23. Let us be clear here: every aspect of the celebration must be carefully tended to (space, time, gestures, words, objects, vestments, song, music…) and every rubric must be observed.
Pope Francis lists the aspects of human interaction here. These are vital, like the rubrics. How liturgy appeals to the senses–sight, sound, etc., is how God communicates to us in the physical universe. The rubrics are important for many reasons, including how they direct the senses be engaged. But the red print is also an intellectual exercise, following the directions given to make the liturgy an expression of a unified and ordered human society. In that unity and order, every believer should have a basic experience that lacks nothing significant from what others know in their worship.
Such attention would be enough to prevent robbing from the assembly what is owed to it; namely, the paschal mystery celebrated according to the ritual that the Church sets down.
And yet, there is something more …
But even if the quality and the proper action of the celebration were guaranteed, that would not be enough to make our participation full.
