The Jesus Freaks Will Hate This

[Esquilax]

Having said this, I don't believe that the accounts in the gospels were not from eyewitnesses. Saying that eyewitnesses didn't write the gospels doesn't mean that the accounts were not from people who viewed the events. We don't know who wrote the sources, such as Q, that the synoptic writers relied on, but they were very likely eyewitnesses. If the apostle John was the source for the gospel of John, then the source was obviously an eyewitness to Jesus.

If you don't know who wrote the books, or who made the accounts within them, how can you possibly say whether they were eyewitnesses or not? The gospels could have been written yesterday and you wouldn't know it, with the amount of information you have.
