The Foederatio Internationalis Una Voce (a/k/a Una Voce), means “with one voice” and comes from the Preface of the Most Holy Trinity. Una Voce is an international federation, founded in 1966 in Rome that is dedicated to promoting and supporting the celebration of the Usus Antiquior (Tridentine Mass) within the Church, in union with the Holy See and the Bishops united with the Supreme Pontiff of the Church as encouraged through the 2007 Motu Proprio Summorum Pontificum, and the 2011 clarifying document Universae Ecclesiae.
Our Mission is to:
1. Work as a lay movement within the Church for an organic restoration of the liturgy in conformity with it's nature and the Latin Tradition
2. Ensure that the Traditional Latin Mass as codified in the Missale Romanum edited by Pope John XIII is maintained - both in practice and in law - as one of the forms of Eucharistic celebration which is recognized and honored in universal liturgical life.
3. Obtain freedom of use for all other Roman liturgical books enshrining "previous liturgical and disciplinary forms of the Latin tradition" (cf. Ecclesia Dei, n. 5)
4. Safeguard and promote the use of Latin, Gregorian chant and sacred polyphony in the ancient liturgy of the Roman Catholic Church.
5. Encourage, wherever it would benefit the faithful, the establishment of non-territorial parishes and/or chaplancies in which only the liturgical books used in 1962 are employed.
6. Serve the Church by helping the members of the movement, and through their apostolate, all the Christifideles better to understand, and more fruitfully to participate in the Catholic liturgy as a sacred action.
7. Support other practices and customs in accord with Catholic liturgical tradition.
