[I]n order to proclaim the greenness of Christianity we do not need any new doctrines or theology. We need simply to return with a new eye and new attention to the Scriptures--to the prophets and psalmists of the Old Testament who proclaim God's continuing concern for all his creation; to the Gospel writers who portray Jesus as the man who communes with the wild beasts and who stills the storm; to St Paul who writes of the cosmic mission of Christ and who sums up the Christian approach to nature in that wonderful passage in his epistle to the Romans in which he portrays the whole created order groaning and in travail for its deliverance and liberation.
