Mont Saint Michel and Chartres (1904)
Context: No one has ventured to explain why the Virgin wielded exclusive power over poor and rich, sinners and saints alike. Why were all the Protestant churches cold failures without her help? Why could not the Holy Ghost,— the spirit of Love and Grace,— equally answer their prayers? Why was the Son powerless? Why was Chartres Cathedral — like Lourdes today — the expression of what is in substance a separate religion? Why did the gentle and gracious Virgin Mother so exasperate the Pilgrim Father? Why was the Woman struck out of the Church and ignored in the State? These questions are not antiquarian or trifling in historical value; they tug at the very heart-strings of all that makes whatever order is in the cosmos. If a Unity exists, in which and towards which all energies centre, it must explain and include Duality, Diversity, Infinity,— Sex!

“You can be a virgin in horror the same as in sex.”
