My Personal Webpage



Previously educated at the Royal Military College of Canada and the University of Toronto, I earned a doctorate from the University of Toronto / Victoria University, where I studied systematic and historical theology, ecumenics, and the philosophy of religion at several member colleges of the Toronto School of Theology, where during my final year I was also a Junior Fellow of Massey College. After holding a Postdoctoral Research Fellowship at Princeton University's Center for the Study of Religion, I taught for several years at the Atlantic School of Theology in Halifax, Canada as Assistant Professor of Systematic Theology. I joined the faculty of the University of Aberdeen as Lecturer in Systematic Theology in January 2006. In 2016 I was appointed to a personal chair as Professor in Christian Dogmatics. 

I was ordained to the Order of Ministry of the United Church of Canada in 1996.

I am a Senior Fellow of the UK Higher Education Academy.


Research Interests

My research interests include contemporary Christian dogmatics with particular interest in Christology; the doctrines of justification, election and revelation; the Christian life and the theological bases of Christian ethics and politics; as well as the history of modern Protestant theology generally, and within it particularly the theologies of Søren Kierkegaard, Dietrich Bonhoeffer and Karl Barth. The latter two are interests shared with a number of my colleagues here in Aberdeen. I am also much involved in explorations of the significance of New Testament apocalyptic for contemporary Christian theology. 

I welcome inquires from potential PhD research students, particularly those looking to pursue their studies on-campus here in Aberdeen. For general information about PhD study with us in Divinity here at the Unviersity of Aberdeen follow this link.

Current Research

I am currently writing on topics including the theology of the Confessing Church; the contemporary signification of Bonhoeffer's Ethics; Karl Barth's account of the Devil; epistemic questions involved in N.T. Wright's recent Gifford Lectures (History and Eschatology); Kierkegaard's concept of works of love in conversation with recent work by John Barclay on Paul and the Gift;and, thinking together with colleagues about a project on the fate of the devil in modern theology, both Protestant and Catholic.

At the moment I am also involved editing the volume of the Edinburgh Critical History of Christian Theology treating the 20th century; working with R. David Nelson to oversee a substantive new Handbook of Modern Theology for T&T Clark, and editing, together with Kait Dugan, a volume of papers exploring eschatological aspects of Karl Barth's Theology under the title The Finality of the Gospel .


I am Editor-in-Chief of Brill Research Perspectives in Theological Traditions.

Together with Ian MacFarland and Ivor Davidson, I edit the T&T Clark Studies in Systematic Theology series.

Together with Jenny McBride and Michael Mawson, I edit the forthcoming series, New Studies in Bonhoeffer's Theology and Ethics.

I am an Associate Editor of the Journal of Reformed Theology.

I collaborate with Douglas Harink in the leadership of a working group, 'Explorations in Theology and Apocalyptic' investigating the contemporary relevance of New Testament apocalyptic modes of discourse for the work of Christian dogmatics and ethics. Once again this year we will be hosting several sessions during the annual meeting of the AAR/SBL in November.

Research Grants

In 2016/17 I held the Alan Richardson Fellowship at Durham University which I used to advance work on a project exploring modern philosophical critiques of Christian faith and theology.

From 2013-2017 I was lead academic on an interdisciplinary research project entitled 'Normativity: Nature, Narrative and Nihilism' supported by the College of Arts and Social Sciences and involving colleagues from theology, theological ethics, philosophy and law exploring the sources and nature of 'Normativity' in our respective fields of study.

From 2014-2106 I was Principal Investigator on a collaborative project entitled 'Eternal God, Eternal Life: Theological Explorations into the Concept of Immortality'  funded by the Templeton Foundation as part of their larger Immortality Project led by John Martin Fischer from the University of California, Riverside.  We hosted a series of workshops and a final conference in Aberdeen on the theme during 2014/15 and have together authored a book on the theme (T&T Clark/Bloomsbury, 2016), details of which can be found here.
