The Perfectly Simple Triune God

A particularly nettlesome question is that around the relationship of the confession of God as a simple yet threefold being—the treatises of the one God and the Trinity. Although God as simple and Triune was widely accepted for over a millennium, simplicity has been widely critiqued and rejected by modern theology. The purported error is in conceiving God’s unity prior to the Triune persons, an error begun by Augustine and crystallized in Aquinas. The Perfectly Simple Triune God challenges this critique and reading of Aquinas as a misunderstanding of his doctrine of God. By refusing to begin theology with God’s oneness, who God is collapses into who God is for us, a loss of the biblical and dramatic character of God for us. D. Stephen Long posits that the two treatises were never independent, but inextricably related and entailing one another. Long provides a constructive rereading of Thomas Aquinas, tracing antecedents to Aquinas in the patristic tradition, and readings of him through to the Reformers, taking into account challenges to the classical tradition posed by modern and contemporary theology and philosophy to offer a robust articulation of divine Trinitarian agency for a contemporary age that adheres to broadly considered orthodox and ecumenical parameters.

Describing Jesus as an “agent” of divine actions, or as one who possesses human “agency,” is commonplace in christological discussions. Yet these discussions often wade in a shallow understanding of the terms' meanings and the theological implications of such claims. For example, while many theologians who are committed to the definition of Chalcedon consider Jesus one agent, we might ask if this implies that the triune God comprises “three agents?” Or, if Christ possesses “singular agency,” how are his divinity and humanity operative in his actions? In response, this work draws from the theology of John Owen and advancements in philosophy of action in order to offer an account of divine and human agency in christological action from within the Reformed tradition. It provides clarity to the christological and trinitarian uses of the language of “agent/agency” in Christ and attends to the theological (esp. trinitarian) entailments therein. While at first glance there may appear to be internal inconsistencies with accounts that subscribe to classical trinitarianism and Reformed Christological agency, this book argues that Owen helps us recover an understanding of christological agency that is internally coherent and theologically prudent. As such the Reformed tradition can articulate Christological “agency” in a way that is coherent with the testimony of Scripture, the ecumenical councils, and classical trinitarianism while contributing to contemporary theological discussions. The case not only provides terminological clarity and theological coherence, but also inclines Christians to appreciate the trinitarian love of God in Christ's action and the human sympathy of Christ for his people.

The Christian claim that the triune God is the creator of the universe is both exegetically grounded and theologically rich. Yet discussions about God's work of creation are often overwhelmed by questions such as the age of the earth and the relationship between divine creation and evolution. Without completely ignoring such issues, Peter Leithart offers a decidedly theological interpretation of the creation account from Genesis 1. By engaging with classic discussions of creation, including those of Plato and Aristotle, as well as Christian articulations as varied as those of Augustine, Thomas Aquinas, Martin Luther, Sergius Bulgakov, Karl Barth and Robert Jenson, Leithart embraces the challenge of talking about God and God's first work. Here, readers will discover what it means to articulate a theology that is rigorously grounded in the first chapter of the Bible and the creedal affirmation of God the Father almighty, who is the creator of the heavens and earth.

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.

Most contemporary presentations of the Christian God focus on either his 'oneness' or his 'relationality'. These are often assumed to contradict one another, and language about God's love and relationality often settles into a comforting but ultimately shallow and unreliable gesture towards bland niceness. Peter Sanlon offers a fresh, stimulating examination of the triune God who is love. He guides us through the classical theological tradition of Augustine, Anselm and Aquinas - aiming to help us think and speak more faithfully about God. In Part One, Sanlon introduces the vital concept of 'simplicity', without which it is impossible fully to affirm all the Bible teaches about God. Part Two examines the relationality of God's love in Scripture. The author considers the importance of God's simplicity for the atonement, and concludes with some reflections on how Christians will be better equipped to engage with contemporary culture if they remain sensitive to both God's simplicity and his relationality.

Without a proper understanding of sin, there can never be a proper understanding of the gospel. Sin is opposed both to God's will and to nature, leaving us in need of God's grace and redemption. This comprehensive exploration of the doctrine of sin looks at what the Bible teaches about sin's origin, nature, and consequences, engaging with historical and contemporary movements. Dealing with difficult issues such as original sin, angelic sin, corporate sin, greater and lesser sins, and more, this book ends with a discussion on divine grace, which is the only hope for the problem of sin.

John C. Peckham introduces and engages with major questions about God's nature and how God relates to the world. Does God change? Does God have emotions? Can God do anything? Does God know the future? Does God always attain what God desires? And is God entirely good? This textbook provides a clear and concise overview of the issues involved in these and other questions, exploring prominent contemporary approaches to the main issues relative to how to conceive of the God-world relationship within Christian theology. In so doing, Peckham surveys a range of live options regarding each of the primary questions, briefly considering where each falls within the spectrum of the Christian tradition and providing clear and readily understandable explanations of the technical issues involved. The result is a stimulating survey of the most prominent options in Christian theology relative to divine attributes and the God-world relationship, offered in an accessible format for students. Designed for classroom use this volume includes the following features: - study questions for each chapter - suggestions for further reading for each chapter - glossary
