Divine Simplicity

A Fresh Articulation of the Unity of God This volume critiques various ways divine simplicity--which suggests God's being is identical to God's attributes--has shaped Christian theology and offers a fresh articulation of the unity of God. The author proposes that the concept of divine simplicity, carried over from the Greek metaphysical tradition, was heedlessly incorporated into the language of Christian trinitarian theology during the patristic period. He identifies numerous problems that have resulted from its retention in postpatristic Christian dogmatics, arguing that uncritical use of the concept renders the biblical God inexpressible and unknowable. This major contribution to contemporary trinitarian dogmatics also contains a unique approach to the problem of Christian-Muslim relations.

The doctrine of divine simplicity has long played a crucial role in Western Christianity's understanding of God. It claimed that by denying that God is composed of parts Christians are able to account for his absolute self-sufficiency and his ultimate sufficiency as the absolute Creator of the world. If God were a composite being then something other than the Godhead itself would be required to explain or account for God. If this were the case then God would not be most absolute and would not be able to adequately know or account for himself without reference to something other than himself. This book develops these arguments by examining the implications of divine simplicity for God's existence, attributes, knowledge, and will. Along the way there is extensive interaction with older writers, such as Thomas Aquinas and the Reformed scholastics, as well as more recent philosophers and theologians. An attempt is made to answer some of the currently popular criticisms of divine simplicity and to reassert the vital importance of continuing to confess that God is without parts, even in the modern philosophical-theological milieu.

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.

Unknown to many, increasing numbers of conservative evangelicals are denying basic tenets of classical Christian teaching about God, with departures occurring even among those of the Calvinistic persuasion. James E. Dolezal’s All That Is in God provides an exposition of the historic Christian position while engaging with these contemporary deviations. His convincing critique of the newer position he styles “theistic mutualism” is philosophically robust, systematically nuanced, and biblically based. It demonstrates the need to maintain the traditional viewpoint, particularly on divine simplicity, and spotlights the unfortunate implications for other important Christian doctrines—such as divine eternality and the Trinity—if it were to be abandoned. Arguing carefully and cogently that “all that is in God is God Himself,” the work is sure to stimulate debate on the issue in years to come.

Hughes discusses Aquinus' work regarding the apparently irreconcilable theses of natural and revealed theology, and he argues that Aquinas fails in his attempt to reconcile absolute simplicity with the doctrines of the Trinity and the Incarnation. Hughes also offers a provocative account of divine simplicity and explores its implications for the Thomistic doctrines of the Trinity and Incarnation.

After an age of original integrity, the doctrine of divine simplicity fell from grace. Once a cornerstone of orthodox Christianity's doctrine of God, many modern theologians expelled it from the garden, especially since it often employed now-passé Platonic and Aristotelian metaphysics. But was the doctrine of divine simplicity's fall deserved? Is it unreasonable to hold that God is metaphysically without parts? Is the Lord really one?Rather than dismiss the challenges leveled against divine simplicity by modernity, The Lord is One engages them. The contributors advance in the belief that modernity cannot and should not be escaped, but they do not hesitate to critique currents within it. Thus, this volume presents exegetical, historical, and theological treatments of divine simplicity. It argues the doctrine of divine simplicity is cogent and indispensable while also making space for historically marginalized or idiosyncratic articulations of it. After all, once expelled from the garden, nothing returns exactly as it was.

There has been a recent revival of interest in the doctrine of divine simplicity in systematic and philosophical theology, following decades of intense reflection on the tri-personhood of the Christian God. While recent studies have produced a greater appreciation of patristic and scholastic theologies, they have not yet engaged in dialogue with proponents of the trinitarian revival that emerged in the latter half of the twentieth century in anything other than polemical terms. This book offers a theological defense of the doctrine of divine simplicity through careful reading of both exemplary historical theologians and Robert W. Jenson, an important American contributor to the trinitarian revival. After tracing continuities and discontinuities amongst select historical theologians, the book approaches Jenson with a multivalent account of divine simplicity. The result is a more nuanced interpretation of Jenson’s theology, an account of divine simplicity that responds to perceived problems, and new constructive proposals for divine simplicity in trinitarian theology.

This updated edition by one of the world's leading apologists presents a systematic, positive case for Christianity that reflects the latest work in the contemporary hard sciences and humanities. Brilliant and accessible.
