The Society of Jesus (Latin: Societas Iesu; abbreviated SJ), also known as the Jesuits (; Latin: Iesuitæ), is a religious order of the Catholic Church headquartered in Rome. It was founded by Ignatius of Loyola and six companions with the approval of Pope Paul III in 1540. The society is engaged in evangelization and apostolic ministry in 112 nations. Jesuits work in education, research, and cultural pursuits. Jesuits also give retreats, minister in hospitals and parishes, sponsor direct social ministries, and promote ecumenical dialogue.
