Excerpt from Bart Ehrman on his blog:
In my previous post I began to discuss Craig Evan’s essay “Getting the Burial Traditions and Evidences Right,” which was his attempt to show that the views I set forth in How Jesus Became God were flawed. In his view, the New Testament portrayal of Jesus’ burial is almost certainly historical: Jesus really was buried, in a known tomb, on the afternoon of his death, immediately after he expired, by Joseph of Arimathea, a member of the Jewish Sanhedrin who had, the night before, called for his execution.
My view is that this is entirely unlikely, that Jesus was probably left on his cross to suffer the ravages of time and, possibly, scavenging animals, as was the practice of Romans for crucified victims. In no instance was this practice more constant than in the case of “enemies of the state,” anyone, for example, who was involved in an insurrection or who threatened a violent opposition to Roman rule (or was thought to have threatened). Jesus himself, of course, was executed on just this charge, of planning to supplant the Roman governorship of Judea in order to set himself up as king.
