A recent NY Times article talks about a stone that was found that talks about the resurrection idea in Christianity.
See New Testament scholar, Ben Witherington's, initial response to this here.
Here is a bit of it...."Long story short-- this stone certainly does not demonstrate that the Gospel passion stories are created on the basis of this stone text, which appears to be a Dead Sea text. For one thing the text is hard to read at crucial junctures, and it is not absolutely clear it is talking about a risen messiah. BUT what it does do is make plausible that Jesus could have said some of the things credited to him in Mk. 8.31, 9,31, and 10.33-34."
