Cofty - Thanks for uploading the video of Prof Bart Erhman. I found it very educational and i learned a lot, although my conclusions might be different from yours. Here are my thoughts:
1) There are 30,000+ differences among the 5,700 manuscripts currently available, majority of them insignificant and don't really matter as they don't change the essence of the message, but rather 'accidental' mistakes
2) Comparing all those manuscripts, you find both 'accidental' mistakes (i.e., spelling) and 'deliberate' additions/omissions in the texts. Both has been identified, and the text re-adjusted to represent possibly the more accurate translation if compared to the original which no longer exist. For example, he mentioned about one verse in Mark's gospel quoting Isaiah the prophet, although it was later found that the quote actually came from Exodus, and not from Isaiah. And so, it was not adjusted, by just saying coming from the prophets, to make it more accurate. Did it come from Isaiah? Maybe not. One of the prophets? More likely so. Problem solved. Did it changed the essence of the story? Not really. This shows that the abundance of the manuscripts, though filled with differences, helps to refine the text to probably match the original form.
3) One of the major differences (note he did not say errors and/or untrustworthiness) of the manuscripts is about Mary saying 'your father and i' changed to 'we' or 'Joseph and I'. Did this change the whole essence of the bible? I can't see the issue here. Whatever the original is, whether the former or the latter, it doesn't change the whole essense of the narrative. Let us not lose the forest from the trees.
4) The prostitute story, including the 8 verses in Mark's account are found to be an addition in later manuscripts. That's good news. Again, it's a refinement we should be thankful about.
5) I do not see any problem in the crucifixion story. If Mark seems to indicate Jesus was pretty quiet during the whole process, but Luke mentioned a few more details, again, it doesn't invalidate that the crucifixion occured. The important thing is, it happened. Jesus died, gave his life for us to have everlasting life (including our friend Prof Bart), now whether he was saying nothing, or said a few words in the process, it doesn't matter. The important thing in the narrative is his actual death. That's the whole essence of the Messiah. For him to die so we can live. That's it. The same thing with the women who saw him resurrected. Whether one woman, or two women saw him, it doesn't matter, the important thing is, he was resurrected.
Sorry, but i do not see any reason why Prof Bart's arguments can invalidate the whole theme of the bible as a complete, solid whole, including, the importance of the ransom by Jesus Christ.
By the way, is Prof Bart Jewish by any chance?
