Consecrated life, in the canonical sense defined by the Catholic Church, is a stable form of Christian living by those faithful who feel called to follow Jesus Christ in a more exacting way recognized by the Church. It "is characterized by the public profession of the evangelical counsels of poverty, chastity, and obedience, in a stable state of life recognized by the Church". The Code of Canon Law defines it as "a stable form of living by which the faithful, following Christ more closely under the action of the Holy Spirit, are totally dedicated to God who is loved most of all, so that, having been dedicated by a new and special title to his honour, to the building up of the Church, and to the salvation of the world, they strive for the perfection of charity in the service of the kingdom of God and, having been made an outstanding sign in the Church, foretell the heavenly glory."
What makes the consecrated life a more exacting way of Christian living is the public vows or other sacred bonds whereby the consecrated persons commit themselves, for the love of God, to observe as binding the counsels of chastity, poverty and obedience from the Christian Gospel, or at least, in the case of consecrated virgins and widows/widowers, a vow of total chastity. The Benedictine vow as laid down in the Rule of St Benedict, ch. 58:17, is analogous to the more usual vow of religious institutes. Consecrated persons are not part of the Catholic Church hierarchy, unless they are also ordained bishops, priests or deacons.
The Catechism of the Catholic Church comments: "From the very beginning of the Church there were men and women who set out to follow Christ with greater liberty, and to imitate him more closely, by practising the evangelical counsels. They led lives dedicated to God, each in his own way. Many of them, under the inspiration of the Holy Spirit, became hermits or founded religious families. These the Church, by virtue of her authority, gladly accepted and approved."
Consecrated life may be lived in institutes, in which the members may be either clergy or laity, or it may be lived individually.
Institutes of consecrated life 
- Religious institute are societies "in which members, according to proper law, pronounce public vows, either perpetual or temporary, which are to be renewed, however, when the period of time has lapsed, and lead a life as brothers or sisters in common".
- Secular institutes, are "institutes of consecrated life in which the Christian faithful, living in the world, strive for the perfection of charity and work for the sanctification of the world especially from within".
Consecrated life outside of institutes 
Besides institutes of consecrated life, the Catholic Church recognizes:
- the eremitic life, also known as the anchoritic life, "by which the Christian faithful devote their life to the praise of God and salvation of the world through a stricter separation from the world, the silence of solitude and assiduous prayer and penance". Catholic Church law recognizes as a hermit "one dedicated to God in a consecrated life if he or she publicly professes the three evangelical counsels, confirmed by a vow or other sacred bond, in the hands of the diocesan bishop, and observes his or her own plan of life under his direction". "They manifest to everyone the interior aspect of the mystery of the Church, that is, personal intimacy with Christ. Hidden from the eyes of men, the life of the hermit is a silent preaching of the Lord, to whom he has surrendered his life simply because he is everything to him. Here is a particular call to find in the desert, in the thick of spiritual battle, the glory of the Crucified One."
- The order of virgins who "expressing the holy resolution of following Jesus more closely, are consecrated to God by the diocesan bishop according to the approved liturgical rite, are mystically betrothed to Christ, the Son of God, and are dedicated to the service of the Church".
- Consecrated widows may be established who, like virgins, "profess chastity apart from the world by a public profession". Pope John Paul II's post-synodal apostolic exhortation Vita consecrata of 25 March 1996 said: "Again being practised today is the consecration of widows, known since apostolic times (cf. 1 Tim 5:5, 9-10; 1 Cor 7:8), as well as the consecration of widowers. These women and men, through a vow of perpetual chastity as a sign of the Kingdom of God, consecrate their state of life in order to devote themselves to prayer and the service of the Church." Although the Latin Church has no specific liturgical rite for the consecration of widows and widowers, the Code of Canons of the Eastern Churches envisages individual eastern Churches choosing to have consecrated widows.
- The Code of Canon Law and the Code of Canons of the Eastern Churches envisage new forms of consecrated life being approved by the Holy See.
Societies of apostolic life 
Societies of apostolic life are dedicated to pursuit of an apostolic purpose, such as educational or missionary work. They "resemble institutes of consecrated life" but are distinct from them. The members do not take religious vows, but live in common, striving for perfection through observing the "constitutions" of the society to which they belong. Some societies of apostolic life, but not all of them, define in their constitutions "bonds" of a certain permanence whereby their members embrace the evangelical counsels. The Code of Canon Law gives for societies of apostolic life regulations much less detailed than for institutes of consecrated life, in many instances simply referring to the constitutions of the individual societies.
Examples of societies of apostolic life are St. Philip Neri's Institute of the Oratory, the Daughters of Charity of St. Vincent de Paul, and the Priests of St. Sulpice, and societies such as the Missionary Society of St. Columban.
Each major development in religious life, particularly in the Latin West, can be seen as a response of the very devout to a particular crisis in the Church of their day.
Eremitic life 
- See also main article Hermit
When Constantine was legalizing Christianity in the Roman Empire in the early 4th century, and the Christian faith became the favoured religion, it lost the self-sacrificing character that had profoundly marked it in the age of Roman persecution. In response to the loss of martyrdom for the sake of the Kingdom of God, some of the very devout men and women left the cities for the testings of the life in the desert that was meant to lead the individual back into a more intimate relationship with God, just like the wandering of the Israelites in the Desert of Sin. The Greek word for desert, eremos, gave this form of religious living the name eremitic (or eremitical) life, and the person leading it the name hermit. St Antony the Great and other early leaders provided guidance to less experienced hermits, and there were soon a large number of Christian hermits, particularly in the desert of Egypt and in parts of Syria.
Though the eremitic life would eventually be overshadowed by the far more numerous vocations to the cenobitic life, it did survive. The Middle Ages saw the emergence of a variant of the hermit, the anchorite; and life in Carthusian and Camaldolese monasteries has an eremitic emphasis. The Greek Orthodox and the Russian Orthodox Churches have their own eremitic traditions, of which Mount Athos is perhaps the most widely heard of today.
In modern times, in the Roman Catholic Church the Code of Canon Law 1983 recognises hermits who - without being members of a religious institute - publicly profess the three evangelical counsels, confirmed by vow or other sacred bond in the hands of their respective diocesan bishop, as Christian faithful that live the consecrated life (cf. canon 603, see also below).
Monastic institutes 
The eremitic life was apparently healthy for some, but led to imbalance in others. St Pachomius, a near contemporary of St Anthony the Great, recognized that some monks needed the guidance and rhythm of a community (cenobium). He is generally credited with founding, in Egypt, the first community of monks, thus launching cenobitic style monasticism.
St Basil in the East in the 4th century, and St Benedict in the West in the 6th century, authored the most influential "rules" for religious living in their areas of the Christian world ("rule" in this sense refers to a collection of precepts, compiled as guidelines for how to follow the spiritual life). They organized a common life with a daily schedule of prayer, work, spiritual reading and rest.
Almost all monasteries in the Eastern Catholic Churches and in the Orthodox Church today follow the Rule of St Basil. The Rule of St Benedict is followed by a variety of orders of monks in the West, including the Benedictines, Cistercians, Trappists, and Camaldolese, and is an important influence in Carthusian life.
Canons regular 
Canons regular are members of certain bodies of priests living in community under the Augustinian Rule (regula in Latin), and sharing their property in common. Distinct from monks, who live a cloistered, contemplative life and sometimes engage in ministry to those from outside the monastery, canons devote themselves to public ministry of liturgy and sacraments for those who visit their churches.
Mendicant institutes 
Around the 13th century during the rise of the medieval towns and cities the mendicant orders developed. While the monastic foundations were rural institutions marked by a retreat from secular society, the mendicants were urban foundations organized to engage secular city life and to meet some of its needs such as education and service to the poor. The five primary mendicant religious Order of the 13th century are the Order of Friars Preachers (the Dominicans), Order of Friars Minor (the Franciscans), Order of the Servants of Mary (Servite Order), Order of St. Augustine or the (Augustinians) and the Order of Our Lady of Mount Carmel (the Carmelites). Unlike the monks and nuns of the earlier orders, the members of the latter orders called their houses convents, rather than monasteries (in English, Dominican convents for men may also be called priories, and Fransciscan and Carmelite convents friaries).
Apostolic institutes 
Until the 16th century recognition was granted only to institutes with solemn vows. Institutes with simple vows arose in the 16th century and increased in number. After at first being merely tolerated, they afterwards obtained approval. They provided specific services or ministries for the Church and society, building schools, hospitals and new missionary enterprises around the world. The period of their greatest growth was in the wake of the French Revolution in early 19th century France and Belgium. These communities were largely founded to Only in 1900 did they obtain full recognition as religious.
The Society of Jesus is an example of an institute that obtained recognition as an "order" with solemn vows, although the members were divided into the professed with solemn vows (a minority) and the "coadjutors" with simple vows. It was founded in the wake of the Protestant Reformation, introducing several innovations designed to meet the demands of the 16th century crisis. It members were freed from the commitments of common life, especially the common prayer, which allowed them to minister individually in distant places. Their unusually long formation, typically thirteen years, prepared them to represent the intellectual tradition of the Church even in isolation.
By the constitution Inter cetera of 20 January 1521, Pope Leo X appointed a rule for tertiaries with simple vows. Under this rule, enclosure was optional, enabling non-enclosed followers of the rule to engage in various works of charity not allowed to enclosed religious. In 1566 and 1568, Pope Pius V rejected this class of institute, but they continued to exist and even increased in number. After at first being merely tolerated, they afterwards obtained approval, finally gaining on 8 December 1900 recognition as religious. 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. The number of these "congregations" (not "orders") increased further in the upheavals brought by the French Revolution and subsequent Napoleonic invasions of other Catholic countries, depriving thousands of monks and nuns of the income that their communities held because of inheritances and forcing them to find a new way of living their religious life
Secular institutes 
Secular institutes have their modern beginnings in 18th century France. During the French Revolution, the government attempted to dechristianise France. The French government had required all priests and bishops to swear an oath of fidelity to the new order or face dismissal from the Church, and had forbidden any form of religious life. Fr Pierre-Joseph Picot de Clorivière, a Jesuit, founded a new society of women, the Daughters of the Heart of Mary (French: Société des Filles du Coeur de Marie). While living a life of perfection, they did not take vows, remaining a secular institute to avoid being considered a religious society by the government. They would eventually receive pontifical institute status in 1957. On 2 February 1947 Pope Pius XII issued the apostolic constitution Provida Mater Ecclesia recognizing secular institutes as "a new category of the state of perfection" Latin: nova categoria status perfectionis. The 1983 Code of Canon Law recognizes secular institutes as a form of consecrated life. They differ from religious institutes in that their members live their lives in the ordinary conditions of the world, either alone, in their families or in fraternal groups. They include, among others, Caritas Christi, The Grail, and the Servite Secular Institute.
