Just to make a quick suggestion,
It's over a decade old, but I just read The Origin of Satan by Elaine Pagels, and it does a wonderful job of looking at the hundred years or so after Jesus' life (yes, she assumes the existance of a specific, historical Jesus, but the canonical writers of the time seem to have done so as well), and examines it in terms of how Satan is defined and identified with various groups by different authors. It's interesting to see how and why a known sadist like Pilate would be given such a free ride by Gospel authors.
Wow, and here I had assumed we only knew that he was even a real person for just the last 50 years or so, after the Pilate stone was discovered. In fact, his only public mention in history, beyond the Pilate Stone in Caesarea, is the four gospels, and in them he is portrayed
at worst as disinterested in Christ and his fate; in fact, his wife was proclaimed a saint by the church based on one of the gospel's testimony.
Please, what evidence for Pilate's sadism do you (or Ms Pagels) have, really? Philo and Josehus, both, were Jews who could hardly be expected to view Roman rule dispassionately, and they are the only contemporary sources.
Hmmmm. Upon further research I find that perhaps I was being a bit heavy on Dr. Elaine Pagels
WP, if not on you. The citation concerning her book (full title:
The Origin of Satan: How Christians Demonized Jews, Pagans, and Heretics) doesn't even mention Pilate; primarily it is an explanation about how the church managed to villify Jews and heretics, just as the whole title suggests. Also, I assume that includes the way they sidelined gnostics, since that appears to be her major field; gnosticism is at the root of many of the early heresies. Personally, while I am somewhat thankful that gnosticism's reliance on special messages and the elect weren't part of the early church, perhaps that would have weakened it later and not left us with the confusing legacy we now have. The means by which it was done, though, was wretched and cruel, and I must insist, typical.
I was also wrong in stating "the only public mention in history". He is mentioned in both Philo and Josephus, contemporary Jewish writers, and that is all.
Nevertheless, villifying Pilate for no good reason is just not useful, and without proof I don't think its useful to even bring up here.
