Prof D. Densil Morgan BA, BD, DD (Wales), DPhil (Oxon), FLSW

Emeritus Professor

Before being appointed Professor of Theology at University of Wales Trinity Saint David in 2010, I spent twenty two years at Bangor University, North Wales, where I was successively lecturer, senior lecturer, reader and professor. During that time I spent sabbatical terms in both Princeton and Oxford. I was British Academy Visiting Scholar at Princeton Theological Seminary in 2001, Visiting Scholar at Regent’s Park College, Oxford, in 2008, and during the same year was appointed member of the Center for Theological Inquiry at Princeton. In 2005 I was awarded the DD degree by the University of Wales on the basis of my published works. I was made Fellow of the Learned Society of Wales in 2011 and was honoured by the Gorsedd of Bards by being appointed member in 2012.

1. The History of Theology in Wales

My first book (1991) was on the eighteenth and early nineteenth century Baptist preacher Christmas Evans, and having spent much of the 1990s and early 2000s doing work on twentieth century themes both in Wales and beyond, I returned to the study of the Welsh religious tradition. Among my publications was a volume on the nineteenth century Welsh-American theologian R. S. Thomas (2005), a volume entitled Wales and the Word: Historical Perspectives on Welsh Identity and Religion (2008), a critical biography of the principal Welsh theologian of the Victorian era, Lewis Edwards (2009), an assessment of the life and work of the Methodist preacher Edward Matthews (2012), a chapter on Welsh preaching between 1689 and 1901 in The Oxford Handbook of the Sermon (2012), an analysis of the development of doctrine among the Calvinistic Methodists in The History of Welsh Calvinistic Methodism (2013), and a chapter entitled ‘Nonconformity in Wales’ in The T & T Clark Companion to Nonconformity (2013). An edited volume on Thomas Charles of Bala was published in 2014 while a chapter entitled ‘the Bible and vernacular culture’ is due to appear in a composite volume The People’s Book: Reformation and the Bible in 2017. The first volume (1588-1760) of a two-volume history of Welsh theology Theologia Cambrensis: A History of Protestant Theology in Wales is in preparation, and is scheduled for publication in 2018.

2. The Barthian Theology and its Reception

The Swiss theologian Karl Barth (1886-1968) is generally regarded as the greatest Protestant theologian of the modern age. An absorbing interest in his work since student days led to an analysis of his multi-volumed Church Dogmatics in the volume Barth (1992) and an assessment of his impact on Welsh religion via his disciple, J. E. Daniel (1993). The reception of Barth’s work became an aspect of two volumes published in 1999 and 2001, namely The Span of the Cross: Christian Religion and Society in Wales, 1914-2000 and its companion, Cedyrn Canrif: Crefydd a Chymdeithas yng Nghymru’r Ugeinfed Ganrif. My own doctrinal standpoint was heavily influenced by Barth’s theology as seen in the volume The Humble God (2005). Membership of the Center for Theological Inquiry at Princeton in 2008 led to a fresh analysis of the Church Dogmatics in The SPCK Introduction to Karl Barth (2010) and a detailed study of his influence on religion in the UK in Barth Reception in Britain (2010, 2^nd ed. 2012). Further research will centre on the contribution of Barth’s English disciples, especially those linked with Congregationalism’s ‘New Genevans’ of the 1940s and 1950s. 

3. The Theology of Culture

A third strand of my work has been on the interface between history, theology and creative literature especially twentieth century poetry in Wales. I co-operated with the Anglican scholar A. M Allchin to produce Sensuous Glory: the Poetic Vision of D.Gwenallt Jones (2000) while a study of Pennar Davies (1911-96), theologian, novelist, poet and all-round polymath appeared in 2002. Other publications on these themes have included  ‘Incarnate glory: the spirituality of D.Gwenallt Jones (1899-1968)’, in Celts and Christians: new approaches to the religious traditions of Britain and Ireland (2002), ‘Celts and Christians in the work of Pennar Davies’, in Respecting the Past and Shaping the Future: Festschrift for Gareth Lloyd Jones (2003), and ‘Spirit and flesh in twentieth century Welsh poetry: a comparison of the work of D Gwenallt Jones and Pennar Davies’, in Christianity and Literature (2007). A critical introduction to a new edition of Saunders Lewis’ classic study Williams Pantycelyn appeared in 2016.
