O Key of David, and Sceptre of the house of Israel; that openest, and no man shutteth, and shuttests, and no man openeth: come and bring the prisoner out of the prison house, and him that sitteth in darkness, and the shadow of death.
The beauty of the liturgy . . . more than anything else it deserves to be called the splendor 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, whom it touches directly, even before the spirit perceives its influence.
-- Dom Gerard Calvet, OSB (1927-2008)
