Yesterday, New York Magazine published an interview with U.S. Supreme Court Justice Antonin Scalia, in which is he quoted as saying that he believes "the Devil" has given up taking possession of humans to make them sin, in favor of causing them to be atheists. His reasoning is as follows:
I mean, c’mon, that’s the explanation for why there’s not demonic possession all over the place. That always puzzled me. What happened to the Devil, you know? He used to be all over the place. He used to be all over the New Testament.
So, to him, I guess, the fact that we don't see demonic possession on a regular basis, yet people are sinning and not believing, proves that The Devil is changing tactics - because in what Christians call the New Testament he is a regular feature. But, as far as I know, there isn't much of an occurrence of "the Devil" in TaNa"Ch, or what Christians refer to as the "Old Testament".
I know what the standard Jewish approach is regarding "the Devil" (short version: he doesn't get a mention, and we don't believe in such a being - at least not in the way commonly talked about by Christian preachers). But according to the Christian view (across most denominations, as far as I can tell), there is some being called "The Devil" who possesses people and causes them to sin, etc. Where is he in what you call the Old Testament, and why would he just suddenly appear later?
