“The diaspora situation of the Church is thus, when seen from the perspective of the gospel, the normal one; whereas the medieval appearance of a ‘Christendom’ closed in on itself, whose opponents—as pagans and Moslems—are located beyond her borders and can be defended against with weapons of power and even pushed back, corresponded to a direct, unmediated insertion of the Old into the New Testament.”
