Every legitimate celebration of the Eucharist is regulated by the bishop, to whom is committed the office of offering the worship of Christian religion to the Divine Majesty and of administering it in accordance with the Lord’s commandments and the Church’s laws, as further defined by his particular judgment for his diocese. /…/
Bishops /…/ By the ministry of the word they communicate God’s power to those who believe unto salvation and through the sacraments, the regular and fruitful distribution of which they regulate by their authority, they sanctify the faithful /…/
Bishops, as vicars and ambassadors of Christ, govern the particular churches entrusted to them by their counsel, exhortations, example, and even by their authority and sacred power/…/ This power, which they personally exercise in Christ’s name, is proper, ordinary and immediate, although its exercise is ultimately regulated by the supreme authority of the Church /…/ In virtue of this power, bishops have the sacred right and the duty before the Lord to make laws for their subjects, to pass judgment on them and to moderate everything pertaining to the ordering of worship and the apostolate.
The pastoral office or the habitual and daily care of their sheep is entrusted to them completely; nor are they to be regarded as vicars of the Roman Pontiffs, for they exercise an authority that is proper to them, and are quite correctly called “prelates,” heads of the people whom they govern /…/ But the faithful must cling to their bishop, as the Church does to Christ /…/
Priests, although they do not possess the highest degree of the priesthood, and although they are dependent on the bishops in the exercise of their power, nevertheless they are united with the bishops in sacerdotal dignity./…/
Priests /…/ Associated with their bishop in a spirit of trust and generosity, they make him present in a certain sense in the individual local congregations, and take upon themselves, as far as they are able, his duties and the burden of his care, and discharge them with a daily interest. And as they sanctify and govern under the bishop’s authority, that part of the Lord’s flock entrusted to them they make the universal Church visible in their own locality and bring an efficacious assistance to the building up of the whole body of Christ /…/. On account of this sharing in their priesthood and mission, let priests sincerely look upon the bishop as their father and reverently obey him"
