The Missionary Society of St. Paul is a Roman Catholic missionary congregation of priests and brothers, founded in Malta in 1910 by Mgr. Joseph De Piro. According to its Constitutions, "the purpose of the Society is the evangelisation and the implanting of the Church in missionary lands known as mission Ad Gentes. Consequently its apostolic endeavours in those countries not strictly considered missionary must be orientated towards promoting and creating an awareness of missionary activity."
