St. John Eudes (born November 14, 1601, Ri, near Argentan, France—died August 19, 1680, Caen; canonized 1925; feast day August 19) was the founder of two Roman Catholic religious orders: the Sisters of Our Lady of Charity of the Refuge and the Congregation of Jesus and Mary (C.J.M.; also known as the Eudist Fathers). He was also an important promoter of devotions to the Sacred Heart of Jesus and the Immaculate Heart of Mary, establishing the first feasts in their honor.
Having been educated by the Jesuits at Caen, France, Eudes entered the French Oratory, founded by Cardinal Pierre de Bérulle, and in 1625 he was ordained a priest. A noted orator, he devoted 50 years to the preaching of parish missions in France. Most of his work was centered in Normandy. During several outbreaks of plague in the region, he showed heroic efforts in ministering to the sick and dying. It is said that, to avoid the risk of infecting others, he lived apart from his community in a large cider barrel in a field until this work ended.
In 1641 Eudes established a refuge dedicated to the education and rehabilitation of destitute girls and women who had worked as prostitutes. This work was administered by religious sisters who lived in the refuge with the women they served. In 1666 the order, known as the Sisters of Our Lady of Charity of the Refuge, received approval by Pope Alexander VII. Numerous other refuges were established. (This order eventually developed into the Good Shepherd Sisters.)
In 1643 he founded the Eudist Fathers, a male religious order dedicated to the training of candidates for the priesthood and to the preaching of missions. The concept of seminaries, where priests could receive standardized training, was still relatively new in France. Eudes founded his first seminary in Caen, where the Eudist Fathers congregation was based.
However, Eudes’s most revered achievement was promoting the devotions to the Sacred Heart of Jesus and the Immaculate Heart of Mary. In 1648 he wrote the first mass and divine office (a public service of praise and worship performed at specific times of the day and night) in honor of the Immaculate Heart of Mary. In 1672 he composed the first mass and office in honor of the Sacred Heart of Jesus.
He was canonized as a saint in 1925 by Pope Pius XI, who called him “the father, doctor, and apostle of liturgical devotion to the hearts of Jesus and Mary.”
