In the Catholic Church, an association of the Christian faithful or simply association of the faithful (Latin: consociationes christifidelium) is a group of baptized persons, clerics or laity or both together, who, according to the 1983 Code of Canon Law, jointly foster a more perfect life or promote public worship or Christian teaching, or who devote themselves to other works of the apostolate.
A 20th-century resurgence of interest in lay societies culminated in the Second Vatican Council, but lay ecclesial societies have long existed in forms such as sodalities (defined in the 1917 Code of Canon Law as associations of the faithful constituted as an organic body),confraternities (similarly defined as sodalities established for the promotion of public worship),medieval communes, and guilds.
Under the 1917 Code of Canon Law, groups of laity that gathered with a common purpose and apostolate were called piae uniones ("pious unions"). With the replacement of the former code by the 1983 Code of Canon Law, they were referred to as associations of the faithful.
Pope John Paul II's apostolic exhortation Christifideles laici of 30 December 1988 spoke of "the flourishing of groups, associations and spiritual movements as well as a lay commitment in the life of the Church" in the years following the Second Vatican Council, "resulting in the birth and spread of a multiplicity of group forms: associations, groups, communities, movements".
A Pastoral Note of the Italian Episcopal Conference issued on 29 April 1993 defined three of the terms:
Associations of the faithful are distinguished from institutes of consecrated life and societies of apostolic life. A group of people who intend to become an institute of consecrated life or society of apostolic life will normally come together at first as an association of the faithful, while awaiting the decision of the bishop, after consulting the Holy See, to establish them in the desired form.
Associations that are approved on an international level are approved by the Dicastery for the Laity, Family and Life (previously by the Pontifical Council for the Laity) and listed in the Directory of International Associations of the Faithful. Associations that exist on a national level are approved by a country's episcopal conference, while those at a diocesan level are approved by the local bishop.
The Franciscan Brothers of Peace, a canonically recognized Public Association of the Faithful was founded in St. Paul, Minnesota, in 1982.

The Amigonian Cooperators was instituted by the Capuchin Tertiaries (Amigonian Friars). Their work among the laity following the charism of the Capuchin Bishop Luis Amigó y Ferrer (1854-1934) dates back to 1937. On 8 December 1992, the Pontifical Council for the Laity recognized the Cooperadores Amigonianos as an international association of the faithful of pontifical right.
The Franciscan Brothers of the Eucharist, founded in 2002 as a companion community to the Franciscan Sisters of the Eucharist, is a Public Association of the Faithful approved by the Archdiocese of Hartford.

Each Brother is assigned to work in a professional field suited to his personal talents and education. They also engage in manual labor, growing vegetable gardens, flower gardens, and raising small farm animals, such as chickens.
