The Society of Jesus (Jesuits) receives its charter from Pope Paul III.
Pope Paul III (Latin: Paulus III; Italian: Paolo III; 29 February 1468 10 November 1549), born Alessandro Farnese, was head of the Catholic Church and ruler of the Papal States from 13 October 1534 to his death in 1549.
He came to the papal throne in an era following the sack of Rome in 1527 and rife with uncertainties in the Catholic Church following the Protestant Reformation. His pontificate initiated the Counter-Reformation with the Council of Trent in 1545, as well as the wars of religion with Emperor Charles V's military campaigns against the Protestants in Germany. He recognized new Catholic religious orders and societies such as the Jesuits, the Barnabites, and the Congregation of the Oratory. His efforts were distracted by nepotism to advance the power and fortunes of his family, including his illegitimate son Pier Luigi Farnese.
Paul III was a significant patron of artists including Michelangelo, and it is to him that Nicolaus Copernicus dedicated his heliocentric treatise.
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.
The Society of Jesus is consecrated under the patronage of Madonna Della Strada, a title of the Blessed Virgin Mary, and it is led by a Superior General. The headquarters of the society, its General Curia, is in Rome. The historic curia of Ignatius is now part of the Collegio del Gesù attached to the Church of the Gesù, the Jesuit mother church.
Members of the Society of Jesus are expected to accept orders to go anywhere in the world, where they might be required to live in extreme conditions. This was so because Ignatius, its leading founder, was a nobleman who had a military background. Accordingly, the opening lines of the founding document declared that the society was founded for "whoever desires to serve as a soldier of God, to strive especially for the defence and propagation of the faith, and for the progress of souls in Christian life and doctrine". Jesuits are thus sometimes referred to colloquially as "God's soldiers", "God's marines", or "the Company". The society participated in the Counter-Reformation and, later, in the implementation of the Second Vatican Council.
