The relationships between the Old and the New Testaments--and especially, ""the use of the Old Testament in the Church of Christ""--furnishes the ground for Professor Barr's discussion of a number of important questions of a general theological nature of current importance. He sees the use of the Old Testament as raising issues connected with more general trends in theological thinking today. Contrary to a tendency predominant in recent Old Testament theology, he does not see the events recorded in the Old Testament as the source of theological conclusions. Rather, what has been ""thought and said"" before the event provides the framework within which the events can be considered as meaningful. He stresses, therefore, the importance of what God ""has said"" as being prior to what He is reported as having done. The consequences flowing from such a shift of position can be illustrated in the author's own confession that for him, Karl Barth's theology ""has collapsed in ruins."" Material in this volume was first delivered as the Currie Lectures at Austin Presbyterian Seminary. The style retains the freshness and directness of oral communication, making the book accessible not only to students but to lay readers more generally.
