Hello,
I, like A2, am an atheist. I think I have been--in the very least I have been sceptical--my entire life. The question he has posed is a completely valid one, and I can't seem to find any relevant or convincing arguments here that answer it.
What I want to know is how you can have so much faith in a Bronze Age superstition. Why aren't you compelled by the Icelandic Sagas to believe in Odin or Thor? About as much writing exists about Zeus, Hera, Heracles as there does about Jesus and Yahweh. So why are you so willing to put your 'faith' in what you were told by humans about a book written by humans? It seems to me it isn't 'god' you have faith in, but other human beings. Why is it so unreasonable for people like A2 and I to demand more than that? To not make decisions based on the words of others with no substantiating proof? I trust verifiable, repeatable, and visible evidence before I trust anything. Historical sources are never deemed completely reliable, but they are always ALWAYS read with that bias in mind.
As to Alexander; yes, the earliest remaining sources describing him and his campaign are hundreds of years after his lifetime. There are many disagreements in the sources about particular events (Ie, if he cut the Gordian knot or if he pulled the holding pin) but there is no doubt in scholarship that he was a real man. That he lived, and that he really did lead a campaign across the Mediterranean. I accept these basic, verifiable facts because--while the sources are not as old as we would like--there are countless accounts. None of them first hand, but they don't have to be. To substantiate his existence we only need one or two sources--separated by great geographical distance--to make an educated assumption that the person in question was real. More importantly, Alexander left behind a legacy and material evidence of his existence--the Hellenistic world was not an illusion-- that is not difficult to verify, and Macedonia did keep a record of their Kings. But it is impossible to make any solid statement of fact about the specifics of his campaign because we simply cannot verify that the testimonies of Plutarch, Quintus, Diodorus, Pliny, Arrian, Cleitarchus, Justin, Valerius, or Aelian (to name only a few) are completely factually accurate. But we aren't making that claim, are we?
The fact that theists struggle to come up with even one such account - Josephus- whose validity is HIGHLY in question, when I can name nine such accounts of Alexander makes them not even in the same arena to be compared. We can prove Alexander existed, and even if you can prove conclusively that Jesus existed, you can't prove anything else about him because the records simply don't exist. We don't claim anything extraordinary or supernatural about Alexander, but you want to claim all kinds of things about Jesus when you can't even verify he was a real man to any satisfiable degree.
I'll try to answer your concerns to the best of my ability. I apologize if my writing is a bit scrambled, but hopefully it will be easy enough to follow. I think it is important to first address the issue of whether or not Jesus actually existed before moving on to the possibility of his divinity. Most scholars would suggest that Josephus' account about Jesus is not reliable but that it was added to at a late date. Many of those same scholars would also admit that it is likely that Josephus had mentioned Jesus, but the bit about miracles and what not was simply added. The reason that claim is made is because it is much more likely that if Christians were to create the entire account from scratch, that it would be much more elaborate rather than simply being a few sentences stuck in. Now, I realize that that probably doesn't sit well with most, but Josephus isn't the only non-Christian historian to give an account of Jesus. Tacitus also made mention of Jesus and his account is considered to be authentic by most all scholars. I've come across a few other non-Christian historians in the 1st century who have mentioned Jesus; however, I can't remember their names off the top of my head. I could find information on them if you like.
Now, it is really better to establish the probability of there being a God of any sort before making the jump to the Christian God, but since that is not what your post has brought up I'll simply address the reasons I find the belief in a supernatural Jesus more probable than any other deity. If you do wish to discus the logic of a God, just message me or start a new thread. What causes the accounts of Jesus to be more believable than accounts of other deities is that the accounts of Jesus' supernatural abilities, and specifically His resurrection, come from multiple sources rather than just one source. I'm going to specifically address the resurrection because if one can be resurrected from the dead, then the other claims should not seem hard to believe. Similarly, if Jesus did not raise from the dead then whether or not Jesus did perform miracles is irrelevant.
There seem to be 3 explanations to these multiple sources of Jesus' resurrection, at least that I'm aware of. 1) The authors knowingly made them up with the intent to deceive others. 2) The authors all believed that Jesus truly did resurrect due to hallucinations, dreams, etc... and wrote their accounts based on their experiences. 3) The authors wrote what they actually observed. I will go on to list the reasons why I think option 3 is the probable option. First, I'll address number 2 simply because it can be addressed with the fewest amount of words. While it is common for people to have hallucinations after the death of a loved one, the probability of multiple people having the same hallucination is close to 0. Also, the descriptions of the visions of the resurrected Jesus vary greatly in detail type when compared to the hallucinations that people typically have. I can go into more detail if you wish but will stop for now simply to save space. Option 1, mentioned above, seems to be the most logical reason for the accounts of the gospel, if they are not true but there are a few reasons that option 1 is not a probable conclusion. One reason is simply that the gospels mention women being the first witnesses of Jesus' resurrection. At that time, a woman's account was not considered reliable and many wouldn't believe a woman's account of a situation for that reason alone. As a result, it wouldn't make sense for disciples to mention women being the first witnesses of Jesus unless it actually happened. Although that idea by itself may not lend an abundance of support for the resurrection of Jesus, I do think that the eventual martyrdom of many of the disciples does provide ample support. I find it hard to believe that the disciples would knowingly spread false information about Jesus' resurrection simply because they were persecuted and eventually killed because of that information. Charles Colson mentions how when everything happened with Watergate, a small group of people couldn't keep a secret when simply faced with jail time. How likely is it then that a group of people would knowingly keep a secret when faced with death? Especially when that secret had no benefit to them.
I expect you'll have numerous objections to the statements I've made thus far so I'll stop and let you respond if you wish to dialogue with me. You could also simply message me if you find that more appealing.
