According to Meg Sullivan, regarding the research of UCLA professor Henry Ansgar Kelly into the Biblical figure Satan
He’s not the enemy of God, his name really isn’t Lucifer and he isn’t even evil. And as far as leading Adam and Eve astray, that was a bad rap stemming from a case of mistaken identity.
“There’s little or no evidence in the Bible for most of the characteristics and deeds commonly attributed to Satan,” […]
“A strict reading of the Bible shows Satan to be less like Darth Vader and more and more like an overzealous prosecutor,” said Kelly […] “He’s not so much the proud and angry figure who turns away from God as [he is] a Joseph McCarthy or J. Edgar Hoover. Satan’s basic intention is to uncover wrongdoing and treachery, however overzealous and unscrupulous the means. But he’s still part of God’s administration.”
“Jesus doesn’t like him, and Paul doesn’t like him,” Kelly explained. “He represents the old guard in the heavenly bureaucracy, and everyone longs for him to be disbarred as the chief accuser of humankind.”
