Alan P. F. Sell, of the University of Wales Trinity Saint David and the University of Chester, is a philosopher-theologian and ecumenist with strong interests in the history of Christian thought in general, and of the Reformed and Dissenting traditions in particular. A minister of The United Reformed Church, he has held rural and urban pastorates, has served from Geneva as Theological Secretary of the World Alliance (now Communion) of Reformed Churches, and has held academic posts in England, Canada, and Wales. He has earned the rarely-awarded senior doctorates, DD and DLitt, is a Fellow of the Society of Antiquaries of London and of the Royal Historical Society, and holds honorary doctorates from the USA, Hungary, Canada, and Romania. He is the author of more than thirty books, and the editor of others. Ever seeking to hold together what belongs together, he explores the relations between philosophy, theology and apologetics, Christian ethics and moral philosophy, and doctrine in relation to spirituality and the ecumenical quest.
