and again to the kind of person his ment is. The power of Barth is not because he has written a modern, Protestant ""Summa"", but rather, that he has wrestled text by text with the Word of God, and that he never forgets that the Word must be personally proclaimed and personally heard. To believe this requires a sense of humor on Barth's part, and this extra quality of the man also shines clearly through this volume. No preacher, theologian nor philosopher dares to ignore this book so tenderly written about one of the world's great thinkers by a student who loves him.
