"In the last years of her life she worried that all beliefs, even religious ones, risk idolatry. Her insistence upon "a convention ratified by God" is another example of the thoroughly personal knowledge of God that she sought, and one gathers, believed herself to have attained. She seemed persuaded that under the auspices of the Church such personal knowledge simply does not come about; on the contrary, parishioners turn idolatrous and mistake a ritual, a habit, and alas, a social custom (to go to church on Sunday, say) for such a convention."
