English translation of above
Diana Vaughan was American by her father and French by her mother.
She belonged to Luciferian Masonry and directed the PALADIC Review.
Diana Vaughan, who evolved in an environment that fought the Catholic Church, however had a Passion: Saint Joan of Arc.
She had trouble conceiving that Saint Joan of Arc had nothing to do with her Luciferian background.
Her Passion for Saint Joan was that she began to pray as Saint Joan did.
Diana Vaughan was also passionate about Mélanie Calvat de la Salette to whom the Blessed Virgin appeared.
Diana abandoned her Masonic and Luciferian background because Saint Joan of Arc was for her "the Shepherd's Staff" that she lacked: she converted to the Catholic Religion of Saint Joan.
And Diana Vaughan will die Young, a Death that could not be more Mysterious.
At the end of the 19th century, it announced terrible events that were going to fall on the Catholic Church.
In 1903, after the death of Leo XIII, the Vatican nearly fell with the Luciferian Pope Rampolla of the Ordo Templis Orientis.
Diana Vaughan, having revealed the Rampolla network, was she the one who prevented these Luciferians from taking over the Vatican?
For Luciferian Masonry has officially failed with its Satanist Rampolla networks; it is Saint Pius X who will be elected Pope.
Dian Vaughan unveiled the Luciferian Calendar in which specific dates, specific months were the Fact of events that happened within the Vatican tipping it over to Vatican II with the heretic Roncalli that will trigger Vatican II, such as the unveiled Diana Vaughan.
The Author of the Book "From La Salette to Diana Vaughan", Paul-Etienne Pierrecourt, explains to us why Diana Vaughan was declared "never to have existed" by Léo Taxil.
In view of All Authentic Records, with the author of the book, it can be said that Diana Vaughan lived well. We understand why, for satanist Luciferians, the existence of Diana Vaughan is disturbing, especially since she is “Dead” most Mysteriously in the World.
