“Vid. Iren. Hær V. 26, 2” (R.W.C.).  The passage is quoted by Eusebius (Eccl. Hist. iv. 18), from a lost work of Justin M. Against Marcion:  “Justin well said that before the coming of the Lord Satan never dared to blaspheme God, as not yet knowing his own condemnation, because it was started by the prophets in parables and allegories.  But after our Lord’s advent having learnt plainly from His words and those of the Apostles that everlasting fire is prepared for him,.…he by means of such men as these blasphemes the Lord who brings the judgment upon him, as being already condemned.” S. Cyril seems to expect that Antichrist will be an incarnation of Satan, as did Hippolytus (de Antichr. § 6):  “The Saviour appeared in the form of man, and he too will come in the form of a man.”
