Here are three quotes from something I recently read on the subject.
Walter Veith said:Revelation 9:1-2 The Fifth Trumpet, The First Woe: Many Christian expositors, including Martin Luther, the great Reformer; Sir Isaac Newton, the famous scientist; and the historian, Edward Gibbon; have seen in the fifth and sixth trumpets the rise and progress of Islam. In view of the tremendous military, religious, economic and cultural impact Islam has had on the Christian world in the nearly fourteen hundred years since its rise in the 600s, this interpretation deserves our serious attention.
Francis Nigel Lee said:It does seem that the fourth iron kingdom was in fact both the pre-Papal and the pre-Islamic undivided Pagan Roman Empire, as well as the later Western-Roman Papal and the contemporaneous Eastern-Roman Islamic Empire into which it then subdivided. Indeed, both “Mahomet” and “the Pope” – as we have already seen – Dr. Calvin called “the two horns of Antichrist.” Thus they correspond to the two legs of the later Roman Empire – Islam and the Papacy.
What think ye? Does Revelation Chapter 9 reference Islam?Reg Barrow said:There are two great antichristian religious systems of deceit revealed in the book of Revelation. The “great western antichrist” of Roman Catholicism (Rev. 17 and 18) and the “great eastern antichrist” of Islam (Rev. 9). This has been the majority position of historic Protestant interpretation (Historicism) for centuries, though later writers often see this with more clarity.
