The Society of Jesus (Latin: Societas Iesu; abbreviation: S.J. or SJ), also known as the Jesuit Order or the Jesuits ( JEZH-oo-its, JEZ-ew-; Latin: Iesuitae), is a religious order of clerics regular of pontifical right for men in the Catholic Church. Headquartered in Rome, it was founded in 1540 by Ignatius of Loyola and six companions, with the approval of Pope Paul III. The Society of Jesus is the largest Catholic religious male order and it has played a significant role in education, charity, humanitarian acts and global policies. Jesuits are engaged in evangelization and apostolic ministry in 112 countries, including education, research, and cultural pursuits. They also conduct retreats, minister in hospitals and parishes, sponsor direct social and humanitarian works, 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, also in Rome.
Jesuits make profession of "perpetual poverty, chastity, and obedience" and "promise a special obedience to the sovereign pontiff in regard to the missions." A Jesuit is expected to be totally available and obedient to his superiors, accepting orders to go anywhere in the world, even if required to live in extreme conditions. Ignatius, its leading founder, was a nobleman who had a military background. The opening lines of the founding document of the Society of Jesus accordingly declare that it was founded for "whoever desires to serve as a soldier of God, to strive especially for the defense 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 of Jesus participated in the Counter-Reformation and, later, in the implementation of the Second Vatican Council.

Jesuit missionaries established missions around the world from the 16th to the 18th century and had both successes and failures in Christianizing the native peoples. The Jesuits have always been controversial within the Catholic Church and have frequently clashed with secular governments and institutions. Beginning in 1759, the Catholic Church expelled Jesuits from most countries in Europe and from European colonies. Pope Clement XIV officially suppressed the order in 1773. In 1814, the Church lifted the suppression.
History
Foundation
Ignatius of Loyola, a Basque nobleman from the Pyrenees area of northern Spain, founded the society after discerning his spiritual vocation while recovering from a wound sustained in the Battle of Pamplona.
On 15 August 1534, Ignatius of Loyola (born Íñigo López de Loyola), a Spaniard from the Basque city of Loyola, and six others mostly of Castilian origin, all students at the University of Paris, met in Montmartre outside Paris, in a crypt beneath the church of Saint Denis, now Saint Pierre de Montmartre, to pronounce promises of poverty, chastity, and obedience. Ignatius' six companions were: Francisco Xavier from Navarre (modern Spain), Alfonso Salmeron, Diego Laínez, Nicolás Bobadilla from Castile (modern Spain), Peter Faber from Savoy, and Simão Rodrigues from Portugal.

The meeting is commemorated in the Martyrium of Saint Denis, Montmartre. They called themselves the Compañía de Jesús, and also Amigos en El Señor or "Friends in the Lord", because they felt "they were placed together by Christ." The name "company" had echoes of the military (reflecting perhaps Ignatius' background as captain in the Spanish army) as well as of discipleship (the "companions" of Jesus). The Spanish "company" would be translated into Latin as societas like in socius, a partner or comrade. From this came Societas Iesu (S.J.), in English Society of Jesus, by which they would be known more widely.
Religious orders established in the medieval era were named after particular men: Francis of Assisi (Franciscans); Domingo de Guzmán, later canonized as Saint Dominic (Dominicans); and Augustine of Hippo (Augustinians). Ignatius of Loyola and his followers appropriated the name of Jesus for their new order, provoking resentment by other orders who considered it presumptuous. The resentment was recorded by Jesuit José de Acosta of a conversation with the Archbishop of Santo Domingo.
In the words of one historian: "The use of the name Jesus gave great offense. Both on the Continent and in England, it was denounced as blasphemous; petitions were sent to kings and to civil and ecclesiastical tribunals to have it changed; and even Pope Sixtus V had signed a Brief to do away with it." But nothing came of all the opposition; there were already congregations named after the Trinity and as "God's daughters".

In 1537, the seven travelled to Italy to seek papal approval for their order. Pope Paul III gave them a commendation, and permitted them to be ordained priests. These initial steps led to the official founding in 1540.
They were ordained in Venice by the bishop of Arbe on 24 June. They devoted themselves to preaching and charitable work in Italy. The Italian War of 1536–1538 renewed between Charles V, Holy Roman Emperor, Venice, the Pope, and the Ottoman Empire, had rendered any journey to Jerusalem impossible.
Again in 1540, they presented the project to Paul III. After months of dispute, a congregation of cardinals reported favourably upon the Constitution presented, and Paul III confirmed the order through the bull Regimini militantis ecclesiae ("To the Government of the Church Militant"), on 27 September 1540. This is the founding document of the Society of Jesus as an official Catholic religious order. Ignatius was chosen as the first Superior General. Paul III's bull had limited the number of its members to sixty. This limitation was removed through the bull Exposcit debitum of Julius III in 1550.

In 1543, Peter Canisius entered the company. Ignatius sent him to Messina, where he founded the first Jesuit college in Sicily.
Ignatius laid out his original vision for the new order in the "Formula of the Institute of the Society of Jesus", which is "the fundamental charter of the order, of which all subsequent official documents were elaborations and to which they had to conform". He ensured that his formula was contained in two papal bulls signed by Pope Paul III in 1540 and by Pope Julius III in 1550. The formula expressed the nature, spirituality, community life, and apostolate of the new religious order. Its famous opening statement echoed Ignatius' military background:
Whoever desires to serve as a soldier of God beneath the banner of the Cross in our Society, which we desire to be designated by the Name of Jesus, and to serve the Lord alone and the Church, his spouse, under the Roman Pontiff, the Vicar of Christ on earth, should, after a solemn vow of perpetual chastity, poverty and obedience, keep what follows in mind. He is a member of a Society founded chiefly for this purpose: to strive especially for the defence and propagation of the faith and for the progress of souls in Christian life and doctrine, by means of public preaching, lectures and any other ministration whatsoever of the Word of God, and further by means of retreats, the education of children and unlettered persons in Christianity, and the spiritual consolation of Christ's faithful through hearing confessions and administering the other sacraments. Moreover, he should show himself ready to reconcile the estranged, compassionately assist and serve those who are in prisons or hospitals, and indeed, to perform any other works of charity, according to what will seem expedient for the glory of God and the common good.

In fulfilling the mission of the "Formula of the Institute of the Society", the first Jesuits concentrated on a few key activities. First, they founded schools throughout Europe. Jesuit teachers were trained in both classical studies and theology, and their schools reflected this. These schools taught with a balance of Aristotelian methods with mathematics.
Second, they sent out missionaries across the globe to evangelize those peoples who had not yet heard the Gospel, founding missions in widely diverse regions such as modern-day Paraguay, Japan, Ontario, and Ethiopia. One of the original seven arrived in India already in 1541. Finally, though not initially formed for the purpose, they aimed to stop Protestantism from spreading and to preserve communion with Rome and the pope. The zeal of the Jesuits overcame the movement toward Protestantism in the Polish–Lithuanian Commonwealth and southern Germany.
Ignatius wrote the Jesuit Constitutions, adopted in 1553, which created a centralised organization and stressed acceptance of any mission to which the pope might call them. His main principle became the unofficial Jesuit motto: Ad Maiorem Dei Gloriam ("For the greater glory of God"). This phrase is designed to reflect the idea that any work that is not evil can be meritorious for the spiritual life if it is performed with this intention, even things normally considered of little importance.

The Society of Jesus is classified among institutes as an order of clerks regular, that is, a body of priests organized for apostolic work, and following a religious rule.
The term Jesuit (of 15th-century origin, meaning "one who used too frequently or appropriated the name of Jesus") was first applied to the society in reproach (1544–1552). The term was never used by Ignatius of Loyola, but over time, members and friends of the society adopted the name with a positive meaning.
While the order is limited to men, Joanna of Austria, Princess of Portugal, favored the order and she is reputed to have been admitted surreptitiously under a male pseudonym.
Early works
The Jesuits were founded just before the Council of Trent (1545–1563) and ensuing Counter-Reformation that would introduce reforms within the Catholic Church, and so counter the Protestant Reformation throughout Catholic Europe.
Ignatius and the early Jesuits did recognize, though, that the hierarchical church was in dire need of reform. Some of their greatest struggles were against corruption, venality, and spiritual lassitude within the Catholic Church. Ignatius insisted on a high level of academic preparation for the clergy in contrast to the relatively poor education of much of the clergy of his time. The Jesuit vow against "ambitioning prelacies" can be seen as an effort to counteract another problem evidenced in the preceding century.
Ignatius and the Jesuits who followed him believed that the reform of the church had to begin with the conversion of an individual's heart. One of the main tools the Jesuits have used to bring about this conversion is the Ignatian retreat, called the Spiritual Exercises. During a four-week period of silence, individuals undergo a series of directed meditations on the purpose of life and contemplations on the life of Christ. They meet regularly with a spiritual director who guides their choice of exercises and helps them to develop a more discerning love for Christ.
The retreat follows a "Purgative-Illuminative-Unitive" pattern in the tradition of the spirituality of John Cassian and the Desert Fathers. Ignatius' innovation was to make this style of contemplative mysticism available to all people in active life. He used it as a means of rebuilding the spiritual life of the church. The Exercises became both the basis for the training of Jesuits and one of the essential ministries of the order: giving the exercises to others in what became known as "retreats".
The Jesuits' contributions to the late Renaissance were significant in their roles both as a missionary order and as the first religious order to operate colleges and universities as a principal and distinct ministry. By the time of Ignatius' death in 1556, the Jesuits were already operating a network of 74 colleges on three continents. A precursor to liberal education, the Jesuit plan of studies incorporated the Classical teachings of Renaissance humanism into the Scholastic structure of Catholic thought. This method of teaching was important in the context of the Scientific Revolution, as these universities were open to teaching new scientific and mathematical methodology. Further, many important thinkers of the Scientific Revolution were educated by Jesuit universities.
In addition to the teachings of faith, the Jesuit Ratio Studiorum (1599) would standardize the study of Latin, Greek, classical literature, poetry, and philosophy as well as non-European languages, sciences, and the arts. Jesuit schools encouraged the study of vernacular literature and rhetoric, and thereby became important centres for the training of lawyers and public officials.
The Jesuit schools played an important part in winning back to Catholicism a number of European countries which had for a time been predominantly Protestant, notably the Polish–Lithuanian Commonwealth. Jesuit colleges in the Polish–Lithuanian Commonwealth were established since the 1560s. Several Jesuit colleges enjoyed a good reputation and were also attended by future writers and high-ranking state officials. Today, Jesuit colleges and universities are located in over one hundred nations around the world. Under the notion that God can be encountered through created things and especially art, they encouraged the use of ceremony and decoration in Catholic ritual and devotion. Perhaps as a result of this appreciation for art, coupled with their spiritual practice of "finding God in all things", many early Jesuits distinguished themselves in the visual and performing arts as well as in music. The theater was a form of expression especially prominent in Jesuit schools.
Jesuit priests often acted as confessors to kings during the early modern period. They were an important force in the Counter-Reformation and in the Catholic missions, in part because their relatively loose structure (without the requirements of living and celebration of the Liturgy of Hours in common) allowed them to be flexible and meet diverse needs arising at the time.
Expansion of the order
After much training and experience in theology, Jesuits went across the globe in search of converts to Christianity. Despite their dedication, they had little success in Asia, except in the Philippines. For instance, early missions in Japan resulted in the government granting the Jesuits the feudal fiefdom of Nagasaki in 1580. This was removed in 1587 due to fears over their growing influence. Jesuits did, however, have much success in Latin America. Their ascendancy in societies in the Americas accelerated during the seventeenth century, wherein Jesuits created new missions in Peru, Colombia, and Bolivia. As early as 1603, there were 345 Jesuit priests in Mexico alone.
In 1541, Francis Xavier, one of the original companions of Loyola, arrived in Goa, Portuguese India, to carry out evangelical service in the Indies. In a 1545 letter to John III of Portugal, he requested an Inquisition to be installed in Goa to combat heresies like crypto-Judaism and crypto-Islam. Under Portuguese royal patronage, Jesuits thrived in Goa and until 1759 successfully expanded their activities to education and healthcare.
In 1594, they founded the first Roman-style academic institution in the East, St. Paul Jesuit College in Macau, China. Founded by Alessandro Valignano, it had a great influence on the learning of Eastern languages (Chinese and Japanese) and culture by missionary Jesuits, becoming home to the first western sinologists such as Matteo Ricci. Jesuit efforts in Goa were interrupted by the expulsion of the Jesuits from Portuguese territories in 1759 by the powerful Marquis of Pombal, the Secretary of State in Portugal.
In 1624, the Portuguese Jesuit António de Andrade founded a mission in Western Tibet. In 1661, two Jesuit missionaries, Johann Grueber and Albert Dorville, reached Lhasa, in Tibet. The Italian Jesuit Ippolito Desideri established a new Jesuit mission in Lhasa and Central Tibet (1716–21) and gained an exceptional mastery of Tibetan language and culture, writing a long and very detailed account of the country and its religion as well as treatises in Tibetan that attempted to refute key Buddhist ideas and establish the truth of Catholic Christianity.
Jesuit missions in the Americas became controversial in Europe, especially in Spain and Portugal, where they were seen as interfering with the proper colonial enterprises of the royal governments. The Jesuits were often the only force standing between the Indigenous and slavery. Together throughout South America but especially in present-day Brazil and Paraguay, they formed Indigenous Christian city-states, called "reductions". These were societies set up according to an idealized theocratic model.
The efforts of Jesuits like Antonio Ruiz de Montoya to protect the natives from enslavement by Spanish and Portuguese colonizers contributed to the call for the society's suppression. Jesuit priests such as Manuel da Nóbrega and José de Anchieta founded several towns in Brazil in the 16th century, including São Paulo and Rio de Janeiro, and were very influential in the pacification, religious conversion, and education of indigenous nations. They built schools, organized people into villages, and created a writing system for the local languages of Brazil. José de Anchieta and Manuel da Nóbrega were the first Jesuits that Ignacio de Loyola sent to the Americas.
Jesuit scholars working in foreign missions were very dedicated in studying the local languages and strove to produce Latinized grammars and dictionaries. This included: Japanese (see Nippo jisho, also known as Vocabvlario da Lingoa de Iapam, "Vocabulary of the Japanese Language", a Japanese–Portuguese dictionary written 1603); Vietnamese (Portuguese missionaries created the Vietnamese alphabet, which was later formalized by Avignon missionary Alexandre de Rhodes with his 1651 trilingual dictionary); Tupi, the main language of Brazil, and the pioneering study of Sanskrit in the West by Jean François Pons in the 1740s.
Jesuit missionaries were active among indigenous peoples in New France in North America, many of them compiling dictionaries or glossaries of the First Nations and Native American languages they had learned. For instance, before his death in 1708, Jacques Gravier, vicar general of the Illinois Mission in the Mississippi River valley, compiled a Miami–Illinois–French dictionary, considered the most extensive among works of the missionaries. Extensive documentation was left in the form of The Jesuit Relations, published annually from 1632 until 1673.
Britain
Whereas Jesuits were active in Britain in the 1500s, due to the persecution of Catholics in the Elizabethan times, an English province was only established in 1623. The first pressing issue for early Jesuits in what today is the United Kingdom, was to establish places for training priests. In 1579, an English College was opened in Rome. In 1589, a Jesuit seminary was opened at Valladolid.
In 1592, an English College was opened in Seville. In 1614, an English college opened in Louvain. This was the earliest foundation of what was later Heythrop College. Campion Hall, founded in 1896, has been a presence within Oxford University since then.
16th and 17th-century Jesuit institutions intended to train priests were hotbeds for the persecution of Catholics in Britain, where men suspected of being Catholic priests were routinely imprisoned, tortured, and executed. Jesuits were among those killed, including the namesake of Campion Hall, as well as Brian Cansfield, Ralph Corbington, and many others. A number of them were canonized among the Forty Martyrs of England and Wales.
In 2022, four Jesuit churches existed in London, with three other places of worship in England and two in Scotland.
China
The Jesuits first entered China through the Portuguese settlement on Macau, where they settled on Green Island and founded St. Paul's College.
The Jesuit China missions of the 16th and 17th centuries introduced Western science and astronomy, then undergoing its own revolution, to China. The scientific revolution brought by the Jesuits coincided with a time when scientific innovation had declined in China:
[The Jesuits] made efforts to translate western mathematical and astronomical works into Chinese and aroused the interest of Chinese scholars in these sciences. They made very extensive astronomical observation and carried out the first modern cartographic work in China. They also learned to appreciate the scientific achievements of this ancient culture and made them known in Europe. Through their correspondence, European scientists first learned about the Chinese science and culture.
For over a century, Jesuits such as Michele Ruggieri, Matteo Ricci, Diego de Pantoja, Philippe Couplet, Michal Boym, and François Noël refined translations and disseminated Chinese knowledge, culture, history, and philosophy to Europe. Their Latin works popularized the name "Confucius" and had considerable influence on the Deists and other Enlightenment thinkers, some of whom were intrigued by the Jesuits' attempts to reconcile Confucian morality with Catholicism.
Upon the arrival of the Franciscans and other monastic orders, Jesuit accommodation of Chinese culture and rituals led to the long-running Chinese Rites controversy. Despite the personal testimony of the Kangxi Emperor and many Jesuit converts that Chinese veneration of ancestors and Confucius was a nonreligious token of respect, Pope Clement XI's papal decree Cum Deus Optimus ruled that such behavior constituted impermissible forms of idolatry and superstition in 1704.
His legate Tournon and Bishop Charles Maigrot of Fujian, tasked with presenting this finding to the Kangxi Emperor, displayed such extreme ignorance that the emperor mandated the expulsion of Christian missionaries unable to abide by the terms of Ricci's Chinese catechism. Tournon's summary and automatic excommunication for any violators of Clement's decree – upheld by the 1715 bull Ex Illa Die – led to the swift collapse of all the missions in China. The last Jesuits were expelled after 1721.
Ireland
The first Jesuit school in Ireland was established at Limerick by the apostolic visitor of the Holy See, David Wolfe. Wolfe was sent to Ireland by Pope Pius IV with the concurrence of the third Jesuit superior general, Diego Laynez. He was charged with setting up grammar schools "as a remedy against the profound ignorance of the people".
Wolfe's mission in Ireland initially concentrated on setting the sclerotic Irish Church on a sound footing, introducing the Tridentine Reforms and finding suitable men to fill vacant sees. He established a house of religious women in Limerick known as the Menabochta ("poor women") and in 1565 preparations began for establishing a school at Limerick.
At his instigation, Richard Creagh, a priest of the Diocese of Limerick, was persuaded to accept the vacant Archdiocese of Armagh, and was consecrated in Rome in 1564.
This early Limerick school, Crescent College, operated in difficult circumstances. In April 1566, William Good sent a detailed report to Rome of his activities via the Portuguese Jesuits. He informed the Jesuit superior general that he and Edmund Daniel had arrived at Limerick two years beforehand and their situation there had been perilous. Both had arrived in the city in very bad health, but had recovered due to the kindness of the people.
They established contact with Wolfe, but were only able to meet with him at night, as the Dublin Castle administration was attempting to arrest the legate. Wolfe charged them initially with teaching to the boys of Limerick, with an emphasis on religious instruction, and Good translated the catechism from Latin into English for this purpose. They remained in Limerick for eight months.
In December 1565, they moved to Kilmallock under the protection of the Earl of Desmond, where they lived in more comfort than the primitive conditions they experienced in Limerick. They were unable to support themselves at Kilmallock and three months later they returned to Limerick in Easter 1566, and strangely set up their house in accommodation owned by the Lord Deputy of Ireland, which was conveyed to them by certain influential friends.
