Someone stole the body!

[Angrboda]

Even so, it is often said in objection that we can trust the Gospels more than we normally would because they were based on the reports of eye-witnesses of the event who were willing to die for their belief in the physical resurrection, for surely no one would die for a lie. To quote a Christian website: "the first disciples were willing to suffer and die for their faith...for their claims to have seen Jesus...risen bodily from the dead." Of course, the Gospel of Matthew 28:17 actually claims that some eye-witnesses didn't believe what they saw and might not have become Christians, which suggests the experience was not so convincing after all. But there are two other key reasons why this argument sounds great in sermons but doesn't hold water under rational scrutiny.

First, it is based on nothing in the New Testament itself, or on any reliable evidence of any kind. None of the Gospels or Epistles mention anyone dying for their belief in the "physical" resurrection of Jesus. The only martyrdoms recorded in the New Testament are, first, the stoning of Stephen in the Book of Acts. But Stephen was not a witness. He was a later convert. So if he died for anything, he died for hearsay alone. But even in Acts the story has it that he was not killed for what he believed, but for some trumped up false charge, and by a mob, whom he could not have escaped even if he had recanted. So his death does not prove anything in that respect. Moreover, in his last breaths, we are told, he says nothing about dying for any belief in the physical resurrection of Jesus, but mentions only his belief that Jesus was the messiah, and was at that moment in heaven.[17] And then he sees Jesus--yet no one else does, so this was clearly a vision, not a physical appearance, and there is no good reason to believe earlier appearances were any different.

The second and only other "martyr" recorded in Acts is the execution of the Apostle James, but we are not told anything about why he was killed or whether recanting would have saved him, or what he thought he died for.[18] In fact, we have one independent account in the Jewish history of Josephus, of the stoning of a certain "James the brother of Jesus" in 62 A.D., possibly but not necessarily the very same James, and in that account he is stoned for breaking the Jewish law, which recanting would not escape, and in the account of the late 2nd century Christian hagiographer Hegesippus, as reported by Eusebius, he dies not for his belief in a physical resurrection, but, just like Stephen, solely for proclaiming Jesus the messiah, who was at that moment in heaven.[19]

Yet that is the last record of any martyrdom we have until the 2nd century. Then we start to hear about some unnamed Christians burned for arson by Nero in 64 A.D.,[20] but we do not know if any eye-witnesses were included in that group--and even if we did it would not matter, for they were killed on a false charge of arson, not for refusing to deny belief in a physical resurrection. So even if they had recanted, it would not have saved them, and therefore their deaths also do not prove anything, especially since such persecution was so rare and unpredictable in that century. We also do not even know what it was they believed--after all, Stephen and James did not appear to regard the physical resurrection as an essential component of their belief. It is not what they died for.

As far as we can tell, apart from perhaps James, no one knew what the fate was of any of the original eye-witnesses. People were even unclear about who the original eye-witnesses were. There were a variety of legends circulating centuries later about their travels and deaths, but it is clear from our earliest sources that no one knew for certain.[21] There was only one notable exception: the martyrdom of Peter. This we do not hear about until two or three generations after the event, and it is told in only one place: the Gnostic Acts of Peter, which was rejected as a false document by many Christians of the day. But even if this account is true, it claims that Peter was executed for political meddling and not for his beliefs. Even more important, it states that Peter believed Jesus was resurrected as a spirit, not in the flesh...

So what we have are secondary accounts of people who may or may not have been allowed to recant what they believed on the basis of hearsay. That's not a strong testimonial at all.
