Vincentian, member of a Roman Catholic society of priests and brothers founded at Paris in 1625 by St. Vincent de Paul for the purpose of preaching missions to the poor country people and training young men in seminaries for the priesthood. To its original work the congregation has added extensive foreign missions, educational work, and chaplaincies to hospitals, prisons, and the armed forces.
Following the congregation’s approval by Pope Urban VIII in 1632, Vincent took possession of the former priory of Saint-Lazare at Paris, whence the name Lazarists. From this headquarters 550 missions to the rural poor were organized before Vincent’s death in 1660. The Vincentians also became involved in the work of clerical training very early. They started giving retreats at Saint-Lazare in 1631 for men about to be ordained, and soon five or six retreats were given each year. The Vincentians opened a permanent house in Rome in 1642, and shortly thereafter the pope directed that all those to be ordained in Rome were obliged to make a retreat with the Vincentians. The French Revolution inflicted great suffering on the Vincentians, but growth began again in the early 19th century. The Vincentians arrived in the United States in 1816, making their first foundation in St. Louis, Missouri.
