The victory over the Dragon, according to St. John, does not take place by means of a cataclysmic event at the end of history, but by means of the cataclysmic event that took place in the middle of history: the sacrifice of the Lamb. The language used to describe the basis of Michael’s conquest has nothing to do with the Second Coming, but it has everything to do with the First Coming… When, therefore, did Satan fall from heaven? He fell, definitively, during the ministry of Christ, culminating in the atonement, the resurrection, and the ascension of the Lord to His heavenly throne.”  –David Chilton, The Days of Vengeance, pp. 315-16, on Revelation 12:10-11
