Una Voce (from the Preface of the Most Holy Trinity (with one voice)
is an international federation of associations, founded in 1966 in Rome,
that now includes national associations in seventeen nations on every
continent. It is dedicated to ensuring that the Roman Mass codified by
St. Pius V is maintained as one of the forms of eucharistic worship which
are honored in universal liturgical life, and to restoring the use of Latin,
Gregorian Chant, and sacred polyphony in Catholic liturgy.
Local co-chairs are Christie and Sandy Philp.
