Canonical Institutes & Societies

As of Dec. 2013. Not a complete list.

See also: Non-canonical Groups

Listed here are institutes, societies, and communities canonically recognized by the Catholic Church which use the Traditional Roman liturgy, either exclusively or alongside the modern liturgy (as noted). Their respective links lead to external websites. This list is by no means complete, and may be edited in the future.

The Priestly Fraternity of Saint Peter (Fraternitas Sacerdotalis Sancti Petri, F.S.S.P.) is a clerical society of apostolic life of pontifical right. Essentially they are like diocesan priests, but living in community and using only the traditional liturgy. They don't have a particular spirituality (Benedictine, Salesian, etc); each priest is free to choose his own from among the great traditions of the Church. With headquarters in Wigratzbad, Germany and a growing worldwide presence, the FSSP is the largest traditional institute in the Latin Church.

The Institute of Christ the King, Sovereign Priest (Institutum Christi Regis Summi Sacerdotis, I.C.R.S.S.) is another society of apostolic life of pontifical right which uses the traditional Roman liturgy. Their spirituality is derived from St. Benedict, St. Thomas Aquinas, and St. Francis de Sales. With headquarters in Gricigliano, Italy, the ICRSS, too, has a worldwide presence.

The Institute of the Good Shepherd is a France-based society of apostolic life similar to the FSSP and ICRSS, with locations throughout Europe.

The Sons of the Most Holy Redeemer (Filii Sanctissimi Redemptoris, F.Ss.R.) is a clerical institute of diocesan right headquartered in Papa Stronsay, Scotland. Its members are priests using the traditional liturgy. They follow the spirituality of St. Alphonsus Liguori with a contemplative bent.

Communities for Men

Our Lady of Clear Creek Abbey (O.S.B.) is a traditional Benedictine monastery in Hulbert, Oklahoma, USA. It was founded in 1999 by the French Abbey of Notre-Dame de Fontgombault, part of the Solesmes Congregation (federation of monasteries) famous for its 20th-century revival of Gregorian chant. The focus of Clear Creek Abbey is solemn liturgy using the traditional rites.

Monastery of San Benedetto (O.S.B.) in Norcia, Italy is another traditional Benedictine monastery. They are not part of a Congregation (such as Solesmes), but were erected directly under the Abbot Primate of the International Benedictine Confederation. Although they are located in Italy, the community's primary language is English.

Monks of the Most Blessed Virgin Mary of Mount Carmel (M. Carm.) is a monastery in Cody, Wyoming, USA which uses the traditional Carmelite liturgy. Unlike other Carmelite communities of men, they do not engage in apostolic works but live a monastic vocation.

Communities for Women

Priory of Our Lady of Ephesus (O.S.B.) in Gower, Missouri is a traditional Benedictine monastery using the 1962 Mass and Divine Office.

Carmel of Jesus, Mary, and Joseph (O.C.D.) in Valparaiso, Nebraska, USA is a traditional Carmelite monastery associated with the Discalced Carmelite Order. They have daughter houses in Elysburg, Pennsylvania and Oakland, California.

Sisters Adorers of the Royal Heart of Jesus are contemplative nuns associated with the Institute of Christ the King, Sovereign Priest (see above).

Lay Organizations

An organization, unlike an institute or society, does not have vows or a canonical rule of life; its members are united by a common goal.

Una Voce. "The International Una Voce Federation is a lay movement, and its principal aims are to ensure that the Missale Romanum of Pope John XXIII (1962 edition) is maintained in the Church as one of the forms of liturgical celebration, and to safeguard and promote the use of Latin, Gregorian chant and sacred polyphony."

Coalition Ecclesia Dei (North America). "Promoting the Traditional Latin Mass as sanctioned by Summorum Pontificum." [Not to be confused with the Pontifical Commission Ecclesia Dei]

Latin Mass Society of England and Wales. "The Latin Mass Society, founded in 1965, is an association of Catholic faithful dedicated to the promotion of the traditional Latin liturgy of the Catholic Church, the teachings and practices integral to it, the musical tradition which serves it, and the Latin language in which it is celebrated."
