“What is the Prophetic View of Idealism?
“Idealism is the view that the prophecies of the Revelation generally do not have historic referents (or have very few, such as the first and second comings of Christ), but are to be understood symbolically and spiritually (thus drawing spiritual ‘ideals’ from the book). Idealism is most often conjoined with an Amillennial outlook.
“This view has become more popular in Reformed circles during the 1900’s. See B.B. Warfield’s 4 page article below for the best, short, evangelical defense of this view. . .
“Regarding the interpretation of Revelation, we [at Reformed Books Online] recommend a cross between Historicism and Idealism.”
B. B. Warfield was a defender of Biblical inerrancy. He and A.A. Hodge wrote an influential book about this. According to Theopedia.com, “his passion was to refute the liberal element within Presbyterianism and within Christianity at large.” In interpreting Revelation, he was an idealist. The short article linked below was helpful to me in understanding how to approach the genre of apocalypse as it relates to the Book of Revelation. This article is in a pdf format.
