You got that right. Many of these Preterists have the audacity to lecture Roman Catholics on the doctrine of Sola Scriptura while they themselves deny the meanings of the scriptures themselves with their allegorical meanderings worthy of their patriarch Origen.
They do with the 2nd Advent prophetical scriptures exactly what the unbelieving Jews do to the 1st Advent prophetical scriptures, they attempt to reason them away with double-talk-'that doesn't really mean that'
If the 1st Advent scriptures were literal and fulfilled to the letter, (and they were) so will be the 2nd Advent ones as well.
We may not understand all of the details, for example, who would have thought that Christ would end up in a manger, in Bethlehem, due to the taxing of Rome and then return back to Galilee
That was a fact that prophecy did not reveal in scripture, and unbelieving Jews, not knowing that Christ had, in fact, been born in Bethlehem,(Mic.5:2) actually used that scripture justify their own rejection of Christ(Jn.7:40-43).
Thus, it is nonsense to say that we are to know in detail how each 2nd Advent prophecy will be accomplished-only that they will.
But one thing is very certain, this generation can see more clearly, with the return of Israel, their control of Jerusalem, new technology, the rise of ecumenalism-the return to Rome, the European Union, ancient Babylon being rebuilt, etc how things could happen.
