Catechism of the Catholic Church

874 Christ is himself the source of ministry in the Church. He instituted the Church. He gave her authority and mission, orientation and goal:

In order to shepherd the People of God and to increase its numbers without cease, Christ the Lord set up in his Church a variety of offices which aim at the good of the whole body. The holders of office, who are invested with a sacred power, are, in fact, dedicated to promoting the interests of their brethren, so that all who belong to the People of God . . . may attain to salvation. ³⁸⁹

875 "How are they to believe in him of whom they have never heard? And how are they to hear without a preacher? And how can men preach unless they are sent?" ³⁹⁰ No one - no individual and no community - can proclaim the Gospel to himself: "Faith comes from what is heard." ³⁹¹ No one can give himself the mandate and the mission to proclaim the Gospel. The one sent by the Lord does not speak and act on his own authority, but by virtue of Christ's authority; not as a member of the community, but speaking to it in the name of Christ. No one can bestow grace on himself; it must be given and offered. This fact presupposes ministers of grace, authorized and empowered by Christ. From him, bishops and priests receive the mission and faculty ("the sacred power") to act in persona Christi Capitis; deacons receive the strength to serve the people of God in the diaconia of liturgy, word and charity, in communion with the bishop and his presbyterate. The ministry in which Christ's emissaries do and give by God's grace what they cannot do and give by their own powers, is called a "sacrament" by the Church's tradition. Indeed, the ministry of the Church is conferred by a special sacrament.

876 Intrinsically linked to the sacramental nature of ecclesial ministry is its character as service. Entirely dependent on Christ who gives mission and authority, ministers are truly "slaves of Christ," ³⁹² in the image of him who freely took "the form of a slave" for us. ³⁹³ Because the word and grace of which they are ministers are not their own, but are given to them by Christ for the sake of others, they must freely become the slaves of all. ³⁹⁴

877 Likewise, it belongs to the sacramental nature of ecclesial ministry that it have a collegial character. In fact, from the beginning of his ministry, the Lord Jesus instituted the Twelve as "the seeds of the new Israel and the beginning of the sacred hierarchy." ³⁹⁵ Chosen together, they were also sent out together, and their fraternal unity would be at the service of the fraternal communion of all the faithful: they would reflect and witness to the communion of the divine persons. ³⁹⁶ For this reason every bishop exercises his ministry from within the episcopal college, in communion with the bishop of Rome, the successor of St. Peter and head of the college. So also priests exercise their ministry from within the presbyterium of the diocese, under the direction of their bishop.

878 Finally, it belongs to the sacramental nature of ecclesial ministry that it have a personal character. Although Chnst's ministers act in communion with one another, they also always act in a personal way. Each one is called personally: "You, follow me" ³⁹⁷ in order to be a personal witness within the common mission, to bear personal responsibility before him who gives the mission, acting "in his person" and for other persons: "I baptize you in the name of the Father and of the Son and of the Holy Spirit ..."; "I absolve you...."

879 Sacramental ministry in the Church, then, is a service exercised in the name of Christ. It has a personal character and collegial form. This is evidenced by the bonds between the episcopal college and its head, the successor of St. Peter, and in the relationship between the bishop's pastoral responsibility for his particular church and the common solicitude of the episcopal college for the universal Church.

880 When Christ instituted the Twelve, "he constituted [them] in the form of a college or permanent assembly, at the head of which he placed Peter, chosen from among them." ³⁹⁸ Just as "by the Lord's institution, St. Peter and the rest of the apostles constitute a single apostolic college, so in like fashion the Roman Pontiff, Peter's successor, and the bishops, the successors of the apostles, are related with and united to one another." ³⁹⁹

881 The Lord made Simon alone, whom he named Peter, the "rock" of his Church. He gave him the keys of his Church and instituted him shepherd of the whole flock. ⁴⁰⁰ "The office of binding and loosing which was given to Peter was also assigned to the college of apostles united to its head." ⁴⁰¹ This pastoral office of Peter and the other apostles belongs to the Church's very foundation and is continued by the bishops under the primacy of the Pope.

882 The Pope, Bishop of Rome and Peter's successor, "is the perpetual and visible source and foundation of the unity both of the bishops and of the whole company of the faithful." ⁴⁰² "For the Roman Pontiff, by reason of his office as Vicar of Christ, and as pastor of the entire Church has full, supreme, and universal power over the whole Church, a power which he can always exercise unhindered." ⁴⁰³

883 "The college or body of bishops has no authority unless united with the Roman Pontiff, Peter's successor, as its head." As such, this college has "supreme and full authority over the universal Church; but this power cannot be exercised without the agreement of the Roman Pontiff." ⁴⁰⁴

884 "The college of bishops exercises power over the universal Church in a solemn manner in an ecumenical council." ⁴⁰⁵ But "there never is an ecumenical council which is not confirmed or at least recognized as such by Peter's successor." ⁴⁰⁶

885 "This college, in so far as it is composed of many members, is the expression of the variety and universality of the People of God; and of the unity of the flock of Christ, in so far as it is assembled under one head." ⁴⁰⁷

886 "The individual bishops are the visible source and foundation of unity in their own particular Churches." ⁴⁰⁸ As such, they "exercise their pastoral office over the portion of the People of God assigned to them," ⁴⁰⁹ assisted by priests and deacons. But, as a member of the episcopal college, each bishop shares in the concern for all the Churches. ⁴¹⁰ The bishops exercise this care first "by ruling well their own Churches as portions of the universal Church," and so contributing "to the welfare of the whole Mystical Body, which, from another point of view, is a corporate body of Churches." ⁴¹¹ They extend it especially to the poor, ⁴¹² to those persecuted for the faith, as well as to missionaries who are working throughout the world.

887 Neighboring particular Churches who share the same culture form ecclesiastical provinces or larger groupings called patriarchates or regions. ⁴¹³ The bishops of these groupings can meet in synods or provincial councils. "In a like fashion, the episcopal conferences at the present time are in a position to contribute in many and fruitful ways to the concrete realization of the collegiate spirit." ⁴¹⁴

888 Bishops, with priests as co-workers, have as their first task "to preach the Gospel of God to all men," in keeping with the Lord's command. ⁴¹⁵ They are "heralds of faith, who draw new disciples to Christ; they are authentic teachers" of the apostolic faith "endowed with the authority of Christ." ⁴¹⁶

889 In order to preserve the Church in the purity of the faith handed on by the apostles, Christ who is the Truth willed to confer on her a share in his own infallibility. By a "supernatural sense of faith" the People of God, under the guidance of the Church's living Magisterium, "unfailingly adheres to this faith." ⁴¹⁷

890 The mission of the Magisterium is linked to the definitive nature of the covenant established by God with his people in Christ. It is this Magisterium's task to preserve God's people from deviations and defections and to guarantee them the objective possibility of professing the true faith without error. Thus, the pastoral duty of the Magisterium is aimed at seeing to it that the People of God abides in the truth that liberates. To fulfill this service, Christ endowed the Church's shepherds with the charism of infallibility in matters of faith and morals. The exercise of this charism takes several forms:

891 "The Roman Pontiff, head of the college of bishops, enjoys this infallibility in virtue of his office, when, as supreme pastor and teacher of all the faithful - who confirms his brethren in the faith he proclaims by a definitive act a doctrine pertaining to faith or morals.... The infallibility promised to the Church is also present in the body of bishops when, together with Peter's successor, they exercise the supreme Magisterium," above all in an Ecumenical Council. ⁴¹⁸ When the Church through its supreme Magisterium proposes a doctrine "for belief as being divinely revealed," ⁴¹⁹ and as the teaching of Christ, the definitions "must be adhered to with the obedience of faith." ⁴²⁰ This infallibility extends as far as the deposit of divine Revelation itself. ⁴²¹

892 Divine assistance is also given to the successors of the apostles, teaching in communion with the successor of Peter, and, in a particular way, to the bishop of Rome, pastor of the whole Church, when, without arriving at an infallible definition and without pronouncing in a "definitive manner," they propose in the exercise of the ordinary Magisterium a teaching that leads to better understanding of Revelation in matters of faith and morals. To this ordinary teaching the faithful "are to adhere to it with religious assent" ⁴²² which, though distinct from the assent of faith, is nonetheless an extension of it.

893 The bishop is "the steward of the grace of the supreme priesthood," ⁴²³ 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." ⁴²⁴ Thus, "together with the flock entrusted to them, they may attain to eternal life." ⁴²⁵

894 "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. ⁴²⁶

895 "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." ⁴²⁷ 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.

896 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": ⁴²⁸

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. ⁴²⁹
