The English rendition of the Latin phrase refers to the first two lines of the penultimate stanza of the hymn Pange Lingua Gloriosi Corporis Mysterium written by St. Thomas Aquinas. The phrase translates to “Therefore so great a Sacrament.” It is traditionally sung during Benediction of the Blessed Sacrament in the Roman Catholic Church.
The importance of accurately conveying this phrase lies in its liturgical significance. It introduces a profound contemplation on the Eucharist. An understanding of its Latin origins provides a deeper appreciation of the hymn’s theological weight and historical context within Catholic worship. Its use connects contemporary practice to a rich tradition of sacred music and devotion spanning centuries.
