51. In the relationship between the Liturgy and popular piety, the opposite phenomenon is also encountered – the importance of popular piety is overestimated practically to the detriment of the Church’s Liturgy.
It has to be said that where such happens, either because of particular circumstances or of a theoretical choice, pastoral deviations emerge. The Liturgy is no longer the “summit towards which the activity of the Church is directed; [and]…the fount from which all her power flows”(SC 10). Rather it becomes a cultic expression extraneous to the comprehension and sensibility of the people which is destined to be neglected, relegated to a secondary role or even become reserved to particular groups.
The diagnosis is accurate, but keep in mind we are a catholic church. Many areas of the world lack a resident clergy to provide the sacraments. Some priests are poor presiders and preachers. When and where there is an effort to bring the liturgy to people, how is the shift to the Mass handled? Do people have confidence in their leadership when good liturgy finally arrives?
