the Russian orthodox would call her a fool for christ...a saintly fool...in Orthodox tradition this is not an insult...(see Catherine doherty's books)
Interesting suggesiton - she does have some characteristics in common with the holy women of the Orthodox tradition - a lay person who lived a type of mystic life, and a person set apart from ordinary standards (thus, a "holy fool").
Some aspects of her life remind me of another mystic thinker of the 1930s and 40s - Simone Weil. Alas, they have one negative thing in common, they both seem to have a form of anorexia.
