"Though full preterist systems don't deny that spiritual truths can be applied from the events of AD70, the idealist takes exactly the opposite view -- that AD70 itself was an application (outward show) of eternal spiritual realities - and was not the Substance in itself. (Not "Re-Fulfillment"!)"
"The differences between Preterism and Idealism are actually quite fundamental, resulting in a countless number of divergences. The key difference is in where one sees the ultimate realm of prophetic fulfillment -- whether seeing prophecy referring exclusively to natural events (and their consequential spiritual application) fulfilled once-for-all in history, or in seeing Israel's prophecies and natural events as pictures signifying the greater realities fulfilled eternally in Christ, as is the case with modern forms of Idealism. "
"Here is my plainest assessment of the danger, in terms that any seasoned Full Preterist should be able to understand: The valor and determination of Full Preterists to conquer error is like the Roman soldiers who first came upon Jerusalem, and who, simplistically seeing an opening overzealously charged up to her very gates, only to find themselves suddenly surrounded on all sides (with Providence alone saving the life of Titus). Full Preterism, driven by its initial sincere and noble desire in the pulling down of Futurist error, has charged too hard and far in the setting up of perceived truth, having incorrectly assessed the situation due to the speed of attack, and the pride that always comes with easy victories. There is no question that Jerusalem's history is rich with theological wealth and meaning ; however, she was - and will always be - a deadly harlot who betrays those who succumb to her alluring charms. If you approach too closely to her she will strike you like the serpent she is -- and her poison goes straight to the brain. Please consider my decade of leadership experience in the movement -- and my observation of countless people in this situation -- by accepting at face value my warnings for what they are - sincere attempts to help . If you have gotten too close to the harlot, having lost your senses in wonderment (as did John prior to being rebuked), AWAKEN AT ONCE while you are still able !! Set your eyes upon the spotless bride instead of the filthy whore, and you will be saved to carry on the battle with the Banner of Truth."
