I think Alinsky’s little part about not knowing where history ends and mythology begins was just his way of trying to have it both ways. If he admitted to believing in the story of Lucifer, he would be essentially admitting to being to some extent a Satanist. In so admitting, he would be rejecting the religion of scientific materialism which is central to cultural Marxism.
But at the same time he clearly had an inclination toward Lucifer.
I think that was Alinsky's coded way of saying that Lucifer is real!
Just as Yeshua doesn't want to be denied, neither does Lucifer. Both require an oath of allegiance.
That's how humans commit themselves and their spirits in just about everything they do.
