> I would assume that we agree that first hand accounts are stronger evidence than second hand accounts, right?
Yes, agreed. No problem here.
> Well we can't be sure who wrote these documents, so we don't know if they're first hand accounts. So they're weakened by this.
On examination (true examination), the evidence is quite strong that the Gospels were written by Matthew, Mark, Luke, and John. Matthew and John would have been eyewitnesses (first-hand accounts), and possibly Mark to some of what he wrote. So we can be somewhat certain at least 3 of the Gospels were written as first-hand accounts, and so their accounts are not as suspect as you claim.
The reasons to suspect that a Jerusalem Levite wrote Matthew are convincing. Matthew's Gospel also includes 5 large teaching sections not part of the other Gospels. And the unanimous attribution of the early Church (hard, external evidence) is that Matthew was the author.
The reasons to conclude that a Jerusalem native but now in a Gentile environment (Mark's situation) are convincing. Mark's family were Jerusalemite believers. There are suspicions that Mark was a some-time follower of Jesus. Mark's level of Greek fits the situation. No one in their right mind would have attributed the first Gospel to Mark if they were making up an author. And the unanimous attribution of the early church is that Mark was the author. This is far stronger than you claim, and not a "weakness" to reliability.
That John is an eyewitness account is the strongest of the 4. His Gospel is riddled with eyewitness touches. He claims himself to be the author. The unanimous attribution of the early church was for John. The style and content of the writing fits all we know about John. The case is weighty for his authorship. This is not so weak as you imagine it to be.
> They were written decades after the event. They are weakened by this.
Possibly. Though the far majority of scholarship puts Mark in the 60s, Mt & Lk. in the 70s-80s, and John in the 90s, this is not necessarily so. A strong case can be made for Mk in the 50s and the other 3 in the 60s. Some scholars even put Mark in the 40s (which I think is rash). Bottom line: we don't really know when they were written, so it's a weak case to claim their date of writing weakens their reliability. If Mark were written in the late 50s or even early 60s, that's only 30 years after the events. That's like us writing about President George Bush: not a problem. Secondly, most ancient records we have were written far more than decades after their subjects (even Tacitus and Suetonius). To have ancient writings within decades of their subjects is spectacular in the perspective of historians. It doesn't weaken the case, it strengthens it.
Ultimately we have to ask: If the documents weren't written contemporaneously with the events, does that tell us whether it's true? I say it does not. I read "Lincoln" by David Herbert Donald (
https://www.amazon.com/s?k=biography+of+abraham+lincoln&crid=1HS17DDGII6SI&sprefix=biography+of+Abr%2Caps%2C160&ref=nb_sb_ss_i_1_16), who lived from 1920-2009. Should I throw the biography away? It was written more than a century after Lincoln's life.
> They conflict, they are weakened by this.
> They also seem to plagiarize from each other
Now wait a minute. Are the conflicting accounts (very different), or identical (or very similar) accounts? You can't argue it both ways. Make up your mind, and we can talk.
Regardless, we have other conflicting accounts from ancient historians, but no one doubts the historicity of the events themselves. This doesn't weaken the historicity, only leaves us wondering about some minor details about it.
> possibly some mystery document named document Q I believe is the name
Yeah, "Q" is the name, but there is no evidence for it. Totally speculated, possibly fictional. You can't really make a case here. No one in the ancient world mentions such a document, there is no copy of it, and no evidence for it. This is not a strong part of your argument.
> If they colluded, then they aren't independent accounts.
There's no evidence of collusion. Should we appoint a special counsel?

> The earliest tiny little scrap that we have of these documents are from over a hundred years after the event even occurred and its tinier than a cocktail napkin. This weakens them.
Why does this weaken them? We have none of the originals of Alexander the Great's 4 biographies. We have none of the originals of Suetonius's or Tacitus's writings. We have none of the originals of Josephus's writings. We have, in actuality, very few originals. That we have a parchment copy of John from AD 125 is amazing, and that we have literally thousands in the first several centuries is unparalleled. Actually, our documentary evidence for the New Testament is way WAY stronger than ANY other ancient document, yet none of those are "weakened."
> We only have 4 of them. That's not very many.
By ancient standards, 4 is SPECTACULAR. We wish we had four sources for anything ancient. The truth is, we have fewer than 4 for almost everything in the ancient world.
So to summarize:
- We can be fairly sure we know the authors, so that case is reasonably strong
- We can be fairly sure at least 2 of the 4 authors were eyewitnesses, and possibly a third, so that case is reasonably strong. And the 4th author is known as a diligent and reliable historian. We have quite a strong case for reliability across the board.
- To have 4 accounts is quite good.
- To have 4 accounts written within a few decades is quite good.
- To have 4 accounts that corroborate as much as they do is quite good.
- To have the abundance of manuscript evidence we do, including 1 as close as 100 years, is quite good.
The bottom line: all of these features and qualities give strength to the reliability of the record we have. They are nothing like a "stain" on the accounts.
> But, please note one thing: when we talk about reliability, its a contextual question. The real question is "are they reliable enough for what?". This level of evidence might be okay if someone wanted to show that Ceasar liked jogging in the mornings or something. It is quite a different matter if they want to show that Ceasar levitated up to the heavens, touched the sun with his bare hands, and came back down.
Evidence is the same for simple as for more extreme claims. The case comes down to: (1) Is our source telling the truth? (2) Can he be trusted? What reasons do we have to believe? What reasons to do we have to doubt? (3) Is there corroborating evidence from other witnesses or from material artifacts? (4) Can anything be verified? (5) What reason might we have to suspect dishonesty or bias?
It doesn't matter whether it's a morning jog or a flying Caesar, the task of evidence and the burden of evidence are the same: Is the source ultimately reliable?
Looking very briefly at the evidence for the resurrection:
- We have four independent accounts. The resurrection accounts are very different, so there was certainly no copying or no collusion. Colluding eyewitnesses work out their story; so also conspirators. But the Gospels accounts of Jesus's life have many similarities, so we know the authors were giving their own take on the resurrection. This is exactly what a detective wants: similar touchpoints but different perspectives. discrepancies can be very valuable. Witnesses never agree totally about reports in every detail. This gives credibility to the resurrection account.
- Thallus, Tacitus, Lucian, and Josephus mention details of Jesus's death recorded in the Gospels. There is at least some corroborating evidence surrounding his death, affirming the accounts of the Gospel writers.
- The Apostle Paul, a one-time hostile to Christianity who was later convinced and became a strong advocate, missionary and theologian, gives evidence of the crucifixion and resurrection. He was not just a believer with bias.
- We know the accounts were not modified over time because we have a chain of custody.
- Other than people's a priori rejection of the possibility of miracles, i.e., bias, there is no reason to doubt the Gospel accounts of the resurrection. It squares with the material evidence, the eyewitness testimony, and the religious and cultural results immediately following (the birth of the Church).
- There's no rational reason to consider the authors to have been biased. They had nothing to gain (money, sex, power, fame) and everything to lose. There was no expectation of a physical resurrection. Their theology didn't demand a resurrection (before it happened). Such a claim only had potential to garner mockery and scorn.
> Imagine if this is the evidence that we had, but the claim was that bigfoot is real. Would you believe in bigfoot?
No. Bigfoot has nothing near the quality of evidence or the quality of testimony. It's a false comparison designed to denigrate but without substance. It's just not the same at all, and not even in the same league.
