I’m not sure about the legal position here.
The person who would theoretically have to excommunicate her would be her bishop. The problem is that she’s sort of a hot potato.
She claims she’s under Cdl. Archbishop Wuerl, the famous pro-abortion, pro-gay bishop of DC. But she lives in San Francisco for electoral purposes, so her bishop would be Cordileone, who is definitely anti-abortion, anti-gay norming, and anti-everything-Nancy-bloviates-about.
I hope either that Cordileone will get empowered and do what he should do, or that the Vatican will simply override Wuerl (as they did with the bishop in Australia) and slap her with an excommunication. It might make her think, but if it doesn’t, obviously the warm and fuzzy non-confrontational approach isn’t working either. So maybe she’s just on her way to “the other place.”
The only way that could change is when and if, Cardinal Wuerl makes the decision to hand his paper in to retire. The next archbishop could very well be very much conservative.
I think you’re right.
