Saint John Eudes was born in Normandy, France to a farming family. He was ordained a priest in 1625 and was an eloquent preacher and confessor. Seeing a need to improve seminarian formation, he founded the Congregation of Jesus and Mary (the Eudist). Also realizing that Christian care for prostitutes was lacking, he founded the Sisters of Charity of the Refuge. Both he and St. Mary Margaret Alacoque spread devotion to the Sacred Hearts of Jesus and Mary. He authored the Mass of the Sacred Hearts of Jesus and Mary before he died.
