a Roman Catholic religious congregation founded in 1816 in the diocese of Belley, Fr., by Jean-Claude Courveille and Jean-Claude-Marie Colin to undertake all ministerial works—parishes, schools, hospital chaplaincies, and the foreign missions (mission)—while stressing the virtues of the Virgin Mary. Its foreign missions, the acceptance of which was the chief reason for its approval by Rome in 1836, embrace the islands of the South Pacific (the congregation's original mission field), Japan, Algeria, Peru, and Venezuela. Stemming from the Marist Fathers are the Marist Brothers, the Marist Sisters, the Missionary Sisters of the Society of Mary, and the Marist Third Order.
