This doctoral thesis from the University of Lund provides more than a specific account of the "Oxford Group Revivalism" in Northern Europe. It also aims at an assessment of this particular movement as compared to other similar revivalist movements, notably those in Scandinavia in the 19th century. The author has set up a very ambitious project, an impression amply confirmed by his bibliography, and in his introduction where Jarlert defines the scope of his material. He is determined to do justice to the complex, international and contemporary character of the Oxford Group, by examining its "vision and strategy, doctrine and theology, mentality and function". Moreover the author has researched a remarkably wide range of sources, reflecting the specific features of this revivalist movement. He has examined not only printed and unprinted literature, but also conducted numerous personal interviews. It is no wonder that he is therefore able to provide many new insights. In particular he sheds light on the history of the Oxford Group's activities in Sweden, which is an important supplement to previous investigations, since, strangely enough, Swedish developments have been left aside, while attention has been directed towards the corresponding (though slightly differing) developments in Norway and Denmark. No less interesting is his analysis of the Oxford Group's involvement during the Nazi period in Germany. He is certainly aware of the more or less spectacular attempts, undertaken by the "leaders" from the international team, to convert key persons from the leadership of the Nazi Party, among them Heinrich Himmler. His intention, however, is not to indulge in sensational revelations. On the contrary, he provides a balanced, comprehensive account of this episode (especially pp 405-408). There can be no doubt that this research is important. But the length of his account - 440 pages of text - reflects a weakness, since the multitude of details threatens to dominate at the cost of the main theses. Moreover, it appears that Jarlert pays too little attention to the individual role of the undisputed leader of the Oxford Group, Frank Buchman, in particular, or to the leaders of the international team in general, considering that the analysis seeks to depict a new type of revivalist movement over against the traditional pietist and/or nationalist movements of the 19th century. Remarks of this kind, however, by no means weaken the overall impression of a solid and well-researched doctoral thesis. Jens Holger Schjorring, Aarhus Faculty of Theology, Denmark
