The Catholic Faith, which is so beautifully expressed in the Holy Mass, was spread by the Apostles and by the early Christian missionaries throughout the Roman Empire. The common language of the Western Roman Empire was Latin, and this became the liturgical language of our rite, the Roman Rite. It has been the consistent teaching of many popes that Latin has special qualities as a language of worship. The use of this ancient language is a safeguard against errors and heresies; it is not subject to constant changes but remains the same for all time. Latin is a symbol of the visible universality and unity of the Church that through the centuries has preserved the bond of unity with our common centre, Rome. Latin, as the language of the Church, unites Catholics from all nations and all centuries.
