A Religious Sister at the Presentation Convent Girls High School in Pakistan

A nun is a member of a religious community of women, typically one living under vows of poverty, chastity, and obedience. She may be a woman who decided to dedicate her life to serving all other living beings or to be an ascetic who voluntarily chooses to leave mainstream society and live her life in prayer and contemplation in a monastery or convent. The term "nun" is applicable to Catholics (eastern and western traditions) Orthodox Christians, Anglicans, Lutherans, Jains, Buddhists, Taoists, and Hindus.

While in common usage the terms "nun" and "Sister" are often used interchangeably (the same title of "Sister" for the individual member of both forms), they are considered different ways of life, with a "nun" being a religious woman who lives a contemplative and cloistered life of meditation and prayer for the salvation of others, while a "Religious Sister", in religious institutes like Mother Teresa's Missionaries of Charity, lives an active vocation of both prayer and service, often to the needy, sick, poor, and uneducated.

All Buddhist traditions have nuns, although their status is different among Buddhist countries. The Buddha is reported to have allowed women into the sangha only with great reluctance, predicting that the move would lead to Buddhism's collapse after 500 years, rather than the 1,000 years it would have enjoyed otherwise. (This prophecy occurs only once in the Canon and is the only prophecy involving time in the Canon, leading some to suspect that it is a late addition.) Fully ordained Buddhist nuns ( bhikkhunis) have more Patimokkha rules than the monks ( bhikkhus). The important vows are the same, however.

As with monks, there is quite a lot of variation in nuns' dress and social conventions between Buddhist cultures in Asia. Chinese nuns possess the full bhikkuni ordination, Tibetan nuns do not, and in Theravada countries female renunciates are discouraged from even wearing saffron robes. Disparities may often be observed in the amount of respect and financial resources given to monks vs. nuns, with nuns receiving less of both in all countries with the possible exception of Taiwan. Despite barriers, some nuns succeed in becoming religious teachers and authorities.

In Thailand, a country which never had a tradition of fully ordained nuns (bhikkhuni), there developed a separate order of non-ordained female renunciates called mae ji. However, some of them have played an important role in dharma-practitioners' community. There are in Thai Forest Tradition foremost nuns such as Mae Ji Kaew Sianglam, the founder of the Nunnery of Baan Huai Saai, who is believed to be enlightened as well as Upāsikā Kee Nanayon. At the beginning of the 21st century, some Buddhist women in Thailand have started to introduce the bhikkhuni sangha in their country as well, even if public acceptance is still lacking. Dhammananda Bhikkhuni, formerly the successful academic scholar Dr. Chatsumarn Kabilsingh, established a controversial monastery for the training of Buddhist nuns in Thailand.


Chinese Buddhism possesses a full bhikkuni tradition. Thanks largely to the efforts of Master Cheng Yen of the Buddhist charity Tzu Chi (which utterly dominates philanthropic giving in Taiwan), Taiwan's nuns nowadays probably receive more public respect and support than monks.

Researcher Charles Brewer Jones estimates that since 1952, when the Buddhist Association of the ROC organized public ordination, female applicants have outnumbered males by about three to one. He adds:

"All my informants in the areas of Taipei and Sanhsia considered nuns at least as respectable as monks, or even more so. [...] In contrast, however, Shiu-kuen Tsung found in Taipei county that female clergy were viewed with some suspicion by society. She reports that while outsiders did not necessarily regard their vocation as unworthy of respect, they still tended to view the nuns as social misfits."


The August 2007 International Congress on Buddhist Women's Role in the Sangha, with the support of H. H. XIVth Dalai Lama, reinstated the Gelongma ( Dharmaguptaka vinaya bhikkhuni) lineage, having been lost, in India and Tibet, for centuries. Gelongma ordination requires the presence of ten fully ordained people keeping exactly the same vows. Because ten nuns are required to ordain a new one, the effort to establish the Dharmaguptaka bhikkhu tradition has taken a long time.

It is permissible for a Tibetan nun to receive bhikkhuni ordination from another living tradition, e.g., in Vietnam. Based on this, Western nuns ordained in Tibetan tradition, like Thubten Chodron, took full ordination in another tradition.

The ordination of monks and nuns in Tibetan Buddhism distinguishes three stages: rabjung-ma, getshül-ma and gelong-ma. The clothes of the nuns in Tibet are basically the same as those of monks, but there are differences between novice and gelong robes.


Hokke-ji in 747 was established by the consort of the Emperor. It took charge of provincial convents, performed ceremonies for the protection of the state, and became the site of pilgrimages. Aristocratic Japanese women often became Buddhist nuns in the premodern period. Originally it was thought they could not gain salvation because of the Five Hindrances, which said women could not attain Buddhahood until they changed into men. However, in 1249, 12 women received full ordination as priests.


Roman Catholic

In the Catholic Church, nuns have played a major role for 2000 years. A Catholic nun is a woman who has taken solemn vows (the male equivalent is often called a monk or friar). A major traditional distinction between a nun and a Religious Sister is that nuns are members of enclosed religious orders and take "solemn" religious vows, through which they renounce all property, including inheritances, while Sisters have "simple" vows, which allows them to inherit property. Also, as monastics, nuns commit themselves to the daily recitation of the Liturgy of the Hours throughout the day in church, usually in a solemn manner. As a result of this way of life, for those making this commitment, they are distinguished within the monastic community under the title of 'choir nuns', as opposed to lay Sisters, who are entrusted with the upkeep of the monastery, or even running errands outside the cloister. This last task, though, is often entrusted to women, called 'externs', who live outside the enclosure proper. They do not belong to the Order of the nuns and were usually either oblates or members of the associated Third Order, often wearing the standard woman's attire of the period.

In the Roman Catholic tradition, there are a large number of religious institutes of nuns and Sisters, each with its own charism or special character.

In general, when a woman enters a convent, monastery or abbey, she first undergoes a period of testing the life for six months to a year called a postulancy. If she, and the Order, determine that she may have a vocation to the life, she receives the habit of the Order (usually with some modification, normally a white veil instead of a black, to distinguish her from professed members) and undertakes the novitiate, a period (that lasts one to two years) of living the life of the religious institute without yet taking vows. Upon completion of this period she may take her initial, temporary vows. Temporary vows last one to three years, typically, and will be professed for not less than three years and not more than six. Finally, she will petition to make her "perpetual profession", taking permanent, solemn vows.

In the branches of the Benedictine tradition, (Benedictines, Cistercians, Camaldolese, and Trappists, among others) nuns take vows of 'stability' (that is, to remain a member of a single monastic community), 'obedience' (to an abbess or prioress), and "conversion of life" (which includes poverty and celibacy). In other traditions, such as the " Poor Clares" (the Franciscan Order) and the Dominican nuns, they take the threefold vows of poverty, chastity and obedience. Most Orders of nuns not listed here follow one of these two patterns, with some Orders taking an additional vow related to the specific work or character of their Order (for example, to undertake a certain style of devotion, praying for a specific intention or purpose).

Cloistered nuns ( Carmelites, for example) observe "papal enclosure" rules, and their monasteries typically have walls separating the nuns from the outside world. The nuns rarely leave (except for medical necessity or occasionally for purposes related to their contemplative life) though they may have visitors in specially built parlors, often with either a "grill" or half-wall separating the nuns' side from the visitors', that allow them to meet with outsiders. They are usually self-sufficient, earning money by selling jams. candies. or baked goods by mail order, or by making liturgical items (such as vestments, candles, or hosts to be Consecrated at Mass for Holy Communion).

They often undertake contemplative ministries — that is, a monastery of nuns is often associated with prayer for some particular good or supporting the missions of another Order by prayer (for instance, the Dominican nuns of Corpus Christi Monastery in the Bronx, New York, pray in support of the priests of the Archdiocese of New York). Yet Religious Sisters can also do this form of ministry, e.g., the Maryknoll Missionary Sisters have small houses of contemplative Sisters, some in mission locations, who pray for the work of the priests, brothers and other Sisters of their Congregation; the Sister Disciples of the Divine Master are also cloistered Sisters who pray in support of their sister congregation, the Daughters of St. Paul in their media ministry.

A canoness is a nun who corresponds to the male equivalent, a canon. The origin and rules of monastic life are common to both. As with the canons, differences in the observance of rule gave rise to two types: the canoness regular, taking the traditional religious vows, and the secular canoness, who did not take vows and thus remained free to own property and leave to marry, should they choose. This was primarily a way of leading a pious life for the women of aristocratic families and generally disappeared in the modern age, except for the modern Lutheran convents of Germany.

A nun who is elected to head her religious house is termed an abbess if the house is an abbey, a prioress if it is a monastery, or more generically may be referred to as "Mother Superior" and styled "Reverend Mother". The distinction between abbey and monastery has to do with the terms used by a particular Order or by the level of independence of the religious house. Technically, a convent is any home of a community of sisters — or, indeed, of priests and brothers, though this term is rarely used in the United States. The term "monastery" is often used by communities within the Benedictine family, and "convent" (when referring to a cloister) is often used of the houses of certain other institutes.

The traditional dress for women in religious communities consists of a tunic, which is tied around the waist with a cloth or leather belt. Over the tunic some nuns wear a scapular which is a garment of long wide piece of woolen cloth worn over the shoulders with an opening for the head. Some wear a white wimple, which "encircles" the face and a veil, the most significant and ancient aspect of the habit. Some Orders—such as the Dominicans—wear a large rosary on their belt. Benedictine abbesses wear a cross or crucifix on a chain around their neck.

After the second Vatican Council, many religious institutes chose in their own regulations to no longer wear the traditional habit and did away with choosing a religious name. Catholic Church canon law states: "Religious are to wear the habit of the institute, made according to the norm of proper law, as a sign of their consecration and as a witness of poverty."

Distinction between a nun and a religious sister

21st Century religious sister — Sister Rosália Sehnem, of the Sisters of St. Francis of Penance and Christian Charity

During the first millennium, nearly all communities of men and women were dedicated to prayer and contemplation. These monasteries, abbeys, or convents were built in remote locations or were separated from the world by means of a cloister. The mendicant orders, founded in the 13th century, combined a life of prayer and dedication to God with active works of preaching, hearing confessions, and service to the poor, and members of these orders are known as friars rather than monks. At that time, Church law did not allow women to leave the cloister if they had taken religious vows. Female members of the mendicant orders ( Dominican, Augustinian and Carmelite nuns and Poor Clares) continued to observe the same enclosed life as members of the monastic orders.

Originally, the vows taken by profession in any religious institute approved by the Holy See were classified as solemn. This was declared by Pope Boniface VIII (1235–1303). The situation changed in the 16th century. In 1521, two years after the Fourth Lateran Council had forbidden the establishment of new religious institutes, Pope Leo X established a religious Rule with simple vows for those tertiaries attached to existing communities who undertook to live a formal religious life. In 1566 and 1568, Pope Pius V rejected this class of congregation, but they continued to exist and even increased in number. After at first being merely tolerated, they afterwards obtained approval. In the 20th century, Pope Leo XIII recognized as religious all men and women who took simple vows. Their lives were oriented not to the ancient monastic way of life, but more to social service and to evangelization, both in Europe and in mission areas. Their number had increased dramatically in the upheavals brought by the French Revolution and subsequent Napoleonic invasions of other Catholic countries, depriving thousands of religious of the income that their communities held because of inheritances and forcing them to find a new way of living the religious life. But members of these new associations were not recognized as "religious" until Pope Leo XIII's Constitution "Conditae a Christo" of 8 December 1900.

The 1917 Code of Canon Law reserved the term "nun" (Latin: monialis) for women religious who took solemn vows or who, while being allowed in some places to take simple vows, belonged to institutes whose vows were normally solemn. It used the word "sister" (Latin: soror) exclusively for members of institutes for women that it classified as " congregations"; and for "nuns" and "sisters" jointly it used the Latin word religiosae (women religious). The same religious Order could include both "nuns" and "sisters", if some members took solemn vows and others simple vows.

The new legal code of the Catholic Church which was adopted in 1983, however, remained silent on this matter. Whereas previously, the Code distinguised between Orders and congregations, the Code refers simply to religious institutes.


Eastern Orthodox

In the Eastern Orthodox Church there is no distinction between a monastery for women and one for men. In Greek, Russian, and other Eastern European languages, both domiciles are called "monasteries" and the ascetics who live therein are "Monastics". In English, however, it is acceptable to use the terms "nun" and "convent" for clarity and convenience. The term for an abbess is the feminine form of abbot ( hegumen)—Greek: hegumeni; Serbian: Игуманија (Igumanija); Russian: игумения, ( igumenia). Orthodox monastics do not have distinct "orders" as in Western Christianity. Orthodox monks and nuns lead identical spiritual lives. There may be slight differences in the way a monastery functions internally but these are simply differences in style (Gr. typica) dependent on the Abbess or Abbot. The Abbess is the spiritual leader of the convent and her authority is absolute (no priest, bishop, or even patriarch can override an abbess within the walls of her monastery.) There has always been spiritual equality between men and women in the Orthodox Church ( Galatians 3:28). Abbots and Abbesses rank in authority equal to bishops in many ways and were included in ecumenical councils. Orthodox monasteries are usually associated with a local synod of bishops by jurisdiction, but are otherwise self-governing. Abbesses hear confessions (but do not absolve) and dispense blessings on their charges, though they still require the services of a presbyter (i.e., a priest) to celebrate the Divine Liturgy and perform other priestly functions, such as the absolution of a penitent.

Orthodox monastics, in general have little or no contact with the outside world, especially family. The pious family whose child decides to enter the monastic profession understands that their child will become "dead to the world" and therefore be unavailable for social visits.

There are a number of different levels that the nun passes through in her profession:

  • Novice—When one enters a monastery the first three to five years are spent as a novice. Novices may or may not (depending on the abbess's wishes) dress in the black inner robe ( Isorassa); those who do will also usually wear the apostolnik or a black scarf tied over the head (see photo, above). The isorassa is the first part of the monastic " habit" of which there is only one style for Orthodox monastics (this is true in general, there have been a few slight regional variations over the centuries, but the style always seems to precipitate back to a style common in the 3rd or 4th century). If a novice chooses to leave during the novitiate period no penalty is incurred.
  • Rassaphore—When the abbess deems the novice ready, the novice is asked to join the monastery. If she accepts, she is tonsured in a formal service during which she is given the outer robe ( Exorassa) and veil ( Epanokamelavkion) to wear, and (because she is now dead to the world) receives a new name. Nuns consider themselves part of a sisterhood; however, tonsured nuns are usually addressed as "Mother" (in some convents, the title of "Mother" is reserved to those who enter into the next level of Stavrophore).
  • Stavrophore—The next level for monastics takes place some years after the first tonsure when the abbess feels the nun has reached a level of discipline, dedication, and humility. Once again, in a formal service the nun is elevated to the "Little Schema" which is signified by additions to her habit of certain symbolic articles of clothing. In addition, the abbess increases the nun’s prayer rule, she is allowed a stricter personal ascetic practice.
  • Great Schema—The final stage, called "Megaloschemos" or " Great Schema" is reached by nuns whose Abbess feels they have reached a high level of excellence. In some monastic traditions the Great Schema is only given to monks and nuns on their death bed, while in others they may be elevated after as little as 25 years of service.

The Protestant reformers such as Martin Luther said marriage was the normal role for men and women, and shut down the monasteries and convents, often over the protests of the nuns. A modern resurgence of the early Christian Deaconess office for women began in Germany in the 1840s and spread through Scandinavia, Britain and the United States. Lutherans were especially active. The modern movement reached a zenith about 1910, then slowly declined as secularization undercut religiosity in Europe, and the professionalization of nursing and social work offered better career opportunities for young women. A small movement still exists, and its legacy is seen in the names of numerous hospitals.

Anglican Communion

Religious communities throughout England were destroyed by King Henry VIII when he separated the Church of England from the Catholic Church during the English Reformation (see Dissolution of the Monasteries). Monasteries and convents were deprived of their lands and possessions, and monastics were forced to either live a secular life on a pension or flee the country. Manu nuns went to France.

Anglican religious orders are organizations of laity and/or clerg] in the Anglican Communion who live under a common rule. The term "religious orders" must be distinguished from Holy Orders (the sacrament of ordination which bishops, priests, and deacons receive), though many communities do have ordained members.

The structure and function of religious orders in Anglicanism roughly parallels that which exists in Roman Catholicism. Religious communities are divided into orders proper, in which members take solemn vows and congregations, whose members take simple vows.

With the rise of the Catholic Revival and the Oxford Movement in Anglicanism in the early 19th century came interest in the revival of "religious life" in England. Between 1841 and 1855, several religious orders for nuns were founded, among them the Community of St. Mary at Wantage and the Community of St. Margaret at East Grinstead.

In the United States and Canada, the founding of Anglican religious orders of nuns began in 1845 with the Sisterhood of the Holy Communion (now defunct) in New York. In the Episcopal Church in the United States, there are two recognized types of religious communities, called Religious Orders and Christian Communities. The differences are as follows:

A Religious Order of this Church is a society of Christians (in communion with the See of Canterbury) who voluntarily commit themselves for life, or a term of years, to holding their possessions in common or in trust; to a celibate life in community; and obedience to their Rule and Constitution. (Title III, Canon 24, section 1)

A Christian Community of this Church is a society of Christians (in communion with the See of Canterbury) who voluntarily commit themselves for life, or a term of years, in obedience to their Rule and Constitution. (Title III, Canon 24, section 2)

In some Anglican orders, there are sisters who have been ordained and can celebrate the Eucharist.

Fiction and dramatizations featuring

Nuns play an important role in the public's imagination. The following list of notable works where nuns play a major part ranges from A Time for Miracles which is literally hagiography to realistic accounts by Kathryn Hulme and Monica Baldwin to the blatant nunsploitation of Sacred Flesh. All the works use Catholic nuns save Black Narcissus (Anglican). All are outsiders' views with the exceptions of Dead Man Walking, a film based on a non-fiction book of the same title by Helen Prejean, and The Nun's Story, a book by Kathryn Hulme relating the experiences of ex-nun Marie Louise Habets.
