However, after I did some research, I found it amazing that most of the books of the New Testament have actually been dated by professional scholars and archaeologists very soon after the death of Jesus (there are many books on this subject, such as Bruce Metzger's "The Text of the New Testament: Its Transmission, Corruption, and Restoration"). There is a high degree of certainty that these books really are the words and testimony of actual eyewitnesses to the events they describe (or of those who interviewed those eyewitnesses).
There is such a wealth of information on this subject, I can't begin to summarize it all. However, I would like to talk about one specific issue that I think helps support the notion that most of the New Testament can be said to have been written earlier than 70 AD (at most a mere 40 years after Jesus was crucified).
First let's quickly discuss what happened in 70 AD. The Roman army, led by the future Emperor Titus, besieged and conquered the city of Jerusalem, destroying the city and its temple in 70 AD. It cannot be overstated what a disastrous event this was for the Jewish inhabitants of Jerusalem. As Norman Geisler puts it in his book "I Don't Have Enough Faith To Be An Atheist" (page 237):
"The center of [the Jews'] national, economic and religious life is Jerusalem, and especially the temple. It has been that way in ... almost every Jew's family for a thousand years - ever since Solomon built the first temple."
What is surprising (and something most non-Christians and those unfamiliar with the New Testament are not aware of) is that the Gospels tell us that Jesus actually predicted this destruction (though he did not say exactly when it would happen). See Mark 13:1-2 as one instance where this is documented - Luke and Matthew repeat this, something I will get to shortly).
Why is this important? One of my prior objections to this prediction of Jesus being proof of the dating of the New Testament went something like this: if I was writing a legendary story of a religious figure many decades/centuries after the fact, I would go through history, pick out a very important event that happened, and put words in the mouth of the mythical religious figure "predicting" that important event. Couldn't it be true that Mark (and Matthew and Luke) was written after 70 AD and they simply lied, saying that Jesus predicted it would happen - effectively post-dating this "prophesy"?
Here's the problem with that. Let's take a look at the Gospel of Matthew, specifically these verses:
- Matthew 1:22-23
- Matthew 2:14-15
- Matthew 2:17-18
- Matthew 2:23
- Matthew 3:3
- Matthew 4:13-14
- Matthew 8:16-17
- Matthew 12:15-17
- Matthew 13:13-14
- Matthew 13:34-35
- Matthew 21:2-5
- Matthew 27:6-10
Time after time after time, Matthew makes a point to always explicitly call out when the things he is documenting was predicted by previous prophesies. "All this took place to fulfill what the Lord had said through the prophet", "And so was fulfilled what the Lord had said through the prophet", "Then what was said through the prophet Jeremiah was fulfilled", "This was to fulfill what was spoken through the prophet Isaiah" and on and on. Now take a look at Matthew 24:1-2:
"Jesus left the temple and was walking away when his disciples came up to him to call his attention to its buildings. "Do you see all these things?" he asked. 'I tell you the truth, not one stone here will be left on another; every one will be thrown down.'"
That's it. Just a straight matter-of-fact statement of what Jesus predicted. No "this was fulfilled" or "this has happened just as he said". Nothing. As a example of what I would be expecting, read Matthew 28:5-6:
"The angel said to the women, "Do not be afraid, for I know that you are looking for Jesus, who was crucified. He is not here; he has risen, just as he said. Come and see the place where he lay."
Granted, that is Matthew quoting the angel, but the point here is that Matthew explicitly writes down that one of Jesus' prophesies happened "just as he said". You would think that Jesus being able to successfully predict such a massive and devastating event as the destruction of Jerusalem and the razing of the temple would warrant some kind of mention in or around Matthew 24:1-2, but there is nothing. Not so much as a "just as he said". It is as if, at the time Matthew wrote those words, the destruction of Jerusalem hasn't happened yet!
Take a look at Matthew 28:15
"So the soldiers took the money and did as they were instructed. And this story has been widely circulated among the Jews to this very day"
Note the words I've emphasized here - "to this very day". Here you see Matthew is not averse to mentioning things happening as of the very moment he was writing the words. If that is true, why is there no place in his Gospel a discussion about the destruction of the Jews' "center of national, economic and religious life" (in the words of Norman Geisler)?
Now, keep in mind that most scholars agree that Mark was written before Matthew and Luke. So if Matthew can be said to have been written before 70 AD, then Mark must have been written prior to that date as well. Furthermore, the Gospel of Luke has the same 'problem' - it too mentions this prophesy of Jesus, but also never mentions the destruction of Jerusalem and the temple. And in Luke's case, it is even more puzzling (for those who think he, too, wrote after 70 AD) because of all the authors of the New Testament documents, Luke is the one who does the most painstakingly detailed historical reporting. You would think if anyone, it would have been Luke to have mentioned the destruction of Jerusalem and its temple. But he doesn't.
I'll further quote Norman Geisler again from his book, because he makes a very good point:
"Question: if you and your fellow-followers write accounts of Jesus after the temple and city were destroyed in AD 70, aren't you going to at least mention that unprecedented national, human, economic and religious tragedy somewhere in your writings, especially since this risen Jesus had predicted it? Of course! Well, here's the problem for those who say the New Testament was written after 70 - there's absolutely no mention of the fulfilment of this predicted tragedy anywhere in the New Testament documents. This means most, if not all, of the documents must have been written prior to 70."
Again, this is just one aspect used to help date the New Testament documents. But it's one that I, myself, find very useful. Taken together with the rest of the arguments for the early dating of the New Testament (again, tons of books and articles have been published on this), I found it all very convincing.
