Especially in the liturgy language plays an important role. The language of the liturgy cannot be identical with the language employed in everyday life, since liturgical language is characterized by the recognition that Holy Mass is a mystery, i.e., the faithful approach the Lord with dignity and reverence, an attitude which should also find an expression in the general prayers recited outside the context of the Mass.
The liturgy's dignity is based first on its preservation of Tradition and second on its universal binding force. In the Roman Catholic Church, both are realized best in and by the Latin language, the official language of the Church. This does not exclude the possibility of praying also in the vernacular; however, one has to keep in mind that in its essence, even the best translation of a given text is merely a report on its content with vague concepts.

"Authentic art,... by its play of forms, shades and lights, by melody in song or finely tuned vocal modulations in speech, makes thought transparent and harmonic and interprets or stirs the sentiments and passions in the hearts of men....
What is decisive, however, is that dramatic art always builds on the foundation of the God-given moral laws and ever has the aim of providing symbols and examples which raise people up on high, that is, ultimately lead them closer to God."(54)
On this basis the human quest for divine truth in this world should be depicted also in literature (lyrics, epics, drama, film, etc.) if linguistic and intellectual tools are to come to their appropriate unfolding and if speech and gesture, history, tradition, and imagination are to be properly united.
Realized in symbols, allegories, and parables, poetry fulfills the task of Christian proclamation in a particularly aesthetic way.
Just as our Christian life cannot have any other content, any other aim, than the ever so weak, the ever so inadequate, the almost unrecognizable imitation of our Lord, so Christian drama can receive its orientation and distinctive character only from this very imitation of Christ.
The revival of religious theater, of the mystery and Corpus Christi plays, has a high significance for the exercise of the apostolate, as these plays relive the events of the gospels and permit an application to modern life.(55)
