The bishop is “the steward of the grace of the supreme priesthood,” especially in the Eucharist which he offers personally or whose offering he assures through the priests, his co-workers. the Eucharist is the center of the life of the particular Church. the bishop and priests sanctify the Church by their prayer and work, by their ministry of the word and of the sacraments. They sanctify her by their example, “not as domineering over those in your charge but being examples to the flock.” Thus, “together with the flock entrusted to them, they may attain to eternal life.”
“The bishops, as vicars and legates of Christ, govern the particular Churches assigned to them by their counsels, exhortations, and example, but over and above that also by the authority and sacred power” which indeed they ought to exercise so as to edify, in the spirit of service which is that of their Master.
“The power which they exercise personally in the name of Christ, is proper, ordinary, and immediate, although its exercise is ultimately controlled by the supreme authority of the Church.”But the bishops should not be thought of as vicars of the Pope. His ordinary and immediate authority over the whole Church does not annul, but on the contrary confirms and defends that of the bishops. Their authority must be exercised in communion with the whole Church under the guidance of the Pope.
The Good Shepherd ought to be the model and “form” of the bishop’s pastoral office. Conscious of his own weaknesses, “the bishop . . . can have compassion for those who are ignorant and erring. He should not refuse to listen to his subjects whose welfare he promotes as of his very own children…. the faithful … should be closely attached to the bishop as the Church is to Jesus Christ, and as Jesus Christ is to the Father”:
Let all follow the bishop, as Jesus Christ follows his Father, and the college of presbyters as the apostles; respect the deacons as you do God’s law. Let no one do anything concerning the Church in separation from the bishop.
