Here’s a lengthy and substantive post from Eric Chabot on the reliability of the resurrection of Christ. It includes this quote from N. T. Wright:
“If nothing happened to the body of Jesus, I cannot see why any of his explicit or implicit claims should be regarded as true. What is more, I cannot as a historian, see why anyone would have continued to belong to his movement and to regard him as the Messiah. There were several other Messianic or quasi-Messianic movements within a hundred years either side of Jesus. Routinely, they ended with the leader being killed by authorities, or by a rival group. If your Messiah is killed, you conclude that he was not the Messiah. Some of those movements continued to exist; where they did, they took a new leader from the same family (But note: Nobody ever said that James, the brother of Jesus, was the Messiah.) Such groups did not go around saying that their Messiah had been raised from the dead. What is more, I cannot make sense of the whole picture, historically or theologically, unless they were telling the truth.”
