Personal Chair



Born and raised in southwestern Ontario in Canada, I was educated at the Royal Military College of Canada and the University of Toronto, before undertaking postgraduate studies in theology in Toronto studying systematic and historical theology, ecumenics, and the philosophy of religion at several member colleges of the Toronto School of Theology; during my final year of doctoral studies I was a Junior Fellow of Massey College. I graduated with my doctorate from the University of Toronto / Victoria University in 2002.

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 and currently serve as Trustee of the General Assembly of the Church of Scotland.

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

Research Overview

My research interests comprise core topics in 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. 


Research Areas

Current Research

I am currently writing on topics including: the construal of divine and human identity and the Christian life within an apocalyptic theological vision; the relation of the doctrine of scripture and the practice of Sachkritik; the motif of the 'victory of Christ' in the history of soteriology; trajectories in theology in Western Europe in the latter half of the 20th century; the contemporary significance of Bonhoeffer's Ethics; the fate of the devil as a theme in modern European theology.

I have recently edited the newest volume of the Edinburgh Critical History of Christian Theology which treats of the 20th century (EUP, 2022). Together with Kaitlyn Dugan, I've also recently edited The Finality of the Gospel: Karl Barth and the Tasks of Eschatology (Brill, 2022). At present, I am working with R. David Nelson to oversee a substantive new Handbook of Modern Theology for T&T Clark due to published in 2023.

Past Research

For a list of my research publications to date see here:




Together with Pieter Vos, I am Editor-in-Chief of The Journal of Reformed Theology .

I am Editor-in-Chief of Brill's Companions to Modern Theology series.

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 new T&T Clark New Studies in Bonhoeffer's Theology and Ethics series.

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.


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.
