Dr. Stephen Bullivant is Senior Lecturer in Theology and Ethics at St Mary’s University, England. A former atheist, he studied philosophy and theology at Oxford University, and converted to Catholicism while completing his doctorate on Vatican II and the salvation of unbelievers. In 2010, he was the first non-American to receive the “LaCugna Award for New Scholars” from the Catholic Theological Society of America. Stephen writes and speaks extensively on the theology and sociology of atheism, and the new evangelization. His recent books include Faith and Unbelief (Canterbury Press, 2013; Paulist Press, 2014), and (co-edited with Michael Ruse) The Oxford Handbook of Atheism (Oxford University Press, 2013). His latest book is called The Trinity: How Not to Be a Heretic (Paulist Press, 2015).
