Constantine’s Idealized World Order: Universality through Unity

Constantine was obsessed with unity. We know this because of the archive attesting to his guidance in adjudicating the Nicene controversy, comprising letters from the emperor to his subordinates trying to diffuse an increasingly tense battle of minds and wills.Footnote ¹ But Constantine’s concern with unity was epistemic rather than preceptual. The first Christian emperor was ultimately unconcerned with the subject upon which his subordinates agreed, as I argue later in this chapter. Rather, he was interested chiefly in the fact of their agreement, and with the relationship between intellectual unity and the bestowal of divine favor on the empire.Footnote ²

In the early years of the Nicene controversy Constantine wrote a letter to its two central disputants: an Alexandrian presbyter named Arius and Alexander, the metropolitan bishop of Alexandria:

As will become clear, Constantine took his role as mediator seriously. In this letter, dated to 324Footnote ⁵ (and thus immediately before the Council of Nicaea was convened), the emperor stakes out his initial position on the question that Arius and Alexander disputed, and which they had formed intellectual alliances to defend.Footnote ⁶ To Constantine, the question was inane – asked out of foolishness and answered in haste. “Now forgive one another for both the careless question and the ill-considered answer,” orders Constantine, and let the clergy behave as a philosophical school.

The emperor made clear that there was no discernible difference between Arius and Alexander regarding matters of cultic import and thus ordered them to reestablish communion.Footnote ⁸ Constantine held that as long as divergent theological viewpoints were justifiable under the umbrella of Orthodoxy they were to be tolerated by the clerical elite. This is a position from which Constantine did not sway, even as he ordered the banishment of Arius and two members of his party less than a year later. The question, then as ever, was how wide the umbrella of orthodoxy cast its shadow, and whether it should be assumed to cover mostly matters of practice or primarily matters of belief.

At first glance, the emperor’s fragmentary letter to the church at Nicomedia after the Council of Nicaea sounds like an abrupt departure from the conciliatory tone taken in the previous letter to Arius and Alexander:

This letter appears to present a stark divergence from the letter of Constantine of the previous letter, where he urged the disputing factions to set aside their differences for the good of the community because their differences were neither cultically actionable nor, to his mind, particularly interesting. The question of the precise relationship of the Son to the Father, adjudicated in excruciating detail at the council under Constantine’s own aegis, was “a careless question” that elicited “an ill-considered answer.”

How can it be that Constantine appears to have changed his mind so drastically on the substance of the question while remaining convinced that his actions aimed only at unity in the church? On a cursory reading it might seem that Constantine’s rhetoric is expedient and duplicitous: he has sided with the “winners” of the council. But this answer is too easy, and it fails to account for the fact of the Council of Nicaea itself. Before the Council of Arles in 314 that was similarly called by Constantine, there was no precedent for imperially sanctioned meetings whose aim is to hammer out theological points and arrive at a state of unity.Footnote ¹⁰ There is no reason to think that the pronouncements of ecclesiastical councils would have come to represent the primary node of authority within later Christian theological disputation without Constantine’s own initiative.Footnote ¹¹ Rather, it was Constantine’s lifelong obsession with unity that led to his calling for councils in the first place.Footnote ¹² We cannot then say that his seeming “change of position” relies on the authority of the Council of Nicaea – the authority of the council is a direct result of Constantine’s sanction, a patronage borne of his singular concern for unity regardless of the particular, preceptual content of that singular faith.

By his own admission the emperor’s obsession with ecclesial unity overlies a traditional Roman concern for the “peace of the gods (pax deorum)”; human beings please the gods under the direction of the emperor, and the gods bestow gifts upon the empire in return. When Constantine called for unity among the Catholic community he did not invoke some internal theological need as justification. Rather, he warned that dissension may lead the Christian god to withhold favor from his reign.Footnote ¹³ His letter to Alexander and Arius quoted earlier, composed on the eve of the Council of Nicaea, begins as follows:

Here Constantine claims two interrelated purposes: the unity of doctrine and the prosperity of the empire. These are not separate issues, he clarifies, but two sides of the same coin: only doctrinal unity guarantees divine favor – the divine favor that undergirded his own claim to imperial authority, as it had for his Tetrarchic predecessors.Footnote ¹⁵ He expressed the same purpose in a general letter to Catholic communities written just a few days after the Council of Nicaea’s close:

A traditional interpretation of this letter would agree with James Stevenson, that Constantine simply misunderstood the significance of the dispute.Footnote ¹⁷ Seen in the context of Constantine’s broader interest in unity and the material consequences of dissent, and taking the emperor’s own assertion of intent at face value, we can say that the traditional interpretation is woefully inadequate. Rather, in this letter Constantine shows that his concern for doctrinal unity was simply not preceptual: he didn’t much care what it was that the theologians agreed upon, at least in principle – unity is necessary in the first instance because it is unity that guarantees the general prosperity of the empire.Footnote ¹⁸ Later in this letter he demonstrates the mechanics of this Christian epistemic commitment in the same way that Valerius Maximus’s story at the beginning of Chapter 2 displays the mechanics of Traditionalist Roman epistemology. In Constantine’s eyes, it is inappropriate a priori for one group to be fasting while another feasts. “As I am sure you all are already aware, it is for this reason divine Providence desires that this matter should achieve the proper settlement and be brought under a single regulation.”Footnote ¹⁹

Constantine’s concern for proper cultic performance as guarantor of divine protection is not unique to him, nor is it peculiarly Christian. Susanna Elm showed in Sons of Hellenism that the pax deorum, and by extension the pax Romana, was always bound up in the discovery of universal philosophical precepts. “[I]ntegration, especially of things divine, was dangerous, since false teachings of false gods – wrong innovations – threatened the security and longevity of the oikoumenē. Greek and Roman history provided sufficient examples of the divine wrath called forth by such mistakes. Who, then, was innovating correctly?”Footnote ²⁰ Imperial stability was always an epistemic concern. Cicero makes precisely the same connection in his Laws.Footnote ²¹ The logic was not unique to Constantine even among early fourth-century Catholics. In his oration to honor the emperor’s thirty years in the purple, Eusebius of Caesarea echoed back to Constantine the connection between doctrinal unity and imperial prosperity, which began already with Augustus:

Roman Traditionalists of the later fourth century did not desert the classical understanding of the pax deorum, either. Symmachus, one of the last truly influential Traditionalists in the Roman aristocracy, famously scolded the boy emperor Valentinian II in 384. “Who is so friendly with the barbarians that he doesn’t need an Altar of Victoria? … Those who it doesn’t benefit – let them disdain this power. Don’t you go and abandon a patronage that favors your triumphs (Vos amicum triumphis patrocinium nolite deserere)!”Footnote ²³

Constantine’s concern with intellectual unity was a traditional Roman anxiety over the pax deorum refracted through Christian theological commitments.Footnote ²⁴ The emperor’s focus on universality, predicated on the empire’s need of divine favor, defined his approach to truth. His desire to identify and promulgate a statement of universal truth, in turn, determined the shape and focus of the Catholic Christianity that flourished in his wake. This is not to say that before the reign of Constantine, Christian scholars were not interested in doctrinal unity. Rather, before the blending of Christian theology with imperial ideology that occurred under the patronage of Constantine, the impetus toward unity among Christians was never chiefly the general prosperity of the Roman empire. Constantine was a Christian, but he was a Roman Christian, and he brought Roman ideologies of religion and state to bear on his adjudication of the Nicene Controversy. It was the first time that Christian theology was being done with an army at its back. The fact that Nicene Christians insisted so assiduously and violently on doctrinal uniformity cannot be separated from a Roman ideology of state laid over theological disputation during the reign of the empire’s first Christian sovereign.

The preceding has been an analysis of the scholarly method of early Christians who were actively forging new ideas about scripture and scriptural interpretation. A young Athanasius was present at the Council of Nicaea, intending to apply his keen exegetical skills to scripture: excising biblical language to construct a new statement of faith that could unite factions and bring the unity – and thereby the prosperity – that Constantine so desperately desired. By the end of his life Athanasius had shifted away from his youthful contention that scripture and scriptural interpretation was chiefly important for clarifying doctrine, and so had his Catholic peers.

Athanasius of Alexandria

Athanasius always punched above his weight. He was enduringly controversial during his life, earning both five imperial exiles and an oration of praise by the bishop of Constantinople, who called him “the pillar of the Church” some eight years after his death.Footnote ²⁵ He spent a long life in service of the Nicene definition of faith, which was conceived just three years before he succeeded his patron and mentor Alexander as bishop of Alexandria. Over the course of Athanasius’s public life, which spanned almost precisely the period between the Council of Nicaea and the beginning of the Theodosian dynasty, Orthodox disputants on either side of the Nicene controversy shifted their defensive tactics.Footnote ²⁶ Along with his interlocutors and contemporaries, Athanasius moved dramatically away from the interpretation of scriptural text, focusing rather on doctrinal positions that began and terminated with credal statements of faith. Athanasius’s career reflected, and more often catalyzed, the shift in scholastic method that underlies the Theodosian embrace of creeds and codes explored in Chapter 4. For this reason his literary oeuvre, and his impact on the rules and contents of debate in the aftermath of the Council of Nicaea, deserves special attention. The rise of the code perhaps wouldn’t, perhaps couldn’t, have occurred without him.

We see a bit of the young Athanasius, maybe in his mid-twenties, in a letter referred to by the first two words of its incipit: One Body. The letter is ascribed to Alexander of Alexandria but was likely written by Athanasius himself sometime between 318 and 324.Footnote ²⁷ This circular letter to all bishops was one of the “opening shots” of the Nicene controversy, and in it we see two strategies of truth production working together in support of Athanasius’s polemical ends. First, the letter begins by claiming to be centrally motivated by the Constantinian trope of divinely ordained unity:

That is, this public-facing document from the chancery of Alexander begins with an argument sure to find receptive ears in the imperial court; Athanasius told Constantine what he wanted to hear. Second, in One Body, scripture is used as check on credal statements. Specifically, scripture is invoked to falsify a negative creed that (Athanasius asserts) comprises “things that they assert upon discovery, going beyond scripture” (Urk. 4b.7). While the faulty “creed” states, for instance, that “the Word of God was not always in existence, but came into being from nothing” (Urk. 4b.7), Athanasius responds: “Who that hears John saying, ‘In the beginning was the Word,’ does not condemn those who say, ‘There was a time when the Word did not exist?’” (Urk. 4b.12).

The ultimate aim of One Body is to condemn heresy and to ostracize those who had been condemned, not to interpret scripture or to offer a positive statement of faith for the Universal (“Catholic” καθολική) community. According to Athanasius, the doctrines attributed to “those around Arius” cannot be true because their statements are falsifiable within the framework of scripture (Urk. 4b.11). He appeals to the authority of scripture for falsification but not for interpretation. In the words of Ellen Muehlberger: “In a way, [Athanasius’s] writings from the 320s and 330s ventriloquized his thoughts through Scripture, taking on the voice of Paul or the voice of the gospels to better say what his own exposition might also have expressed.”Footnote ²⁸

Athanasius wrote One Body as a young man, when battle lines of the controversy were still being drawn. At that point there was not even a common term to denote “Arius and those around him.” Thirty years had passed by the time that Athanasius penned the first full account of the Council of Nicaea, and in that interval the polemical and citational outlook had radically shifted.Footnote ²⁹ The struggle between Athanasius and George was so well known in Egypt that it filtered even into the rural areas, at least according to Constantius II’s letter to the Alexandrians in 357: “Even among those living on the frontier, who is ignorant of the rivalry in the events that have taken place?”Footnote ³⁰ The emperor wrote another letter that same year, addressed to coregents Aezenes and Sazanes, and claiming that news of Athanasius’s disgrace and exile had traversed the length of the Nile, all the way to the Kingdom of Axum.Footnote ³¹

The situation was dramatically different in the Latin West, where thirty years on, the Creed of Nicaea was still little known – even among the some of the most outspoken theological minds of the day.Footnote ³² As late as 359 the necessity of credal statements was not obvious, when Hilary’s exile led him to learn of the theological strife in the East and to write an extensive letter to Western bishops informing them of the dispute, apparently for the first time, and staking out his position on it.Footnote ³³ But in the Greek East, questions about it were hotly debated. “How was the Nicene Creed created? What is the nature of its authority? What is an Orthodox understanding of the relationship between the Nicene Creed and the scriptural texts that simultaneously interprets and constrains?” Answers to these questions had earned Athanasius two imperial exiles already. By the time another twenty years had passed, however, a Christian senator claimed confidently in a Latin treatise for the emperor that the Nicene Creed was not only universally applicable, but that it was written at a council attended by Christ himself!Footnote ³⁴ The story of Christian scholasticism over the fourth century is the story of the Nicene Creed’s rise from a distillation of scripture, to a check on scriptural interpretation, and finally to a universal statement by which all exegesis could be judged.

I turn now to Athanasius’s Letter Concerning the Decrees of the Council of Nicaea: the first full account of the council, composed likely during the bishop’s third exile (356–362).Footnote ³⁵ The main concern of Athanasius’s letter is to construct a new form of argument, one that is able to deal finally with the problem of “Arian”Footnote ³⁶ exegetes who justify heretical positions through exegesis of an underdetermined scriptural canon – a canon incapable of refuting Arian arguments once and for all because Arius’s supporters continually find new scriptures upon which to base their theological convictions.Footnote ³⁷ Athanasius knew the problem already in the 320s when he wrote One Body, and nevertheless intended to construct a creed based solely on the words of scripture. “We have often shamed these men by stating these things, and by opening up the divine scriptures for reading. But like chameleons, they morph themselves again” (Urk. 4b.16).

According to Athanasius, forty years later the problem was not solely the machinations of Arian interpreters. The problem, rather, was the nature of scripture itself. He begins his Letter Concerning the Decrees with a screed against those who focus on scriptural interpretation as a central site of theological contestation, and as a central framework for producing truth. These “chameleons” focus on scriptural interpretation “in extreme perverseness.” When they complain that the creed from Nicaea used terms not found in scripture, they “mutter like the Jews.”Footnote ³⁸ In typical style, the preface crescendos with Athanasius throwing scripture back at his enemies, paraphrasing Ezekiel 11:2. Heretics indeed do something “according to scripture,” he claims, “they have come to an inane conclusion” (1.2).

The problem was that Arians looked to scriptural interpretation as a primary scholastic tool and were, as such, “latter-day Judaizers” (2.1). They come to their position through both “ignorance of the truth and inexperience in divine scripture” – a phrase that is not simple hendiadys, or merely a rhetorical flourish (17.1). Rather, Athanasius argues that proper knowledge of the truth is pre-scriptural, or that truth is at least conceptually separable from scriptural interpretation. The truth, according to Athanasius, is the teaching handed down from the patrimony of the tradition with a unity of message, beginning with Moses and ending with the very wording of the Nicene Creed.Footnote ³⁹ Patrimony and scripture go hand in hand; one cannot exist without the other. This is not a position that Athanasius had always held, however – he came to it only later in life, in the 350s. Nor was it the position of the bishops attending the Council of Nicaea, upon entering the chambers in 325. Richard Vaggione summarized the situation succinctly:

According to Athanasius, the assembled bishops at Nicaea intended to compose a universally binding creed on the basis of scripture alone:

In this passage we see Athanasius admit the failure of scripture. As a scholastic method, textual interpretation alone was not sufficient to guarantee the production of true knowledge.Footnote ⁴¹ In light of this failure, Athanasius turns for the rest of his letter to the creation of a patrimony to support the language of the council, language that in the words of Lewis Ayres had become “verbal talismans” in the polemical debate that raged after the Council of Nicaea. “A term [ὁμοούσιος] originally chosen for polemical purposes and without any dense, well-established theological meaning was gradually identified as a key marker of pro-Nicene orthodoxy.”Footnote ⁴²

It is important to remember that this document, written in the mid to late 350s, contains the first significant use of the term “of the same substance (ὁμοούσιος)” by Athanasius – the word that would become the central point of contention for years to come, and that formed the battle line over which opposing factions were drawn up.Footnote ⁴³ Again in the words of Lewis Ayres:

It is important also to remember that Concerning the Decrees is polemical and creative. It is tempting to read Athanasius’s scholastic method in line with the modes of argumentation accepted by a later, more established orthodoxy, but his rhetorical strategy was radical and innovative; the treatise shows Athanasius inventing a new scholastic method by polemicizing against a group that, until very recently, was well within the bounds of “Catholic” Christianity. Éric Rebillard’s warning is apt: “scholars interested in Christian polemical debates in late antiquity must … be careful not to accept as a commonly held rule what was in fact being constructed as a polemical tool.”Footnote ⁴⁵

With the concluding twenty-one chapters of Concerning the Decrees, Athanasius responds to the failure of scriptural interpretation to answer the questions posed by the council, he briefly defends the metaphysics of the new credal language of “the same substance,” and he showcases extended quotations from Theognostus, Dionysius of Alexandria, and Origen that use the term “substance (οὐσία)” with his preferred valence. The reader is supposed to understand through Athanasius’s presentation that an Orthodox patrimony stretching back nearly two centuries stands behind the seemingly unprecedented language of the Nicene Creed. The apparent novelty of the definition is a mirage. “It is in this same sense that those gathered in Nicaea decreed these terms. But let us now prove that they did not invent these things and manufacture them on their own, as these ones allege, but spoke what they received from those before them. So this excuse also will be snatched away from them.”Footnote ⁴⁶

In Concerning the Decrees, Athanasius moves beyond his earlier position in which textual interpretation served as a check on and means of falsifying heretical doctrines. Here he marshals evidence of an orthodox patrimony in order to create a paratext for the scripture in a way that justifies the language of the council, most importantly the term “of the same substance (ὁμοούσιος).”Footnote ⁴⁷ He does this by offering calques on terms in scripture. For instance, he decrees that whenever the phrase “of the Father” refers to Jesus in a scriptural text, the reader should interpret as if it said “from the substance of the Father.”Footnote ⁴⁸ Bart Ehrman’s 1993 monograph The Orthodox Corruption of Scripture detailed editorial changes to the text of the New Testament in which late ancient scribes emended manuscripts to say what Orthodox readers knew them to mean. Already in the late 350s, however, Athanasius insisted that valid textual interpretation required an Orthodox corruption in the reading of scripture. His exposition of the Nicene Creed uses the rhetoric of scriptural interpretation and traditional authority to propose a radically new hermeneutic dogma, contriving an Orthodox patrimony for an utterly novel theological position and implementing a new scholarly method, along the way.

Athanasius and the “Canon”

Around fifteen years after he wrote his first full defense of the work of Nicaea in Concerning the Decrees, Athanasius wrote a festal letter laying out the “canonized” texts which constituted the “divine writings that we have for salvation.”Footnote ⁴⁹ Athanasius claims that he wrote the letter in response to the problem of “Melitians boasting about books that they call ‘apocryphal.’”Footnote ⁵⁰ The letter was written on the heels of Athanasius’ fifth (and final) exile, and sent to clerics as instruction regarding the manner in which scripture is to be used in their communities – a matter that required the bishop’s intervention, apparently.

Two observations will prove useful at this juncture: first, the extent of books that Athanasius deems “useful” includes books that are not within his canon.Footnote ⁵¹ At least one of these scriptures, the Shepherd of Hermas, was useful enough that Athanasius quoted it approvingly alongside the Letter of James in Concerning the Decrees, intending thereby to prove the Orthodox patrimony of his message (4). Second, Athanasius’s refutations of Arius from the 310s and 320s don’t evidence any confusion as to what group of texts are considered authoritative by all disputants involved; there is merely a dispute about how various statements in those texts are to be subordinated to one another. That is to say, already fifty years before Athanasius’s 39th Festal Letter, Christian theologians knew what constituted the “canon within the canon,” or passages and books of scripture that hold greater or lesser weight than others. The “canon” that Athanasius described in 367 is a corpus of quite a different sort; one that is permeable. There are books outside of the canon that are useful for newcomers, and books on the inside that are apparently not particularly useful for technical, elite theological debate.

This distinction helps me get at something central to the way that the Catholic scholars of the mid-fourth century interpreted text. In the wake of the decrees of Nicaea, the struggle over orthodoxy moved away from finding authoritative statements of doctrine within scriptural texts and instead toward justifying the language of the council’s pronouncements with reference to scriptural texts. The “canon” that Athanasius describes in his 39th Festal Letter comprises texts that are capable of being brought as evidence to check a credal statement. But by the time that he “defined” the canon in 367, he was doing quite the opposite in his polemical and protreptic scholarship: he was using credal statements – and above all the Nicene Creed – as a paratext and necessary precondition for authoritative interpretations of canonized scripture. The paratext that he offered had become the text.

This movement from paratext to text served to “canonize” not a particular set of scriptures, which had effectively already been done by the 320s at the latest, but rather to authorize a set of technical calques on scripture that govern its Orthodox interpretation. In the years after writing Concerning the Decrees, Athanasius regularly reaffirmed the apparently paradoxical position that all canonical texts were equally scripture, but that there was nevertheless a necessary, pre-textual understanding that served to guide any reading – and especially the reading of seemingly contradictory passages. For instance, in his Letters to Serapion, written during the course of his third exile (perhaps around 360) and thus at around the time that he composed Concerning the Decrees, Athanasius wrote:

The “distinctive character of Christianity” for Athanasius is pre-textual; interpreters must know the Orthodox tradition of interpretation in order to produce trustworthy knowledge. Part of that patrimony is to know that even when scripture says “the Lord created me,” the “me” that “was created” (ἐκτίσθη) is not “a created being” (κτίσμα). The semantic point may seem nonsensical, but for Athanasius, the Christological point stands.

Here we see that Athanasius is indebted to scholastic positions traceable to both Irenaeus and Tertullian. His definition of Orthodoxy stands in the gap between the two, and exploits strengths from each system, even though they are fundamentally incompatible. As I demonstrated in Chapter 2, Tertullian did not see scripture as a repository for truth, and held that its proper interpretation required assent to the regula fidei. In order to understand what scripture says, in other words, the exegete must already know what scripture means: for Tertullian this knowledge was the 116 words of the regula fidei, and for an older Athanasius, it was the Creed of Nicaea. But Athanasius also inherited a position from Irenaeus which Tertullian fundamentally rejected. Namely, Athanasius holds to the idea that truth is fractal: if the seeker is equipped with the right tools and hermeneutic strategies, truth can be continuously refined and examined to ever greater precision. For Irenaeus and Athanasius alike the question of the relationship between the Father and the Son is discoverable, and even while theological knowledge is progressively refined the nature of the message remains singular.

Concerning the Decrees

A newly minted theological method crystallized in and through Athanasius’s scholarly work. In Concerning the Decrees, Athanasius argues that an authoritative text has been distilled into the language of Nicaea and that the language of the distillate must be imposed as the authoritative framework for all subsequent reading. Credal language was reimposed on the authoritative text itself, rendering the words of scripture a simulacrum. Scriptural interpretation had become epistemically subsequent and methodologically ancillary. Through his polemics Athanasius achieved the irony of ironies: scriptural interpretation put itself out of business.Footnote ⁵⁴

Concerning the Decrees aims to construct a patrimony for the language of Nicaea and to justify the use of nonscriptural terms within a creed that claims to distill the language of scripture into an authoritative statement. Athanasius’s treatise includes a section of significant quotations of previous theological thinkers who use the “substance” language to speak of the relationship of the son to the father. He ends this section: “See, we are proving that this view has been transmitted to you from father to father. But you – latter-day Jews and disciples of Caiaphas – how many fathers can you assign to your phrases?” (27.4).

In Concerning the Decrees, Athanasius extensively cites previous authorities to demonstrate patrimony for the Nicene “substance” language, modeling a form of aggregation that would become the scholarly norm in decades to come. But the material form of Athanasius’s text also models a new scholastic method based in aggregation. His work was not solely a Christological treatise, it was the cover letter for a dossier. Athanasius appended a number of primary sources to the methodological exposition that we call Concerning the Decrees, beginning the text that was his main polemical adversary: Eusebius of Caesarea’s Letter to the Caesareans.Footnote ⁵⁵ A valid demonstration of theological truth, in Athanasius’ estimation, required first the sublimation of scripture to its distillate, along with a demonstration of the Orthodox patrimony of one’s ideas. But truly valid scholarship required one more step, as well: the aggregation of polemical referents, along with any material supporting or otherwise relevant to the question at hand. I argue that Athanasius’ creative work in treatises such as Concerning the Decrees set the standard for the production of valid theological knowledge.

It is precisely in this period, and in these letters, that Athanasius forged the polemical use of Nicene language, and it is only in the later fourth century that “Nicaea’s terminology gradually comes to be equated with Nicaea’s judgments.”Footnote ⁵⁶ Athanasius’s polemic was predicated on the failure of scriptural interpretation and the need to contrive an authoritative patrimony of unified, Orthodox voices in order to justify his own attachment to novel, nonscriptural language, and in order to respond to criticism that seemed to be coming at him from all sides.

The period between 350 and 367 was the most prolific of Athanasius’s life. In these years he forged not only a new mode of argumentation but also a literary reputation that led to his outsized influence on Nicene theological scholarship, and to his eventual canonization. Timothy Barnes lamented:

While I cannot chart with a Barnesian granularity the comings and goings of Athanasius during his most prolific period, I can say something about the work that he produced while he was on the lam: Athanasius’s constant rumination on the past, looking grievously backward on the Council of Nicaea and all of the perceived slights in the intervening years, shaped not only the Athanasius that was in exile but the Athanasius who was remembered in the Theodosian court as a “pillar of the church.” There may be no more consequential sense of bereavement in the history of the book than what is visible in the literature, and the structure of argumentation, that crystallized during the years when Athanasius first became a formidable literary figure. Athanasius’s dogged defense of the language and theology of Nicaea during this period set the standard for Christian theological disputation in the years that followed. His scholastic method quickly became customary.

Theologians defending the Nicene Creed were not the only polemicists who employed the method for which Athanasius’s Concerning the Decrees is our clearest example. There was an explosion of credal creation in the fourth century, on all sides of the debate, utilizing the same scholastic method of (1) aggregation of a scholastic patrimony, (2) distillation of the patrimony into a creed, and (3) sublimation of further dispute to the newly minted creed. The spate of creeds recorded in Athanasius’s Concerning the Councils in the early 360s – nearly a dozen – all reflect this same scholarly practice even when making opposite substantive claims. Add to this the fourth-century creeds extant in the later works of Socrates, Hilary, Theodoret, Epiphanius, and the various late ancient and early medieval collections, and it becomes clear that this method, which was created in defense of the Nicene Creed, quickly took over as the gold standard of scholastic methodology in fourth-century theological disputation, at least among theologians claiming Catholic identity.

Within seventy years the argumentative format that Athanasius pioneered in Concerning the Decrees, and reflected in the flurry of credal disputation in the 340s, 350s, and 360s, was wholly naturalized for theological disputation. In 434, Vincent of Lérins wrote matter-of-factly about the proper production of theological truth:

Conclusion

Athanasius’s work reflected and eventually catalyzed a shift across the domain of fourth-century theological scholarship, at least within the group of theologians disputing the legacy of Nicaea. He and his opponents agreed that the ultimate arbiters of truth were credal statements that had been distilled from authoritative archives, but that it was not sufficient simply to report the distillation of truth. Proper scholarly practice required that universal knowledge which was the result of aggregation be transmitted along with the aggregated sources themselves so that readers could “check the work” of the scholar, so to speak. In the early years of the Theodosian dynasty this mode of argumentation came to be the standard scholarly tactic for knowledge production – first in theological domains, and then everywhere. Pitched and often violent battles over Nicene orthodoxy during Athanasius’s lifetime set the stage for a new kind of scholastic tribalism in which Nicene Christians insisted that a scholastic method, born of polemic, was both true and universal.

It is no secret that the Theodosian dynasty was vehemently Nicene, and that the greatest influx of Christians into the ruling elite of Rome – the Old Rome and the New – occurred not under Constantine’s auspices but under Theodosius’s.Footnote ⁵⁹ The tenacity with which Theodosian dynasts patronized Nicene Christianity is evidenced not only in the building of churches, the elevation of senators, or the changing social mores regarding sex, family life, and Traditionalist worship. Even in the structure, motivations, execution, and reception of “secular” Theodosian scholastic productions we can trace a new scholarly method, born of the Nicene controversy.

By way of analogy, let’s engage with the judicial legacy of Antonin Scalia, the instigator and popularizer of a novel form of jurisprudence dubbed “originalism.” Imagine that Antonin Scalia served fifty years on the Supreme Court under a single president who packed the courts with originalist judges: jurists who take up Scalia’s scholastic method even when they disagree with his opinions. Twenty or thirty years later, it would not be terribly surprising if the “originalist” manner of argumentation found its way into new domains that have nothing to do with law.Footnote ⁶⁰ In such a world, “originalist philosophy,” or “originalist history,” or even “originalist journalism” might not seem so strange. Similarly, during the Theodosian dynasty, a powerful patronage system led a set of scholastic practices born of theological controversy to become embedded in the broader society. I argue that these practices are visible in Theodosian productions ranging from theological tractates to legal codifications to the Palestinian Talmud. In this sense, “Christianization” exists in practices. Even when Athanasius’s opponents disagreed with his theological claims, they mirrored back his argumentative method. As I argue in Chapter 5, even when some influential scholastic productions of the Theodosian Age reject or are ambivalent to Christian theological propositions, nevertheless we can see the effect of Christian scholastic methods in their form, content, and stated intentions. I turn now to the “rise of the code,” and to the changing shape of scholarship across the ideological spectrum during the Theodosian Age.
