Yep, that's about the size of it, MrB! Excellent insight!!!
Of course, today even many Christians seem to believe that Satan does not exist; that he's just some kind of fairy tale character that human beings constructed in the past in order to project their own moral guilt onto a cause beyond their control. E.g., "The Devil made me do it!!!"
Which is not to take Satan seriously at all as really functioning within human reality. And which leads to the perspective of "beyond good and evil" typified by Ivan (not to mention the Grand Inquisitor) in The Brothers Karamazov....
Yet for me, the truth of the matter was summed up long ago by an author whose name I do not now recall. (Jeepers, it might even have been Dostoveysky, but I don't have a cite.) The main insight there was (paraphrasing):
"I am Satan, the Father of Lies. And the greatest lie I ever told — and got mankind to believe — is that I do not exist."Just some miscellaneous food for thought!
Thank you so very much, MrB, for getting us focused on your splendid tagline!
