The episcopal college and its head, the Pope
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.” 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.”
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. “The office of binding and loosing which was given to Peter was also assigned to the college of apostles united to its head.” 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.” “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.”
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.”
884 “The college of bishops exercises power over the universal Church in a solemn manner in an ecumenical council.” But “there never is an ecumenical council which is not confirmed or at least recognized as such by Peter’s successor.”
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.”

The teaching office
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. 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.”
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.”
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. When the Church through its supreme Magisterium proposes a doctrine “for belief as being divinely revealed,” and as the teaching of Christ, the definitions “must be adhered to with the obedience of faith.” This infallibility extends as far as the deposit of divine Revelation itself.
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” which, though distinct from the assent of faith, is nonetheless an extension of it.
Lumen Gentium (Dogmatic Constitution on the Church: 21 November 1964)
22. Just as, in accordance with the Lord’s decree, St Peter and the rest of the apostles constitute a unique 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. Indeed, the very ancient discipline whereby the bishops installed throughout the whole world lived in communion with one another and with the Roman Pontiff in a bond of unity, charity and peace; likewise the holding of councils in order to settle conjointly, in a decision rendered balanced and equitable by the advice of many, all questions of major importance; all this points clearly to the collegiate character and structure of the episcopal order, and the holding of ecumenical councils in the course of the centuries bears this out unmistakably. Indeed, pointing to it also quite clearly is the custom, dating from very early times, of summoning a number of bishops to take part in the elevation of one newly chosen to the highest sacerdotal office. One is constituted a member of the episcopal body in virtue of the sacramental consecration and by the hierarchical communion with the head and members of the college.
The college or body of bishops has for all that no authority unless united with the Roman Pontiff, Peter’s successor, as its head, whose primatial authority, let it be added, over all, whether pastors or faithful, remains in its integrity. For the Roman Pontiff, by reason of his office as Vicar of Christ, namely, 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. The order of bishops is the successor to the college of the apostles in their role as teachers and pastors, and in it the apostolic college is perpetuated. Together with their head, the Supreme Pontiff, and never apart from him, they have supreme and full authority over the universal Church; but this power cannot be exercised without the agreement of the Roman Pontiff. The Lord made Peter alone the rock-foundation and the holder of the keys of the Church (cf. Mt. 16:18-19), and constituted him shepherd of his whole flock (cf. Jn. 21:15 ff.). It is clear, however, that the office of binding and loosing which was given to Peter (Mt. 16:19), was also assigned to the college of the apostles united to its head (Mt. 18:18; 28:16-20). This college, in so far as it is composed of many members, is the expression of the multifariousness 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. In it the bishops, whilst loyally respecting the primacy and pre-eminence of their head, exercise their own proper authority for the good of their faithful, indeed even for the good of the whole Church, the organic structure and harmony of which are strengthened by the continued influence of the Holy Spirit. The supreme authority over the whole Church, which this college possesses, is exercised in a solemn way in an ecumenical council. There never is an ecumenical council which is not confirmed or at least recognized as such by Peter’s successor.
And it is the prerogative of the Roman Pontiff to convoke such councils, to preside over them and to confirm them. This same collegiate power can be exercised in union with the pope by the bishops while living in different parts of the world, provided the head of the college summon them to collegiate action, or at least approve or freely admit the corporate action of the unassembled bishops, so that a truly collegiate act may result.

25. Among the more important duties of bishops that of preaching the Gospel has pride of place. For the bishops are heralds of the faith, who draw new disciples to Christ; they are authentic teachers, that is, teachers endowed with the authority of Christ, who preach the faith to the people assigned to them, the faith which is destined to inform their thinking and direct their conduct; and under the light of the Holy Spirit they make that faith shine forth, drawing from the storehouse of revelation new things and old (cf. Mt. 13:52); they make it bear fruit and with watchfulness they ward off whatever errors threaten their flock (cf. 2 Tim. 4-14). Bishops who teach in communion with the Roman Pontiff are to be revered by all as witnesses of divine and Catholic truth; the faithful, for their part, are obliged to submit to their bishops’ decision, made in the name of Christ, in matters of faith and morals, and to adhere to it with a ready and respectful allegiance of mind. This loyal submission of the will and intellect must be given, in a special way, to the authentic teaching authority of the Roman Pontiff, even when he does not speak ex cathedra in such wise, indeed, that his supreme teaching authority be acknowledged with respect, and sincere assent be given to decisions made by him, conformably with his manifest mind and intention, which is made known principally either by the character of the documents in question, or by the frequency with which a certain doctrine is proposed, or by the manner in which the doctrine is formulated.
Although the bishops, taken individually, do not enjoy the privilege of infallibility, they do, however, proclaim infallibly the doctrine of Christ on the following conditions: namely, when, even though dispersed throughout the world but preserving for all that amongst themselves and with Peter’s successor the bond of communion, in their authoritative teaching concerning matters of faith and morals, they are in agreement that a particular teaching is to be held definitively and absolutely.  This is still more clearly the case when, assembled in an ecumenical council, they are, for the universal Church, teachers of and judges in matters of faith and morals, whose decisions must be adhered to with the loyal and obedient assent of faith.
This infallibility, however, with which the divine redeemer wished to endow his Church in defining doctrine pertaining to faith and morals, is co-extensive with the deposit of revelation, which must be religiously guarded and loyally and courageously expounded. 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 (cf. Lk. 22:32)–he proclaims in an absolute decision a doctrine pertaining to faith or morals. For that reason his definitions are rightly said to be not reformable by their very nature and not by reason of the assent of the Church, is as much as they were made with the assistance of the Holy Spirit promised to him in the person of blessed Peter himself; and as a consequence they are in no way in need of the approval of others, and do not admit of appeal to any other tribunal. For in such a case the Roman Pontiff does not utter a pronouncement as a private person, but rather does he expound and defend the teaching of the Catholic faith as the supreme teacher of the universal Church, in whom the Church’s charism of infallibility is present in a singular way. The infallibility promised to the Church is also present in the body of bishops when, together with Peter’s successor, they exercise the supreme teaching office. Now, the assent of the Church can never be lacking to such definitions on account of the same Holy Spirit’s influence, through which Christ’s whole flock is maintained in the unity of the faith and makes progress in it.
Furthermore, when the Roman Pontiff, or the body of bishops together with him, define a doctrine, they make the definition in conformity with revelation itself, to which all are bound to adhere and to which they are obliged to submit; and this revelation is transmitted integrally either in written form or in oral tradition through the legitimate succession of bishops and above all through the watchful concern of the Roman Pontiff himself- and through the light of the Spirit of truth it is scrupulously preserved in the Church and unerringly explained. The Roman Pontiff and the bishops, by reason of their office and the seriousness of the matter, apply themselves with zeal to the work of inquiring by every suitable means into this revelation and of giving apt expression to its contents; they do not, however, admit any new public revelation as pertaining to the divine deposit of faith.
[read at the closing ceremonies of Dec. 8 by Archbishop Pericle Felici, general secretary of the council]
At last all which regards the holy ecumenical council has, with the help of God, been accomplished and all the constitutions, decrees, declarations and votes have been approved by the deliberation of the synod and promulgated by us. Therefore we decided to close for all intents and purposes, with our apostolic authority, this same ecumenical council called by our predecessor, Pope John XXIII, which opened October 11, 1962, and which was continued by us after his death.
We decided moreover that all that has been established synodally is to be religiously observed by all the faithful, for the glory of God and the dignity of the Church and for the tranquillity and peace of all men. We have approved and established these things, decreeing that the present letters are and remain stable and valid, and are to have legal effectiveness, so that they be disseminated and obtain full and complete effect, and so that they may be fully convalidated by those whom they concern or may concern now and in the future; and so that, as it be judged and described, all efforts contrary to these things by whomever or whatever authority, knowingly or in ignorance be invalid and worthless from now on.
Given in Rome at St. Peter’s, under the [seal of the] ring of the fisherman, Dec. 8, on the feast of the Immaculate Conception of the Blessed Virgin Mary, the year 1965, the third year of our pontificate.
SECTION I: THE SUPREME AUTHORITY OF THE CHURCH
CHAPTER I : THE ROMAN PONTIFF AND THE COLLEGE OF BISHOPS
Can. 330 Just as, by the decree of the Lord, Saint Peter and the rest of the Apostles form one College, so for a like reason the Roman Pontiff, the successor of Peter, and the Bishops, the successors of the Apostles, are united together in one.
ARTICLE 1: THE ROMAN PONTIFF
Can. 331 The office uniquely committed by the Lord to Peter, the first of the Apostles, and to be transmitted to his successors, abides in the Bishop of the Church of Rome. He is the head of the College of Bishops, the Vicar of Christ, and the Pastor of the universal Church here on earth. Consequently, by virtue of his office, he has supreme, full, immediate and universal ordinary power in the Church, and he can always freely exercise this power.
[ . . . ]
Can. 333 §2 The Roman Pontiff, in fulfilling his office as supreme Pastor of the Church, is always joined in full communion with the other Bishops, and indeed with the whole Church. He has the right, however, to determine, according to the needs of the Church, whether this office is to be exercised in a personal or in a collegial manner.
§3 There is neither appeal nor recourse against a judgement or a decree of the Roman Pontiff.
[ . . . ]
ARTICLE 2: THE COLLEGE OF BISHOPS
Can. 336 The head of the College of Bishops is the Supreme Pontiff, and its members are the Bishops by virtue of their sacramental consecration and hierarchical communion with the head of the College and its members. This College of Bishops, in which the apostolic body abides in an unbroken manner, is, in union with its head and never without this head, also the subject of supreme and full power over the universal Church.
Can. 337 §1 The College of Bishops exercises its power over the universal Church in solemn form in an Ecumenical Council.
§2 It exercises this same power by the united action of the Bishops dispersed throughout the world, when this action is as such proclaimed or freely accepted by the Roman Pontiff, so that it becomes a truly collegial act.
§3 It belongs to the Roman Pontiff to select and promote, according to the needs of the Church, ways in which the College of Bishops can exercise its office in respect of the universal Church in a collegial manner.
Can. 338 §1 It is the prerogative of the Roman Pontiff alone to summon an Ecumenical Council, to preside over it personally or through others, to transfer, suspend or dissolve the Council, and to approve its decrees.
[ . . . ]
Can. 341 §1 The decrees of an Ecumenical Council do not oblige unless they are approved by the Roman Pontiff as well as by the Fathers of the Council, confirmed by the Roman Pontiff and promulgated by his direction.
§2 If they are to have binding force, the same confirmation and promulgation is required for decrees which the College of Bishops issues by truly collegial actions in another manner introduced or freely accepted by the Roman Pontiff.
- We profess that we hold and preach the faith which from the beginning was given to the apostles by our great God and Saviour Jesus Christ, and was proclaimed by them to the whole world. The holy Fathers professed, explained and handed on this faith to the holy Church, particularly those Fathers who took part in the four holy Councils which we follow and accept entirely for everything . . .
The Council of Lateran (649): Canon 17
Whosoever does not confess, in accordance with the holy Fathers, by word and from heart, really and in truth, to the last word, all that has been handed down and proclaimed to the holy, catholic and apostolic Church by the holy Fathers and by the five venerable General Councils, condemnatus sit. (Denzinger 517)
Profession of Faith of Pius IV (Bull Iniunctum Nobis: 1564)
- I unhesitatingly accept and profess also all other things transmitted, defined and declared by the sacred canons and the ecumenical Councils, especially by the most Holy Council of Trent . . . (Denzinger 1869)
