Saint Jean-Baptiste-Marie Vianney, T.O.S.F. († 1859), commonly known in English as St. John Vianney, was a French parish priest who is venerated in the Catholic Church as a saint and as the patron saint of parish priests. He is often referred to as the "Curé d'Ars" (i.e., Parish Priest of Ars), internationally known for his priestly and pastoral work in his parish in Ars, France, because of the radical spiritual transformation of the community and its surroundings. Catholics attribute this to his saintly life, mortification, his persevering ministry in the sacrament of confession, and his ardent devotion to the Blessed Virgin Mary. On 3 October 1874 Pope Pius IX proclaimed him "venerable"; on 8 January 1905, Pope Pius X declared him Blessed. In 1925 John Mary Vianney was canonized by Pope Pius XI, who in 1929 made him the patron saint of parish priests. His feast day is 4 August.
