What of the relationship between lay people and their bishop? Vatican II and the Scriptures suggest a harmonious, loving, and supernatural bond:
[23.] The faithful “should cling to the Bishop as the Church does to Jesus Christ, and as Jesus Christ does to the Father, so that all may be in harmonious unity, and that they may abound to the glory of God”.[Lumen Gentium 27; cf. 2 Cor 4:15] All, including members of Institutes of consecrated life and Societies of apostolic life as well as those of all ecclesial associations and movements of any kind, are subject to the authority of the diocesan Bishop in all liturgical matters,[Cf. Code of Canon Law 397 §1; 678 §1] apart from rights that have been legitimately conceded. To the diocesan Bishop therefore falls the right and duty of overseeing and attending to Churches and oratories in his territory in regard to liturgical matters, and this is true also of those which are founded by members of the above-mentioned institutes or under their direction, provided that the faithful are accustomed to frequent them.[Cf. Code of Canon Law 683 §1]
The bishop oversees lay people in their parishes as well as their groups–that’s canon law.
[24.] It is the right of the Christian people themselves that their diocesan Bishop should take care to prevent the occurrence of abuses in ecclesiastical discipline, especially as regards the ministry of the word, the celebration of the sacraments and sacramentals, the worship of God and devotion to the Saints.[Code of Canon Law 392]
The bishop as liturgical police: that’s canon law. What about the promotion of things that go beyond the basic instructions of how to celebrate Mass?
