As I start this post I'm thinking of an interview with Peter Cundal of Gardening Australia fame where he told a story of how once he asked in Sunday School "If Satan tempted Eve and Satan used to be an angel them who tempted Satan?" he was thrown out of Sunday school for the question and promptly gave up any further thought about Xy.
There's a lot of varied thought about Satan, I wonder if one of the reasons is because there is not too much said about this character. This is true particularly in the Old Testament where the Hebrew word for Satan appears only a handful of times. For the most it part the word is translated as "accuser" (Num 22:22, 1Sa 29:4, 2Sa 19:22, 1Ki 5:4, 1Ki 11:14, 1Ki 11:23, 1Ki 11:25, Psa 109:6) and once as "adversary" Num 22:32.
In Job the character doing the accusing (often called Satan) appears quite a bit in the first two chapters. (Job 1:6, 7,8,9,12, 2:1, 2,3,4,6,7). Job is wisdom literature and I think written to teach us how God views suffering, rather than a historical account of Job's life and as such the writer takes some licence including the possibility of the creation of the accuser character, who unlike how most people would think of Satan, is part of heaven 1:6. The accuser's role is simply to say "Hey, I think Job only likes God when everything is going well for him". Similarly in the only other two places (yes only two) in the Old Testament where "Satan" is mentioned (1Ch 21:1 and Zec 3:1,2). The role of the character is only to accuse and nothing more. This character does not have all the characteristics that we would normally associate with Satan.
If you're thinking "what about Isaiah 14:12-17 where Satan is described as a fallen angel?" That's pretty widely considered a bad interpretation of that passage. See Dennis Bratcher's essay on Isaiah 14:12-17 for more info.
In case you're wondering the "Devil" or "Lucifer" are not mentioned in the Old Testament.
Next month... either sending "Satan" (New Testament) to Hell in a Hand Basket or sending "Hell" to Hell in a Hand Basket or if that gets tricky sending "Hell" (New Testament) to Hell in a Hand Basket.
