In Catholicism, an abbess is the female superior of a community of nuns, which is often an abbey.


In the Catholic Church, Eastern Orthodox, Coptic and Anglican abbeys, the mode of election, position, rights, and authority of an abbess correspond generally with those of an abbot. She must be at least 40 years old and have been a nun for 10 years. The age requirement in the Catholic Church has evolved over time, ranging from 30 to 60. The requirement of 10 years as a nun is only 8 in Catholicism. In the rare case of there not being a nun with the qualifications, the requirements may be lowered to 30 years of age and 5 of those in an "upright manner", as determined by the superior. A woman who is of illegitimate birth, is not a virgin, has undergone non-salutory public penance, is a widow, or is blind or deaf, is typically disqualified for the position, saving by permission of the Holy See. The office is elective, the choice being by the secret votes of the nuns belonging to the community. Like an abbot, after being confirmed in her office by the Holy See, an abbess is solemnly admitted to her office by a formal blessing, conferred by the bishop in whose territory the monastery is located, or by an abbot or another bishop with appropriate permission. Unlike the abbot, the abbess receives only the ring, the crosier, and a copy of the rule of the order. She does not receive a mitre as part of the ceremony. The abbess also traditionally adds a pectoral cross to the outside of her habit as a symbol of office, though she continues to wear a modified form of her religious habit or dress, as she is unordained—females cannot be ordained—and so does not vest or use choir dress in the liturgy. An abbess serves for life, except in Italy and some adjacent islands.

Roles and responsibilities

Abbesses are, like abbots, major superiors according to canon law, the equivalents of abbots or bishops. They receive the vows of the nuns of the abbey; they may admit candidates to their order's novitiate; they may send them to study; and they may send them to do pastoral or missionary, or to work or assist—to the extent allowed by canon and civil law—in the administration and ministry of a parish or diocese. They have full authority in its administration.
However, there are significant limitations. They may not administer the sacraments, whose celebration is reserved to bishops, priests, deacons, namely, those in Holy Orders. They may make provision for an ordained cleric to help train and to admit some of their members, if needed, as altar servers, extraordinary ministers of Holy Communion, or lectors—all ministries which are now open to the unordained. They may not serve as a witness to a marriage except by special rescript. They may not administer Penance, Anointing of the Sick, or function as an ordained celebrant or concelebrant of the Mass. They may preside over the Liturgy of the Hours which they are obliged to say with their community, speak on Scripture to their community, and give certain types of blessings not reserved to the clergy. On the other hand, they may not ordinarily preach a sermon or homily, nor read the Gospel during Mass. As they do not receive episcopal ordination in the Catholic, Orthodox and Oriental Churches, they do not possess the ability to ordain others, nor do they exercise the authority they do possess under canon law over any territories outside of their monastery and its territory. There are exigent circumstances, where due to Apostolical privilege, certain Abbesses have been granted rights and responsibilities above the normal, such as the Abbess of the Cistercian Monastery of the Abbey of Santa María la Real de Las Huelgas near Burgos, Spain. Also granted exceptional rights was the Abbess of the Cistercian order in Conversano Italy. She was granted the ability to appoint her own vicar-general, select and approve the confessors, along with the practice of receiving the public homage of her clergy. This practice continued until some of the duties were modified due to an appeal by the clergy to Rome. Finally in 1750, the public homage was abolished.


Historically, in some Celtic monasteries, abbesses presided over joint-houses of monks and nuns, the most famous example being Saint Brigid of Kildare's leadership in the founding of the monastery at Kildare in Ireland. This custom accompanied Celtic monastic missions to France, Spain, and even to Rome itself. In 1115, Robert, the founder of Fontevraud Abbey near Chinon and Saumur, France, committed the government of the whole order, men as well as women, to a female superior.
In Lutheran churches, the title of abbess has in some cases survived to designate the heads of abbeys which since the Protestant Reformation have continued as monasteries or convents. These positions continued, merely changing from Catholic to Lutheran. The first to make this change was the Abbey of Quedlinburg, whose last Catholic Abbess died in 1514. These are collegiate foundations, which provide a home and an income for unmarried ladies, generally of noble birth, called canonesses or more usually Stiftsdamen or Kapitularinnen. The office of abbess is of considerable social dignity, and in the past, was sometimes filled by princesses of the reigning houses. Until the dissolution of Holy Roman Empire and mediatisation of smaller imperial fiefs by Napoleon, the evangelical Abbess of Quedlinburg was also per officio the head of that reichsunmittelbar state. The last such ruling abbess was Sofia Albertina, Princess of Sweden.
In the Hradčany of Prague is a Catholic institute whose mistress is titled an Abbess. It was founded in 1755 by the Empress Maria Theresa, and traditionally was responsible for the coronation of the Queen of Bohemia. The Abbess is required to be an Austrian Archduchess.
During the 7th-10th centuries force began to appear, from papal bulls down to local action, to restrict abbesses' spiritual power: e.g. from blessings, administering of the sacrament, even to the veiling of nuns. Abbesses previously had such authority, only to have these service and administrative acts called "usurpation" increasingly through the 9th-13th centuries. According to reactionaries like Oestereich, the pope categorized these acts of blessing as "unheard of, most indecorous, and highly preposterous."
The Roman Catholic Church has around 200 abbesses at present. The oldest women's abbey in Germany being St. Marienthal Abbey of Cistercian nuns, near Ostritz, established during the early 13th-century.
On September 10, 2018, the priory of Our Lady of Ephesus in Gower, MO was elevated to an Abbey and the prioress, Mother Cecilia Snell, OSB, was consecrated as the first abbess. The Benedictines of Mary Queen of Apostles are a traditional order of Benedictines nuns whose monastery is in the Diocese of Kansas City-St. Joseph.
