We can signal here that during the centuries, what we derived from Augustinism prevented Christians from announcing the true hope for the world and also from dialoguing with Muslims on the theme of the eschatological hope - for the world.
Those who reject the salvation of Al-Massih have kept the idea of the salvation of the world, or of an ideal world, but have charged themselves with the execution of the judgment of the world. The massacres perpetrated are an act of judgment from which it is expected an ideal world will emerge, liberated or submitted, but pure and perfect. (Unless that in a satanic nihilism we have no hope at all remaining).
We find this idea in the secularism of the French Revolution where the revolutionaries massacred refractories in the illusory hope of a liberated world. We find it again in the ideal of the Soviet conquest of the world by the Socialist International.
