For two thousand years, Christian theologians have struggled to explain the believer's union with Christ. What sort of union is it? How can it be fully described? This book is an attempt to join the conversation to explore exactly what it means to be in union with Christ. This book will argue that the believer's union with Christ can rightly be presented as a third type of perichoresis. Perichoresis is a word that describes the way the persons of the Trinity interrelate, without losing their essential oneness nor without being absorbed into each other. In short, the doctrine of perichoresis preserves the unity and diversity within the Godhead. It is also used to describe the hypostatic union of the divine and human in Christ. In Perichoretic Salvation, James Gifford argues that the union of the believer and Christ is a relationship of the same kind, though of a third type. Arguing from a perspective that is rooted biblically, historically, and theologically, the book will allow the union to be explained more fully than in the past while remaining within the bounds of what the church has taught over the centuries. It may prove to be a basis for understanding the work of Christ afresh for the twenty-first century.
