Simone Weil (https://www.encyclopedia.com/people/philosophy-and-religion/philosophy-biographies/simone-weil#citationTrigger-437202) was a neo-Cathar (http://www.newadvent.org/cathen/01267e.htm) whom John XXIII ("Oh yes, I love this soul!" (https://books.google.com/books?id=B1NOn1byLnEC&pg=PR12#q="O%20yes,%20I%20love%20this%20soul")) and Paul VI both considered important influences in their intellectual
deformation.
Year of Three Popes p. 2 (https://archive.org/details/yearofthreepopes00hebb/page/2):
QuoteHe [Paul VI] was theologically [de]formed by reading [Liberal] Maritain, [ecumaniac/Protestant] Congar, and [nature≡grace] de Lubac, and intellectually [de]formed by [Jansenist] Pascal, [novelist] Bernanos (https://isidore.co/misc/Res%20pro%20Deo/Sel%20de%20la%20Terre/Sdt%20N%C2%B0007/Georges%20Bernanos,%20romancier%20de%20la%20vie%20mystique.pdf), and [Jew-neo-Cathar] Simone Weil.
Weil wrote a letter circa 1940 in which "she spoke of her admiration for the Catharist (http://www.newadvent.org/cathen/01267e.htm) movement and used the word adherence as opposed to curiosity" (Joseph Marie Perrin, O.P.,
Simone Weil As We Knew Her (https://isidore.co/calibre/#panel=book_details&book_id=7109) pt. 1, ch. 6, fn. 2).
Like the Cathars (http://www.newadvent.org/cathen/01267e.htm), Weil
- rejected the Old Testament, (Cathars rejected the Old Testament in part because they thought the material world and marriage, cf. Gen. 1:28: "be fruitful and multiply", are evil.)
- was a dualist, (cf. #1 above.)
- was a revolutionary, anarchist, and Trotskyite, (Cathars were also revolutionaries, being against oaths, the bedrock of feudalism and medieval society.)
- starved herself to death, a "virtuous" act Albigenses/Cathars called the endura (http://www.newadvent.org/cathen/01267e.htm#B).
During this octave of the feast of St. Dominic, may he intercede for the extirpation from the Church of Modernism—the synthesis of all heresies, including those of the neo-Cathars and Albigensians!
