Elena Maria Vidal provides a much needed reassessment of Marie Antoinette:
“Hers was a piety that was loving, gentle and courteous, but real and unflinching nevertheless. Antoinette’s approach to faith was joyful and non-judgmental, free from the rigorist approach of Jansenism that so tainted a great deal of French piety in the years preceding the Revolution. Nevertheless, even as a young bride, she had the moral courage to defy the king in regard to Madame du Barry.”
