The Bishop Chief Shepherd

… For the diocesan bishop, the chief steward of the mysteries of God in the particular church entrusted to his care is the moderator, promoter and guardian of the whole of its liturgical life. In celebrations at which the bishop presides, and especially in the celebration of the Eucharist led by the bishop himself with the presbytery, the deacons, and the people taking part, the mystery of the Church is revealed. For this reason, the solemn celebration of the Masses of this sort must be an example for the entire diocese.

The bishop should, therefore, be determined that the priests, deacons, and the lay Christian faithful grasp ever more deeply the genuine meaning of the rites and liturgical texts and thereby be led to an active and fruitful celebration of the Eucharist. To the same end, he should also be vigilant that the dignity of the celebrations be enhanced. In promoting this dignity, the beauty of the sacred place, of music, and of art should contribute as greatly as possible. [#22]
