This collection of essays on John Owen's theology, serving as testimony to a general surge of interest in the seventeenth-century Puritan divine's thought in recent years, evolved from a conference on Owen held at Cambridge University in 2008. The volume possesses few of the shortcomings that commonly characterise collections of essays stemming from conference proceedings, much to the credit of the editors who very obviously maintained high standards of scholarship for submissions and, by their own admission (p. xvii), made the hard but ultimately correct decision to exclude some papers from that conference and solicit some new chapters for this publication. The result is seventeen high-quality essays complemented by a rather thorough Owen bibliography compiled by John Tweeddale and a very helpful preface by Carl Trueman which situates recent Owen research on the map of trends in the study of post-Reformation Reformed theology more broadly. The volume includes essays exploring Owen's take on many of the traditional and expected theological loci, for example, Trinity (Robert Letham), Pneumatology (Kelly Kapic), Christology (Alan Spence), and justification vis-à-vis union with Christ (George Hunsinger). Suzanne McDonald's essay on an aspect of Owen's thought which might be less expected in the realm of early modern Protestant theology, his doctrine of the beatific vision, stands out as one of the most intriguing and illuminating contributions. While much praise is due to this book, a question might be raised about how well it fulfils the role of an actual research companion (in a series of works intended ‘to offer scholars and graduate students a comprehensive and authoritative state-of-the-art review of current research in a particular area’). Quite a number of aspects of Owen's theology remain untouched and unexplored. Moreover, a number of essays explore subjects related tangentially at best to Owen's theology per se, for example Tim Cooper's analysis of Owen's personality, or Crawford Gibben's consideration of whether the auction catalogue of the content of Owen's library (the Bibliotheca Oweniana; 1684) supports scholarly depictions of Owen as a ‘Renaissance man’. The division of the book into three overarching sections respectively titled ‘Method’, ‘Theology’ and ‘Practise’, does little to alleviate this slight concern about the book's focus since neither the meaning of the section titles nor the rationale for including certain essays in specific sections is immediately obvious; Gert van den Brink's piece on the impetration and application of salvation in Owen's thought, filed under ‘Method’, is as solidly theological as they come. There is, however, no question but that the essays actually included in this volume, whatever the logic of their inclusion or categorisation, are of the highest scholarly quality. This book should be declared required reading for students and scholars of Owen's thought and/or post-Reformation Reformed theology more broadly, in a British context and beyond.
