This book makes a certain demand on its readers, though perhaps less on the professional theologian au fait with current research than on the layperson, for whom it is equally designed. The reader will look in vain here for much that from the beginning has been a familiar part of the church's tradition, deriving above all from the Book of Acts. The reasons for this slight, and critical, use of Acts are give in the Introduction. In the matter of Paul's own epistles, too, this book often goes ways of its own. If we are to think Paul's theology along with him and follow it, we certainly need to prepare ourselves and to persevere. At the same time, with a thinker of Paul's stature, it is impossible to make him seem easier than he is. Bornkamm has tried not only to give some account of his life and thought but also to let the reader share in the process of questioning and discovery.In Paul's theology many topics and ideas are so interrelated that the reader should not in every case expect exhaustive treatment of a particular subject under the relevant heading. For more detailed discussion he must refer to other related ideas and key words.
