... people are instructed in the truths of faith, and brought to appreciate the inner joys of religion far more effectually by the annual celebration of our sacred mysteries than by any official pronouncement of the teaching of the Church. Such pronouncements usually reach only a few and the more learned among the faithful; feasts reach them all; the former speak but once, the latter speak every year - in fact, forever.And later from Four Benefits of the Liturgy by Dom Gerard Calvet:
-Pope Pius XI Quas Primas
Take a group of Japanese tourists visiting Notre Dame Cathedral in Paris. They look at the height of the stained-glass windows, the harmony of the proportions. Suppose that at that moment, sacred ministers dressed in orphried velvet copes enter in process for solemn Vespers. The visitors watch in silence; they are entranced: beauty has opened its doors to them. Now the Summa Theologica of St. Thomas Aquinas and Notre Dame in Paris are products of the same era. They say the same thing. But who among the visitors has read the Summa of St. Thomas? The same phenomenon is found at all levels. The tourists who visit the Acropolis in Athens are confronted with a civilisation of beauty. But who among them can understand Aristotle?Sacred liturgy is the body language of the Church - the people of God and the Body of Christ.
And so it is with the beauty of the liturgy. More than anything else it deserves to be called the splendour of the truth. It opens to the small and the great alike the treasures of its magnificence: the beauty of psalmody, sacred chants and texts, candles, harmony of movement and dignity of bearing. With sovereign art the liturgy exercises a truly seductive influence on souls, who it touches directly, even before the spirit perceives its influence.
