Book excerpt: "The structural core problem of the Gnostic dualism between the god of creation and the god of redemption governs not only every religion of salvation and redemption. It is immanently given in every world in need of change and renewal, inescapably and ineradicably. The lord of a world in need of change, that is, a misconceived world and the liberator, the creator of a transformed, new world cannot be good friends. They are, so to speak, enemies by definition." Whether Theodor W. Adorno and Walter Benjamin, or Erich Auerbach and Hans Blumenberg, Ernst Bloch and Jacob Taubes, or Carl Schmitt (cited above)--all of them have been more or less fascinated or awed by the dualistic theology of St. Paul's disciple Marcion, and have as prominently and as differently referred to him. Already Adolf von Harnack, author of the Marcion monograph that even today sets the standard, was aware of the timeliness of his research object, in view of a modern Marcionism, right after the First World War.
