Of course that proves THAT Matthew 24:1-13 has been fulfilled. It doesn't disprove that the rest of the Olivet Discourse has also been fulfilled. You have no proof that verses 14-41 have not been fulfilled.
I have PLENTY of proof. It's called the encyclopediae before me, other history boox I have or have read, and a whole internet-full of history, & the occurrence of those events is not found in any of them.
You can't say these are separate events when Jesus makes it so clear they were the same. The escaping Jewish Christians had no idea how long the Roman army would be gone, so they split right away.
Not according to some of their own writings. They left within days, but most of them collected what items they could pack.
It is odd that nobody really seems to know why the Romans left.
Then, call me "nobody". While Vespasian was there, Nero killed himself as Otho had rebelled &led an army against him; Otho became very unpopular & killed himself; Vitellius succeeded him, but began a spell of murders. The army recognized vespasian as Caesar, & he left Jerusalem with his army to get rid of Vitellius, which he did, & became Caesar himself. That took about 8 months, & when V was settled in, he sent his son Titus, an able & popular general, to suppress the Jewish revolt, which was mainly being waged by the Zealots.
It could only be that God, in His infinite grace, provided the means of escape for His children. The idea that this is about a modern event is pure fantasy. In Luke 21:20-24, Jesus tells His disciples "when you see Jerusalem surrounded by armies...flee to the mountains". This language is nearly identical to what we see in Matthew 24:15-20. The only difference is that Matthew places the warning a few verses later. The only way you can believe these are two separate events is to presume they are in order to fit your view.
Again, Jesus had warned them to flee AT ONCE when the armies appeared. He didn't say to flee when they DISappeared, which is what they did.
You are a pretty good historian, to be sure. However, you are not very good with the ancient Greek language. The Greek word "oikumene" means "the inhabited earth", which refers to the Roman Empire.
Better study s'more. Oikumene means just what you first said-the inhabited earth. It's not at all limited to the Roman empire except in some pret imaginations & wishful thinkers.
On the other hand, the Greek word "kosmos" refers to the entire world. "Oikumene" (the Roman Empire) is the same word used in each of these cases. Augustus was taking a census of the Roman Empire. Jesus did not change the word from "oikumene" to "kosmos". Same thing with the gospel spreading throughout the entire world - this was not "kosmos", but the Roman Empire.
"Kosmos" means the universe. You're still swinging & missing.
We Preterists do not reduce anything Jesus said to mere symbolism. Jesus clearly used symbolic and figurative language other times - "I am the Door", "I am the True Vine", "Destroy this temple, and in three days I will raise it up", etc. I have shown that OT prophecies often use symbolism. Yet, you act as though it is beneath Jesus to use symbolic language; that you must apply a wooden literal view to what He said. Why? If you would drop your anti-preterist bias, you might actually learn something new.
Knowing His time was short, Jesus answered His disciples literally.
Now, if the trib had occurred in 66-70 AD, it woulda made Jesus a liar twice. First, the siege of J was NOT the worst event in man's history by a long shot, & not even the worst thing to have happened to the Jews. The nazi holocaust was far-worse, killing a lot more Jews than the siege of J did. And Jesus said He[d return IMMEDIATELY AFTER the trib. So, if the trib was then, he's long-overdue !
In trying to justify the pret myth, you're still trying to teach a pig to roller-skate. I suggest you look at the EVIDENCE against it.
And, BTW, the only prets I have anything against are those authors who spread the pret garbage, such as Gentry & Preston. IMO, they're simply fulla baloney.
