Is JB meant to be JC?: Prime of Miss Jean Brodie

And now another level of allegory emerges in "The Prime of Miss Jean Brodie," as she begins, half-way through the book or so, as an older woman looking back, to wonder (obsess over) which of her "set" of girls "betrayed" her. Hmm. So we have a figure followed by a devoted set of disciples, who hang on her every word and build their entire lives around what she says, proposes, and does, and one of them betrays her (we do know who but we don't, yet, know how) leading to her ... not crucifixion certainly but to her firing, a kind of death I suppose. I JB a female JC? If so, I would say it's in a perverse way to say the least - she is hardly a figure one would wish to emulate, and I can't see that she is in any way an avatar of Christian principles: she is harsh, cruel, unduly opinionated; she plays favorites. If I'd been a student in her school (of course that would have been a different kind of school) I'd have hated her. But is she good for her girls, her set? Has she advanced them in their lives? Spark doesn't exactly answer, or confront, that question, at least through the first half/two-third of the novel - our glimpses of the later lives of the girls don't show an obvious formative influence, they have become what they might have become without Brodie's intervention, it seems. So what's the point of the allegory? Is it meant to tell us something about Jesus? Or something about the worship of false gods? If Miss Brodie is the God, I'm an atheist.
