Years ago (not sure how many) one of the preterist brothers said regarding the scripture "all has been fulfilled".
In addition everything in scripture which speaks of an apocalyptic event is an allegory and/or spiritualized by the preterist.
With that formula one can make the scripture say whatever one desires.
To me this is the scripture which is of the greatest difficulty for the preterist:
Acts 1
8 But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth.
9 And when he had spoken these things, while they beheld, he was taken up; and a cloud received him out of their sight.
10 And while they looked stedfastly toward heaven as he went up, behold, two men stood by them in white apparel;
11 Which also said, Ye men of Galilee, why stand ye gazing up into heaven? this same Jesus, which is taken up from you into heaven, shall so come in like manner as ye have seen him go into heaven.
Facts
It was a visible ascension.
"This same Jesus" - not Titus.
"Shall so come in like manner" - visibly back down through the atmosphere - "every eye shall see Him".
Logic:
There is still sin and death on planet earth.
Will it continue on forever? The preterist cannot answer this because they say "all has been fulfilled" and have no eschatalogical scripture to reference concerning this question.
Another question: Do preterists have communion? If so why? because the command is to do it "till He come"
These are just a few objections to preterism.
All systems of eschatology have their problems, IMO, full preterism has the most.
Brother Tom and I and several others had a lengthy debate concerning preterism vs futurism a few years ago, scan the BB archives and you will see all the objections and rebuttals.
The "bottom line" : Indeed there is much allegory, types and figures of speech in the scripture. Rightly interpreting the whole counsel of God is the key.
Personally, I leave room for those who hold to preterism, I don't believe it is a heresy, they do believe in the second coming, just different than traditional Christianity
