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).
