‘This book is a critical introduction to political theology, not an enthusiastic initiation into it’ (p 37). Such was the intention of Alfredo Fierro in making his own sizeable contribution to the subject. Drawing together a great variety of sources he tries to sketch the development of ‘political theology’, and suggests some directions for the future. This not without a sense of his own relative position: from the outset he states that ‘this book was written in Madrid, Spain, and finished in the summer of 1974 (xii). (The Militant Gospel, SCM Press 1977 xv + pp. 453 £4.50).

The book divides into three parts, Situation, Programme and Theory, eight chapters in all. In the first part, changes in the climate of thinking are described which have brought political theology into being; the second goes through the formulation of the new theology; while the third reflects on the significance of it and challenges the presuppositions of several authors.

First, though, some general comments about method. The term ‘political theology’ is used rather too frequently—I’ve already used it twice—and moreover as if one was always clear what is meant by it. Then, related to this, is Fierro’s tendency to put together several ideas about a concept without contrasting them very accurately or stating a clear view of his own. Often this makes no difference, and one appreciates the breadth of reference; but there are times when some distinctions have to be made (notably the discussion of ideology, pp 243-7), and a failure to do so is unhelpful.
