(Company of the Most Blessed Sacrament) A Catholic secret society founded in France, 1630, by Henri de Levis, Duke de Ventadour; Henri de Pichery; Jacques Adhemar de Monteil de Grignan; and Philippe d' Angoumois. The object of the company was to increase conversions, to organize the preaching of missions for Protestants, and to suppress the outrages perpetrated by Protestants against Catholics. In 1660 the last general meeting was held and the society began to decline. The General Hospital and the Seminary of Foreign Missions owe their foundation to this association.
