Well, thanks to Igloo for backing me up here. In answer to Curt, I didn't reply before because of the vagaries of my rather erratic hours at work.
Apologies in advance for this massive essay of a post, but Curt seems to be unsatisfied with the evidence presented so far, and this might keep him quiet for a bit! ;-)
OK. I think that this is where Curt and I agree and where we disagree.
We both agree that Christianity is bascially untrue, and that not everything in the Bible is true. I studied Marks Gospel in great detail at university and came out of it thinking that the expression Gospel truth is rather ironic. The Bible is full of myth, legend, and distortion. That is something that any liberal Christian would agree with, as well as anyone who studies the Bible from a secular point of view, as I did.
But we disagree over the extent of the Bibles untruth, and in particular over the reliability of the text. When I say reliability I mean not the texts veracity whether or not it describes things that actually happened but whether or not the text has been changed over the centuries. Curt says it has, and hints at vast numbers of substantial changes designed to reinforce the dogma and social power of the priesthood. But he gives no evidence, beyond the assumption that this is what Christians would naturally do. I say it hasnt much and have already given some evidence. Curt, despite refusing to address the evidence that I and others have already given, challenges me to provide more. Here is some. Apologies again for the detail, but the study of ancient texts is never a very user-friendly discipline. Trust me, the serious academic stuff on this is far, far denser.
Two of the most of important manuscripts of the Bible are the Codex Vaticanus and the Codex Sinaiticus. These are by no means the only sources for our knowledge of the text, but are two of the oldest and the most famous.
The Codex Vaticanus contains a complete text of the Bible the Septuagint version of the Old Testament (a Greek translation used by the early Christians) and the whole of the New Testament, except for some of the books at the end, which are missing. The manuscript has been kept at the Vatican since at least the fifteenth century, but where it was before this is unknown. Orthographic experts date it to the fourth century AD on the basis of the script in which it is written, as well, of course, as a study of the materials of which it is made.
The Codex Sinaiticus was discovered in 1859 at a monastery at Mt Sinai. It contains the whole of the New Testament, much of the Septuagint version of the Old Testament, and also a couple of other works that, when it was written, were sometimes considered part of the New Testament. It is also thought to date from the fourth century, a little later than the Codex Vaticanus. Where it was before 1859 is unknown, although inscriptions on it indicate that it was probably in Palestine in the sixth or seventh centuries. The Codex Sinaiticus is currently housed in the British Library, where I have seen it with my own eyes.
The text of both of these ancient manuscripts is pretty much that of the Bible as we know it. If Curt is correct, there are therefore two possibilities. The first is that these manuscripts are not nearly as old as they are usually thought to be. In fact, they must be modern, or at least post-date the most recent amendations to the Biblical text that those unscrupulous Christians carried out. The second possibility is that the manuscripts are indeed from the fourth century, but the text they contain is not, in fact, that of the Bible as we know it.
The second possibility cant be true. We would have to believe that every scholar who has ever studied these manuscripts has agreed to participate in a massive conspiracy to cover up what they really contain. Perhaps that might, in theory, be true of the Codex Vaticanus, which is after all in the Vatican library. But I dont think it can be true of the Codex Sinaiticus, which is in the British Library and therefore out of the control of any ecclesiastical authority. The scholars who have studied these texts are not all religious. In fact, I should think that these days most of them are not. I myself have looked at the Codex Sinaiticus and, while I certainly havent read all of it, I can testify (even with my rusty Greek) that the bits I have seen appear to match the Bible as we know it today. This book is publicly available to anyone who wishes to read it. In fact, you can see a page of it for yourself at

Could these manuscripts actually be much more recent than has always been thought? They are thought to be from the fourth century, but if Curt is correct then they must be MUCH later. Experts may argue over whether something is dated to the fourth century or the fifth, but they can tell the difference between a fourth-century manuscript and a fourtheenth-century one. As far as I know, nobody has argued that these manuscripts or any other important textual witnesses to the Bible are modern. If they had, it would have been headline news. Remember the fuss over the Turin Shroud when it was shown to be a forgery. Think of the controversies currently raging over the St James ossuary. Thats the sort of thing that happens when people argue that such things are inauthentic. These Biblical manuscripts are far more important than the shroud or the ossuary. If the Turin Shroud is a fake, that doesnt mean that Christianity is false. If scholars and theologians have been lying about the manuscript tradition of the Bible, it would cast huge doubt over Christianity. If Curt is right, there is a massive, massive scandal waiting to break, yet no scholar or expert, even the many atheist ones, seems to have broken it. Either that or I just havent been paying enough attention to the news recently. As Amenhotep7 rightly points out, we're getting into ridiculous conspiracy theory territory here.
And Curt claims not to believe in miracles? Cest drôle, nest-ce pas?
All of this is not to say that there are no discrepancies between manuscripts, or that there is no uncertainty over the text. Certainly there are variations, and some of these are highlighted on the Codex Sinaiticus page that I linked to earlier. For example, different traditions give different endings to Marks Gospel. John 8:1-11 (the story of the woman caught in adultery) is missing from many manuscripts, and in any case doesnt seem to fit in with the flow of the story. But these are relatively minor matters. They dont indicate massive tampering with the text. They indicate a few mistakes along the way, slightly variant traditions. As far as I know, the only textual variation that speaks of deliberate tampering on doctrinal grounds is 1 John 5:7, which teaches a doctrine of the Trinity much more advanced than any in the rest of the New Testament. The verse in question appears in only some manuscripts and is universally recognised as an interpolation from some centuries later. So there is some evidence for the sort of thing that Curt talks about, but it is far less extensive than he insists.
Now consider this. The Biblical texts of all Christian churches today are the same, apart from the minor differences in that of, say, the Jehovahs Witnesses. The Bible used by the hermits of Siberia is the same as that of the Nestorian Church of the East; the Bible of the Pope is the same as that of Billy Graham; the Bible of the Korean Church is the same as that of the Patriarch of Constantinople. Different churches disagree on which books count as Scripture (Protestants reject some of the books that the Catholics include) but they do not appear to differ on what those books say. If Curt is right, then all of these different churches must have collaborated to change all their texts in the same ways at the same times. So, for example, if the Pope decided in the thirteenth century to add a miracle story somewhere, hed have had to have got together with the leaders of the Nestorian and Monophysite churches, the Orthodox Church, the Armenian and Ethiopian churches, and the rest. But obviously this is ridiculous. After the sixth or seventh centuries, the Catholic and Orthodox churches couldnt even speak each others languages, let alone collaborate on textual corruption. The Ethiopian church was almost completely out of touch with the rest of the Christian world for a thousand years. In the Middle Ages, the Catholic and Orthodox churches excommunicated each other and even spent some time at war. The Church of the East was excommunicated by the Orthodox Church in the fifth century. These people did NOT get on very well even when they were in touch. Therefore, Curt is wrong to imagine Christians in the Middle Ages altering the Bible at will. Any amendations must have happened extremely early - before the fifth century, at least, when the Nestorian and Monophysite churches split away from the Orthodox.
To put this point another way, many of us here, Curt included, talk about "the Christians" an awful lot. "The Christians" did this, "the Christians" did that. Which Christians? The ones in Rome? In Constantinople? In Kiev? In Nisibis? In Aksum? These people all believed different things from each other. Half the time they weren't in contact, and the other half they were denouncing each other. Perhaps that's not to the credit of Christianity in general, although you might say the same thing of scientists and still think that science is a worthwhile pursuit. But that's not the point here. The point is that you can't just make blanket statements about what "the Christians" at some unspecified point in history may or may not have done. You have to show some historical sensitivity and provide a bit of context.
Returning to the argument, if you look at the Biblical text you don't see the kinds of things you might expect to, if it had been altered to such a degree by those nefarious and rather shadowy "Christians". For example, the big split in the church in the fifth century that I mentioned above was over how to speak about Jesus' divinity and his humanity. Some people stressed one over the other. And how did they relate to each other? Some people thought of Jesus as a sort of mish-mash crossbreed whilst others thought of him almost as two people, a divine one and a human one, operating in an unlikely committee (these are rather exaggerated descriptions, by the way). The party that "won" was those who said that Jesus is one person with two full natures, human and divine. There was an awful lot of heartache and bitterness over this, and it lasted for some centuries, because the Nestorians and the Monophysites refused to accept the decision. Now, all these people spent most of their time quoting Bible verses at each other in support of their various views. If Curt is right then they should have spent the rest of their time making up Bible verses for this purpose. So it's funny that we don't find a verse in the New Testament that says something like "Jesus then said, 'By the way, in case you're wondering, I am a single person with two natures. I have a full and perfect human nature and a full and perfect divine nature. These two natures do not interfere with each other. However, I am a single person, numerically identical to the second Person of the Trinity. Anyone who says otherwise is definitely a heretic.'"
