I’ve recently been reading various commentaries on the trumpet judgments in Revelation 8-9. Everybody acknowledges that these judgments are modeled on the Egyptian plagues. Further, John’s description of the trumpet judgments are intensifications of the plagues.
The idealist interpreter must argue that the referent of these judgments are the normal kinds of events that characterize the entire inter-advent period. Further, it is not clear how the famines, diseases, etc. of the inter-advent period differ from those that preceded Christ.
The Egyptian plagues are the type, John’s description of antitype properly escalates the type, but the idealist interpreter must then deescalate the type to something less than the original type.
