Not sure if you still want to engage Kaleb but regarding the evolution of the Devil/Satan figure, your objection to my comment seems to be in the suggestion that some Jewish circles had included a rebellious angel element in the concept. I'm not as fully read on the topic as I'd like but the Enochic tradition certainly included the idea of rebellious angels and a leader called Satanail, and the Tobit story with its Ashmedai prince of the demons sound very much like the Devil figure in the NT. The Ezekiel 28 Protective cherub that became wicked and the falling star of Isaiah 14 were connected in late nonrabbinic Judaism. Again, I go back to the Gospel and Revelation themselves, the descriptions of the Devil within are not presented as if a new revelation, the readers are assumed to be aware of the characters, it's the action that is the focus. Paul's (and G,John's) use of archon suggests some connection to early Gnostic ideation. That really is not controversial. I think it demonstrates the composite character of the tradition of Satan. I hesitated to include the Jewish Mysticism traditions but they often featured the 'Samael' Great Demon as a live character of rebellion. Probably only secondarily connected but in some Gnostic traditions the Devil was actually an earlier son of God than Christ. The whole idea of losing great position and rank by rebellion runs through much of these traditions.
Specifically what part of my comments are incorrect? I post some speculative stuff to be sure, but it is always with the motive of brainstorming with more experienced posters. Be free to respond to error without concern for my feelings. I consider myself lucky to have had your ear.
