VATICAN CITY (AP) — The umbrella group of Catholic religious orders in France is demanding church authorities assume responsibility for horrific evidence of sexual, spiritual and psychological abuse in L’Arche, once a preeminent lay community dedicated to people with developmental disabilities.

Sister Veronique Margron, president of the conference of religious orders in France, issued a devastating analysis Thursday of the implications of the findings of a two-year investigation into L’Arche, its founder, Jean Vanier, and his spiritual guru, the Rev. Thomas Phillipe.

The 437-page report, published on Jan. 30, offers a detailed forensic study of how Vanier created a secretive “sect” within the heart of the Catholic Church designed entirely to feed his sexual appetites through “collective delirium” and mystical-sexual practices that he justified on spiritual grounds.

Using seduction, manipulation, secrecy and coercion, the charismatic Vanier initiated as many as 25 young women into the “mystico-sexual practices” of the sect within L’Arche, convincing them of his sanctity while abusing them sexually and spiritually, the report found.

In a statement on Thursday, Margron said the report prompted questions about the Catholic Church’s “entire ecclesial, theological and pastoral culture, since it has been the breeding ground for abuse, manipulation, aggression, lies and even death.”

She said the report also laid bare how secrecy, and “the great silence” by the Vatican had enabled the “gnostic delusions” of Vanier and Philippe, as well as their impunity and abuse.

Philippe, who was subjected to a canonical trial for abuse and false mysticism in the 1950s, died in 1993. Varnier died in 2019; the following year, L’Arche came out with a preliminary report detailing the abuses he committed as founder of L’Arche.

The organization commissioned the more ample report from six researchers in different disciplines — history, sociology, psychiatry, psychoanalysis and theology. They conducted 119 interviews and had access to church archives, including from the then Holy Office investigation into Philippe.

The findings are the latest to document cases of sexual and spiritual abuse of adult women by priests or charismatic lay leaders, which the Vatican has long dismissed as mere “boundary violations” by otherwise chaste men.

Recently, in an interview with The Associated Press, Pope Francis acknowledged how women can be abused by these “seducing” personalities who manipulate their victims on spiritual grounds to take advantage of them sexually.
