Spud,
You said, "Only if the subsequent author was “another witness” rather than someone who was simply drawing on an existing account" - well, possibly there was copying between the evangelists but they may have used other written documents; it's fairly obvious though that the additional material supplied by each would have other witnesses as its source.
Several problems there. First, that’s not fairly obvious at all. If they weren’t just fabricated
ad hoc then “other written documents” must have come from somewhere, and you have no way of telling whether that somewhere is a multiply re-told account from one witness or from several. Second, even if there was more than one witness unless those witnesses and their stories were somehow made not to comingle after the event (standard police practice by the way – that’s why they don’t let witnesses confer) then you have no way of knowing whether any one version influenced any another. Third, you’re still stuck with the basic problem that even if one or more than one person sincerely thought they saw a miracle, there’d be no way to know that one of the other possible (but less thrilling) explanations for what actually happed wasn’t the real one. Fourth…well, you get the picture by now I’m sure.
Now if this was an account of how Cleopatra committed suicide we would expect discrepancies as to the details, but if two sources agreed that her death was suicide then you would accept that as beyond reasonable doubt, since there were two accounts telling us that.
But only if the accounts were independent of each other, and besides suicide is a (tragic but) unremarkable real world occurrence. Unwittingly, that’s quite a helpful analogy though – there’s generally considered enough evidence to think that Cleopatra existed, and that she probably committed suicide too. There isn’t though enough evidence to treat the asp story as historically accurate so it’s treated as myth. Now imagine that the story was that she committed suicide by being eaten by a dragon or some other supernatural cause – how much better still would the evidence have to be for that story to be treated as nothing but a myth too do you think?
We have four accounts of the feeding of the five thousand, two of which give details that suggest that the event did happen (whether miraculous or not). Those were, Jesus asking Philip where they could buy food, and Philip and Andrew both answering; also Luke supplying the information that these two were from the town at which it happened, which makes sense of why they were singled out by the author of John.
That “whether miraculous or not” is rather important here don’t you think? If the story was just “Jesus got the caterers in” that’d be interesting but having more than one witness wouldn’t matter much. Think cornflakes for breakfast again. If though the story was “Then Jesus performed a miracle” you be back to same problems of non-conferring witnesses, non-co-mingling stories, elimination of other explanations, honest mistake etc.
In other words, we believe with a reasonable degree of certainty that Cleopatra committed suicide.
Yes, but not with reasonable certainty that an asp did it, let alone that a supernatural agency was in play. “Cleopatra killed herself” is no more remarkable than, “people had cornflakes for breakfast” so there’s no particular reason to doubt the story.
If the evangelists wanted to convey a lesson in the actions of Jesus in the temple or with the 5000, then the fact that they all include the story is significant and suggests a higher likelihood of truth.
No it doesn’t – see above. “The story” is fine when it’s throwing over a few tables, but you need an awful lot more than “fine” when the supposed explanation for an event is “it’s a miracle”.
Great example, which shows why we can't prove the miracles of Jesus happened.
Or even think they were more likely to have happened than the non-miraculous alternative explanations for them. That’s your problem.
Point of order: we don't know that.
Yes we do. Everything we’ve ever observed, investigated and validated about the world is naturalistic in nature. If you want to posit a non-natural that’s fine, but you have all your work ahead of the you to validate that claim, or even to indicate
how you’d validate it.
POO - they were written within the generation that witnessed it, see Paul's reference to the 500 who were still alive and his reference to the Lord's supper, the resurrection appearances,
I was referring to the resurrection story, and “a generation” is decades.
Point noted. One answer is that there were many many miracles described in detail, so if they were actually corrupted forms of original events then this has taken place on a very large scale. Is that likely to have happened through the process you describe?
There were many, many more miracles than you realise when you include the miracles of Neptune, Thor, Zeus, Ra etc. All that tells you though is that your and these other miracle stories came from more credulous times. How does that help you?
Also, could anyone be clever enough to invent the miracle stories, getting all most of the ordinary geographical and temporal, cultural and historical details correct at the same time?
No-one would have need to invent them in the sense you imply. Rather reaching for explanations that satisfied what they thought they saw would have been good enough. Some caught the wind and are believed to this day (at least by some people); others have been relegated to that status of myth and fable. There’s no reason to think though that the “winners” won because of anything inherently more credible about them than the losers. Had Constantine chosen a different religion rather than Christianity for example, no doubt to this day people like you would be talking approvingly about the miracles of Poseidon and differently about the myths of Jesus.
Or were they simply recording accurately what they saw or were told had been seen?
Again, you can’t record an explanation – you can record an event, but the explanation for it is only the narrative that makes most sense to you at the time using the methods and tools available to you.
