Perhaps they don't claim the supernatural, but you can't really demand more historical evidence for the gospel. When what you've got is miles better than any comparable text, it just doesn't make sense to demand more evidence (at least more of that type of evidence.)
Actually, you can. For example, the supernatural claims in the gospels are quite contextual of the time. Many people claimed hallucinations of dead bodies, and many people were believed. There is no evidence suggesting that Jesus physically rose from the dead, there were claims of sightings of the body, but in that age claims images of dead bodies were common, they never believed the physical body left its resting place, nor is that referred to anywhere.
I'm sorry, but the gospels claim that the tomb was indeed empty.
Matthew 28:5-6
The angel [at Jesus's tomb] 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.
Also, Matthew 28:11-15 claims that the chief priests bribed the guards at Jesus's tomb to say the disciples stole His body. Now, keep in mind that this was written 30-some years after the events, so it's likely countering claims the Jews made.
If Jesus's body was still in the tomb, the conversation would have gone something like this.
Disciples: Jesus has risen!
Jews: You're crazy, his body is still in the tomb!
However, if the body was indeed missing, it probably would have looked more like this:
Disciples: Jesus has risen!
Jews: You stole his body out from the tomb while the guards were sleeping!
Disciples: No, the Pharisees bribed the guards to keep them silent.
The historical claim is also invalidated by the fact that passages have implied poetic meaning, such as a character's name relating to their role in the story, severak stories being based off cultural practices/tradition of the time, and certain aspects of the stories conveniently suiting the intention of the writer.
The stories might be geared towards the point the writer is trying to make, but does that invalidate anything?
Let's say you were to write a book on Lincoln the lawyer. For this book, you'd have to leave out childhood stories like him running across town to return a customer's change, and wouldn't really touch on his involvement in the civil war, but you'd write a chapter or more on the Gettysburg address. The stories you'd include would definitely suit the portrayal you're trying to make, but that wouldn't make them any less true.
In fact the number one contemporary biblical scholar, Bart Ehrman, rejects that there historical evidence of the ressurrection, and he began his investigation as a believing Catholic, and lost belief (in at least that there is historical evidence of the ressurrection) based on his findings. He has learned all the necessary languages, such as Greek, Aramaic etc. and has read every source pertaining to Christianity in the first 500 years following the death of Jesus.
I could give you examples of Christians whose faith has been strengthened by historical studies, or even atheists who have become Christians by these studies, so it goes both ways.
Barabarus means "son of God", and the whole story with him being chosen over Jesus remembles a Jewish tradition where they would choose between two goats, the one set free would be evil, and the blood of the one sacrificed would save the people or something like that.
I think you've got misinformation, I've never heard of that. Can you give me an Old Testament reference of such a law? Also, according to my NIV Bible, Barabbas means "son of Abba", or "son of father" (although the online dictionary mentions that abba was sometimes used to describe God, it likely refers to earthly fathers as well).
I know of another example where some guy is a messenger, and his name means "to tell".
There are plenty more examples in the Bible. The stories do not mention God giving these people thier names.
Actually, God is involved in the naming of quite a few people in the Bible. (Adam of course, Samson, John the Baptist, the previously mentioned Abraham and Peter, and that's only off the top of my head.) Without knowing the examples you have in mind I can't say for sure whether God was involved in the naming or if it was a coincidence though.
Also, the nature of Lazarus changes from gospel to gospel. In the earliest gospel (is that Luke?) he is purely mentioned as a character in a fictional parable. Later on in John, he is mentioned as a historical figure who was at many significant events in Jesus' life, despite the fact it is never mentioned in the other gospels that Lazarus attended those events.
Obviously they're two different people. I'm not sure why Jesus chose to give the name Lazarus to the character in the parable (interestingly, according to my NIV translation it's the only actual named character in a parable.)
Also, John has a rather unique portrayal on Jesus's life compared to the other gospels, and touches on entirely different themes. (Mark focuses on his miracles and impact, Matthew on his sermons, Luke on his parables, but John on his identity as the Son of God.)
I'm glad you asked.
We have historical evidence from 106 AD that Rome was considered the authority, and that it was a heresy not to believe the eucharist physically became the body of Christ.
Hold it right there. It wasn't until Constantine that Christianity was actually an official religion of the Roman empire, and before Constantine it was persecuted.
The two main persecutions were late 1st century under Nero, and the reigns of the two emperors before Constantine, but there was also plenty of local persecution going around in between then. You are not telling me that in between those two periods that it was heresy NOT to be a Christian. That just doesn't make sense.
Secondly, once again you guys attack Catholicism instead of my point, that is that even if Catholicism is illegitimate, then Protestantism is too.
Actually, the main point I'm trying to make is that Protestantism relies on the early church, which is not equal to the Catholic church. And some of that does include attacking the catholic church to show where it deviates from Jesus's teachings.
It's as if all you Protestants have been taught is to attack Catholicism, rather than positively validate your beliefs independantly of Catholicism.
I do try to positively validate my beliefs without referring to the catholic church (see about 90% of the new testament thread and the intelligent design thread), but there are some issues (like the crusades and such, which people love to bring up to attack Christianity on moral grounds) that directly involve the catholic church and just have to be addressed.
