Nineteen chapters of Revelation converted to notes, including the defeat of the Antichrist and the False Prophet. Satan's defeat is next. Only three chapters to go!
The bad news is that the Catholic study guide I'm using says that the defeat of Satan and his minions is a spiritual battle, not a physical one. Jesus slays the opposing armies with a sword coming out of his mouth (i.e. the word of God). They didn't convert in spite of countless disastrous warnings from God (seven seals, seven trumpets, seven woes), so I'm guessing seeing a preacher-king on a white horse isn't going to hold much sway either. Interestingly, Jesus arrives from heaven with his armies of angels and followers, yet He personally slays the armies of the world by himself. So why the show of force?
Protestant Dispensationalists interpret Revelation as involving a real battle on Armageddon, so the Catholic interpretation is rather anticlimactic, which isn't what you want at the end of a trilogy. Needs work.
P.S. New title for the book series: Satan's Last Stand. Seems like it might be an equally appealing title to Christians and non-Christians. Requiem for Heaven and Earth was a little too obscure given that many Christians don't understand the imagery behind Revelation. Some parishes don't even like to teach it out of fear of scaring Christians.
