Reformed Fathers

What

The Council of Trent claimed there was a "universal consensus of the Fathers" in full alignment with Catholic teaching, but the historical record tells a different story. The Church Fathers disagreed with each other on almost every topic, including the nature of the Eucharist, the role of tradition, and the meaning of Peter's primacy. This site is a collection of those dissenting voices, not necessarily to prove one side exhaustively, but rather to show the diversity of patristic thinking in a way that allows us to approach these topics with more humility.

Why

The Church Fathers matter because they are the earliest witnesses to how the apostolic tradition was understood in the generations immediately following the apostles. When we want to know what the New Testament authors meant — how their words were heard, how their practices were received — the Fathers are irreplaceable. They are not infallible, and they frequently contradict one another. But they are the closest we can get to the apostolic mind outside of Scripture itself. Historically, Protestants have been well versed in church history and championed patristic scholarship. However, this has faded in recent generations. Hopefully, this site encourages interest in the early church and provides grounding for the beliefs of your church.

Eucharist Requires Faith

While Eucharistic theology is diverse among the Fathers, several theologians disagreed with Rome that Christ is objectively present for anyone who partakes. Instead, the benefit of the Eucharist is tied to faith. Receiving the bread and cup without faith does not confer grace. This is most compatible with the Reformed view of Spiritual presence, where reception is tied to the Holy Spirit.

Augustine of Hippo

Tractates on the Gospel of John, 25.12 (c. 415 AD)

"To eat that meat which endures to everlasting life is to believe in Him. Why do you make ready your tooth and your belly? Only believe, and you have eaten already."

Augustine of Hippo

Tractates on the Gospel of John (c. 415 AD)

"He that eats within, not without; who eats in his heart, not who presses with his teeth."

Augustine of Hippo

Tractates on the Gospel of John (c. 415 AD)

"Consequently, he that dwells not in Christ and in whom Christ dwells not, doubtless neither eats His flesh nor drinks His blood."

Augustine of Hippo

City of God, 21.25 (c. 426 AD)

"For he who is not in the body of Christ is not to be considered to eat the body of Christ."

Origen of Alexandria

Commentary on Matthew, XI.14 (c. 248 AD)

"Which seems to me to be thus: as it is not the meat but the conscience of him who eats with doubt which defiles him… there is advantage to him who uses it, when with undefiled mind and pure conscience he partakes of the bread… [the Eucharist] goes into the belly and is cast out into the draught, but in respect of the prayer which comes upon it, according to the proportion of the faith, becomes a benefit."

Origen of Alexandria

Commentary on John 6, as cited by Thomas Cranmer, A True and Catholic Doctrine of the Eucharist (1550)

"The Word was made flesh and very meat, which whoso eateth shall surely live for ever; which no evil man can eat. For if it could be that he that continueth evil might eat the Word made flesh, seeing that he is the Word and bread of life, it should not have been written, 'Whosoever eateth this bread, shall live for ever.'"

Spiritual Presence

While some Fathers may have emphasized Christ's localized presence in the Eucharist, many others taught a spiritual presence. The emphasis here is that Christ's humanity is truly human, therefore it is finite and locally present in heaven. Therefore, the Eucharist connects us to Christ through the Holy Spirit, where we are lifted to heaven.

Ambrose of Milan

On the Mysteries, Chapter 9 (c. 390 AD)

"That sacrament is Christ, because it is the Body of Christ — it is therefore not bodily food but spiritual."

Athanasius of Alexandria

Fragment on the Eucharist (c. 350 AD)

"But this, and the blood from it, shall be given to you spiritually at My hands as meat, so as to be imparted spiritually in each one, and to become for all a preservative to resurrection of life eternal."

Cyprian of Carthage

As cited by Thomas Cranmer, Defence of the True and Catholic Doctrine

"This bread is the food of the soul, and not the meat of the belly."

Augustine of Hippo

Tractates on the Gospel of John, 25.12 (c. 415 AD)

"To eat then that meat which endures to everlasting life is to believe in Him. Why do you make ready your tooth and your belly? Only believe, and you have eaten already."

Augustine of Hippo

Sermon on Psalm 98 (c. 415 AD)

"How shall I take hold of the absent? How shall I stretch up my hand into heaven, and take hold of one who is sitting there? Stretch up your faith, and you have got hold."

Cyril of Jerusalem

On the Mysteries (c. 350 AD)

"Christ on a certain occasion discoursing with the Jews said, 'Except ye eat My flesh and drink My blood, ye have no life in you.' They, not having heard His saying in a spiritual sense, were offended, and went back, supposing that He was inviting them to eat flesh."

John Chrysostom

On The Priesthood, III (c. 390 AD)

"For when you see the Lord sacrificed, and laid upon the altar… are you not, on the contrary, straightway translated to Heaven?"

Eucharist Remains Bread

The Catholic Church teaches a view of the Eucharist called transubstantiation, where the substance of the Eucharist becomes Christ's body, but the accidents of bread remain. Technically speaking, this means that the Eucharist looks, feels, and tastes like bread, but it is not bread in any sense of the word. The very nature of the bread has transformed into Christ. However, the Church Fathers were adamant that the bread remains bread in substance after consecration.

Irenaeus of Lyons

Against Heresies (c. 180 AD)

"No longer common bread, but the Eucharist, consisting of two realities, earthly and heavenly."

Ambrose of Milan

On the Mysteries (c. 390 AD)

"The bread and wine in the Sacraments remain still the same they were before."

Pope Gelasius I

On the Two Natures in Christ (c. 494 AD)

"Yet the substance or nature of the bread and wine does not cease."

Theodoret of Cyrus

Dialogues, Eranistes (c. 448 AD)

"After the consecration the mystical signs do not cast off their own proper nature; for they remain still in their former substance, form, and kind."

Theodoret of Cyrus

Dialogues, Eranistes (c. 448 AD)

"There ceaseth not to be still the substance of bread, and nature of wine."

John Chrysostom

As cited by Thomas Cranmer, A True and Catholic Doctrine of the Eucharist (1550)

"The bread, before it be sanctified, is called bread; but when it is sanctified by the means of the priest, it is delivered from the name of bread, and is exalted to the name of the Lord's body, although the nature of bread doth still remain."

Eucharistic Grace

In Catholic theology, there is an emphasis on the quantification of grace, where the Eucharist offers one of several unique graces in the Christian life. This can create anxiety as Christians attempt to 'collect' each grace, as well as lead to legalism surrounding which Eucharists are to be considered valid. However, many Fathers spoke of Scripture and the ongoing act of faith as participating in Christ's body and blood as well, which is reflected in the Reformed doctrine of union with Christ. The entirety of Christ is offered through each means of grace to reassure us of our gifts already received by faith.

Origen of Alexandria

Commentary on Numbers, Homily 16 (c. 240 AD)

"We are said to drink the blood of Christ, not only by the sacramental rite, but also when we receive His word, in which is life."

Jerome

Commentarius in Ecclesiasten V.3 (c. 388 AD)

"To nourish ourselves with his flesh and drink his blood — not only in the Eucharist but also in reading sacred Scripture."

Jerome

Translating Origen's Commentary on Isaiah (c. 395 AD)

"When we hear the word of God, Christ's body and blood are being poured into our ears."

Ambrose of Milan

Various homilies (c. 385 AD)

"[Your] souls I would without hesitation call altars, on which Christ is daily offered."

Augustine of Hippo

Tractates on the Gospel of John, 25.12 (c. 415 AD)

"To eat then that meat which endures to everlasting life is to believe in Him. Why do you make ready your tooth and your belly? Only believe, and you have eaten already."

Eucharistic Sacrifice

Rome believes that the Eucharist is a re-presentation of Christ's sacrifice. While many Reformed theologians likewise emphasize that Christ is re-presented (in the sense that the Holy Spirit connects us to Christ's eternal sacrifice), the Reformers emphasized that this was not the primary understanding among the Church Fathers. The patristic witness taught that the Eucharist ('thanksgiving' in greek) is a sacrifice of praise and thanksgiving, just as Romans 12 tells us to offer our worship as a living sacrifice.

The Didache

Chapter 14 (c. 80–120 AD)

"But every Lord's Day gather yourselves together, and break bread, and give thanksgiving after having confessed your transgressions, that your sacrifice may be pure."

Irenaeus of Lyons

Against Heresies, IV.17 (c. 180 AD)

"Now we make offering to Him, not as though He stood in need of it, but rendering thanks for His gift, and thus sanctifying what has been created."

Baptism Requires Faith

The Church Fathers nearly unanimously argued for some form of baptismal regeneration, where baptism truly participates in salvation. However, the specific mechanism of this regeneration is not unanimous. Several Church Fathers emphasized that the efficacy of baptism is tied to faith, which is not the Roman teaching of Ex Opere Operato, where all baptisms regenerate.

Tertullian

On Baptism, Chapter 6 (c. 203 AD)

"Not that in the water we obtain the Holy Spirit, but being cleansed in the water under the angel, we are prepared for the Holy Spirit."

Tertullian

De Paenitentia (On Repentance), c. 203 AD

"That baptismal washing is a sealing of faith, which faith is begun and is commended by the faith of repentance… We are not washed so that we may cease sinning, but because we have ceased, since in heart we have been bathed already. For the first baptism of a learner is this, a perfect fear; thenceforward, in so far as you have understanding of the Lord faith is sound, the conscience having once for all embraced repentance."

Cyril of Jerusalem

Catechetical Lectures (c. 350 AD)

"[Baptism without faith:] for the water will receive, but the Spirit will not accept you."

Cyril of Jerusalem

Catechetical Lectures (c. 350 AD)

"Once Simon Magus also entered into the water; he was baptized but not enlightened. And while he plunged his body into the water, he did not enlighten his heart with the Spirit. And his body descended and ascended. But his soul was not buried with Christ, nor raised up."

Cyril of Jerusalem

Catechetical Lectures (c. 350 AD)

"Neither does he that is baptized with water, but not found worthy of the Spirit, receive the grace in perfection."

Gregory of Nyssa

Great Catechism (c. 385 AD)

"If the washing is applied to the body while the soul has not expelled the stains of its passions… that in these cases the water is water, since the gift of the Holy Spirit is nowhere manifest in what takes place."

Scripture Has Primacy

Many Church Fathers explicitly placed Scripture above all other authorities, including councils, bishops, traditions, and their own writings.

Gregory of Nyssa

De Cognitione Dei (380 AD)

"We make Sacred Scripture the rule and the norm of every doctrine. We necessarily fix our eyes upon it and approve only what may be made to harmonize with the intent of these writings."

Gregory of Nyssa

De Cognitione Dei (380 AD)

"Whatever is not supported by the testimony of Scripture we reject as false."

Theodoret of Cyrus

Dialogue, Eranistes (448 AD)

"Do not, I beg you, bring in human reasoning. I shall yield to Scripture alone."

Cyril of Jerusalem

Catechetical Lectures (c. 350 AD)

"For concerning the divine and holy mysteries of the Faith, not even a casual statement must be delivered without the Holy Scriptures; nor must we be drawn aside by mere plausibility and artifices of speech. Even to me, who tell you these things, give not absolute credence, unless you receive the proof of the things which I announce from the Divine Scriptures. For this salvation which we believe depends not on ingenious reasoning, but on demonstration of the Holy Scriptures."

Irenaeus of Lyons

Against Heresies (c. 180 AD)

"Suppose there arise a dispute relative to some important question among us, should we not have recourse to the most ancient Churches with which the apostles held constant intercourse, and learn from them what is certain and clear in regard to the present question? For how should it be if the apostles themselves had not left us writings? Would it not be necessary, [in that case,] to follow the course of the tradition which they handed down to those to whom they did commit the Churches?"

Basil of Caesarea

c. 370 AD

"We are not content simply because this is the tradition of the Fathers. What is important is that the Fathers followed the meaning of Scripture."

Gregory of Nyssa

On the Holy Trinity (380 AD)

"Let the inspired Scriptures then be our umpire, and the vote of truth will be given to those whose dogmas are found to agree with the Divine words."

John of Damascus

Exposition of the Orthodox Faith (c. 700 AD)

"It is impossible either to say or fully to understand anything about God beyond what has been divinely proclaimed to us, whether told or revealed, by the sacred declarations of the Old and New Testaments."

Basil of Caesarea

Letter 189.3 (375 AD)

"Therefore let God-inspired Scripture decide between us; and on whichever side be found doctrines in harmony with the word of God, in favor of that side will be cast the vote of truth."

Augustine of Hippo

Reply to Faustus the Manichaean, Book 23, Chapter 9 (400 AD)

"In the matters of which we are now treating, only the canonical writings have any weight with us."

Augustine of Hippo

Letter to Jerome (No. 82) (405 AD)

"I have learned to yield this respect and honor only to the canonical books of Scripture: of these alone do I most firmly believe that the authors were completely free from error."

Athanasius of Alexandria

De Synodis, Chapter 6

"Vainly then do they run about with the pretext that they have demanded Councils for the faith's sake; for divine Scripture is sufficient above all things; but if a Council be needed on the point, there are the proceedings of the Fathers, for the Nicene Bishops did not neglect this matter, but stated the doctrine so exactly, that persons reading their words honestly, cannot but be reminded by them of the religion towards Christ announced in divine Scripture."

Scripture Is Sufficient

While Protestants believe that apostolic traditions and customs of the church exist, they are not essential to salvation. Everything necessary for salvation is found in Scripture.

Hippolytus of Rome

Against Noetus (c. 200 AD)

"There is, brethren, one God, the knowledge of whom we gain from the Holy Scriptures, and from no other source."

Athanasius of Alexandria

Against the Heathen (360 AD)

"The holy and inspired Scriptures are fully sufficient for the proclamation of the truth."

Basil of Caesarea

Epistle (c. 375 AD)

"Enjoying as you do the consolation of the holy Scriptures, you stand in need neither of my assistance nor of that of anybody else… You have the all-sufficient counsel and guidance of the Holy Spirit to lead you to what is right."

Cyril of Jerusalem

Catechetical Lecture 4.17 (c. 350 AD)

"Believe me not in whatsoever I shall simply deliver, unless thou find the things which I shall speak demonstrated out of the Holy Scriptures. For our salvation ought not to rest upon human testimony, but upon the demonstration of the Holy Scriptures."

Cyril of Jerusalem

Catechetical Lectures (4th century)

"For since all cannot read the Scriptures, some being hindered as to the knowledge of them by want of learning, and others by a want of leisure, in order that the soul may not perish from ignorance, we comprise the whole doctrine of the Faith in a few lines [the Creed]. This summary I wish you both to commit to memory when I recite it and to rehearse it with all diligence among yourselves, not writing it out on paper, but engraving it by the memory upon your heart."

Gregory of Nyssa

De Cognitione Dei (380 AD)

"We are not entitled to such license, namely, of affirming whatever we please. For we make Sacred Scripture the rule and the norm of every doctrine. Upon that we are obliged to fix our eyes, and we approve only whatever can be brought into harmony with the intent of these writings."

John Chrysostom

Homily 33 on Acts (c. 400 AD)

"There comes a heathen and says, I wish to become a Christian, but I know not whom to join… if we bid you believe the Scriptures, and these are simple and true, the decision is easy for you. If any agree with the Scriptures, he is a Christian; if any fight against them, he is far from this rule."

Gregory of Nyssa

De Cognitione Dei, pg. 46:1115 (380 AD)

"Whatever is not supported by the testimony of Scripture we reject as false."

Augustine of Hippo

Of the Good of Widowhood, Chapter 2 (414 AD)

"What more shall I teach you than what we read in the apostles? For Holy Scripture fixes the rule for our doctrine, lest we dare be wiser than we ought. Therefore I should not teach you anything else except to expound to you the words of the Teacher."

Augustine of Hippo

Reply to Faustus the Manichaean, Book 13, Chapter 5 (400 AD)

"This shows that the established authority of Scripture must outweigh every other; for it derives new confirmation from the progress of events which happen, as Scripture proves, in fulfillment of the predictions made so long before their occurrence."

Cyril of Alexandria

De Sacrosancta Trinitate, Chapter 1 (425 AD)

"All things, therefore, that have been delivered to us by the Law, and Prophets, and Apostles, we receive, and acknowledge, and confess; and beyond these, we seek not to know anything. For it is impossible for us to say, or at all think anything concerning God, beyond what has been divinely declared by the divine oracles of the Old and New Testament."

Jerome

Against Helvidius, Chapter 21 (390 AD)

"But as we do not deny what is written, so we do reject what is not written."

Augustine of Hippo

On Christian Doctrine 2.9 (396 AD)

"Among the things that are plainly laid down in Scripture are to be found all matters that concern faith and the manner of life."

Scripture Is Clear Without Tradition

Some argue that Scripture is obscure and requires an authoritative tradition and teaching office to interpret it. However, this is not the belief of the Church Fathers, who taught that Scripture is plain, clear, and understandable by all through careful reading.

Irenaeus of Lyons

Against Heresies, II.27.2 (c. 180 AD)

"Since, therefore, the entire Scriptures, the prophets, and the Gospels, can be clearly, unambiguously, and harmoniously understood by all… they proclaim one only God, to the exclusion of all others, formed all things by His word."

Irenaeus of Lyons

Against Heresies (c. 180 AD)

"And they [heretics] assert that the Scriptures are ambiguous, and that the truth cannot be extracted from them by those who are ignorant of tradition."

Clement of Alexandria

The Stromata (c. 200 AD)

"Sometimes heretics quote from the prophetic Scriptures, but they misuse them in several ways: first, they don't make use of all the Scriptures. Second, when they do cite a passage, they don't quote it in its entirety… they gather a few expressions here and there, not looking to the meaning, but making use of the mere words, while altering the meaning."

Clement of Alexandria

The Stromata, Book 6, Chapter 15

"And this signified that the Scripture is clear to all, when taken according to the bare reading; and that this is the faith which occupies the place of the rudiments."

John Chrysostom

Homilies on the Second Epistle of Paul to the Thessalonians, Homily 3

"All things are clear and open that are in the divine Scriptures; the necessary things are all plain."

Augustine of Hippo

On Christian Doctrine, Book 2, Chapter 9, Section 14

"For among the things that are plainly laid down in Scripture are to be found all matters that concern faith and the manner of life."

Tradition Is Fallible

While tradition has an essential role in the Christian life, the Church Fathers believed that tradition — including their own writings and those of other bishops — can err and be corrected by Scripture.

Augustine of Hippo

On the Unity of the Church, c. 405 AD

"We ought to find the Church, as the Head of the Church, in the Holy Canonical Scriptures, not to inquire for it in the various reports, and opinions, and deeds, and words, and visions of men."

Basil of Caesarea

De Spiritu Sancto, c. 375 AD

"We are not content simply because this is the tradition of the Fathers. What is important is that the Fathers followed the meaning of Scripture."

Jerome

Commentary on Galatians, c. 387 AD

"I place the Apostles in a distinct rank from all other writers — for as for them, they always speak truth — but as for those other, they err sometimes, like men as they were."

Augustine of Hippo

On Baptism, Against the Donatists, Book 2 (c. 400 AD)

"The sacred canon of Scripture… stands so absolutely in a superior position to all later letters of the bishops, that about it we can have no doubt or disputation at all — whether what is written in it is true and right; but 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 in them which strays from the truth — and so are even plenary Councils."

Augustine of Hippo

Letter 82 to Jerome (405 AD)

"As to all other writings, in reading them, however great the superiority of the authors to myself in sanctity and learning, I do not accept their teaching as true on the mere ground of the opinion being held by them; but only because they have succeeded in convincing my judgment of its truth either by means of these canonical writings themselves, or by arguments addressed to my reason."

Augustine of Hippo

Letter 148.15 (c. 400 AD)

"For the reasonings of any men whatsoever, even though they be Catholics, and of high reputation, are not to be treated by us in the same way as the canonical Scriptures are treated. We are at liberty, without doing any violence to the respect which these men deserve, to condemn and reject anything in their writings, if perchance we shall find that they have entertained opinions differing from that which others or we ourselves have, by the divine help, discovered to be the truth. I deal thus with the writings of others, and I wish my intelligent readers to deal thus with mine."

Augustine of Hippo

Against the Epistle of Parmenianus, c. 400 AD

"Let no one say to me, What hath Donatus said, what hath Parmanian said, or Pontius, or any of them. For we must not allow even Catholic bishops, if at any time, perchance, they are in error, to hold any opinion contrary to the Canonical Scriptures of God."

Augustine of Hippo

c. 400 AD

"As regards our writings, which are not a rule of faith or practice, but only a help to edification, we may suppose that they contain some things falling short of the truth in obscure and recondite matters, and that these mistakes may or may not be corrected in subsequent treatises. For we are of those of whom the apostle says: 'And if you be otherwise minded, God shall reveal even this unto you' (Philippians 3:15). Such writings are read with the right of judgment, and without any obligation to believe. In order to leave room for such profitable discussions of difficult questions, 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 Apocrypha

Protestants are often charged with removing books from the Bible. However the early church did not have a consensus on the canon. A few in the West but several more in the East disputed the deuterocanonical books: some appreciated their value to the Church but did not consider them Scripture; others encouraged Christians to have nothing to do with them. It's worth noting that these quotes do not support a canon identical to the Protestant churches, as they often add or omit a book or two. However, there is a precedent for the sixty-six book canon when reading their works. It's also worth noting that some fathers described a twenty-two book canon in reference to the Hebrew bible that Protestants use — they simply counted the books differently at the time to tie it to the Hebrew alphabet.

Cyril of Jerusalem

Catechetical Lectures

"Pray, read none of the apocryphal writings: for why do you, who know not those which are acknowledged among all, trouble yourself in vain about those which are disputed? Read the Divine Scriptures, the twenty-two books of the Old Testament, these that have been translated by the Seventy-two Interpreters."

Athanasius of Alexandria

Festal Letter 39 (367 AD)

"[lists the canon]…Thus far constitutes the Old Testament…there are other books besides these not indeed included in the Canon, but appointed by the Fathers to be read by those who newly join us, and who wish for instruction in the word of godliness. The Wisdom of Solomon, and the Wisdom of Sirach, and Esther, and Judith, and Tobit, and that which is called the Teaching of the Apostles, and the Shepherd. But the former, my brethren, are included in the Canon, the latter being [merely] read; nor is there in any place a mention of apocryphal writings."

Jerome

Prologus Galeatus

"And so there are also twenty-two books of the Old Testament [protestant canon counted differently]…we may be assured that what is not found in our list must be placed amongst the Apocryphal writings. Wisdom, therefore, which generally bears the name of Solomon, and the book of Jesus, the Son of Sirach, and Judith, and Tobias, and the Shepherd are not in the canon. The first book of Maccabees I have found to be Hebrew, the second is Greek, as can be proved from the very style."

Jerome

Prologue to the Books of Solomon

"Therefore, just as the Church also reads the books of Judith, Tobias, and the Maccabees, but does not receive them among the canonical Scriptures, so also one may read these two scrolls for the strengthening of the people, (but) not for confirming the authority of ecclesiastical dogmas."

Hilary of Poitiers

Exposition of Psalm 15

"The reason for reckoning twenty-two books of the Old Testament is that this corresponds with the number of the [Hebrew] letters."

Eusebius of Caesarea

Ecclesiastical History

"When expounding the first Psalm, he [Origen] gives a catalogue of the sacred Scriptures of the Old Testament as follows: 'It should be stated that the canonical books, as the Hebrews have handed them down, are twenty-two; corresponding with the number of their letters.'"

John of Damascus

On the Orthodox Faith

"Observe, further, that there are two and twenty books of the Old Testament, one for each letter of the Hebrew tongue. For there are twenty-two letters of which five are double, and so they come to be twenty-seven. For the letters Caph, Mere, Nun, Pe, Sade are double. And thus the number of the books in this way is twenty-two, but is found to be twenty-seven because of the double character of five."

Gregory of Nazianzus

Carmina Dogmatica, Book I, Section I

"Receive the number and names of the holy books… These twenty-two books of the Old Testament are counted according to the twenty-two letters of the Jews…"

Melito of Sardis

As cited by Eusebius, Ecclesiastical History, Book 4, Section 26

"Melito to Onesimus his brother: I have accurately learned the books of the Old Testament. Their names are as follows: Five books of Moses: Genesis, Exodus, Leviticus, Numbers, and Deuteronomy. Joshua, Judges, Ruth. Four books of Kings [two of Samuel and two of Kings], two of Paralipomenon [Chronicles]. The Psalms of David, the Proverbs of Solomon (which is also Wisdom), Ecclesiastes, the Song of Songs, Job. Of the prophets, Isaiah, Jeremiah; and of the twelve prophets, one book; Daniel, Ezekiel, Esdras."

Council of Laodicea

Canon 59–60 (c. 363 AD)

"Let no private psalms nor any uncanonical books be read in church, but only the canonical ones of the New and Old Testament…These are all the books of Old Testament appointed to be read: 1, Genesis of the world; 2, The Exodus from Egypt; 3, Leviticus; 4, Numbers; 5, Deuteronomy; 6, Joshua, the son of Nun; 7, Judges, Ruth; 8, Esther; 9, Of the Kings, First and Second; 10, Of the Kings, Third and Fourth; 11, Chronicles, First and Second; 12, Esdras, First and Second; 13, The Book of Psalms; 14, The Proverbs of Solomon; 15, Ecclesiastes; 16, The Song of Songs; 17, Job; 18, The Twelve Prophets; 19, Isaiah; 20, Jeremiah, and Baruch, the Lamentations, and the Epistle; 21, Ezekiel; 22, Daniel."

Epiphanius of Salamis

Panarion

"For if you were begotten from the Holy Spirit and instructed in the prophets and apostles, you must have gone through (the record) from the beginning of the genesis of the world until the times of Esther in twenty-seven books of the Old Covenant, which are numbered as twenty-two."

Tradition Is One Deposit

Rome emphasizes that sacred traditions are a second part of the deposit of faith given by the apostles, meaning there are infallible and necessary doctrines not in scripture that are only found in the church. However, typically when the Church Fathers use the word "tradition," they are using it interchangeably with the term "scripture," "the gospel," or the Christian belief in general.

Irenaeus of Lyons

Against Heresies, Book 3, Chapter 1

"That alone is the true life-giving faith, which the church received from the apostles and passed on to her children… We have learned from none others the plan of our salvation, than from those through whom the Gospel has come down to us, which they did at one time proclaim in public, and, at a later period, by the will of God, handed down to us in the Scriptures, to be the ground and pillar of our faith."

Irenaeus of Lyons

Against Heresies, Book 3

"Suppose there arise a dispute relative to some important question among us, should we not have recourse to the most ancient Churches with which the apostles held constant intercourse, and learn from them what is certain and clear in regard to the present question? For how should it be if the apostles themselves had not left us writings? Would it not be necessary, [in that case,] to follow the course of the tradition which they handed down to those to whom they did commit the Churches?"

Irenaeus of Lyons

Against Heresies

"To which course many nations… carefully preserving the ancient tradition, believing in one God, the Creator of heaven and earth, and all things therein, by means of Christ Jesus, the Son of God; who, because of His surpassing love towards His creation, condescended to be born of the virgin, He Himself uniting man through Himself to God, and having suffered under Pontius Pilate, and rising again, and having been received up in splendour, shall come in glory."

Tertullian

Prescription Against Heretics

"They then in like manner founded churches in every city, from which all the other churches, one after another, derived the tradition of the faith, and the seeds of doctrine, and are every day deriving them, that they may become churches."

Apostolic Succession of Doctrine

Rome claims that a valid church only exists through apostolic succession. However, several Church Fathers taught that the true church is found in the gathering of believers under correct doctrine. Apostolic succession is not described as a divine ordination but rather as a mechanism for Christians to know which churches were orthodox and which were heretical by tracing their presbyters to the apostles.

Jerome

Commentary on Ezekiel (c. 411 AD)

"The Church does not consist in walls, but in the truths of her teachings. The Church is there where there is true faith. As a matter of fact, fifteen and twenty years ago, all the church buildings belonged to heretics [namely the Arians], for heretics twenty years ago were in possession of them; but the true Church was there where the true faith was."

Clement of Alexandria

Stromata, 7.5 (c. 198 AD)

"For it is not now the place, but the assemblage of the elect, that I call the Church."

Gregory of Nazianzus

On His Own Life (c. 382 AD)

"For unity in doctrine deserves unity in office; and a rival teacher sets up a rival throne; the one is a successor in reality, the other in name only."

Tertullian

On the Prescription of Heretics, Chapter 32 (c. 200 AD)

"Let them [heretics] unfold the roll of their bishops, running down in due succession from the beginning in such a manner that that first bishop of theirs shall be able to show for his ordainer and predecessor some one of the apostles or of apostolic men — a man, moreover, who continued steadfast with the apostles. For this is the manner in which the apostolic churches transmit their registers… should they even effect the contrivance, they will not advance a step."

Tertullian

On the Prescription of Heretics, Chapter 21 (c. 200 AD)

"We hold communion with the apostolic churches because our doctrine is in no respect different from theirs. This is our witness of apostolicity."

Tertullian

On the Prescription of Heretics (c. 200 AD)

"To this test, therefore will they be submitted for proof by those churches, who, although they derive not their founder from apostles or apostolic men (as being of much later date, for they are in fact being founded daily), yet, since they agree in the same faith, they are accounted as not less apostolic because they are akin in doctrine."

Augustine of Hippo

On the Unity of the Church, c. 405 AD

"Whoever dissents from the sacred Scriptures, even if they are found in all places in which the church is designated, are not the church."

Augustine of Hippo

On the Unity of the Church, Chapter 47

"All such things then removed, let them demonstrate their Church, if they can, not in the speeches and murmurs of African, not in the councils of their bishops, not in the epistles of whatever debates, not in false signs and prodigies, since we are prepared and cautioned against them by the word of the Lord, but in the precept of the law, in the predictions of the prophets, in the songs of the psalms, in the utterances of the one shepherd himself, in the preaching of the evangelists, that is in all the canonical authority of the holy books, and not such that they might gather and cite things that are spoken obscurely or ambiguously or metaphorically which anyone might interpret according to his own opinion as he wishes. Such things cannot be properly understood and explained unless first those things that are said most openly are held with a strong faith."

Ambrose of Milan

Exposition of the Holy Gospel according to Saint Luke

"So the faith of the church must be sought first and foremost. If Christ is to dwell in a house, it undoubtedly must be chosen. But lest an unbelieving people or a heretical teacher deface its home, the church is commanded that the fellowship of heretics be avoided and the synagogue shunned....Any church which rejects faith and does not possess the foundations of apostolic preaching is to be abandoned lest it be able to stain others with unbelief."

Irenaeus of Lyons

Against Heresies, Book 3, Chapter 2, Section 2

"But, again, when we refer them to that tradition which originates from the apostles, [and] which is preserved by means of the succession of presbyters in the Churches."

Irenaeus of Lyons

Against Heresies, Book 3, Chapter 3, Section 3

"In this order, and by this succession, the ecclesiastical tradition from the apostles, and the preaching of the truth, have come down to us. And this is most abundant proof that there is one and the same vivifying faith, which has been preserved in the Church from the apostles until now, and handed down in truth."

Salvation by Faith

Protestants and Catholics have made a lot of progress in aligning their views on justification in recent years. Both agree that works are necessary but not causal for salvation. Despite the difference between imputed and infused righteousness, the major difference is not in the salvific role of faith, but rather in the need for penance. Nevertheless, Sola Fide is a cornerstone of the Reformation. Surprisingly, salvation was not one of the primary doctrines fleshed out in the early church. So the church fathers are not always clear and sometimes disagree on the role of faith and works in the Christian life. However, several fathers did make clear statements supporting salvation by faith alone.

Clement of Rome

1 Clement (c. 97 AD)

"And so we, having been called through His will in Christ Jesus, are not justified through ourselves or our own wisdom or understanding or piety, or works that we have done in holiness of heart, but through faith, by which the Almighty God has justified all who have existed from the beginning."

Basil of Caesarea

Homily on Humility, PG 31.532

"Indeed, this is the perfect and complete glorification of God, when one does not exult in his own righteousness, but recognizing oneself as lacking true righteousness to be justified by faith alone in Christ."

Hilary of Poitiers

Commentary on Matthew 21.15

"Because faith alone justifies… publicans and prostitutes will be first in the kingdom of heaven."

John Chrysostom

Homily on Galatians 3

"They said that he who adhered to faith alone was cursed; but he, Paul, shows that he who adhered to faith alone is blessed."

John Chrysostom

Commentary on Luke 23 — the Thief on the Cross (c. 400 AD)

"He made his way into paradise — not having fasted, not having been baptized in water, not having received the Eucharist — on the basis of faith alone."

John Chrysostom

Homilies on Romans, Homily 9 on Romans 5:2

"For he died for us, and further reconciled us, and brought us to Himself, and gave us grace unspeakable. But we brought faith only as our contribution."

Ambrose of Milan

Letter 73 (c. 390 AD)

"Wherefore let no man glory in works, for by his works no man shall be justified, for he that is just hath a free gift, for he is justified by the Bath. It is faith then which delivers by the blood of Christ."

John Chrysostom

Homily 7 on Romans (c. 400 AD)

"Here he shows God's power, in that He has not only saved, but has even justified, and led them to boasting — and this too without needing works, but looking for faith only."

John Chrysostom

Epistle to Titus, Homily 3

"For you believe the faith; why then do you add other things, as if faith were not sufficient to justify? You make yourselves captive, and you subject yourself to the law."

John Chrysostom

Homily on Romans 7 (on Romans 3:25)

"The declaring of his righteousness also means that not only is he himself righteous but that he also makes those who are filled with the putrefying sores of sin instantaneously righteous. And in order to further explain what he means by this 'declaring,' he has added, 'That he might be just, and the justifier of him who believes in Jesus.' Have no doubt, then, for it is not of works but of faith."

John Chrysostom

On Romans 5

"God's grace has allowed Him that did no wrong to be punished for those who had done wrong… Him that was righteousness itself, 'He made sin,' that is, allowed Him to be condemned as a sinner, as one cursed to die, so that we might be, not just 'righteous' but 'righteousness,' indeed the righteousness of God."

Ambrose of Milan

Letter 76 (c. 390 AD)

"To this end has His grace and goodness been formed upon us in Christ Jesus: that being dead according to works, redeemed through faith and saved by grace, we might receive the gift of this great deliverance."

Cyril of Alexandria

Commentary on the Gospel of St. Luke

"By mercy then is signified, Justification and grace in Christ, even that which is by faith. For we have been justified, not by the works of the law that we have done, but by His great mercy."

John Chrysostom

Homilies on Galatians 4

"We need none of those legal observances, he says; faith suffices to obtain for us the Spirit, and by Him righteousness, and many and great benefits."

John Chrysostom

Homily on Philippians 3

"And he well said, 'a righteousness of mine own,' not that which I gained by labor and toil, but that which I found from grace… the righteousness of God; this is altogether a gift. And the gifts of God far exceed those worthless good deeds, which are due to our own diligence."

John Chrysostom

Homily 17 on Romans 10:3

"But he calls it their 'own righteousness,' either because the Law was no longer of force, or because it was one of trouble and toil. But this he calls God's righteousness, that from faith, because it comes entirely from the grace from above, and because men are justified in this case, not by labors, but by the gift of God."

Cyril of Alexandria

Homily 40 on Luke (c. 430 AD)

"For the dwellers upon earth have been justified by faith… Faith then in Christ is found to be the pledge to us of these great blessings: for it is the way that leadeth unto life."

Irenaeus of Lyons

Against Heresies 4.2.7

"Human beings can be saved from the ancient wound of the serpent in no other way than by believing in him who, when he was raised up from the earth on the tree of martyrdom in the likeness of sinful flesh, drew all things to himself and gave life to the dead."

Tertullian

"God will impute righteousness to those who believe in him, and make the just live through him, and declare the Gentiles to be his children through faith."

Gregory of Nazianzus

"Confess Jesus Christ, and believe that He is risen from the dead, and you will be saved. For indeed righteousness is only to be believed; but a complete salvation must also be confessed and knowledge must be added to confidence."

Penal Substitution

Penal Substitutionary Atonement teaches that Christ took on our punishment for sin on the cross, allowing us to be made righteous. This doctrine is largely rejected by the Eastern Orthodox Church, who argue that it is a Reformation-era novelty. In fact, it is expressed in some of the earliest Christian voices.

Epistle to Diognetus

Chapter 9 (c. 2nd century)

"O the sweet exchange, O the incomprehensible work of God, O the unexpected blessings — that the sinfulness of many should be hidden in one righteous person, while the righteousness of one should justify many sinners."

Athanasius of Alexandria

On the Incarnation (c. 318 AD)

"The Word, being Himself incapable of death, assumed a mortal body, that He might offer it as His own in place of all — and suffering for the sake of all through His union with it, might bring to nought him that had the power of death, that is, the devil."

Athanasius of Alexandria

On the Incarnation (c. 318 AD)

"But since it was necessary also that the debt owing from all should be paid again, for… it was owing that all should die… he next offered up his sacrifice also on behalf of all, yielding his temple to death in the stead of all, in order firstly to make men quit and free of their old trespass, and further to show himself more powerful even than death, displaying his own body incorruptible as first fruits of the resurrection of all."

Christ & Church as the Rock

Matthew 16:18 is the foundational text for the Papacy, where Christ says, "You are Peter, and on this rock I will build my church." However, George Salmon notes that only 17 out of 85 patristic references to Matthew 16 refer to Peter as the rock. The rest hold the rock to be his confession of faith, Christ himself, or apply to all believers who make the same confession.

Jerome

Commentary on Matthew

"The rock is Christ, Who gave to His apostles, that they also should be called rocks, 'Thou art Peter, and upon this rock I will build My Church.'"

Augustine of Hippo

Retractions, Book I.21 (c. 426 AD)

"For, 'Thou art Peter' and not 'Thou art the rock' was said to him. But 'the rock was Christ,' in confessing whom, as also the whole Church confesses, Simon was called Peter. But let the reader decide which of these two opinions is the more probable."

Origen of Alexandria

Commentary on Matthew, Book 12, Chapter 11 (c. 248 AD)

"But if you suppose that upon that one Peter only the whole church is built by God, what would you say about John the son of thunder or each one of the Apostles? Shall we otherwise dare to say, that against Peter in particular the gates of Hades shall not prevail, but that they shall prevail against the other Apostles and the perfect?"

Cassiodorus

Exposition of the Psalms

"For the Church cannot be moved because it is known to have been founded on that most solid rock, namely, Christ the Lord..."

Bede

Commentary on Matthew

"You are Peter and on this rock from which you have taken your name, that is, on myself, I will build my Church."

Jerome

Against Jovinian (c. 393 AD)

"The Church is founded upon Peter, although in another place, the same thing is done upon all the Apostles..."

Confession as the Rock

Several Church Fathers interpreted the "rock" of Matthew 16:18 not as Peter's person but as the confession he made — "You are the Christ, the Son of the living God." On this reading, every believer who makes that same confession stands on the same foundation.

Ambrose of Milan

On the Incarnation (c. 380 AD)

"The foundation of the Church: for it was not said of Peter's flesh, but of his faith."

John Chrysostom

Homily on Matthew 16 (c. 400 AD)

"'Thou art Peter, and upon this rock I will build my Church' — that is, on the faith of his confession."

Cyril of Alexandria

Commentary on Isaiah 4.2 (PG 70.940) (c. 430 AD)

"Jesus said to divine Peter: 'You are Peter and upon this rock I will build my Church.' Now by the word 'rock', Jesus indicated, I think, the immoveable faith of the disciple."

Ambrosiaster

Commentary on Ephesians (PL 17.380)

"Wherefore the Lord says to Peter: 'Upon this rock I shall build my Church,' that is, upon this confession of the catholic faith I shall establish the faithful in life."

Hilary of Poitiers

On the Trinity, Book II, Section 23 (c. 356 AD)

"Thus our one immovable foundation, our one blissful rock of faith, is the confession from Peter's mouth, You are the Son of the living God."

Hilary of Poitiers

On the Trinity, Book 6.36–37 (c. 356 AD)

"Hence I ask, was it that the blessed Simon Bar-Jona confessed to Him, 'Thou art the Christ, the Son of the living God?' ... And this is the rock of confession whereon the Church is built ... that Christ must be not only named, but believed, the Son of God. This faith is that which is the foundation of the Church; through this faith the gates of hell cannot prevail against her. This is the faith which has the keys of the kingdom of heaven."

Origen of Alexandria

Commentary on Matthew, Book XII (c. 248 AD)

"If we, too, have said like Peter, 'You are the Christ, the Son of the living God' [Matt. 16:16]...we become a Peter. So, to us there might be said by the Word, 'You are Peter.' For every disciple of Christ is a rock...And upon every such rock is built every word of the church...it is said to Peter, and to every Peter, I will give you the keys to the kingdom of heaven."

Augustine of Hippo

Sermons, Sermon 229P.1 (c. 400 AD)

"Christ, you see, built his Church not on a man but on Peter's confession. What is Peter's confession? 'You are the Christ, the Son of the living God.' There's the rock for you, there's the foundation, there's where the Church has been built, which the gates of the underworld cannot conquer."

Basil of Seleucia

c. 435–468 AD

"Now Christ called this confession a rock, and he named the one who confessed it 'Peter,' perceiving the appellation which was suitable to the author of this confession. For this is the solemn rock of religion, this the basis of salvation, this the wall of faith and the foundation of truth: 'For no other foundation can anyone lay than that which is laid, which is Christ Jesus.' To whom be glory and power forever."

Peter's Symbolic Primacy

Several Fathers acknowledged a real primacy for Peter, but understood it as symbolic rather than jurisdictional. It represents the unity of believers and was designed to prevent schism, not a supreme divine office.

Jerome

Against Jovinian (c. 393 AD)

"But you say the Church was founded 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."

Augustine of Hippo

Tractate 124 on the Gospel of John

"The Church, therefore, which is founded in Christ received from Him the keys of the kingdom of heaven in the person of Peter, that is to say, the power of binding and loosing sins. For what the Church is essentially in Christ, such representatively is Peter in the rock (petra); and in this representation Christ is to be understood as the Rock, Peter as the Church."

Cyprian of Carthage

On the Unity of the Church, 4 (c. 251 AD)

"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."

Rome Can Err

While Rome acknowledges that the Pope can make mistakes, he is meant to infallibly guide the church into truth on faith and morals. The Fathers understood that, regardless of any primacy, Rome could still err, making him subject to excommunication or overruling by a council.

Firmilian of Caesarea

To Cyprian, 256 AD

"But that they who are at Rome do not observe those things in all cases which are handed down from the beginning, and vainly pretend the authority of the apostles."

Firmilian of Caesarea

To Cyprian, 256 AD

"He [Pope Stephen] is really the schismatic who has made himself an apostate from the communion of ecclesiastical unity. For while you think that all may be excommunicated by you, you have excommunicated yourself alone from all."

Augustine of Hippo

Letter 43 (c. 397 AD)

"There still remained a plenary Council of the universal Church, in which these judges themselves might be put on their defense; so that, if they [Rome] were convicted of mistake, their decisions might be reversed."

Third Council of Constantinople (Sixth Ecumenical Council)

681 AD

"And with these we define that there shall be expelled from the holy Church of God and anathematized Honorius, who was Pope of the elder Rome, because we find in his letter to Sergius that he followed his opinion in all things and confirmed his impious doctrines."

Who Holds the Keys to Bind

Rome claims that even if all the apostles had the authority to bind and loose, the keys to the kingdom were given exclusively to Peter. However, the fathers often saw the keys and binding power as interchangeable, both of which were given to the church as a whole.

John Chrysostom

Homily on John 1 (c. 390 AD)

"[John the Apostle] The son of thunder, the beloved of Christ, the pillar of the Churches throughout the world, who holds the keys of heaven."

Augustine of Hippo

Sermon on John 21 (c. 415 AD)

"Did Peter receive the keys and Paul not receive them? Did Peter receive them, and John and James and the other apostles not receive them?... What was given to Peter was given to the whole church."

Tertullian

On Modesty (c. 217 AD)

"If, because the Lord has said to Peter, 'Upon this rock will I build My Church, to you have I given the keys of the heavenly kingdom; or, Whatsoever you shall have bound or loosed in earth, shall be bound or loosed in the heavens,' you therefore presume that the power of binding and loosing has derived to you, that is, to every Church akin to Peter."

Origen of Alexandria

Commentary on Matthew 16 (c. 248 AD)

"Are the keys of the kingdom of heaven given by the Lord to Peter only, and will no other of the blessed receive them? But if this promise be common to the others, how shall not all the things previously spoken of, and the things which are subjoined as having been addressed to Peter, be common to them?...For in this place these words seem to be addressed as to Peter only... but in the Gospel of John the Saviour having given the Holy Spirit unto the disciples by breathing upon them said, 'Receive the Holy Spirit.' Many then will say to the Saviour, 'You are the Christ, the Son of the living God;'...And if any one says this to Him...he will obtain the things that were spoken according to the letter of the Gospel to that Peter, but, as the spirit of the Gospel teaches, to every one who becomes such as that Peter was. For all bear the surname of 'rock' who are the imitators of Christ, that is, of the spiritual rock which followed those who are being saved."

Jerome

Against Jovinian (c. 393 AD)

"But you say the Church was founded 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."

Augustine of Hippo

Sermon (c. 400 AD)

"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."

Power of the Keys

It's often assumed that the keys of the kingdom and the authority to bind and loose entail divine authority to establish doctrine and bind the conscience to dogma that the church decides. However, the fathers often understood it as simply the authority to excommunicate and pronounce divine truths as representatives of Christ.

Augustine of Hippo

Sermon (c. 400 AD)

"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."

Origen of Alexandria

Commentary on Matthew (c. 248 AD)

"Whatever things you shall bind on earth; for with justice has he, who has thrice admonished and not been heard, bound him who is judged to be as a gentile... when one is bound...he remains bound."

Origen of Alexandria

Commentary on Matthew, Book XIII (c. 248 AD)

"But when one judges unrighteously, and does not bind upon earth according to the Word of God, nor loose upon earth according to His will, the gates of Hades prevail against him...But if he [the bishop] is tightly bound with the cords of his sins, to no purpose does he bind and loose."

Jerome

Commentary on Matthew, Book III (c. 398 AD)

"[On binding and loosing] The bishops and priests do not understand this passage. They assume for themselves some of the superciliousness of the Pharisees when they either condemn the innocent or think that they can loose the guilty. Yet in the sight of God it is not the verdict of the priests but the life of the accused that is examined. We read in Leviticus about lepers that they are commanded to show themselves to the priests and, if they have leprosy, then they are established as unclean by the priest. This does not mean that the priests make them leprous and unclean, but that they have knowledge of the leprous and the non-leprous, and they can discern who is clean and who is unclean."

Augustine of Hippo

On Christian Doctrine (c. 397 AD)

"He has given, therefore, the keys to His Church, that whatsoever it should bind on earth might be bound in heaven, and whatsoever it should loose on earth might be loosed in heaven; that is to say, that whosoever in the Church should not believe that his sins are remitted, they should not be remitted to him; but that whosoever should believe and should repent, and turn from his sins, should be saved by the same faith and repentance on the ground of which he is received into the bosom of the Church. For he who does not believe that his sins can be pardoned, falls into despair, and becomes worse as if no greater good remained for him than to be evil, when he has ceased to have faith in the results of his own repentance."

The Development of the Mono-Episcopacy

Rome claims that the bishopric is a unique office above elder and deacon. However, the New Testament uses "bishop" and "elder" interchangeably (Titus 1:5, Phil 1:1, Acts 20:28), and so do the Church Fathers. Early Christians also describe a plurality of elders/bishops leading their congregations, not a Diocesan form of the mono-episcopacy. The system of a single bishop ruling over a city developed in the early second century and was not instituted by Christ.

Jerome

Commentary on Titus 1:5; Letter 146 (c. 397 AD)

"If someone thinks that this is our opinion, but not that of the Scriptures — that bishop and priest are one — the burden of proof lies on them."

Jerome

Letter 146 (c. 397 AD)

"It was decreed for the whole world that one of the priests should be elected to preside over the others, to whom the entire care of the church should pertain, and the seeds of schism would be removed."

The Didache

Chapter 15 (c. 80–120 AD)

"Appoint for yourselves therefore bishops and deacons worthy of the Lord."

1 Clement

42:4–5 (c. 97 AD)

"And thus preaching through countries and cities, they appointed the first-fruits of their labors, having first proved them by the Spirit, to be bishops and deacons of those who should afterwards believe. Nor was this any new thing, since indeed many ages before it was written concerning bishops and deacons. For thus saith the Scripture in a certain place, I will appoint their bishops in righteousness, and their deacons in faith."

Shepherd of Hermas

Similitude 9, 27:2

"Bishops given to hospitality, who always gladly received into their houses the servants of God, without dissimulation. And the bishops never failed to protect, by their service, the widows, and those who were in want, and always maintained a holy conversation."

Shepherd of Hermas

Vision 2, 4:3

"But you will read the words in this city, along with the presbyters who preside over the Church."

Against Papal Supremacy

Neither the Fathers nor the early Ecumenical Councils present Rome as having supreme and universal jurisdiction over all churches. Instead, they present a system of regional leaders with equal honor and authority, where Rome's symbolic primacy was tied to its status as the imperial city.

Council of Carthage — Cyprian presiding

Opening Address, 258 AD (87 bishops present)

"Neither does any of us set himself up as a bishop of bishops, nor by tyrannical terror does any compel his colleague to the necessity of obedience; since every bishop, according to the allowance of his liberty and power, has his own proper right of judgment, and can no more be judged by another than he himself can judge another."

First Council of Constantinople

Canon 2 (381 AD)

"The bishops are not to go beyond their dioceses to churches lying outside of their bounds, nor bring confusion on the churches; but let the Bishop of Alexandria, according to the canons, alone administer the affairs of Egypt; and let the bishops of the East manage the East alone… And let not bishops go beyond their dioceses for ordination or any other ecclesiastical ministrations, unless they be invited."

Council of Chalcedon

Acts of the Council of Chalcedon, Session I (451 AD)

"Constantine the most devout deacon said: 'When the sentence of deposition [of Constantinople] was read, Eutyches appealed to the holy council of the most holy bishops of Rome, Alexandria, Jerusalem, and Thessalonica.'"

Maximinus

Dissertation Against Ambrose (c. 4th century)

"Why do you not understand that the see of Peter is equal and common to all the bishops?"

First Council of Nicaea

Canon 6 (325 AD)

"Let the ancient customs in Egypt, Libya, and Pentapolis prevail, that the Bishop of Alexandria have jurisdiction in all these, since the like is customary for the Bishop of Rome also. Likewise in Antioch and the other provinces, let the Churches retain their privileges."

Council of Chalcedon

Canon 28 (451 AD)

"For the Fathers rightly granted privileges to the throne of old Rome, because it was the royal city. And the One Hundred and Fifty most religious Bishops, actuated by the same consideration, gave equal privileges to the most holy throne of New Rome, justly judging that the city which is honoured with the Sovereignty and the Senate, and enjoys equal privileges with the old imperial Rome, should in ecclesiastical matters also be magnified as she is, and rank next after her."

Gregory the Great

Book IX, Letter 68 (c. 595 AD)

"If one be called universal bishop, the universal Church goes to decay."

John Chrysostom

On John 21 and the Bishop of Antioch (c. 400 AD)

"[bishop of antioch is] another Peter...[who holds] the throne of Peter"

Against Devotional Images

Rome and the East infallibly claim that icon veneration is an apostolic practice (Nicea II). However, the ante-Nicene fathers largely opposed the use of images in worship altogether, and more vehemently opposed veneration as a pagan practice.

Origen of Alexandria

Contra Celsum, VIII.17 (c. 248 AD)

"Nothing should be painted on the walls which is to be adorned by the people… we suffer not to worship at altars, images, or temples."

Origen of Alexandria

Contra Celsum (c. 248 AD)

"It is not possible at the same time to know God and to address prayers to images."

Clement of Alexandria

The Stromata, 7.5 (c. 200 AD)

"Works of art cannot then be sacred and divine."

Lactantius

The Divine Institutes, 2.2 (c. 305 AD)

"There is no religion wherever there is an image… because there can be nothing heavenly in that which is made on earth."

Lactantius

The Divine Institutes, 2.2 (c. 305 AD)

"Why do you not raise your eyes to heaven? Why do you look to walls and wood and stone, rather than to the place where you believe God to be?"

Eusebius of Caesarea

Letter to Constantia, the Emperor's sister (c. 320 AD)

"Can it be that you have forgotten that passage in which God lays down the law that no likeness should be made either of what is in heaven or what is in the earth beneath? Have you ever heard anything of the kind [images] either yourself in church, or from another person? Are not such things banished and excluded from churches all over the world?"

Augustine of Hippo

Sermon on Psalm 115 (c. 400 AD)

"Have they mouth, and yet speak not? Have they eyes, and see not? Do we pray unto them, because through them we pray unto God? This is the chief cause of this insane profanity."

Hippolytus of Rome

Refutation of All Heresies (c. 222 AD)

"and [the Carpocratian heretics'] make counterfit images of Christ"

Origen of Alexandria

Against Celsus 3.76

"And they too are not less insane who think that images, fashioned by men of worthless and sometimes most wicked character, confer any honor upon genuine divinities."

Origen of Alexandria

Against Celsus 7.6

"[Christians] not only avoid temples, altars and images, but are ready to suffer death when it is necessary."

Irenaeus of Lyons

Against Heresies

"[The Carpocratian heretics] also possess images, some of them painted, and others formed from different kinds of material; while they maintain that a likeness of Christ was made by Pilate at that time when Jesus lived among them. They crown these images, and set them up along with the images of the philosophers of the world that is to say, with the images of Pythagoras, and Plato, and Aristotle, and the rest. They have also other modes of honouring these images, after the same manner of the Gentiles."

Augustine of Hippo

Sermon on Psalm

"[reacting negatively] They [pagans] presume to reply, that they worship not the bodies themselves, but the deities which preside over the government of them."

Gregory the Great

Book IX, Letter 105

"It has come to our ears that your Fraternity, seeing certain adorers of images, broke and threw down these same images in Churches. And we commend you indeed for your zeal against anything made with hands being an object of adoration; but we signify to you that you ought not to have broken these images. For pictorial representation is made use of in Churches for this reason; that such as are ignorant of letters may at least read by looking at the walls what they cannot read in books. Your Fraternity therefore should have both preserved the images and prohibited the people from adoration of them."

Against Immaculate Conception

The Immaculate Conception teaches that Mary was born without original sin and never committed a sin in her life. However, the sinlessness of Mary was not a widespread patristic teaching. Several fathers attributed moral failure, doubt, or a fallen nature to Mary.

Clement of Alexandria

The Instructor, Book 1, Chapter 2

"He alone is judge, because He alone is sinless. As far, however, as we can, let us try to sin as little as possible."

Clement of Alexandria

The Instructor, Book 3, Chapter 12

"For this Word of whom we speak alone is sinless. For to sin is natural and common to all."

Tertullian

On the Soul, Chapter 41

"For God alone is without sin; and the only man without sin is Christ, since Christ is also God. . . . Just as no soul is without sin, so neither is any soul without seeds of good."

Tertullian

The Prescription Against Heretics, Chapter 3

"For to the Son of God alone was it reserved to persevere to the last without sin."

Origen of Alexandria

Homilies on Luke, Homily 17.6–7

"What ought we to think? That while the apostles were scandalized, the Mother of the Lord was immune from scandal? If she had experienced scandal during the Lord's Passion, Jesus did not die for her sins. But if all have sinned and fall short of the glory of God, but are justified by his grace and redeemed, then Mary too was scandalized by this moment. This is what Simeon is prophesying about. . . . Your soul will be pierced by the sword of unbelief and will be wounded by the sword point of doubt."

John Chrysostom

Homilies on Matthew, Homily 44.3

"For in fact that which she had essayed to do, was of superfluous vanity; in that she wanted to show the people that she has power and authority over her Son, imagining not as yet anything great concerning Him; whence also her unseasonable approach."

Basil of Caesarea

Letters 260.9

"Simeon therefore prophesies about Mary herself, that when standing by the cross, and beholding what is being done, and hearing the voices, after the witness of Gabriel, after her secret knowledge of the divine conception, after the great exhibition of miracles, she shall feel about her soul a mighty tempest. The Lord was bound to taste of death for every man – to become a propitiation for the world and to justify all men by His own blood. Even thou thyself, who hast been taught from on high the things concerning the Lord, shalt be reached by some doubt. This is the sword. 'That the thoughts of many hearts may be revealed.' He indicates that after the offence at the Cross of Christ a certain swift healing shall come from the Lord to the disciples and to Mary herself."

Augustine of Hippo

Enarrationes in Psalmos 34 (2), 3 (PL 36:335)

"Mary, descended from Adam, died because of sin."

Hilary of Poitiers

Tractatus in Ps. 118

"If this virgin, made capable of conceiving God, will encounter the severity of this judgment, who will dare to escape?"

Against Mary's Assumption

The bodily assumption of Mary was infallibly dogmatized by Rome in 1950 and claimed to be an apostolic belief. However, this doctrine was so unknown for the first four hundred years of the church that it's almost difficult to find relevant quotes to this debate. The first suggestions of Mary's Assumption originated in Gnostic writings. The Church Fathers often expressed uncertainty about what happened to Mary at the end of her life, and their lists of those who've been assumed into heaven only ever included Enoch and Elijah.

Epiphanius of Salamis

Panarion 78

"Either the holy Virgin died and was buried, then her falling asleep was with honor, her death chaste, her crown that of virginity. Or she was killed, as it is written: 'and your own soul a sword shall pierce,' then her glory is among the martyrs and her holy body amid blessings, she through whom light rose over the world. Or she remained alive, since nothing is impossible with God and He can do whatever He desires, for her end no one knows."

Augustine of Hippo

Reply to Faustus the Manichaean 26:1

"Besides that, it is not only Elias, but Moses and Enoch you believe to be immortal, and to have been taken up with their bodies to heaven."

Jerome

To Pammachius Against John of Jerusalem, 29

"Enoch was translated in the flesh; Elias was carried up to heaven in the flesh. They are not dead, they are inhabitants of Paradise."

Tertullian

On the Resurrection of the Flesh 58

"That Enoch and Elias, who even now, without experiencing a resurrection (because they have not even encountered death), are learning to the full what it is for the flesh to be exempted from all humiliation, and all loss, and all injury, and all disgrace — translated as they have been from this world."

Irenaeus of Lyons

Against Heresies 5:5

"For Enoch, when he pleased God, was translated in the same body in which he did please Him, thus pointing out by anticipation the translation of the just. Elijah, too, was caught up [when he was yet] in the substance of the [natural] form; thus exhibiting in prophecy the assumption of those who are spiritual, and that nothing stood in the way of their body being translated and caught up."

Constitutions of the Holy Apostles

5.1.7

"Now that, if it had pleased Him that all men should be immortal, it was in His power, He showed in the examples of Enoch and Elijah, while He did not suffer them to have any experience of death."

Tertullian

A Treatise on the Soul 50

"Enoch no doubt was translated, and so was Elijah; nor did they experience death: it was postponed, (and only postponed,) most certainly."

John Chrysostom

Homilies on John, 75

"And Enoch also, having worn flesh, was translated, and not found. So also Elias was caught up with the flesh."

Origen of Alexandria

Commentary on the Epistle to the Romans 5:4:3

"Enoch and Elijah, who were translated so as to not see death."

Cyril of Jerusalem

Catechetical Lectures 14:25

"Remember that Enoch was translated; but Jesus ascended: remember what was said yesterday concerning Elias, that Elias was taken up in a chariot of fire; but that the chariots of Christ are ten thousand-fold even thousands upon thousands: and that Elias was taken up, towards the east of Jordan; but that Christ ascended at the east of the brook Cedron: and that Elias went as into heaven; but Jesus, into heaven."

Cyril of Jerusalem

Catechetical Lectures 3:6, 14:25

"You may mention Elias the Tishbite who was taken up into heaven, yet he is not greater than John: Enoch was translated, but he is not greater than John."

Augustine of Hippo

On the Grace of Christ, and on Original Sin 2:27

"As when it is asked where Elijah is at the present moment, and where Enoch — whether in this Paradise or in some other place, although we doubt not of their existing still in the same bodies in which they were born."

Ambrose of Milan

On the Death of Satyrus 2:94

"When he wrote that he should be caught up alive in the clouds to meet Christ? We read the same too of Enoch and of Elijah."

Methodius of Olympus

From the Discourse on the Resurrection 3:2:14

"And if any one should speak doubtfully concerning the soul of Elias, as that the Scriptures say that he was taken up in the flesh..., as was also proved by the translation of Enoch."

Penance

Rome teaches that one must confess mortal sin to a priest, or you lose your salvation. These mortal sins can be as common as missing Mass on Sunday. Frequent confession is expected to remain in a state of grace. However, this is not consistent with the Patristic practice of confession. Early Christians would confess openly to the congregation for their own spiritual well-being. For offenses that harmed the entire church, such as murder and adultery, these sins led to excommunication. In the third century, it was standard practice for bishops to offer only one penance (or a one-time re-admittance to the Church) for an entire lifetime.

Tertullian

On Repentance, Chapter 9

"the sphere of action of this second and only (remaining) repentance."

Origen

"For the graver crimes, there is only one opportunity of penance."

Shepherd of Hermas

Book 2, Chapter 3

"If anyone is tempted by the devil, and sins after that great and holy calling [baptism]... he has opportunity to repent but once."

Ambrose of Milan

"As there is one baptism, so there is one penance, which, however, is performed publicly."

John Chrysostom

"I do not say that you should make your sins known in public, nor that you should accuse yourself before others, but I would have you obey the prophet who says, 'Make known your ways before God'. Therefore, confess your sins before God, the true Judge, with prayer. Tell your errors, not with the tongue, but with the memory of your conscience, and so forth."
