In this sequel to The Way to Nicaea, Fr John Behr turns his attention to the fourth century, the era in which Christian theology was formulated as the Nicene faith, the common heritage of most Christians to this day. Engaging the best of modern scholarship, Behr provides a series of original, comprehensive, and insightful sketches of the theology of the key protagonists of the Nicene faith, presenting a powerful vision of Christian theology, centered upon Christ and his Passion. Part One, True God of True God, opens with a refl ection on the nature of Christian theology, challenging common presuppositions, and an analysis and survey of the fourth century controversies, followed by studies of Alexander, Arius, the Council of Nicaea, and, Athanasius. Part Two, One of the Holy Trinity, provides analyses of the work of Basil of Caesarea, Gregory of Nazianzus, and Gregory of Nyssa, together with their opponents, in particular Eunomius and Apollinarius.
