Contact Details


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; 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. 

Ordained to the Order of Ministry of the United Church of Canada since 1996, I am an elder of the cathedral Church of St Machar, in Old Aberdeen.

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

Research Areas

Research Overview

My research interests include 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. I am also active in exploring the significance of recent work on New Testament apocalyptic for contemporary Christian theology. 


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 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 welcome enquires from potential PhD research students, particularly those looking to pursue their studies on-campus here in Aberdeen. We have a limited number of places each year for new research students in the Systematic Theology area and admission is necessarily selective.

Research Funding and Grants

In the autumn of 2018 I was 'Research in Residence' in the Theology Department of the Free University of Amsterdam.

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.
