This approach was first developed by Geerhardus Vos, especially in his 1930 work, "The Pauline Eschatology". Later, Oscar Cullmann sought to combine the "thorough-going eschatology" of Albert Schweitzer with the "realized eschatology" of C. H. Dodd. Cullmann suggested the analogy of D Day and V Day to illustrate the relationship between Jesus' death and resurrection on the one hand, and his "Second Coming" on the other.
