Perhaps most surprising is not the figure Satan cuts, but his notable absences in the Old Testament. In the Bible's first reference to Lucifer, for instance, Satan doesn't appear _ even by implication, Kelly points out. "'Lucifer' is Latin for light-bearer," he said, and was the name given to the morning star, or the planet Venus. Originally written in ancient Hebrew, the passage, on face value, refers to the tyrannical Babylonian king who boasts of his conquests but who is "about to be cast to the ground." Kelly insists there's nothing more to the reference than an apt use of metaphor, but the third-century Christian philosopher Origen of Alexandria argued in his best known work, "On First Things," that the reference applied to Satan.
"His job is to test people's virtue and to report their failures," Kelly said.
