John Vianney, French priest and saint (d. 1859)
John Vianney (born Jean-Baptiste-Marie Vianney; 8 May 1786 – 4 August 1859), venerated as Saint John Vianney, was a French Catholic 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. the 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, persevering ministry in the sacrament of confession, and ardent devotion to the Blessed Virgin Mary. His feast day is August 4 in the Novus Ordo calendar, is August 8 in the Missal of 1962 calendar, and is August 9 in the pre-1955 calendar.
