cullmann's studies on christian eschatology and christology drove him to propose a third position over against the popular positions of c. h. dodd and albert schweitzer, known as "redemptive history" or "inaugurated eschatology". he wrote that jesus christ was the midpoint of sacred history, which informs general history and runs linearly from creation to consummation. he stressed the objective reality of sacred history against the existentialist interpretation of rudolf bultmann, a fellow german theologian. cullmann suggested the analogy of d-day and ve-day to illustrate the relationship between jesus' death and resurrection on the one hand, and his "parousia" on the other.
