Christians confess that Christ came to save us from sin and death. But what did he save us for? One beautiful and compelling answer to this question is that God saved us for union with him so that we might become “partakers of the divine nature” (1 Pet 2:4), what the Christian tradition has called “deification.” This term refers to a particular vision of salvation which claims that God wants to share his own divine life with us, uniting us to himself and transforming us into his likeness. While often thought to be either a heretical notion or the provenance of Eastern Orthodoxy, this book shows that deification is an integral part of Catholicism, Orthodoxy, and many Protestant denominations. Drawing on the resources of their own Christian heritages, eleven scholars share the riches of their respective traditions on the doctrine of deification. In this book , scholars and pastor-scholars from diverse Christian expressions write for both a scholarly and lay audience about what God created us to be: adopted children of God who are called, even now, to “be filled with all the fullness of God” (Eph. 3:19).

Winner of the 2017 Christian Book Award for New Author Named one of the top books of 2016 by John Piper's Desiring God ministry To experience why the gospel is good news and answer life’s most foundational questions about identity, destiny, and purpose, we must understand what it means to be united to Christ. If you are a Christian, the Bible says that Christ has united his life to yours, that you are now in Christ and Christ is in you. This almost unfathomable truth is the central theme of the Bible from Genesis to Revelation. Yet few Christians today experience or enjoy this reality. Union with Christ reveals the transformational power of this ancient doctrine while addressing the basic questions of the human heart: Who Am I? Why Am I Here? Where Am I Headed? How Will I Get There? Nothing is more practical for living the Christian life than union with Christ. The recovery of this reality provides the anchor and engine for your life with God—for your destiny is not only to see Christ, but to actually become like him.

Deification in the Greek patristic tradition was the fulfilment of the destiny for which humanity was created - not merely salvation from sin but entry into the fullness of the divine life of the Trinity. This book, the first on the subject for over sixty years, traces the history of deification from its birth as a second-century metaphor with biblical roots to its maturity as a doctrine central to the spiritual life of the Byzantine Church. Drawing attention to the richness and diversity of the patristic approaches from Irenaeus to Maximus the Confessor, Norman Russell offers a full discussion of the background and context of the doctrine, at the same time highlighting its distinctively Christian character.

By treating Augustine's passages on deification both chronologically and constructively, Meconi situates Augustine in a long chorus of Christian pastors and theologians who understand the essence of Christianity as the human person's total and transformative union with God.

'Deification' refers to the transformation of believers into the likeness of God. Of course, Christian monotheism goes against any literal 'god making' of believers. Rather, the NT speaks of a transformation of mind, a metamorphosis of character, a redefinition of selfhood, and an imitation of God. Most of these passages are tantalizingly brief, and none spells out the concept in detail.

Foundational to believers' salvation is their union with Christ. In this accessible introduction, Johnson argues that this neglected doctrine is the lens through which all other facets of salvation should be understood.

The doctrine of theosis has enjoyed a recent resurgence among varied theological traditions across the realms of historical, dogmatic, and exegetical theology. In Christification: A Lutheran Approach to Theosis, Jordan Cooper evaluates this teaching from a Lutheran perspective. He examines the teachings of the church fathers, the New Testament, and the Lutheran Confessional tradition in conversation with recent scholarship on theosis. Cooper proposes that the participationist soteriology of the early fathers expressed in terms of theosis is compatible with Luther's doctrine of forensic justification. The historic Lutheran tradition, Scripture, and the patristic sources do not limit soteriological discussions to legal terminology, but instead offer a multifaceted doctrine of salvation that encapsulates both participatory and forensic motifs. This is compared and contrasted with the development of the doctrine of deification in the Eastern tradition arising from the thought of Pseudo-Dionysius. Cooper argues that the doctrine of the earliest fathers--such as Irenaeus, Athanasius, and Justin--is primarily a Christological and economic reality defined as "Christification." This model of theosis is placed in contradistinction to later Neoplatonic forms of deification.
