"With this impressive book, Khaled Anatolios takes his place alongside luminaries like R. P. C. Hanson and Lewis Ayres as one of the most distinguished interpreters of Nicaea and its legacy. Especially important is his sympathetic interpretation of Athanasius. For anyone who wants to understand Nicene Christianity and its relevance for today, Anatolios is quite simply indispensable."--George Hunsinger, Hazel Thompson McCord Professor of Systematic Theology, Princeton Theological Seminary"Khaled Anatolios's new book is a welcome addition to the flood of revisionary scholarship on patristic trinitarian theology in the last twenty years. Anatolios's treatment helps us to see the perennial importance of the key figures of the fourth and fifth centuries for all of our thought on this central mystery of the Christian faith. The clarity of his exposition and his constant desire to draw out the consequences of historical exposition mean that this book will find a treasured place on the bookshelves of theologians and theology students across the board."--Lewis Ayres, Bede Professor of Catholic Theology, Durham University"This volume is a welcome addition to the trinitarian renaissance of the last decades. Transcending the distinction between 'historical' and 'systematic, ' Anatolios guides us through the work of three key fathers--Athanasius, Gregory of Nyssa, and Augustine. This opens to us the broader coherence of a trinitarian theology, which touches every aspect of Christian existence under the primacy of Christ, and a clear theological epistemology. Retrieving the vision of those who gave shape to Nicaea in this way will, I am sure, bear much fruit and give great shape to Christian vision today."--John Behr, dean and professor of patristics, St. Vladimir's Orthodox Theological Seminary
