Point well taken on the vss 20-21.  There are theologians who are of the mind that the Trumpets are a result of the Christian Church going into error, and admittedly I am partial to this view.  But in fairness, it would seem that text could be addressing much of humanity and not necessarily just medieval Catholicism.

Agreed that Moslems are not exempt from 7 Last Plagues.  Those plagues are in the future.  We are discussing the interpretation of the 5th and 6th Trumpets from the perspective that they are fulfilled already.
