Hope is the leitmotiv of Jurgen Moltmann's theology. Not merely one aspect of his project, hope is the whole of it, the supreme doctrine interpenetrating all others. Indeed, hope is his method. The present study is both historical and developmental while also being analytical and interrogative. This chronological exploration seeks to show the nature, composition, and development of Moltmann's doctrine of hope, as the distinctive doctrine of his theology, implicating all others. Part I establishes Moltmann's doctrine of hope as grounded in God's faithfulness in the cross and resurrection. Part II investigates major doctrines in his project in light of this ground. This design seeks to take advantage of the chronological approach while also integrating the best elements of a topical approach.
