Saint John Eudes: Feast Day and His Sacred Heart Legacy
Saint John Eudes spent his entire priesthood pursuing causes that others had overlooked, from plague victims to women trying to escape prostitution. Along the way, he founded two lasting religious institutes and helped popularise one of Catholicism’s most beloved devotions. Long before Saint Margaret Mary Alacoque’s famous visions, Eudes had already begun writing liturgical texts honouring the Sacred Heart of Jesus. This piece traces his early ministry, his religious foundations and the devotion that became his defining legacy.
Saint John Eudes’s Feast Day Falls on 19 August
The Catholic Church honours Saint John Eudes every year on 19 August, marking his death in 1680. Pope Pius X beatified him in 1909, and Pope Pius XI canonised him in 1925. Supporters have since petitioned Rome to name him a Doctor of the Church, with several national bishops’ conferences formally backing the cause since 2014.
A Farmer’s Son Drawn Toward the Priesthood
Eudes was born on 14 November 1601 near the village of Ri in Normandy, the son of a surgeon named Isaac Eudes. At just fourteen, he privately vowed to remain chaste, foreshadowing the religious life ahead of him. He studied under the Jesuits at Caen before joining the Oratorians in 1623, training under influential spiritual figures including Pierre de Bérulle and Charles de Condren. He was ordained a priest in December 1625, celebrating his first Mass that same Christmas.
Risking His Life During Plague Outbreaks
When plague struck Normandy in 1627 and again in 1631, Eudes volunteered to care for the dying, administering sacraments and ensuring proper burials for victims others feared to approach. To avoid infecting his fellow priests, he reportedly lived inside a large cask set in an open field during this period. This willingness to serve in genuinely dangerous conditions shaped his reputation long before his later fame as a preacher.
Saint John Eudes Becomes a Celebrated Missionary
From 1633 onward, Eudes preached parish missions across France, eventually delivering more than one hundred throughout his lifetime. His missions frequently lasted weeks or even months, drawing praise from contemporaries such as Jean-Jacques Olier, who called him the prodigy of his age. He preached three separate missions in Paris and one at Versailles, even addressing Anne of Austria directly, though her son King Louis XIV reportedly suspected him of opposing royal religious policy.
Founding Refuge for Women in Need
Challenged directly by a laywoman named Madeleine Lamy, Eudes grew increasingly troubled by the lack of adequate shelter for women seeking to leave prostitution. In 1641, he founded a refuge in Caen to support this work, which received official diocesan approval a decade later. The community eventually became known as the Sisters of Our Lady of Charity of the Refuge, receiving full papal approval from Pope Alexander VII in 1666. This same foundation later inspired Saint Mary Euphrasia Pelletier’s own Congregation of the Good Shepherd in 1829.
Establishing the Eudists
In 1643, with backing from Cardinal Richelieu, Eudes left the Oratorians to found the Congregation of Jesus and Mary, now known as the Eudists, dedicated to training priests and preaching missions. Papal approval for this new congregation proved difficult to secure, facing resistance from both the Oratorians and Jansenist opponents. Despite this setback, the Bishop of Coutances invited him to establish a seminary there in 1650 and further seminaries soon followed at Lisieux, Rouen, Évreux and Rennes.
Pioneering Devotion to the Sacred Hearts
Saint John Eudes composed the first-ever liturgical Mass and Office dedicated to the Sacred Heart of Jesus, alongside similar texts honouring the Immaculate Heart of Mary. His 1670 book on Mary’s heart became the very first work ever written specifically on that devotion. Pope Leo XIII later honoured him in 1903 with the title Author of the Liturgical Worship of the Sacred Heart of Jesus and Immaculate Heart of Mary, recognising work that predated Saint Margaret Mary Alacoque’s own celebrated visions.
Death and Lasting Influence
Saint John Eudes died at Caen on 19 August 1680, having finished his final major work on Mary’s heart just a month earlier. Pope Benedict XVI later praised him during a 2009 General Audience as a tireless apostle of devotion to the Sacred Hearts, holding him up as a model for priests during the Year for Priests.
