Apostolic Tradtion

Irenaeus

"As I said before, the Church, having received this preaching and this faith, although she is disseminated throughout the whole world, yet guarded it, as if she occupied but one house. She likewise believes these things just as if she had but one soul and one and the same heart; and harmoniously she proclaims them and teaches them and hands them down, as if she possessed but one mouth. For, while the languages of the world are diverse, nevertheless, the authority of the tradition is one and the same" (Against Heresies 1:10:2 [A.D. 189]).

"That is why it is surely necessary to avoid them [heretics], while cherishing with the utmost diligence the things pertaining to the Church, and to lay hold of the tradition of truth. . . . What if the apostles had not in fact left writings to us? Would it not be necessary to follow the order of tradition, which was handed down to those to whom they entrusted the churches?" (ibid., 3:4:1).

"It is possible, then, for everyone in every church, who may wish to know the truth, to contemplate the tradition of the apostles which has been made known throughout the whole world. And we are in a position to enumerate those who were instituted bishops by the apostles and their successors to our own times—men who neither knew nor taught anything like these heretics rave about".

"But since it would be too long to enumerate in such a volume as this the successions of all the churches, we shall confound all those who, in whatever manner, whether through self-satisfaction or vainglory, or through blindness and wicked opinion, assemble other than where it is proper, by pointing out here the successions of the bishops of the greatest and most ancient church known to all, founded and organized at Rome by the two most glorious apostles, Peter and Paul, that church which has the tradition and the faith which comes down to us after having been announced to men by the apostles".

"With this church, because of its superior origin, all churches must agree—that is, all the faithful in the whole world—and it is in her that the faithful everywhere have maintained the apostolic tradition" (ibid., 3:3:1–2).

"For even creation reveals Him who formed it, and the very work made suggests Him who made it, and the world manifests Him who ordered it. The Universal [Catholic] Church, moreover, through the whole world, has received this tradition from the Apostles" (Against Heresies 2:9 [A.D. 189]).

"True knowledge is the doctrine of the Apostles, and the ancient constitution of the Church throughout all the world, and the distinctive manifestation of the body of Christ according to the successions of the bishops, by which they have handed down that Church which exists in every place, and has come even unto us, being guarded and preserved, without any forging of Scriptures, by a very complete system of doctrine, and neither addition nor curtailment [in truths which she believes]; and [it consists in] reading [the Word of God] without falsification, and a lawful and diligent exposition in harmony with the Scriptures, both without danger and without blasphemy… "(ibid. 4:33 [A.D. 189]).

Papias

"Papias [A.D. 120], who is now mentioned by us, affirms that he received the sayings of the apostles from those who accompanied them, and he, moreover, asserts that he heard in person Aristion and the presbyter John. Accordingly, he mentions them frequently by name, and in his writings gives their traditions [concerning Jesus]. . . . [There are] other passages of his in which he relates some miraculous deeds, stating that he acquired the knowledge of them from tradition" (fragment in Eusebius, Church History 3:39 [A.D. 312]).

"Whenever anyone came my way, who had been a follower of my seniors, I would ask for the accounts of our seniors: What did Andrew or Peter say? Or Phillip or Thomas or James or John or Matthew, or any of the Lord’s disciples? I also asked: What did Aristion and John the Presbyter, disciples of the Lord say. For, as I see it, it is not so much from books as from the living and permanent voice that I must draw profit" (The Sayings of the Lord [between A.D. 115 and 140] as recorded by Eusebius, Ecclesiastical History, 3:39 [A.D. 325]).

Eusebius of Caesarea

"At that time [A.D. 150] there flourished in the Church Hegesippus, whom we know from what has gone before, and Dionysius, bishop of Corinth, and another bishop, Pinytus of Crete, and besides these, Philip, and Apollinarius, and Melito, and Musanus, and Modestus, and, finally, Irenaeus. From them has come down to us in writing, the sound and orthodox faith received from tradition" (Church History 4:21).

Tertullian

"For wherever both the true Christian rule and faith shall be shown to be, there will be the true Scriptures, and the true expositions, of all the true Christian traditions". (The Prescription of Heretics 19 [A.D. 200]).

Clement of Alexandria

"Well, they preserving the tradition of the blessed doctrine derived directly from the holy apostles, Peter, James, John, and Paul, the sons receiving it from the father (but few were like the fathers), came by God’s will to us also to deposit those ancestral and apostolic seeds. And well I know that they will exult; I do not mean delighted with this tribute, but solely on account of the preservation of the truth, according as they delivered it. For such a sketch as this, will, I think, be agreeable to a soul desirous of preserving from loss the blessed tradition". (Miscellanies 1:1 [A.D. 208]).

Origen

"Seeing there are many who think they hold the opinions of Christ, and yet some of these think differently from their predecessors, yet as the teaching of the Church, transmitted in orderly succession from the Apostles, and remaining in the churches to the present day, is still preserved, that alone is to be accepted as truth which differs in no respect from ecclesiastical and apostolic tradition". (On First Principles Bk. 1 Preface 2 [circa A.D. 225]).

"Although there are many who believe that they themselves hold to the teachings of Christ, there are yet some among them who think differently from their predecessors. The teaching of the Church has indeed been handed down through an order of succession from the apostles and remains in the churches even to the present time. That alone is to be believed as the truth which is in no way at variance with ecclesiastical and apostolic tradition" (The Fundamental Doctrines 1:2 [A.D. 225]).

Cyprian of Carthage

"The Church is one, and as she is one, cannot be both within and without. For if she is with Novatian, she was not with [Pope] Cornelius. But if she was with Cornelius, who succeeded the bishop Fabian by lawful ordination, and whom, beside the honor of the priesthood the Lord glorified also with martyrdom, Novatian is not in the Church; nor can he be reckoned as a bishop, who, succeeding to no one, and despising the evangelical and apostolic tradition, sprang from himself. For he who has not been ordained in the Church can neither have nor hold to the Church in any way" (Letters 75:3 [A.D. 253]).

Decree of Pope St. Stephen I

"Let no innovation be introduced, but let that beobserved which is handed down to us by tradition." (Letter to the Church of Africa 257 A.D.)

Eusebius

"While [Ignatius of Antioch] was making the journey through Asia under the strictest military guard, he strengthened the diocese in each city where he stayed by spoken sermons and exhortations, and he especially exhorted them above all to be on their guard against the heresies which then for the first time were prevalent and he urged them to hold fast to the tradition of the Apostles to which he thought it necessary, for securities sake, to give form by written testimony" (Ecclesiastical History, 3:36 [A.D. 325]).

Athanasius

"Again we write, again keeping to the apostolic traditions, we remind each other when we come together for prayer; and keeping the feast in common, with one mouth we truly give thanks to the Lord. Thus giving thanks unto him, and being followers of the saints, ‘we shall make our praise in the Lord all the day,’ as the psalmist says. So, when we rightly keep the feast, we shall be counted worthy of that joy which is in heaven" (Festal Letters 2:7 [A.D. 330]).

"But you are blessed, who by faith are in the Church, dwell upon the foundations of the faith, and have full satisfaction, even the highest degree of faith which remains among you unshaken. For it has come down to you from apostolic tradition, and frequently accursed envy has wished to unsettle it, but has not been able" (ibid., 29).

"Without prefixing Consulate, month, and day, [the Fathers] wrote concerning Easter, "It seemed good as follows," for it did then seem good that there should be a general compliance; but about the faith they wrote not, "It seemed good" but, "Thus believes the Catholic Church"; and thereupon they confessed how they believed, in order to show that their own sentiments were not novel, but Apostolic; and what they wrote down was no discovery of theirs, but is the same as was taught by the Apostles" (Letter on the Councils of Ariminum and Seleucia [A.D. 359]).

Basil the Great

"Of the dogmas and messages preserved in the Church, some we possess from written teaching and others we receive from the tradition of the apostles, handed on to us in mystery. In respect to piety, both are of the same force. No one will contradict any of these, no one, at any rate, who is even moderately versed in matters ecclesiastical. Indeed, were we to try to reject unwritten customs as having no great authority, we would unwittingly injure the gospel in its vitals; or rather, we would reduce [Christian] message to a mere term" (The Holy Spirit 27:66 [A.D. 375]).

Epiphanius of Salamis

"It is needful also to make use of tradition, for not everything can be gotten from sacred Scripture. The holy apostles handed down some things in the scriptures, other things in tradition" (Medicine Chest Against All Heresies 61:6 [A.D. 375]).

Jerome

Don’t you know that the laying on of hands after baptism and then the invocation of the Holy Sirit is a custom of the Churches? Do you demand Scripture proof? You may find it in the Acts of the Apostles. And even if it did not rest on the authority of Scripture the consensus of the whole world in this respect would have the force of a command. For many other observances of the Churches, which are do to tradition, have acquired the authority of the written law (The Dialogue Against the Luciferians 8 [A.D. 382]).

Augustine

"The custom [of not rebaptizing converts] . . . may be supposed to have had its origin in apostolic tradition, just as there are many things which are observed by the whole Church, and therefore are fairly held to have been enjoined by the apostles, which yet are not mentioned in their writings" (On Baptism, Against the Donatists 5:23[31] [A.D. 400]).

"But the admonition that he [Cyprian] gives us, ‘that we should go back to the fountain, that is, to apostolic tradition, and thence turn the channel of truth to our times,’ is most excellent, and should be followed without hesitation" (ibid., 5:26[37]).

"But in regard to those observances which we carefully attend and which the whole world keeps, and which derive not from Scripture but from Tradition, we are given to understand that they are recommended and ordained to be kept, either by the apostles themselves or by plenary [ecumenical] councils, the authority of which is quite vital in the Church" (Letter to Januarius [A.D. 400]).

John Chrysostom

"[Paul commands,] ‘Therefore, brethren, stand fast and hold the traditions which you have been taught, whether by word or by our letter’ [2 Thess. 2:15]. From this it is clear that they did not hand down everything by letter, but there is much also that was not written. Like that which was written, the unwritten too is worthy of belief. So let us regard the tradition of the Church also as worthy of belief. Is it a tradition? Seek no further" (Homilies on Second Thessalonians [A.D. 402]).

Vincent of Lerins

"With great zeal and closest attention, therefore, I frequently inquired of many men, eminent for their holiness and doctrine, how I might, in a concise and, so to speak, general and ordinary way, distinguish the truth of the Catholic faith from the falsehood of heretical depravity.

"I received almost always the same answer from all of them—that if I or anyone else wanted to expose the frauds and escape the snares of the heretics who rise up, and to remain intact and in sound faith, it would be necessary, with the help of the Lord, to fortify that faith in a twofold manner: first, of course, by the authority of divine law [Scripture] and then by the tradition of the Catholic Church.

"Here, perhaps, someone may ask: ‘If the canon of the scriptures be perfect and in itself more than suffices for everything, why is it necessary that the authority of ecclesiastical interpretation be joined to it?’ Because, quite plainly, sacred Scripture, by reason of its own depth, is not accepted by everyone as having one and the same meaning. . . .
"Thus, because of so many distortions of such various errors, it is highly necessary that the line of prophetic and apostolic interpretation be directed in accord with the norm of the ecclesiastical and Catholic meaning" (The Notebooks [A.D. 434]).

"I have often then inquired earnestly and attentively of very many men eminent for sanctity and learning, how and by what sure and so to speak universal rule I may be able to distinguish the truth of Catholic faith from the falsehood of heretical pravity; and I have always, and in almost every instance, received an answer to this effect: That whether I or any one else should wish to detect the frauds and avoid the snares of heretics as they rise, and to continue sound and complete in the Catholic faith, we must, the Lord helping, fortify our own belief n two ways: first, by the authority of the Divine Law, and then, by the Tradition of the Catholic Church" (Commonitory 2 [A.D. 434]).

Theodoret

"I have ever kept the faith of the Apostles undefiled… So have I learnt not only from the Apostles and the Prophets but also from the interpreters of their writings, Ignatius, Eustathius, Athanasius, Basil, Gregory, John, and the rest of the lights of the world; and before these from the holy Fathers in council at Nicaea, whose confession of the faith I preserve in its integrity, like an ancestral inheritance [styling corrupt and enemies of the truth all who dare to transgress its decrees]" (Letters no. 89 [circa A.D. 443]).

Pope Agatho

"The holy Church of God . . . has been established upon the firm rock of this Church of blessed Peter, the prince of the apostles, which by his grace and guardianship remains free from all error, [and possesses that faith that] the whole number of rulers and priests, of the clergy and of the people, unanimously should confess and preach with us as the true declaration of the apostolic tradition, in order to please God and to save their own souls" (Letter read at fourth session of III Constantinople [A.D. 680]).
