Muratorian Canon: For the blessed apostle Paul himself, following the rule of his predecessor John, writes only by name to seven Churches in the following order–to the Corinthians a first…there is a second to the Corinthians and to the Thessalonians, yet one Church is recognized as being spread over the entire world…Howbeit to Philemon one, to Titus one, and to Timothy two were put in writing…to be in honor however with the Catholic Church for the ordering of ecclesiastical discipline…one to the Laodicenes, another to the Alexandrians, both forged in Paul’s name to suit the heresy of Marcion, and several others, which cannot be received into the Catholic Church; for it is not fitting that gall be mixed with honey. The Epistle of Jude no doubt, and the couple bearing the name of John, are accepted by the Catholic Church…But of Arsinous, called also Valentinus, or of Militiades we receive nothing at all (inter A.D. 180-200).
St. Hippolytus: What is narrated here [in the story of Susannah] happened at a later time, although it is placed at the front of the book [of Daniel], for it was a custom with the writers to narrate many things in an inverted order in their writings. . . . [W]e ought to give heed, beloved, fearing lest anyone be overtaken in any transgression and risk the loss of his soul, knowing as we do that God is the judge of all and the Word himself is the eye which nothing that is done in the world escapes. Therefore, always watchful in heart and pure in life, let us imitate Susannah (Commentary on Daniel[A.D. 204]).
Tertullian: 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–I mean the Gospels of John and Matthew–whilst that which Mark published may be affirmed to be Peter’s whose interpreter Mark was. For even Luke’s form of the Gospel men usually ascribe to Paul (Against Marcion 4:5 [inter A.D. 207-212]).
Origen: In his [Origen] first book on Matthew’s Gospel, maintaining the Canon of the Church, he testifies that he knows only four Gospels, writing as follows: Among the four Gospels, which are the only indisputable ones in the Church of God under heaven, I have learned by tradition that the first was written by Matthew, who was once a publican, but afterwards an apostle of Jesus Christ, and it was prepared for the converts from Judaism, and published in the Hebrew language. The second is by Mark, who composed it according to the instructions of Peter, who in his Catholic epistle acknowledges him as a son, saying, ‘The church that is at Babylon elected together with you, saluteth you, and so doth Marcus, my son.’ And the third by Luke, the Gospel commended by Paul, and composed for Gentile converts. Last of all that by John (Commentary on Matthew, fragment in Eusebius Church History 6:25:3 [A.D. 244]).
St. Cyril of Jerusalem: Learn also diligently, and from the Church, what are the books of the Old Testament, and what those of the New. And, 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? (Catechetical Lectures4:33 [A.D. 350]).
The Council of Hippo: Besides the canonical Scriptures, nothing shall be read, in the church under the title of divine writings. The canonical books are:—Genesis, Exodus, Leviticus, Numbers, Deuteronomy, Joshua, Judges, Ruth, the four books of Kings, the two books of Paraleipomena (Chronicles), Job, the Psalms of David, the five books of Solomon, the twelve books of the (Minor) Prophets, Isaiah, Jeremiah, Daniel, Ezekiel, Tobias, Judith, Esther, two books of Esdras, two books of the Maccabees. The books of the New Testament are:—the four Gospels, the Acts of the Apostles, thirteen Epistles of S. Paul, one Epistle of S. Paul to the Hebrews, two Epistles of S. Peter, three Epistles of S. John, the Epistle of S. James, the Epistle of S. Jude, the Revelation of S. John. Concerning the confirmation of this canon, the transmarine Church shall be consulted (Canon 36 [A.D. 393]).
St. Athanasius: I beseech you to bear patiently, if I also write, by way of remembrance, of matters with which you are acquainted, influenced by the need and advantage of the Church. In proceeding to make mention of these things [the canon], I shall adopt, to comment my undertaking, the pattern of Luke…to reduce into order for themselves the books termed apocryphal, and to mix them up with the divinely inspired Scripture, concerning which we have been fully persuaded, as they who from the beginning were eyewitnesses and ministers of the Word, delivered to the fathers; it seemed good to me also, having been urged thereto by true brethren, and having learned from the beginning, to set before you the books included in the Canon (Festal Letters 39 [A.D. 397]).
The Council of Carthage: [It has been decided] that nothing except the Canonical Scriptures should be read in the church under the name of the Divine Scriptures. But the Canonical Scriptures are: Genesis, Exodus, Leviticus, Numbers, Deuteronomy, Josue, Judges, Ruth, four books of Kings, Paralipomenon two books, Job, the Psalter of David, five books of Solomon, twelve books of the Prophets, Isaias, Jeremias, Daniel, Ezekiel, Tobias, Judith, Esther, two books of Esdras, two books of the Maccabees. Moreover, of the New Testament: Four books of the Gospels, the Acts of the Apostles one book, thirteen epistles of Paul the Apostle, one of the same to the Hebrews, two of Peter, three of John, one of James, one of Jude, the Apocalypse of John (Canon 47 [A.D. 397]).
St. Augustine: The authority of our books [Scriptures], which is confirmed by agreement of so many nations, supported by a succession of apostles, bishops, and councils, is against you (Reply to Faustus the Manichean 13:5 [A.D. 400]).
The Council of Toledo: If anyone shall say, or shall believe, that other Scriptures, besides those which the Catholic Church has received, are to be esteemed of authority, or to be venerated, let him be anathema (Canon 12 [A.D. 400]).
Pope Innocent of Rome: A brief addition shows what books really are received in the canon. These are the desiderata of which you wished to be informed verbally: of Moses five books, that is, of Genesis, of Exodus, of Leviticus, of Numbers, of Deuteronomy, and Josue, of Judges one book, of Kings four books, also Ruth, of the Prophets sixteen books, of Solomon five books, the Psalms. Likewise of the histories, Job one book, of Tobias one book, Esther one, Judith one, of the Maccabees two, of Esdras two, Paralipomenon two books. Likewise of the New Testament: of the Gospels four books, of Paul the Apostle fourteen epistles, of John three, epistles of Peter two, an epistle of Jude, an epistle of James, the Acts of the Apostles, the Apocalypse of John (Letter to Exsuperius Bishop of Toulose 6:7:13 [A.D. 405]).
The Early Church Father’s quotation of the ‘Deuterocanonical’ Books:
St. Clement of Rome: By the word of his might [God] established all things, and by his word he can overthrow them. “Who shall say to him, ‘What have you done?’ or who shall resist the power of his strength?” [Wisdom 12:12] (Letter to the Corinthians 27:5 [A.D. 95]).
Tertullian: For they remembered also the words of Jeremias writing to those over whom that captivity was impending: “And now you shall see borne upon (men’s) shoulders the gods of the Babylonians, of gold and silver and wood, causing fear to the Gentiles. Beware, therefore, that you also do not be altogether like the foreigners and be seized with fear while you behold crowds worshipping those gods before and behind, but say in your mind, our duty is to worship You, O Lord” [Baruch 6:3-5] (Scorpians Antidote 8 [A.D. 211]).
St. Hippolytus: But they make use also of other testimonies, and say, thus it is written: “This is our God, and there shall none other be accounted of in comparison of Him. He hath found out all the way of knowledge, and hath given it unto Jacob His servant (son), and to Israel His beloved. Afterward did He show Himself upon earth and conversed with men.” [Baruch 3:36-38] (Against Noetus 2 [A.D. 205]).
St. Irenaeus of Lyon: And Jeremiah the prophet has pointed out, that as many believers as God has prepared for this purpose, to multiply those left upon earth, should both be under the rule of the saints to minister to this Jerusalem, and that [His] kingdom shall be in it, saying: [quotes Baruch 4:26 et seq.] “Look around Jerusalem towards the east, and behold the joy which comes to you from God Himself… For God shall go before with joy in the light of His splendor, with the pity and righteousness which proceeds from Him” [Baruch 4:36-5:9] (Against Heresies 5:35:1 [A.D. 189]).
St. Clement of Alexandria: ‘A fool raises his voice in laughter,” says the Scripture; “but a clever man smiles almost imperceptibly” (Sirach 21:20). The clever man in this case he calls wise, inasmuch as he is differently affected from the fool. But, on the other hand, one needs not be gloomy, only grave. For I certainly prefer a man to smile who has a stern countenance than the reverse; for so his laughter will be less apt to become the object of ridicule (The Instructor of Children 2:5 [A.D. 191]).
Those, then, will not escape the curse of yoking an ass with an ox, who, judging certain things not to suit them, command others to do them, or the reverse. This Scripture has briefly showed, when it says, “What you hate you shall not do to another” [Tobit 4:15] (Stromata2:23 [A.D. 202]).
Origen: But that we may believe on the authority of holy Scripture that such is the case, hear how in the book of Maccabees, where the mother of seven martyrs exhorts her son to endure torture, this truth is confirmed; for she says, “I ask of thee, my son, to look at the heaven and the earth, and at all things which are in them, and beholding these, to know that God made all these things when they did not exist” [2 Maccabees 7:28] (On First Principles 2:1:5 [A.D. 225]).
St. Cyprian of Carthage: And again, where the sacred Scripture speaks of the tortures which consecrate God’s martyrs, and sanctify them in the very trial of suffering: “And if they have suffered torments in the sight of men, yet is their hope full of immortality; and having been a little chastised, they shall be greatly rewarded: for God proved them, and found them worthy of Himself. As gold in the furnace has He tried them, and received them as a sacrifice of a burnt-offering, and in due time regard shall be had unto them. The righteous shall shine, and shall run to and fro like sparks among the stubble. They shall judge the nations, and have dominion over the people; and their Lord shall reign forever” [Wisdom 3:4-8] (Letter 80:2 [A.D. 250]).
Holy Scripture meets and warns us, saying: “And fear not the words of a sinful man, for his glory shall be dung and worms. Today he is lifted up, and tomorrow he shall not be found, because he is turned into his earth, and his thought shall perish” [1 Maccabees 2:62-63] (Letter 54:3 [A.D 251-253]).
St. Methodius of Olympus: And that you may not take refuge behind a safe wall, bringing forward the Scripture which says, “As for the children of the adulterers, they shall not come to their perfection” (Wisdom 3:16). He will answer you easily, that we often see those who are unlawfully begotten coming to perfection like ripe fruit (The Banquet of the Ten Virgins 2:3 [circa A.D. 311]).
St. Athanasius: But of these and such like inventions of idolatrous madness, Scripture taught us beforehand long ago, when it said: “The devising of idols was the beginning of fornication, and the invention of them, the corruption of life… for men serving either calamity or tyranny, did ascribe unto stones and stocks the incommunicable Name” [Wisdom 14:13] (Against the Heathen 1:11:1 [A.D 326]).
St. Hilary of Poitiers: For all things, as the Prophet says, were made out of nothing [2 Maccabees 7:28] it was no transformation of existing things, but the creation into a perfect form of the non-existent (On the Trinity 4:16 [A.D. 356-360]).
As you have listened already to Moses and Isaiah, so listen now to Jeremiah inculcating the same truth as they: “This is our God, and there shall be none other likened unto Him, Who has found out all the way of knowledge, and has given it unto Jacob His servant and to Israel His beloved. Afterward did He show Himself upon earth and dwelt among men” [Baruch 3:36-38] (ibid 4:42).
St. Ambrose of Milan: Justly, then, is he wise who has received of the Lord to know when he ought to speak. Wherefore the Scripture says well: ”A wise man will keep silence until there is opportunity” [Sirach 20:76] (On the Duties of the Clergy 1:2:5 [A.D. 391]).
We have spoken of its beauty, and proved it by the witness of Scripture. It remains to show on the authority of Scripture that there can be no fellowship between it and vice, but that it has an inseparable union with the rest of the virtues. “It has a spirit sagacious, undefiled, sure, holy, loving what is good, quick, that never forbids a kindness, kind, steadfast, free from care, having all power, overseeing all things.” And again: “She teacheth temperance and justice and virtue” [Wisdom 7:22-24] (ibid 2:13:65).
St. John Cassian: Wherefore, as Scripture says, “when you go forth to serve the Lord stand in the fear of the Lord, and prepare your mind” [Sirach 2:1] (The Institutes 4:37 [A.D. 425-430]).
