What do you think "delivered to us" means? You think a scribe came and literally handed him a bunch of manuscripts signed by eyewitnesses?
I think we tend to place a modern-western thought to the culture of 2000 years ago. If I deliver to you a verbal message - I delivered to you personally the message.
If after being with someone for 30 years and write a "biography" - it probably is worth the read.
He's most likely referring to oral traditions that were passed down over time, which is how the stories tended to be passed down before they were actually written down. So again, not eyewitness accounts.
No... that isn't what it says. (Again, you can disagree with me but it still isn't what it said)
Luke's account is definitely not that of an eyewitness. He would have had to have witnessed the events himself, in order for that to be the case.
In Luke he is talking about the time when the Apostles were with Jesus. In Acts, he hung around the Apostles (as well as Paul). So, you are right... he isn't the "eyewitness" of the life of Jesus... but he did speak, hung around with, heard the preaching of what happened, watched the miracles et al when he hung around them in the book of Acts.
Now... I know you are skeptical and I am fine with that. But there isn't anything that debunks my logic (yet)
