To respond to the needs of the poor domestic servants, Bishop Eugene had been instrumental in the founding of the Sisters of Compassion in collaboration with Fr. Jean François Barthès, S.J.
I visited the establishment of the new Dames de la Compassion [Sisters of Compassion]. Evidently, the good God is helping this good Father Barthès to make him succeed in some undertakings where the most skilful would fail.
In his diocese he wanted the laity to be fully involved in the various works of mercy, and tried to provide religious to support them, where possible. The founding of the Sisters of Compassion aimed at supporting the ministry to domestics.
Even so, I recommended to him that l’Oeuvre des Domestiques [the Work of the Domestics] be not neglected. It is essentially for this work that I have adopted this new Order or, to say it better, that I have let it develop under my auspices and my authority.
Eugene de Mazenod’s Diary, 29 June 1845, EO XXI
“Arriving in Marseilles in 1843, Jean-François Barthès encountered a community of Sisters of the Holy Family from Bordeaux who had been called to the city by Eugene de Mazenod, Bishop of Marseilles, to care for the sick in their homes and to open a house for young women who had left the country to work as domestic servants. Bishop de Mazenod then thought of creating an autonomous congregation, entirely dedicated to the work of domestic servants, and entrusted the task to Barthès. Barthès created the congregation on June 25, 1843 in Marseilles; it was erected as an institute of diocesan right on June 16, 1845, the same day the first twelve postulants received the religious habit from the bishop.” https://fr.wikipedia.org/wiki/Sœurs_de_Notre-Dame_de_la_Compassion_de_Marseille
