Which presumes that these aspects of the NT story are historical facts: perhaps then you can answer the question that I've asked the likes of Hope numerous times with nary a reply: how have you assessed the risks of mistakes or lies in the NT accounts you seem to be presenting as historical fact?
'nary a reply' suggests that you have ignored those replies - not only from me but from 'the likes of me', Gordon. I know that Jim as posted several very staright-forward responses to such challenges over the years, I have done so too. I think, put simply, one has to consider the likelihood of some of the other possibilities - such as the suggestion that the disciples took the guards on the tomb by surprise and spirited the body away - and decide whether they are any more credible than the story it replaces.
In this particular case, is it likely that a small group of odinary people - as the disciples were - would have been able to overcome a group of Roman soldiers who would have been given instructions to guard against this very possibility (remember that, because he had been crucified, Jesus and his followers would have been deemed a serious threat for some time after the crucifixion). Not only would they have had to overcome the guards, but they would have had to do so in such a way as to ensure that not a single one was in a position to stop them opening the tomb. My experience of trained military suggests that such an event would have been pretty well nil.
Next, the suggestion that Jesus only swooned and revived in the cool of the tomb. The very fact that there was a spear thrust that gave evidence that the blood had already begun to separate would seem to suggest that this, too, was highly unlikely.
What about the 3rd alternative often posed - that Jesus lived and had a family. This would require one or both of the the above to have been true and, as I've already pointed out, the probability for either is so small as to make this option even smaller.
