Further to this suggestion.

Not everyone who was an anti-Republican in 19th Century France was necessarily a member or even a supporter of Le Hiéron du Val d’Or. Did Bérenger Saunière mention the name “Le Hiéron du Val d’Or” ANYWHERE in his writings? Did he correspond with members of Le Hieron du Val d’Or? No evidence has ever been found; except for a lot of wishful thinking hoping that there was such a link.

Not every single individual who was against the French Republic in 19th century France was a member of Le Hiéron du Val d’Or. Not everyone who installed the symbolism of The Sacred Heart in 19th century France was necessarily affiliated with Le Hiéron du Val d’Or. On the other hand, there was a strong following of Bernadette Soubirous and the Shrine of Lourdes. Bernadette Soubirious died in 1879. Shortly afterwards Abbé Bérenger Saunière made his appearance at Rennes-le-Château in 1885. Abbé Saunière installed a statue of Our Lady of Lourdes in 1891.

Rennes-le-Château is approximately 287 km from Lourdes.

Money laundering schemes are frequently designed to operate from a different part of the country – or even a different country – from where the criminal activity and the perpetrators are based. This geographical separation is a core component of layering, the second stage of money laundering, designed to make tracing the illicit funds extremely difficult.

For the record, in the 19th century, “money laundering” wasn't a legal term, but “pious embezzlement” or “political funnelling” from wealthy aristocratic families (who were also major donors to Lourdes) to fund anti-Republican agitators South, Rennes-le-Château would have served as a perfect, remote clearinghouse.

Also for the record, the first person to link Bérenger Saunière with Le Hiéron du Val d’Or was not Christian Doumergue, but Christopher Scargill in 1985. These details were made known on this website long before Christian Doumergue became active as a conspiracy theorist in this subject-matter.

The Shrine of Lourdes, with its church dedicated to the Sacred Heart, and suspected Money-Laundering site based at Rennes-le-Château, makes for a better and more realistic theory than anything to do with Le Hiéron du Val d’Or.

There was considerable overlap between the Hiéron du Val d'Or and Lourdes – the Hiéron du Val d'Or (that some describe as a Catholic esoteric secret society) was devoted to Christ the King, with integrated devotion to the Virgin Mary, into its religious, political, monarchist and anti-masonic agenda. It was a “culturally conservative” right-wing group promoting a catholic right-wing “hermetic freemasonry”. This of course aligned with the reactionary, pro-monarchist views serving as a national rallying point for the conservative Catholics of France. Both the Hiéron and Lourdes fostered a spiritual “resistance” against political modernism.

In any case, the spirituality of the Sacred Heart of Jesus as adopted by Le Hiéron Du Val d'Or was originally inspired by the Visions of Margaret Mary Alacoque (1647-1690), at the convent of Paray-le-Monial, distinctly a different tradition to the Visions of Bernadette Soubirous in Lourdes. Margaret Mary Alacoque was instructed by Jesus to promote a feast on the Friday after Corpus Christi to honor His Sacred Heart, and it's in Paray-le-Monial that the Hiéron Val d'Or became established serving as a major focal point for studying and celebrating the devotion of the Sacred Heart as inspired by her visions, which has served as a pilgrimage site in the memory of Margaret Mary Alacoque, canonized by Pope Benedict XV in 1920.
