Divine simplicity is the idea that, as the ultimate principle of the universe, God must be a non-composite unity not made up of parts or diverse attributes. Radde-Gallwitz explores how this idea was appropriated by early Christian theologians from non-Christian philosophy with particular reference to Basil of Caesarea and Gregory of Nyssa.

Studying the early church can feel like entering a maze of bishops, emperors, councils, and arcane controversies. This book introduces early Christian theology by focusing on one particularly influential figure, Basil of Caesarea (ca. AD 330-378). It views Basil against the backdrop of a Roman Empire that was adopting Christianity. In Basil's day, Christians were looking for unity in the teaching and practice of their faith. This study acquaints the student with Basil's brilliant--and often neglected--theological writings. In particular, Saint Basil's reflections on the Trinity emerge from these pages as fascinating and illuminating testimonies to the faith of early Christians.

"Gregory of Nyssa is firmly established in today's theological curriculum and is a major figure in the study of late antiquity. Students encounter him in anthologies of primary sources, in surveys of Christian history and perhaps in specialized courses on the doctrine of the Trinity, eschatology, asceticism, or the like. Gregory of Nyssa's Doctrinal Works presents a reading of the works in Gregory's corpus devoted to the dogmatic controversies of his day. Andrew Radde-Gallwitz focuses as much on Gregory the writer as on Gregory the dogmatic theologian. He sets both elements not only within the context of imperial legislation and church councils of Gregory's day, but also within their proper religious context-that is, within the temporal rhythms of ritual and sacramental practice. Gregory himself roots what we call Trinitarian theology within the church's practice of baptism. In his dogmatic treatises, where textbook accounts might lead one to expect much more on the metaphysics of substance or relation, one finds a great deal on baptismal grace; in his sermons, reflecting on the occasion of baptism tends to prompt Trinitarian questions."--Publisher's website.

Steven J. Duby examines the doctrine of divine simplicity. This discussion is centered around the three distinguishing features: grounding in biblical exegesis, use of Thomas Aquinas and the Reformed Orthodox; and the writings of modern systematic and philosophical theologians. Duby outlines the general history of the Christian doctrine of divine simplicity and discusses the methodological traits and essential contents of the dogmatic account. He substantiates the claims of the doctrine of divine simplicity by demonstrating that they are implied and required by the scriptural account of God. Duby considers how simplicity is inferred from God's singularity and aseity, as well as how it is inferred from God's immutability and infinity, and the Christian doctrine of creation. The discussion ends with the response to major objections to simplicity, namely that the doctrine does not pay heed to the plurality of the divine attributes, that it eradicates God's freedom in creating the world and acting toward us; and that it does not cohere with the personal distinctions to be made in the doctrine of the Trinity.

Gregory of Nyssa's Contra Eunomium, one of the major books on trinitarian theology of the 4th century, documents the exchange between Eunomius and the Cappadocian Father in the last episode of the so-called "Arian Crisis". The present volume is devoted to the third and last book of Contra Eunomium. It offers a fresh English translation with a running commentary in the form of ten studies by first-rank specialists. Seventeen shorter papers enlighten various aspects of Contra Eunomium and other writings of the same author. The contributions will be of interest for scholars of historical and systematical theology, philosophy, spirituality, rhetoric and the history of the Early Church.

This book offers a theological, and more specifically ecclesiological, response to the philosophical problem of divine hiddenness. It engages with philosopher J.L. Schellenberg’s argument on hiddenness and sets out a theologically rich and fresh response, drawing on the ecclesiological thought of Gregory of Nyssa. With careful attention to Gregory’s work, the book shows how certain ecclesiological problems and themes are critical to the hiddenness argument. It looks to the gathered church (the church as the body of Christ) and the scattered church (the church as the image of God) for relevance to the hiddenness problem. The volume will be of interest to scholars of theology and philosophy, particularly analytic theologians and philosophers of religion.

How do we speak about God if God is ineffable? This paradoxical question lies at the heart of one of the strangest traditions of philosophical and theological thought: negative theology. As a tradition of thought, negative (or apophatic) theology can be traced back to the convergence of Greek philosophy with Jewish and Christian theology in the first century CE. Beginning with a seemingly simple claim about the ineffability or unsayability of God, negative theology evolved into a complex tradition of thought and spirituality. Today, together with a growing interest in patristic and medieval studies, negative theology enjoys renewed attention in contemporary philosophy and theology. This short introduction presents an overview of how the tradition developed from antiquity until present.
