And how long shall we draw the saw to and fro through this line, when we have an ancient practice, which by anticipation has made for us the state, i.e., of the question? If no passage of Scripture has prescribed it, assuredly custom, which without doubt flowed from tradition, has confirmed it. For how can anything come into use, if it has not first been handed down?
Tertullian
The Chaplet
Chapter III
Now in ancient times the people we call Jews bare the name of Hebrews, and so both their writings and their speech were Hebrew. But that the understanding of their books might not be wanting, this also the Jews supplied to Ptolemy; for they gave him seventy-two interpreters—men whom the philosopher Menedemus, the well-known asserter of a Providence, regarded with respect as sharing in his views.
Tertullian
Apology
Chapter XVIII
Now Clement, writing in the sixth book of the Hypotyposes, makes this statement. For he says that Peter and James and John, after the Savior’s ascension, though pre-eminently honored by the Lord, did not contend for glory, but made James the Just, bishop of Jerusalem.
Eusebius of Caesarea
Church History
Chapter VI.II
Quotation from lost work of Clement of Alexandria
Yes, truly, the apostles were baptized, as Clement the Stromatist relates in the fifth book of the Hypotyposes. For, in explaining the apostolic statement, I thank God that I baptised none of you, he says, Christ is said to have baptised Peter alone, and Peter Andrew, and Andrew John, and they James and the rest.
St. John Moschus
Spiritual Meadow, Book V
Chapter 176
Quote from lost work of Clement of Alexandria
“Marcus, my son, saluteth you.” Mark, the follower of Peter, while Peter publicly preached the Gospel at Rome before some of Cæsar’s equites, and adduced many testimonies to Christ, in order that thereby they might be able to commit to memory what was spoken, of what was spoken by Peter, wrote entirely what is called the Gospel according to Mark. As Luke also may be recognised by the style, both to have composed the Acts of the Apostles, and to have translated Paul’s Epistle to the Hebrews.
Jude, who wrote the Catholic Epistle, the brother of the sons of Joseph, and very religious, whilst knowing the near relationship of the Lord, yet did not say that he himself was His brother.
Clement of Alexandria
The Stromata, Book VIII
Chapter VIII
Therefore in substance and idea, in origin, in pre-eminence, we say that the ancient and Catholic Church is alone, collecting as it does into the unity of the one faith— which results from the peculiar Testaments, or rather the one Testament in different times by the will of the one God, through one Lord— those already ordained, whom God predestinated, knowing before the foundation of the world that they would be righteous. But the pre-eminence of the Church, as the principle of union, is, in its oneness, in this surpassing all things else, and having nothing like or equal to itself. But of this afterwards. Of the heresies, some receive their appellation from a [person’s] name, as that which is called after Valentinus, and that after Marcion, and that after Basilides, although they boast of adducing the opinion of Matthew [without truth]; for as the teaching, so also the tradition of the apostles was one. Some take their designation from a place, as the Peratici; some from a nation, as the [heresy] of the Phrygians; some from an action, as that of the Encratites; and some from peculiar dogmas, as that of the Docetæ;, and that of the Hærmatites; and some from suppositions, and from individuals they have honoured, as those called Cainists, and the Ophians; and some from nefarious practices and enormities, as those of the Simonians called Entychites.

Our Gnostic then alone, having grown old in the Scriptures, and maintaining apostolic and ecclesiastic orthodoxy in doctrines, lives most correctly in accordance with the Gospel, and discovers the proofs, for which he may have made search (sent forth as he is by the Lord), from the law and the prophets. For the life of the Gnostic, in my view, is nothing but deeds and words corresponding to the tradition of the Lord.
Clement of Alexandria
The Stromata, Book VI
Chapter XVI
And as those almonds are called empty in which the contents are worthless, not those in which there is nothing; so also we call those heretics empty, who are destitute of the counsels of God and the traditions of Christ; bitter, in truth, like the wild almond, their dogmas originating with themselves, with the exception of such truths as they could not, by reason of their evidence, discard and conceal.
Clement of Alexandria
The Stromata, Book VII
Chapter XVI
But, as appears, many even down to our own time regard Mary, on account of the birth of her child, as having been in the puerperal state, although she was not. For some say that, after she brought forth, she was found, when examined, to be a virgin.
Now such to us are the Scriptures of the Lord, which gave birth to the truth and continue virgin, in the concealment of the mysteries of the truth. “And she brought forth, and yet brought not forth,” says the Scripture; as having conceived of herself, and not from conjunction. Wherefore the Scriptures have conceived to Gnostics; but the heresies, not having learned them, dismissed them as not having conceived.
Clement of Alexandria
The Stromata, Book VII
Chapter XVI
They say in the traditions that Matthew the apostle constantly said, that “if the neighbor of an elect man sin, the elect man has sinned. For had he conducted himself as the Word prescribes, his neighbor also would have been filled with such reverence for the life he led as not to sin.”
