Dates: c. 321 AD (Alexander of Alexandria, also Alexander I; bishop — Pope and Patriarch — of Alexandria from 313 until his death on 17 April 326/328; the prelate who first condemned Arius and presided over the Alexandrian synod that deposed him (c. 318–321), and whose deacon and chosen successor was Athanasius. The encyclical letter to Alexander of Byzantium in which the citations below occur is dated c. 319–324; distinct from Clement and Athanasius of Alexandria) · Wikipedia
Summary: The bishop who opened the Arian controversy weaves the deuterocanonical Sirach (Ecclesiasticus) into the very texture of his christological argument. Pressing the inscrutability of the eternal generation of the Word, he chains together — in a single breath, governed by the warning “not listening to this saying” and the cap “that passage” — Sirach 3:21, the Apostle Paul (1 Corinthians 2:9), Genesis 15:5, Sirach 1:2, and Isaiah 53:8. He does not introduce the Sirach lines with the bare formula “Scripture says” (as Methodius does for Wisdom); he uses them — as authority for the limits of inquiry and as one of a string of scriptural testimonies — on the same footing as Paul, Moses, and the prophet. He compiles no canon-list, so he renders no canon-verdict; the witness is to early-fourth-century Alexandrian practice, a softer datapoint than an explicit Scripture-formula but a real one, set between Eusebius and the Council of Nicaea.
In his great encyclical against Arius — the letter to Alexander, bishop of Byzantium (Constantinople) — Alexander argues that the manner of the Son’s eternal generation lies beyond human inquiry. To fence off the speculation, he marshals a chain of texts:
Wherefore I do not think that he is to be reckoned among the pious who presumes to inquire into anything beyond these things, not listening to this saying: Seek not out the things that are too hard for you, neither search the things that are above your strength. For if the knowledge of many other things that are incomparably inferior to this, are hidden from human comprehension, such as in the apostle Paul, Eye has not seen, nor ear heard, neither have entered into the heart of man, the things which God has prepared for them that love Him. As also God said to Abraham, that he could not number the stars; and that passage, Who can number the sand of the sea, and the drops of rain… How shall any one be able to investigate too curiously the subsistence of the divine Word, unless he be smitten with frenzy? Concerning which the Spirit of prophecy says, Who shall declare his generation?

The Sirach lines are not labelled or distinguished from the canonical texts they stand among; they do the same evidentiary work in the same argument.
Alexander of Alexandria, Epistles on the Arian Heresy and the Deposition of Arius, Epistle I, §5 (Roberts–Donaldson translation, Ante-Nicene Fathers vol. 6): “…not listening to this saying: Seek not out the things that are too hard for you, neither search the things that are above your strength… and that passage, Who can number the sand of the sea, and the drops of rain…” The first quotation is Sirach (Ecclesiasticus) 3:21; the second is Sirach 1:2. They are chained with 1 Corinthians 2:9, Genesis 15:5, and Isaiah 53:8. ↩
