Chapter 1’s next section (yes, this is still chapter 1) treats “Promotion of Liturgical Life in Diocese and Parish” starting with the liturgical role of the bishop and the liturgical life of the cathedral.
The bishop is to be considered as the high priest of his flock, from whom the life in Christ of his faithful is in some way derived and dependent.
Therefore all should hold in great esteem the liturgical life of the diocese centered around the bishop, especially in his cathedral church; they must be convinced that the pre-eminent manifestation of the Church consists in the full active participation of all God’s holy people in these liturgical celebrations, especially in the same eucharist, in a single prayer, at one altar, at which there presides the bishop surrounded by his college of priests and by his ministers (Cf. St. Ignatius of Antioch, To the Smyrnians, 8; To the Magnesians, 7; To the Philadelphians, 4.).
This is our 8th mention of lay participation in the document do far. It is described as “the pre-eminent manifestation” of the faithful. Not art. Not fine music. Not clerical leadership. But lay people praying with their bishop and clergy at liturgy. This isn’t some modern invention; note the footnote from the granddaddy of all Patristics.
It’s hard for me to see the point of the exaggerated importance given to “organic development” given the constant references to the participation of the faithful. Isn’t it clear that the latter had the deep attention of the council bishops, not the former?
