The Eudist Family is a big network of congregations and lay groups living the spiritual heritage of St. John Eudes.  It includes the two congregations he founded directly and a host of other congregations that count him as their spiritual father.  Here are some of them:

The Institute of the Sisters of Our Lady of Charity was founded by St. John Eudes, in 1641 in Caen, France.  Their primary Apostolate is to work with “women in need.” Today their ministries include: counseling, serving in parishes, counseling troubled teenage girls, day care for children and adults, rehabilitation and nursing care for the ill and elderly, people with AIDS, teaching in schools and religious education programs.

The Congregation of Our Lady of Charity of the Good Shepherd (also known as Religious of the Good Shepherd or Good Shepherd Sisters) is an international congregation of religious women in the Roman Catholic Church, numbering almost 4,000, present in 70 countries in five continents.  As religious they are called to a mission of reconciliation, “we express our charism of merciful love through a contemplative life or an apostolic life.” (Constitutions, Article 1)

Their service traditionally and currently is with women and children who have been wounded by life’s circumstances and live on the edge of society.  They accompany those who are in need and also network with other groups to change unjust structures in society.

The Little Sisters of the Poor is a Roman Catholic religious order for women. It was founded in the 19th century by Saint Jeanne Jugan near Rennes, France.  Jugan felt the need to care for the many impoverished elderly who lined the streets of French towns and cities.

This led her to welcome an elderly lady into her home and the work of the Little Sisters of the Poor began. Gradually Jeanne Jugan built up homes in and around Rennes.  In 1843 the community's spiritual advisor declined to let Jugan head the order and so she became an ordinary sister and model of humility. Jeanne Jugan was a helper to the elderly and disabled.  She used to go on the streets of France to collect money for her organisation. Once when Jugan begged a young man for money, he hit her on the face.  She replied with calmness, "You gave that to me, now give me something for the elderly."  The man was astounded by the sweetness of her reply and with all his heart he gave her all the money he had at that time.

Today the Little Sisters of the Poor serve in 31 countries around the world (including homes in Hong Kong, Taiwan, India, Penang, New Zealand and Philippines) continue in their original purpose of caring for the elderly. In addition to the Sisters' apostolate, a semi-contemplative emphasis is also maintained within the order. Professed sisters therefore take a new religious name - usually a saint or someone associated with the order, and wear a full religious habit consisting of a black dress and scapular, full grey veil and a white headband which covers the hair of the sister. In warmer climates/seasons a white habit/veil is worn by the sisters. They have grown from one woman helping one woman to one of the most successful religious organizations in the world.

The Eudist Servants Of The Eleventh Hour is a new branch, a twig sprouting on the 400 year-old tree of the extended spiritual family of St. John Eudes.  This is an association of the faithful whose members are sisters who are mature women who love Jesus and want to follow Him by serving the poor and the needy. The Eleventh Hour refers to the scripture where Jesus calls the last, and signifies that the community is for older women, generally between the ages of forty five and sixty five.  The community's mission is to minister to the poor and the needy, to bring to them the love of Jesus Christ.  To accomplish this members must, in their hearts and in their lives, bear the pain of the poor, the imprisoned, the sick, the rejected, the forgotten and the abandoned children of God.  Members of the community serve, with the permission of the local Bishop, in a variety of locations in Mexico and the United States, and perform a variety of services. Mother Antonia Brenner, the Servants' founder and current superior of the community, serves by ministering to prisoners and guards at a prison in Tijuana, Mexico.  Several other sisters work alongside her in Tijuana. Sister Kathleen serves her ministry in Baton Rouge and Lafayette, Louisiana as a prison chaplain. Still another Servant, Sister Lillian, serves in her home area of Texas, tending to the elderly in nursing homes.

The Servants operate a ministry center, Casa Campos de San Miguel, located just three blocks from the La Mesa penitentiary. The Casa is a refuge for women leaving prison and for women visiting incarcerated family in the nearby prison, and also for women and children who have come to Tijuana for treatment for cancer.  The sisters also have a convent nearby, Corazon de Maria, which serves as the community headquarters and is also a residence for some of the sisters in Tijuana.  Corazon de Maria is also used as the community’s house of formation.  Still other sisters and associates live in the United States and commute daily to Tijuana to visit area hospitals and comfort patients and their families.

All of the sisters are self-supporting, both economically and with their own health care. Vows are taken for a one year period and then renewed annually, if mutually agreeable.
