Joshua has taught theology and philosophy in Germany, Ireland, the UK and Ukraine and is the author of books and articles (academic and popular) on the public significance of Christian faith. Fluent in German and Russian and proficient in many European languages, he has had an active ministry in Ukraine over many years. He has co-written a book on mission in the former USSR, entitled, A Future and a Hope, and a booklet on the Ukrainian evangelical church, entitled, Church Without Walls: Post-Soviet Baptists after the Ukrainian Revolution. His most recent book, Theology After Christendom, was translated into Ukrainian in 2020.
Joshua is Director of Postgraduate Studies at Spurgeon’s College in London and serves on the Faculty of the Institute of Ecumenical Studies in Lviv, Ukraine, where he teaches a course on Ecumenical Theology. He was awarded a Fellowship in the UK Higher Education Academy and was appointed a Fellow of the Royal Historical Society in recognition of his contributions to academic historical studies. His favourite books are Thomas Mann’s Der Zauberberg (fiction) and Timothy Snyder’s Road to Unfreedom (non-fiction), which, in his opinion, offers a compelling and well-researched analysis of Ukrainian history and politics.
