I never realized she has a liberal theological axe to grind. I haven't paid her too much attention, but I always just thought, how nice to have a nun talk about the history of religious art.
I'm not as critical of her. I AM a little suspicious when PBS and USA Today fall all over themselves to interview her on theology. She doesn't come across as evangelical Catholic, although I can't say as if I've heard apostacy or heresy from her.
I guess I prefer to hear theology from Pope Benedict, though.
