|Fr Joseph Ratzinger in 1971|
The [liturgical] additions of the late Middle Ages were eliminated, and at the same time severe measures were adopted to prevent a rebirth. .... At that time, the fate of the Western liturgy was linked to a set authority, which worked in a strictly bureaucratic way, lacking any historic vision and considering the problem of the liturgy from the sole viewpoint of rubrics and ceremonies, like a problem of etiquette in a saint's court, so to speak.
As a consequence of this link, there was a complete archeologisation of the liturgy, which from the state of a living history was changed into that of pure conservation and, therefore, condemned to an internal death. Liturgy became once and forever a closed construction, firmly petrified. The more it was concerned about the integrity of pre-existent formulas, the more it lost its connection to concrete devotions ....
In this situation, the baroque carved it [the liturgy] superimposing a people's para-liturgy over its true and proper archeologized liturgy. The solemn baroque mass, through the splendor of the orchestra's performance, became a kind of sacred opera, in which the songs of the priest had their role as did the alternating recitals. .... On the ordinary days that did not allow such a performance, devotions that followed the people's mentality were often added to the mass.
