How can Christian theology confess God as both other than the world and also related to it in a way that compromises neither of these? Most modern thought has offered a simple reply: it cannot. Christ at the Crux analyzes one element of the roots of this denial and charts a route toward rapprochement. The Christologies of eight theologians offer various attempts to relate the Creator and the creature in Christ: Irenaeus of Lyon, Cyril of Alexandria, John Philoponus, Martin Luther, John Calvin, John Zizioulas, Robert Jenson, and Colin Gunton. Within the patristic era the question is grounded in theology about the incarnation; with the Reformers the focus is on the mediation between creation and Creator; and with the three modern theologians the breadth of the issue is completed with theology proper. Together, these eight offer a grand-scale perspective on much of the christological possibilities for conceiving the relation between God and everything else. In the end Paul Cumin shows how the doctrine of the Trinity appears to open new possibilities for Christology and in particular for the way theology about the Spirit enables a reimagining of those items of Christian thought most likely at the roots of our modern rejection of God-as-other.
