Consecrated life, in the
canon law of the Catholic Church, is a stable form of
Christian living by those faithful who are
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
religious vows or other sacred bonds whereby the consecrated persons commit themselves, for the love of God, to observe as binding the
evangelical counsels of chastity, poverty and obedience from the
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 Saint Benedict, ch. 58:17, is analogous to the more usual vow of religious institutes. Consecrated persons are not part of the
hierarchy of the Catholic Church, unless they are also
ordained bishops, priests or deacons.
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. Thus the Church, by virtue of her authority, gladly accepted and approved them."
Consecrated life may be lived either in institutes or individually. While those living it are either clergy (if ordained) or lay people, the state of consecrated life is neither clerical nor lay by nature.
