The Early Church Fathers on various topics: This was a 3700 hour project which included going through 22896 pages of the 38 volume set called Ante Nicene, Nicene, Post Nicene Fathers. I compiled 255 pages of quotes showing that the Early Church was always and completely Catholic. All of these quotes can be verified and found from the source which is free online.
Ignatius of Antioch Epistle to the Romans preface [50-117 AD]
"Ignatius . . . to the church also which holds the presidency, in the location of the country of the Romans, worthy of God, worthy of honor, worthy of blessing, worthy of praise, worthy of success, worthy of sanctification, and, because you hold the presidency in love, named after Christ and named after the Father"
Ignatius of Antioch Epistle to the Romans ch 3 [50-117 AD]
"You [the church at Rome] have envied no one, but others you have taught. I desire only that what you have enjoined in your instructions may remain in force"
Ignatius of Antioch to the Trallians ch 7 (50-117)
He that is within the altar is pure, but he that is without is not pure; that is, he who does anything apart from the bishop, and presbytery, and deacons, such a man is not pure in his conscience.
Ignatius of Antioch to the Ephesians ch 5 (50-117)
For if I in a short time had such converse with your bishop, which was not after the manner of men but in the Spirit, how much more do I congratulate you who are closely joined with him as the Church is with Jesus Christ and as Jesus Christ is with the Father, that all things may be harmonious in unity.
Let no man deceive himself: if any one be not within the altar, he is deprived of the bread of God. For if the prayer of one or two possesses such power, how much more that of the bishop and the whole Church ! He, therefore, that does not assemble with the Church, has even by this manifested his pride, and condemned himself. For it is written, "God resisteth the proud." Let us be careful, then, not to set ourselves in opposition to the bishop, in order that we may be subject to God.
Hermas The Shepherd of Hermas Book I Vision 2 ch 4 [60-120 AD]
"Therefore shall you [Hermas] write two little books and send one to Clement [Bishop of Rome] and one to Grapte. Clement shall then send it to the cities abroad, because that is his duty" (The Shepherd 2:4:3
Irenaeus of Lyons Adversus Haereses Book III Ch 3.2 [120-180 AD]
"But since it would be too long to enumerate in such a volume as this the succession 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 that church, because of its superior origin, all the 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"
Irenaeus of Lyons Adversus Haereses book 3 ch 3.3 [120-180 AD]
….Church founded and organized at Rome by the two most glorious apostles, Peter and Paul; as also means of the successions of the bishops. For it is a matter of necessity that every Church should agree with this Church, on account of its preeminent authority -- that is, the faithful everywhere -- inasmuch as the Apostolic Tradition has been preserved continuously by those who are everywhere. The blessed apostles, then, having founded and built up the Church, committed into the hands of Linus the office of the episcopate. Of this Linus, Paul makes mention in the Epistles to Timothy. To him succeeded Anacletus; and after him, in the third place from the apostles, Clement was allotted the bishopric.…
To this Clement there succeeded Evaristus. Alexander followed Evaristus; then, sixth from the apostles, Sixtus was appointed; after him, Telephorus, who was gloriously martyred; then Hyginus; after him, Pius; then after him, Anicetus. Sorer having succeeded Anicetus, Eleutherius does now, in the twelfth place from the apostles, hold the inheritance of the episcopate. In this order, and by this succession, the ecclesiastical tradition from the apostles, and the preaching of the truth, have come down to us.
Clement of Alexandria Stromata book 6 ch 15 (150-215 ad)
"But all things are right," says the Scripture, observe, according to the ecclesiastical rule, the exposition of the Scriptures explained by Him; and the ecclesiastical rule is the concord and harmony of the law and the prophets in the covenant delivered at the coming of the Lord.
Tertullian Against Marcion Book 4 ch 2 [160-240 AD]
Then, at last, having conferred with the (primitive) authors, and having agreed with them touching the rule of faith, they joined their hands in fellowship, and divided their labours thenceforth in the office of preaching the gospel, so that they were to go to the Jews, and St. Paul to the Jews and the Gentiles. Inasmuch, therefore, as the enlightener of St. Luke himself desired the authority of his predecessors for both his own faith and preaching, how much more may not I require for Luke's Gospel that which was necessary for the Gospel of his master.
Tertullian Against Marcion Book 4 ch 5 [160-240 AD]
The same authority of the apostolic churches will afford evidence to the other Gospels also, which we possess equally through their means, and according to their usage
Tertullian Against Marcion book 4 ch 5 [160-240 AD]
Such are the summary arguments which we use, when we take up arms against heretics for the faith of the gospel, maintaining both that order of periods, which rules that a late date is the mark of forgers, and that authority of churches which lends support to the tradition of the apostles; because truth must needs precede the forgery, and proceed straight from those by whom it has been handed on.
Cyprian of Carthage Epistle 75 par 3 [200-270 AD]
"[T]he 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"
Cyprian of Carthage Epistle 44 par 1, 4 [200-270 AD]
"Cyprian to [Pope] Cornelius, his brother. Greeting. . . . We decided to send and are sending a letter to you from all throughout the province [where I am] so that all our colleagues might give their decided approval and support to you and to your communion, that is, to both the unity and the charity of the Catholic Church"
Cyprian of Carthage Epistle 51 par 1,8 [200-270 AD]
"Cyprian to Antonian, his brother. Greeting ... You wrote ... that I should forward a copy of the same letter to our colleague [Pope] Cornelius, so that, laying aside all anxiety, he might at once know that you held communion with him, that is, with the Catholic Church"
8"Cornelius was made bishop by the decision of God and of his Christ, by the testimony of almost all the clergy, by the applause of the people then present, by the college of venerable priests and good men ... when the place of Fabian, which is the place of Peter, the dignity of the sacerdotal chair, was vacant. Since it has been occupied both at the will of God and with the ratified consent of all of us, whoever now wishes to become bishop must do so outside [the Church]. For he cannot have ecclesiastical rank who does not hold to the unity of the Church"
Cyprian of Carthage Epistle 54 par 14 [200-270 AD]
"With a false bishop appointed for themselves by heretics, they dare even to set sail and carry letters from schismatics and blasphemers to the chair of Peter and to the principal church [at Rome], in which sacerdotal unity has its source"
Cyprian of Carthage Treatise 1 par 4 [200-270 AD]
If any one consider and examine these things, there is no need for lengthened discussion and arguments. There is easy proof for faith in a short summary of the truth. The Lord speaks to Peter, saying, "I say unto thee, that thou art Peter; and upon this rock I will build my Church, and the gates of hell shall not prevail against it. And I will give unto thee the keys of the kingdom of heaven; and whatsoever thou shalt bind on earth shall be bound also in heaven, and whatsoever thou shalt loose on earth shall be loosed in heaven." And again to the same He says, after His resurrection, resurrection, He gives an equal power, and says, "As the Father hath sent me, even so send I you: Receive ye the Holy Ghost: Whose soever sins ye remit, they shall be remitted unto him; and whose soever sins ye retain, they shall be retained;" yet, that He might set forth unity, He arranged by His authority the origin of that unity, as beginning from one. Assuredly the rest of the apostles were also the same as was Peter, endowed with a like partnership both of honour and power; but the beginning proceeds from unity. Which one Church, also, the Holy Spirit in the Song of Songs designated in the person of our Lord, and says, "My dove, my spotless one, is but one. She is the only one of her mother, elect of her that bare her." Does he who does not hold this unity of the Church think that he holds the faith? Does he who strives against and resists the Church trust that he is in the Church, when moreover the blessed Apostle Paul teaches the same thing, and sets forth the sacrament of unity, saying, "There is one body and one spirit, one hope of your calling, one Lord, one faith, one baptism, one God?"
Cyprian of Carthage epistles 46 par 1 (200-270 ad)
Cyprian to Cornelius his brother, greeting. I profess that I both have rendered and do render the greatest thanks without ceasing, dearest brother, to God the Father Almighty, and to His Christ the Lord and our God and Saviour, that the Church is thus divinely protected, and its unity and holiness is not constantly nor altogether corrupted by the obstinacy of perfidy and heretical wickedness.
Cyprian of Carthage epistle 54 par 14 (200-270 ad)
unless perchance the authority of the bishops constituted in Africa seems to a few desperate and abandoned men to be too little, who have already judged concerning them, and have lately condemned, by the gravity of their judgment,
Seventh Council of Carthage (257 ad)
Clarus of Mascula said: The sentence of our Lord Jesus Christ is plain, when He sent His apostles, and accorded to them alone the power given to Him by His Father; and to them we have succeeded, governing the Lord's Church with the same power, and baptizing the faith of believers. And therefore heretics, who neither have power without, nor have the Church of Christ, are able to baptize no one with His baptism.
Eusebius of Caesarea Life of Constantine book 3 ch 62 (265-340 ad)
It was right, therefore, to intimate to your Prudences, that in proposing these men and any others whom you may deem worthy the episcopal dignity, you should decide this question in a manner conformable to the tradition of the apostles. For in that case, your Prudences will be able, according to the rule of the Church and apostolic tradition, to direct this election in the manner which true ecclesiastical discipline shall prescribe.
Eusebius of Caesarea Church History book 10 ch 1 (265-340 ad)
Copy of an epistle in which the emperor commands another synod to be held for the purpose of removing all dissensions among the bishops. [+] "Constantine Augustus to Chrestus, bishop of Syracuse. When some began wickedly and perversely to disagree among themselves in regard to the holy worship and celestial power and Catholic doctrine, wishing to put an end to such disputes among them, I formerly gave command that certain bishops should be sent from Gaul, and that the opposing parties who were contending persistently and incessantly with each other, should be summoned from Africa; that in their presence, and in the presence of the bishop of Rome, the matter which appeared to be causing the disturbance might be examined and decided with all care.
Athanasius Ad Afro Epistola Synodica par 2 (296-373)
But the word of the Lord which came through the ecumenical Synod at Nicaea, abides for ever
Athanasius Apologia Contra Arianos Part 1 par 25(296-373)
Now if you really believe that all Bishops have the same and equal authority, and you do not, as you assert, account of them according to the magnitude of their cities; he that is entrusted with a small city ought to abide in the place committed to him, and not from disdain of his trust to remove to one that has never been put under him; despising that which God has given him, and making much of the vain applause of men. (This is against James White saying large city bishops had more authority)
Gregory Nazianzen Oration 2 par 52 (325-389 ad)
the Twelve Apostles, and their successors, who with many toils and labors exercised their authority, each in his own time;
Basil Letter 125 par 1 (329-379 ad)
Some, moreover, of the impious following of the Libyan Sabellius, who understand hypostasis and substance to be identical, derive ground for the establishment of their blasphemy from the same source, because of its having been written in the creed "if any one says that the Son is of a different substance or hypostasis, the Catholic and Apostolic Church anathematizes him."
Basil Letter 93 par 3 (329-379 ad)
For all these reasons we do indeed desire your help, that, for the future all who confess the apostolic faith may put an end to the schisms which they have unhappily devised, and be reduced for the future to the authority of the Church; that so, once more, the body of Christ may be complete, restored to integrity with all its members.
Ambrose of Milan On the death of Satyrus book 1 par 47 (340-397 ad)
But he was not so eager as to lay aside caution. He called the bishop to him, and esteeming that there can be no true thankfulness except it spring from true faith, he enquired whether he agreed with the Catholic bishops, that is, with the Roman Church?
Ambrose of Milan on Repentance book 1 Ch 7.33 (340-397 ad)
And this confession is indeed rightly made by them, for they have not the succession of Peter, who hold not the chair of Peter, which they rend by wicked schism; and this, too, they do, wickedly denying that sins can be forgiven even in the Church, whereas it was said to Peter: "I will give unto thee the keys of the kingdom of heaven. and whatsoever thou shalt bind on earth shall be bound also in heaven, and whatsoever thou shall loose on earth shall be loosed also in heaven." And the vessel of divine election himself said: "If ye have forgiven anything to any one, I forgive also, for what I have forgiven I have done it for your sakes in the person of Christ." Why, then, do they read Paul's writings, if they think that he has erred so wickedly as to claim for himself the right of his Lord? But he claimed what he had received, he did not usurp that which was not due to him.
Tyrannius Rufinus Commentary on the Apostles Creed par 2 (340-410 ad)
Being all [the apostles] therefore met together, and being filled with the Holy Ghost, they composed, as we have said, this brief formulary [apostles creed] of their future preaching, each contributing his several sentence to one common summary: and they ordained that the rule thus framed should be given to those who believe.
Tyrannius Rufinus Commentary on the Apostles Creed par 3 (340-410 ad)
I think it well to mention that in different Churches some additions are found in this article. This is not the case, however, in the Church of the city of Rome; the reason being, as I suppose, that, on the one hand, no heresy has had its origin there, and, on the other, that the ancient custom is there kept up, that those who are going to be baptized should rehearse the Creed publicly
Tyrannius Rufinus Apology book 2 par 23 (340-410 ad)
and further how he speaks of the city of Rome, which now through the grace of God is reckoned by Christians as their capital
Council of Sardica cannon 5 (344 ad)
And if any one require that his case be heard yet again, and at his request it seem good to move the bishop of Rome to send presbyters a latere, let it be in the power of that bishop, according as he judges it to be good and decides it to be right--that some be sent to be judges with the bishops and invested with his authority by whom they were sent.
Council of Sardica cannon 4 (344 ad)
BISHOP GAUDENTIUS said: If it seems good to you, it is necessary to add to this decision full of sincere charity which thou hast pronounced, that if any bishop be deposed by the sentence of these neighbouring bishops, and assert that he has fresh matter in defence, a new bishop be not settled in his see, unless the bishop of Rome judge and render a decision as to this.
Council of Sardica cannon 3 (344 ad)
But if perchance sentence be given against a bishop in any matter and he supposes his case to be not unsound but good, in order that the question may be reopened, let us, if it seem good to your charity, honour the memory of Peter the Apostle, and let those who gave judgment write to Julius, the bishop of Rome, so that, if necessary, the case may be retried by the bishops of the neighbouring provinces and let him appoint arbiters; but if it cannot be shown that his case is of such a sort as to need a new trial, let the judgment once given not be annulled, but stand good as before.
John Chrysostom Homily 2 on Titus (347-407 ad)
If any is blameless." "In every city," he says, for he did not wish the whole island to be intrusted to one, but that each should have his own charge and care, for thus he would have less labor himself, and those under his rule would receive greater attention, if the Teacher had not to go about to the presidency of many Churches, but was left to be occupied with one only and to bring that into order.
Jerome Against Jovinianus book 1 par 26 (347-420 ad)
But you say, the Church was rounded upon Peter: although elsewhere the same is attributed to all the Apostles, and they all receive the keys of the kingdom of heaven, and the strength of the Church depends upon them all alike, yet one among the twelve is chosen so that when a head has been appointed, there may be no occasion for schism.
Jerome Letter 16 par 2 (347-420 ad)
I meantime keep crying: "He who clings to the chair of Peter is accepted by me."
Jerome Letter 14 par 8 (347-420 ad)
Far be it from me to censure the successors of the apostles, who with holy words consecrate the body of Christ, and who make us Christians. Having the keys of the kingdom of heaven,
Jerome Letter 51 par 2 [347-420 AD]
"I follow no leader but Christ and join in communion with none but your blessedness [Pope Damasus I], that is, with the chair of Peter. I know that this is the rock on which the Church has been built. Whoever eats the Lamb outside this house is profane. Anyone who is not in the ark of Noah will perish when the flood prevails"
Jerome Letter 16 par 2 [347-420 AD]
"The church here is split into three parts, each eager to seize me for its own. . . . Meanwhile I keep crying, 'He that is joined to the chair of Peter is accepted by me!' . . . Therefore, I implore your blessedness [Pope Damasus I] . . . tell me by letter with whom it is that I should communicate in Syria"
Jerome Letter 95 par 2 (347-420 ad)
Being informed, then, by a letter of the aforesaid bishop, we inform your holiness that we in like manner who are set in the city of Rome in which the prince of the apostles, the glorious Peter, first founded the church and then by his faith strengthened it; to the end that no man may contrary to the commandment read these books which we have mentioned, have condemned the same; and have with earnest prayers urged the strict observance of the precepts which God and Christ have inspired the evangelists to teach. We have charged men to remember the words of the venerable apostle Paul, prophetic and full of warning:--"if any than preach any other gospel unto you than that which we have preached unto you, let him be accursed."
Jerome Letter 123 par 10 (347-420 ad)
A great many years ago when I was helping Damasus bishop of Rome with his ecclesiastical correspondence, and writing his answers to the questions referred to him by the councils of the east and west,
Jerome against the Vigilantius par 1 (347-420 ad)
The words may be justly applied to him: "Seed of evil-doers, prepare thy children for the slaughter because of the sins of thy father." Jovinianus, condemned by the authority of the Church of Rome,
Jerome Apology for himself against Rufinius book 1 par 10 (347-420 ad)
The consciences of a great many persons have been wounded by the book which yon have published under the name of the martyr; they give no heed to the authority of the bishops who condemn Origen, since they think that a martyr has praised him.
Jerome Letter 51 par 1 (347-420 ad)
For, although each individual bishop of the Church has under him churches which are placed in his charge, and although no man may stretch himself beyond his measure, yet the love of Christ, which is without dissimulation, is set up as an example to us all; and we must consider not so much the thing done as the time and place, the mode and motive, of doing it.
Augustine of Hippo Sermon 81 on the New Testament par 10 [354-430 AD]
"[On this matter of the Pelagians] two councils have already been sent to the Apostolic See [the bishop of Rome], and from there rescripts too have come. The matter is at an end; would that the error too might be at an end!"
Augustine of Hippo AGAINST THE EPISTLE OF MANICHAEUS CALLED FUNDAMENTAL ch 4.5 [354-430 AD]
For in the Catholic Church, not to speak of the purest wisdom, to the knowledge of which a few spiritual, men attain in this life, so as to know it, in the scantiest measure, deed, because they are but men, still without any uncertainty (since the rest of the multitude derive their entire security not from acuteness of intellect, but from simplicity of faith,)--not to speak of this wisdom, which you do not believe to be in the Catholic Church, there are many other things which most justly keep me in her bosom. The consent of peoples and nations keeps me in the Church; so does her authority, inaugurated by miracles, nourished by hope, enlarged by love, established by age. The succession of priests keeps me, beginning from the very seat of the Apostle Peter, to whom the Lord, after His resurrection, gave it in charge to feed His sheep, down to the present episcopate. And so, lastly, does the name itself of Catholic, which, not without reason, amid so many heresies, the Church has thus retained; so that, though all heretics wish to be called Catholics, yet when a stranger asks where the Catholic Church meets, no heretic will venture to point to his own chapel or house. Such then in number and importance are the precious ties belonging to the Christian name which keep a believer in the Catholic Church, as it is right they should, though from the slowness of our understanding, or the small attainment of our life, the truth may not yet fully disclose itself. But with you, where there is none of these things to attract or keep me, the promise of truth is the only thing that comes into play. Now if the truth is so clearly proved as to leave no possibility of doubt, it must be set before all the things that keep me in the Catholic Church; but if there is only a promise without any fulfillment, no one shall move me from the faith which binds my mind with ties so many and so strong to the Christian religion.
Augustine of Hippo AGAINST THE EPISTLE OF MANICHAEUS CALLED FUNDAMENTAL ch 4.6 [354-430 AD]
For my part, I should not believe the gospel except as moved by the authority of the Catholic Church. So when those on whose authority I have consented to believe in the gospel tell me not to believe in Manichaeus, how can I but consent? Take your choice. If you say, Believe the Catholics: their advice to me is to put no faith in you; so that, believing them, I am precluded from believing you;--If you say, Do not believe the Catholics: you cannot fairly use the gospel in bringing me to faith in Manichaeus; for it was at the command of the Catholics that I believed the gospel;--Again, if you say, You were right in believing the Catholics when they praised the gospel, but wrong in believing their vituperation of Manichaeus: do you think me such a fool as to believe or not to believe as you like or dislike, without any reason? It is therefore fairer and safer by far for me, having in one instance put faith in the Catholics, not to go over to you, till, instead of bidding me believe, you make me understand something in the clearest and most open manner. To convince me, then, you must put aside the gospel. If you keep to the gospel, I will keep to those who commanded me to believe the gospel; and, in obedience to them, I will not believe you at all. But if haply you should succeed in finding in the gospel an incontrovertible testimony to the apostleship of Manichaeus, you will weaken my regard for the authority of the Catholics who bid me not to believe you; and the effect of that will be, that I shall no longer be able to believe the gospel either, for it was through the Catholics that I got my faith in it; and so, whatever you bring from the gospel will no longer have any weight with me. Wherefore, if no clear proof of the apostleship of Manichaeus is found in the gospel, I will believe the Catholics rather than you. But if you read thence some passage clearly in favor of Manichaeus, I will believe neither them nor you: not them, for they lied to me about you; nor you, for you quote to me that Scripture which I had believed on the authority of those liars. But far be it that I should not believe the gospel; for believing it, I find no way of believing you too. For the names of the apostles, as there recorded, do not include the name of Manichaeus. And who the successor of Christ's betrayer was we read in the Acts of the Apostles; which book I must needs believe if I believe the gospel, since both writings alike Catholic authority commends to me.
Augustine of Hippo Confessions Book 9 ch 7.11 [354-430 AD]
and the Holy Scriptures, which the authority of Thy Catholic Church pressed upon me,
Augustine Letter 5 (354-430 ad)
He has bound His people under the new dispensation together in fellowship by sacraments, which are in number very few, in observance most easy, and in significance most excellent, as baptism solemnized in the name of the Trinity, the Communion of His Body and Blood, and such other things as are prescribed in the canonical Scriptures, with the exception of those enactments which were a yoke of bondage to God's ancient people, suited to their state of heart and to the times of the prophets, and which are found in the five books of Moses. As to those other things which we hold on the authority, not of Scripture, but of tradition, and which are observed throughout the whole world, it may be understood that they are held as approved and instituted either by the apostles themselves, or by plenary Councils, whose authority in the Church is most useful, e.g. the annual commemoration, by special solemnities, of the Lord's passion, resurrection, and ascension, and of the descent of the Holy Spirit from heaven, and whatever else is in like manner observed by the whole Church wherever it has been established.
Augustine on the Holy Trinity Book 4 ch 6.10 (354-430 ad)
But those reasons which I have here given, I have either gathered from the authority of the church, according to the tradition of our forefathers, or from the testimony of the divine Scriptures, or from the nature itself of numbers and of similitudes. No sober person will decide against reason, no Christian against the Scriptures, no peaceable person against the church.
Augustine on the Soul and its Origin Book 2 ch 17 (354-430 ad)
The new-fangled Pelagian heretics have been most justly condemned by the authority of catholic councils and of the Apostolic See
Augustine Tractate 50 on the gospel of John (354-430 ad)
For if in Peter's case there were no sacramental symbol of the Church, the Lord would not have said to him, "I will give unto thee the keys of the kingdom of heaven: whatsoever thou shall loose on earth shall be loosed in heaven; and whatsoever thou shalt bind on earth shall be bound in heaven." If this was said only to Peter, it gives no ground of action to the Church. But if such is the case also in the Church, that what is bound on earth is bound in heaven, and what is loosed on earth is loosed in heaven,--for when the Church excommunicates, the excommunicated person is bound in heaven; when one is reconciled by the Church, the person so reconciled is loosed in heaven:--if such, then, is the case in the Church, Peter, in receiving the keys, represented the holy Church.
Augustine Exposition on Psalm 72 par 12 (354-430 ad)
And because there were to be schisms in divers quarters of the world, which would be jealous of the Church Catholic spread abroad in the whole round world, and again those same schisms dividing themselves into the names of men, and by loving the men under whose authority they had been rent, opposing themselves to the glory of Christ which is throughout all lands

For although he deceived the council in Palestine, seemingly clearing himself before it, he entirely failed in imposing on the church at Rome
Augustine On the Grace of Christ and Original Sin book 2 ch 8(354-430 ad)
The venerable Pope Zosimus, keeping in view this deprecatory preamble, dealt with the man, puffed up as he was with the blasts of false doctrine, so as that he should condemn all the objectionable points which had been alleged against him by the deacon Paulinus, and that he should yield his assent to the rescript of the Apostolic See which had been issued by his predecessor of sacred memory.
Augustine On Baptism Against the Donatists book 6 ch 7 par 10 (354-430 ad)
We, therefore, maintaining on the subject of the identity of all baptisms what must be acknowledged everywhere to be the custom of the universal Church, and what is confirmed by the decision of general Councils
Augustine On Baptism Against the Donatists book 2 ch 3 par 4 (354-430 ad)
but that all the letters of bishops which have been written, or are being written, since the closing of the canon, are liable to be refuted if there be anything contained in them which strays from the truth, either by the discourse of some one who happens to be wiser in the matter than themselves, or by the weightier authority and more learned experience of other bishops, by the authority of Councils; and further, that the Councils themselves, which are held in the several districts and provinces, must yield, beyond all possibility of doubt, to the authority of plenary Councils which are formed for the whole Christian world; and that even of the plenary Councils, the earlier are often corrected by those which follow them
Augustine Letter 209 par 8 (354-430 ad)
There are cases on record, in which the Apostolic See, either pronouncing judgment or confirming the judgment of others, sanctioned decisions by which persons, for certain offenses, were neither deposed from their episcopal office nor left altogether unpunished.
Augustine Letter 209 (354-430 ad)
To Caelestine, my lord most blessed, and holy father venerated with all due affection, Augustine sends greetings in the Lord
1. First of all I congratulate you that our Lord God has, as we have heard, established you in the illustrious chair which you occupy without any division among His people. (Caelestine was made pope in 422 Augustine is writing in 423)
Augustine Letter From Augustine to Jerome ch 5 par 9 (354-430 ad)
If, however, perchance it has been from a desire not to enlarge that volume unduly that you refrained from adding to a notice of heretics, the statement of the things in which the Catholic Church has authoritatively condemned them, I beg you not to grudge bestowing on this subject, to which with humility and brotherly love I direct your attention
Augustine Against Petilian the Donatist book 1 ch 26 (354-430 ad)
though the Catholic Church has broken down his defenses by the strongest evidence of truth. For the inheritance of Christ, established in all nations, is secure against heresies which have been shut out from the inheritance;
Augustine On Christian Doctrine Book 2 ch 2 par 2 (354-430 ad)
let the reader consult the rule of faith which he has gathered from the plainer passages of Scripture, and from the authority of the Church, and of which I treated at sufficient length when I was speaking in the first book about things.
Augustine Reply to Faustus the Manichean Book 33 par 9 (354-430 ad)
I close with a word of counsel to you who are implicated in those shocking and damnable errors, that, if you acknowledge the supreme authority of Scripture, you should recognise that authority which from the time of Christ Himself, through the ministry of His apostles, and through a regular succession of bishops in the seats of the apostles, has been preserved to our own day throughout the whole world, with a reputation known to all.
Augustine Reply to Faustus the Manichean Book 11 par 5 (354-430 ad)
there is a distinct boundary line separating all productions subsequent to apostolic times from the authoritative canonical books of the Old and New Testaments. The authority of these books has come down to us from the apostles through the successions of bishops and the extension of the Church, and, from a position of lofty supremacy, claims the submission of every faithful and pious mind.

Vincent of Lerins Commonitory par 84 (390-450 ad)
THE foregoing would be enough and very much more than enough, to crush and annihilate every profane novelty. But yet that nothing might be wanting to such completeness of proof, we added, at the close, the twofold authority of the Apostolic See, first, that of holy Pope Sixtus, the venerable prelate who now adorns the Roman Church; and secondly that of his predecessor, Pope Celestine of blessed memory, which same we think it necessary to insert here also.

Pope Leo the Great Letter 10 [395-461 AD]
But this mysterious function the LORD wished to be indeed the concern of all the apostles, but in such a way that He has placed the principal charge on the blessed Peter, chief of all the Apostles: and from him as from the Head wishes His gifts to flow to all the body: so that any one who dares to secede from Peter's solid rock may understand that he has no part or lot in the divine mystery. For He wished him who had been received into partnership in His undivided unity to be named what He Himself was, when He said: "Thou art Peter, and upon this rock I will build My Church :" that the building of the eternal temple by the wondrous gift of GOD'S grace might rest on Peter's solid rock: strengthening His Church so surely that neither could human rashness assail it nor the gates of hell prevail against it. But this most holy firmness of the rock, reared, as we have said, by the building hand of GOD, a man must wish to destroy in over-weaning 9 wickedness when he tries to break down its power, by favouring his own desires, and not following what he received from men of old:
Pope Leo the Great Letter 14 ch 12 [395-461 AD]
"If in your view, [Anastasius of Thessalonica], in regard to a matter to be handled and decided jointly with your brothers, their decision was other than what you wanted, then let the entire matter, with a record of the proceedings, be referred to us. . . . Although bishops have a common dignity, they are not all of the same rank. Even among the most blessed apostles, though they were alike in honor, there was a certain distinction of power. All were equal in being chosen [to be apostles], but it was given to one to be preeminent over the others. . . . [So today through the bishops] the care of the universal Church would converge in the one see of Peter, and nothing should ever be at odds with this head" (ibid., 14:11).
Pope Gregory the Great Book VII, Letter 40 [540-604 AD]
"Your most sweet holiness, [Bishop Eulogius of Alexandria], has spoken much in your letter to me about the chair of Saint Peter, prince of the apostles, saying that he himself now sits on it in the persons of his successors. And indeed I acknowledge myself to be unworthy . . . I gladly accepted all that has been said, in that he has spoken to me about Peter's chair, who occupies Peter's chair. And, though special honor to myself in no wise delights me . . . who can be ignorant that holy Church has been made firm in the solidity of the prince of the apostles, who derived his name from the firmness of his mind, so as to be called Peter from petra. And to him it is said by the voice of the Truth, 'To you I will give the keys of the kingdom of heaven' [Matt. 16:19]. And again it is said to him, 'And when you are converted, strengthen your brethren' [Luke 22:32]. And once more, 'Simon, son of John, do you love me? Feed my sheep' [John 21:17]"
