Article Summary: This article plunges into the council of regensburg 792, where bishops, abbots, and royal envoys gathered in a Bavarian city to decide the fate of a controversial teaching about Christ. It reconstructs the political and spiritual landscape of Charlemagne’s empire, in which unity of faith was a tool of both salvation and governance. The narrative follows the spread of Adoptionism from the Iberian Peninsula to Regensburg, showing how an argument about Christ’s sonship became a test of loyalty to the Carolingian project. Through vivid scenes and historical figures, from Elipandus of Toledo to Alcuin of York, the story reveals the passions and fears driving this seemingly abstract dispute. The council of regensburg 792 is explored as both a moment of high theology and a very human drama of anxiety, ambition, and conviction. The article also traces how its decisions rippled outward, influencing later councils, Carolingian intellectual life, and the everyday faith of distant communities. By the end, readers see the council of regensburg 792 not as an isolated synod, but as a turning point in the shaping of Western orthodoxy and imperial identity. It is a reminder that ideas about God, when argued in stone halls under royal gaze, can redraw the maps of power and memory across centuries.

A Carolingian Summer in Bavaria: Setting the Stage in 792

The summer of 792 settled slowly over Regensburg, a city pressed against the banks of the Danube, where the waters carried rumors as easily as timber and grain. Smoke curled above wooden roofs and stone churches, and the sound of Latin psalms drifted from monasteries that had only recently taken root in this frontier of the Frankish world. Merchants haggled in a mixture of tongues—Latin, Old High German, Slavic dialects—each voice weaving another thread into the fragile fabric of Charlemagne’s empire. Yet behind this surface bustle, under the ringing of anvils and the soft murmur of prayer, another sound—quieter, sharper—could almost be heard: the low grind of argument about the nature of Christ.

By 792, Regensburg was no longer just a border town. It had become a strategic node in the expanding Carolingian realm, a place where Bavarian elites negotiated their place within a vast Christian empire. Royal messengers came and went along packed roads, carrying sealed letters, tax records, and, increasingly, theological texts. When word spread that a synod—a church council—to judge the teachings of certain Spanish bishops would be held here, the city tensed with a kind of curious expectancy. Something important was about to happen, something that would bind distant Spain to Bavarian soil through ink, parchment, and the spoken word.

The council of regensburg 792 did not burst into being as a spontaneous event. It was the culmination of months of correspondence, years of imperial ambition, and centuries of debate about who Christ truly was. Was he the eternal Son of God, one person with two natures, fully divine and fully human, as the great councils of Nicaea and Chalcedon had declared? Or, as some in Spain now suggested, was he in his humanity merely an “adopted” son, chosen and raised up by God, a man lifted into divine sonship? To most laypeople, these distinctions might have seemed remote, almost like distant storms over foreign hills. But to kings and bishops in the eighth century, such storms threatened to turn into tempests of war, schism, and rebellion.

On the eve of the gathering, the city’s clergy prepared guest quarters, aired out cloisters, and set extra tables in refectories. Monks in scriptoria sharpened their quills, for they would be called upon to record not only the proceedings but also the citations of Scripture and the Fathers that would fly back and forth like arrows in a skirmish. Somewhere, an archivist carefully laid out dog-eared copies of the creeds of Nicaea and Constantinople, volumes of Augustine and Gregory the Great, and the canons of earlier councils. The coming days would demand that memory and authority be summoned again, as if the whole Church’s past could be made present in a single room.

Bavarian nobles, too, had reason to watch closely. Their relationship with the Carolingian court was still relatively fresh, sealed by oaths, marriages, and the somewhat uneasy acceptance of Frankish overlordship. Religious orthodoxy, as defined by Charlemagne and his advisors, became another marker of loyalty. To stand on the wrong side of a doctrinal line was to risk being counted as suspect, even rebellious. It’s astonishing, isn’t it, how a question about the word “Son” in a creed could determine who held power south of the Danube?

So as the delegates approached Regensburg—bishops in dusty cloaks, abbots leading processions of monks, royal missi dominici carrying messages from Charlemagne—an invisible weight pressed down upon them. They came not simply to define doctrine but to decide what sort of empire this would be: fractured in belief or painfully unified; open to theological nuances or fearful of any deviation. The council of regensburg 792, held in this Bavarian city, would inscribe its answer into the memory of Western Christendom.

Charlemagne’s Vast Empire and the Search for Unity

To understand why a council in Regensburg mattered so much, one must first picture the empire that towered behind it like a vast, shadowy backdrop. Charlemagne’s rule stretched from the Atlantic to the fringes of Saxony, from the Pyrenees to the Alps and beyond. It was a tapestry of peoples—Franks, Lombards, Bavarians, Aquitanians, Saxons, and more—bound together by force, diplomacy, marriage alliances, and, crucially, by the promise of a shared faith.

Charlemagne did not see himself as a mere warlord who happened to believe in Christ. He fashioned himself as a new David, a king whose task was to shepherd a Christian people and defend the Church. If the Church’s teaching fractured, the kingdom’s unity might fracture with it. In this vision, councils like the council of regensburg 792 became political instruments as much as spiritual ones, tools for carving a stable identity out of dizzying diversity.

In royal capitularies, Charlemagne repeatedly insisted that correct doctrine and proper practice were not optional embellishments but foundations of order. He ordered priests to be educated, monasteries to adhere to communal rules, and bishops to ensure that peasants understood at least the rudiments of the creed. This was an era when sermons against drunkenness might sit alongside exhortations to accept the decrees of distant ecumenical councils. For the emperor, the line between moral discipline and doctrinal purity blurred; both undergirded his Christian realm.

The empire’s scale, however, brought complexity. On its fringes lay old kingdoms with their own roots—Lombard Italy, with a long history of theological disputes, and the Spanish territories under Muslim rule but still thick with Christian memory, liturgy, and bishops. Messages from these lands arrived in Aachen or Worms months after they were written. Rumors travelled faster than letters; misunderstandings faster than careful explanations. In this world of slow travel and fragile communication, any hint of heresy carried a special menace. Could one trust that the distant churches truly confessed what the king and his bishops confessed at the imperial center?

It was into this nervous climate that reports of Adoptionism flowed. In the Iberian Peninsula, under the shadow of the Umayyad emirate of Córdoba, Christian communities had been wrestling with Islamic monotheism, Jewish traditions, and their own Visigothic heritage. Some of their bishops, trying to explain Christ’s mystery in fresh ways, began to speak of his humanity as “adopted” by God. That nuance might have made some sense in their local debates. But to Frankish ears, it sounded ominously like a betrayal of Nicaea and Chalcedon.

Charlemagne’s advisors—scholars like Alcuin of York, theologian-bishops in Gaul and Germany—heard in Adoptionism an echo of older, condemned ideas, such as Nestorianism, which had seemed to divide Christ into two persons, human and divine. They remembered the long battles over Arianism, in which Christ’s true divinity had been denied or diminished. A new formula that called Christ “adopted” in his humanity seemed too close for comfort to those ancient enemies. If kingship depended on reflecting Christ the King, what did it mean if Christ’s identity itself seemed unstable?

So the search for unity became a race against doctrinal ambiguity. Charlemagne could not allow part of his sphere of influence—whether in Spain or Bavaria—to drift into theological experimentation that might undermine his carefully shaped Christian empire. The council of regensburg 792 emerged from this tension: an attempt to pin down language, to patrol the borders of acceptable belief, and to make clear that within this empire, even the way one spoke of Christ’s childhood and manhood was subject to royal concern.

Adoptionism Emerges: A Controversial Christ in the West

Adoptionism did not announce itself with trumpets. It arose, quietly at first, from sermons and commentaries, from bishops who wrestled with Scripture and tradition in the changing world of early medieval Spain. They read in the Gospels about Jesus growing “in wisdom and stature” (Luke 2:52), about his baptism in the Jordan, when the heavenly voice declared, “You are my beloved Son.” These episodes, viewed through their particular lens, seemed to point to a progressive elevation of Christ’s humanity, as if God were, in some sense, adopting the man Jesus into sonship.

Central to Adoptionism was a distinction between Christ’s eternal divine sonship—acknowledged by all orthodox Christians—and his human sonship. Spanish proponents, such as Elipandus of Toledo and Felix of Urgell, tried to protect God’s transcendence and freedom by saying that in his humanity, Christ was son “by adoption.” In their minds, this did not deny his divinity; it honored God’s sovereign decision to exalt a truly human life. But nuance is a fragile thing, easily cracked when it travels across mountains and borders.

When this teaching reached learned clerics north of the Pyrenees, it quickly acquired a different hue. To them, calling Christ’s humanity “adopted” sounded like implying that there was a time when Christ was not the Son in his fullness, or that the human Jesus was a kind of separate person elevated alongside the divine Word. That, they believed, reopened doors the Church had fought hard to close. Councils in the fourth and fifth centuries had already rejected such divisions, insisting on the unity of Christ’s person.

Moreover, the term “adoption” carried ordinary connotations that made the doctrine appear problematic in the eyes of Frankish theologians. To adopt a child, in human legal practice, was to bring someone not originally of one’s blood into the family. But if Christ’s humanity were “adopted,” what did that imply about the Incarnation itself? Was the Word of God merely inhabiting a man chosen from outside the divine life, rather than becoming flesh in the mystery of Mary’s womb? To men like Alcuin, such a thought threatened to unravel their entire understanding of salvation.

The theology of the eighth century was not an ivory-tower affair. Preachers tried to explain to illiterate congregations who Jesus was and why his life mattered. If some clergy began to speak too freely of “adopted sonship,” fear arose that ordinary believers might come to think of Christ as less than fully divine or as a sort of hero promoted to divine rank. In a world where Christian identity underpinned law, kingship, and social hierarchy, such confusion was intolerable. The church, they believed, must speak with one voice about the one Christ.

As the debate sharpened, letters crossed mountains and rivers. Bishops asked colleagues for opinions; theologians drafted refutations. The dispute crystallized around certain Latin formulas, small turns of phrase that, in those days, carried almost as much weight as armies. The council of regensburg 792 did not invent the opposition to Adoptionism, but it became one of the crucibles in which that opposition took institutional form—a moment when the Church of the Franks said, in effect, “Here, in this land, there shall be no adopted Christ.”

From Toledo to Regensburg: How a Spanish Dispute Reached Bavaria

To follow the path from Toledo to Regensburg is to trace the journey of ideas through a Europe that often seems deceptively small on our maps. In reality, it took weeks, sometimes months, for letters to travel from the plains of Castile to the valleys of the Danube. Along the way they passed from one trembling hand to another: monks at border monasteries, messengers changing horses at royal stations, bishops pausing under oak trees to read, with furrowed brows, the latest theological developments from the south.

Toledo, though under Muslim political rule by the late eighth century, still functioned as a spiritual center for many Christians in Iberia. Its archbishop, Elipandus, inherited not only a see but a tradition, stretching back through the Visigothic councils that had once legislated for an entire kingdom. When Elipandus began to use adoptionist language about Christ, his words did not remain local. They were copied, commented upon, and occasionally contested within the networks of Iberian Christianity.

Somewhere along this chain, Frankish observers entered the scene. Perhaps a pilgrim, returning from a visit to Spanish shrines, carried back an unsettling sermon. Perhaps a scholar, traveling through Aquitaine, heard a rumor of doctrinal “innovation” to the south. However it happened, by the 780s, the Frankish Church became aware that something was stirring in Spain that required attention. The stakes were heightened by politics: Charlemagne had intervened militarily in the region, seizing territories in the northeast and forging ties with certain Christian communities who saw in him a protector against Córdoba.

If those same Christians appeared, now, to harbor questionable doctrines about Christ, what did that say about the reliability of allies on the Spanish frontier? A religious flaw in one corner of the map might translate, in the emperor’s mind, into a political vulnerability. The Frankish Church became, in effect, the empire’s theological early-warning system. Reports of Adoptionism prompted a flurry of letters and eventually the convening of synods in places like Regensburg, Frankfurt, and Aachen, where bishops tried to articulate a firm, unified response.

In this sense, the council of regensburg 792 was one node in a network of councils responding to a dispute born far away. Here in Bavaria, bishops could show both their loyalty to Charlemagne and their participation in the wider Latin Church by condemning what Rome and key Frankish theologians regarded as heresy. Geography did not protect Spain from the judgment of Bavarian prelates; nor did distance prevent the echo of their anathemas from reaching Toledo and Urgell.

The trail from Toledo to Regensburg also illuminates the fragile unity of the western Church in an age before centralized bureaucracy. There was no single office that instantly dealt with doctrinal controversies. Instead, there were webs of correspondence, personal reputations, and regional councils. A bishop’s words in one land could eventually be weighed, debated, and condemned by bishops in another, hundreds of leagues away, because the Church’s memory, carried in manuscripts and liturgy, connected them. One of the quiet miracles of this age is that such connections, though slow and often threatened, held firm enough that a theological phrase in Iberia could provoke a synod in distant Bavaria.

When, later, chroniclers noted the council’s decisions, they did so with an awareness that Regensburg was participating in a story much larger than itself. This was not simply a local Bavarian matter; it was part of a pan-Western effort to define, once more, what could and could not be said about the Son of God. The dusty roads from Toledo to Regensburg may have been long and dangerous, but the ideas carried upon them would travel very far indeed.

The Road to the Council of Regensburg 792

By the late 780s and early 790s, the controversy over Adoptionism had matured from whispers into a full-blown conflict of letters and treatises. Felix of Urgell, a bishop in the Pyrenean region loyal to Charlemagne, had embraced the adoptionist formulas with enthusiasm. His position was particularly troubling to the Frankish court: he was not some distant, unaffiliated Iberian cleric, but part of the Carolingian world itself. If Felix went astray, it meant that the infection of error had reached into the emperor’s own ecclesiastical household.

Efforts were made to persuade Felix and his allies. Theologians wrote refutations; councils elsewhere issued condemnations. According to later accounts, Felix appeared at the court and debated before learned bishops, perhaps even submitting—at least outwardly—to correction. Yet his adherence to adoptionist language did not simply evaporate. The issue simmered on, becoming an embarrassment and a warning sign. It demonstrated that even bishops close to the imperial center could diverge from the official line if not carefully guided and, if necessary, rebuked.

The council of regensburg 792 emerged, in part, as a response to this ongoing irritation. Bavaria, recently integrated more tightly into the Frankish sphere after the fall of the Agilolfing dukes, needed both doctrinal alignment and political reassurance. Holding a council there signaled trust in Bavarian bishops while also reminding them that Rome and Aachen watched closely. It was a delicate dance: empower regional churches, but bind them firmly to the imperial and universal norm.

Preparations for the council would have involved not only logistics but also intellectual groundwork. Royal envoys might have arrived with copies of earlier anti-adoptionist decisions, model anathemas, and extracts from the Church Fathers emphasizing Christ’s unique, eternal sonship. Local bishops would have consulted their own libraries, perhaps sending to nearby monasteries for hard-to-find texts. Debate was not to be improvised; it would stand upon the shoulders of centuries of reflection.

We can imagine discreet conversations in cloisters and courtyards in the weeks before the formal sessions opened. Some bishops may have been only vaguely familiar with the details of the Spanish dispute; others might have already formed strong opinions. A few, perhaps, sympathized with the desire of Elipandus and Felix to speak dynamically about Christ’s humanity in relation to God’s fatherhood, yet feared where the language might lead. Consensus was not guaranteed, and the Council would have to forge it, line by painstaking line.

The date, 792, is not incidental. Charlemagne’s reign was at a critical juncture. He had recently faced internal challenges, including the rebellion and tragic death of his son Pippin the Hunchback. The empire’s external enemies, from the Saxons in the north to various Slavic and Avar groups in the east, demanded constant attention. Amid these pressures, a clear, uncompromising statement on Christology could serve as both theological anchor and political rallying point. His empire might struggle at its borders, but at its heart—its understanding of Christ—there must be no ambiguity.

Thus, when the bishops and abbots finally assembled, the atmosphere carried a sense of destiny. They were not merely tidying up a minor doctrinal wrinkle; they were, as they saw it, defending the truth that undergirded every baptism, every Mass, every coronation. In the great and terrible economy of the eighth century, to err about Christ was to risk countless souls—and perhaps even the favor of God upon the empire itself.

Inside the Council Chamber: Bishops, Books, and Burning Questions

The council chamber in Regensburg was likely a large hall, perhaps attached to a church or episcopal residence, its thick walls dimming the outside clamor. Light filtered in through narrow windows, catching the dust that rose with every shuffle of sandals and boots across the flagged floor. Bishops sat in their appointed places, robes gathered around them, croziers resting within arm’s reach. Between them and at the front stood tables crowded with codices: Scripture, conciliar canons, patristic homilies, perhaps even Latin translations of Greek theologians.

The proceedings opened with prayer—solemn, chanted, invoking the Holy Spirit to guide their discernment. Invocations of earlier councils, like Nicaea and Chalcedon, reminded everyone that they were not creating the faith anew, but receiving and defending it. The secretary or notary would have sat ready, stylus poised, to record the deliberations, while attendants brought forth documents as requested, turning brittle pages with cautious fingers.

One can imagine the first key question posed in the hall: What exactly had Elipandus and Felix said? Their letters or summaries of their positions would be read aloud in careful Latin, so that every ear could hear the disputed phrases. The room listened: “Christ, as man, is son by adoption”—or some similar formulation. Murmurs rippled through the assembly. Some faces tightened in disapproval; others nodded gravely, already marshaling counterarguments.

Then came the rebuttals. Bishops and theologians rose, one after another, to cite Scripture: the Prologue of John’s Gospel, proclaiming the Word who “was with God, and was God”; the baptismal theophany, the Transfiguration, the Resurrection accounts that revealed Christ’s unique identity. They quoted the creed: “Begotten, not made, consubstantial with the Father.” They recalled the Council of Ephesus, which had insisted that Mary be called Theotokos, “God-bearer,” as a safeguard for Christ’s unity. To call Christ “adopted” in his humanity, they argued, threatened to unsettle the Church’s confession of the one Lord Jesus Christ.

The tone was not merely academic. Voices rose in earnestness. These men believed that the spiritual safety of their people depended on their clarity. They tried to imagine how their words would sound in the mouths of village priests, preaching to congregations of farmers and craftsmen. Would those listeners still perceive a single Christ, fully divine and fully human, or begin to think of a man raised to divine rank by merit? The bishops strained to close every door through which confusion might slip.

At intervals, the council probably paused to examine authorities: Augustine on the Incarnation, Leo the Great’s famous Tome to Flavian, which had been so important at Chalcedon. A scribe might read a passage, and then a bishop would explain how it cut against the adoptionist formulas. The chant of citations, the call-and-response of text and interpretation, gave the council its rhythm. This was, in a sense, a liturgy of doctrine, with its own solemnity and ritual.

Behind the formalities, personal stakes were high. Some bishops had corresponded with Felix or Elipandus; condemning their teaching felt like a rebuke of old colleagues. Others perhaps feared that too harsh a judgment might push Spanish Christians further away, making reconciliation harder. Yet the majority discerned that compromise here would only deepen the wound. As one later chronicler might paraphrase their logic: false mercy toward heresy is cruelty toward the faithful.

Hour by hour, day by day, the lines of the council’s eventual condemnation emerged, shaped by argument, prayer, and the weight of tradition. And always, at the back of the chamber, loomed the expectation of the emperor, even if Charlemagne himself was not physically present. His desire for doctrinal purity pressed upon them like a silent, unspoken command.

Human Faces of a Theological War: Elipandus, Felix, and Alcuin

To write only of councils and canons is to risk flattening the story into abstractions. The controversy that culminated in the council of regensburg 792 was also a drama of individuals—of aging bishops, brilliant scholars, and deeply pious men who nonetheless found themselves on opposite sides of a hardening line.

Elipandus of Toledo, by the time his teachings came under severe scrutiny, was an old man. He had spent decades shepherding a Christian flock under Muslim rule, negotiating with emirs, preserving liturgical traditions, and defending his community’s identity in a complex, often hostile environment. One can imagine him in his study, parchment spread out, pen in hand, striving to articulate how Christ could be both truly human and the saving Son of God in terms that would make sense to his people. For Elipandus, to call Christ “adopted” in his humanity may have seemed a way to stress the reality of the Incarnation: a true man, raised and embraced by God.

Felix of Urgell presents a different portrait: a frontier bishop, serving in lands newly drawn into the Carolingian orbit, caught between worlds. He owed allegiance to Charlemagne but drew inspiration from Spanish theological currents. When he adopted adoptionist language, it was not in defiance, at least not initially, but in the conviction that he was upholding a legitimate theological opinion. The subsequent accusations of heresy must have struck him with a mixture of shock and indignation. To be summoned, questioned, and pressed to recant would have felt like being torn between conscience and obedience.

On the other side stood figures like Alcuin of York, the Northumbrian scholar whom Charlemagne had brought to his court as a kind of intellectual architect. Alcuin had bathed in the patristic heritage of the Latin West; Augustine, Ambrose, and Gregory were his daily companions. To him, the adoptionist formulas were not clever pastoral tools but dangerous cracks in the wall of orthodoxy. In a letter to Felix, Alcuin argued passionately, appealing to both logic and tradition. He could not accept a Christ whose humanity was in any sense “adopted,” because it risked dividing the person of Jesus and undermining the unbroken confession of the creeds.

It is easy, with hindsight, to cast Alcuin as the hero and Elipandus and Felix as the villains. But history, when looked at closely, resists such simple plots. All three men were sincere, learned, and devoted to Christ as they understood him. All three believed they were serving the Church. Their clash reveals how difficult it could be, in this era, to hold together local pastoral needs and universal doctrinal norms, personal insight and communal obedience.

Alcuin’s letters reverberated through councils like Regensburg. His mastery of Scripture and the Fathers provided ammunition for anti-adoptionist arguments; his reputation added weight to the condemnations. Yet he, too, must have felt the strain of condemning fellow bishops. The pen can be as heavy as the sword when it is used to sever a man from what is declared to be the truth.

In the end, the council of regensburg 792 would side decisively with Alcuin’s camp, but the existence of men like Elipandus and Felix reminds us that heresy, in the eyes of the Church, is often the shadow cast by fervent attempts to understand God. Their names, preserved in both condemnation and commentary, give the narrative a human face: aging hands writing disputed phrases; brows furrowed in debate; hearts torn between the desire to be faithful and the fear of being found in error.

Debating Christ: Nature, Person, and the Heart of Adoptionism

At the core of the Regensburg deliberations lay a set of questions as simple to articulate as they were profound to answer: Who is Jesus Christ? In what sense is he Son of God? How do his humanity and divinity coexist without confusion or separation? The debate may sound arcane, yet for the bishops of 792, these questions touched on salvation itself. If Christ were not who the Church claimed he was, could he truly save?

The anti-adoptionist position, which the council of regensburg 792 would ultimately adopt, leaned heavily on the language and concepts hammered out at earlier ecumenical councils. Christ was one person, the eternal Word of God, who had assumed a complete human nature—body and rational soul—without ceasing to be divine. In him there were two natures, divine and human, but these were united in a single person or hypostasis. To speak of the human Christ as “adopted” risked, they argued, dividing the person, as if there were a human subject alongside the divine Word.

Adoptionists insisted that they, too, upheld Christ’s unity. They wanted to emphasize that his humanity was real, not a mask, and that his human life unfolded in time, growing, learning, even “meriting” in some sense the glorification that followed. But the word “adoption,” with its legal connotations, seemed to imply that God’s sonship was conferred on a human subject from outside. The Council judged that this could not be reconciled with the Church’s confession of the eternal Son who became flesh.

Scripture was, of course, the primary arena of argument. Opponents of Adoptionism pointed to passages like John 1: “In the beginning was the Word,” and Hebrews 1, which speaks of the Son as the one through whom God made the ages. Such texts, they claimed, left no room for a Christ whose sonship, in any registered sense, began in time as an act of adoption. They also cited baptismal and conciliar formulas that spoke of one Lord Jesus Christ, begotten of the Father before all ages.

Patristic citations strengthened the case. Augustine’s insistence that the same person who was born of the Father before all ages was born of Mary in time became a cornerstone. Gregory the Great’s homilies, already cherished in the Frankish world, were mined for phrases that underscored the unity of Christ’s person. A later chronicler would note that the bishops “judged in accordance with the holy Fathers,” a reminder that novelty in speaking about Christ was itself suspect. “We preach no other Christ than the one handed down,” became an implicit rallying cry.

Yet behind these conceptual and textual maneuvers lay pastoral concerns. If one granted that Christ’s humanity could be called “adopted,” what of the faithful who, through baptism, were also described as adopted children of God? How would they perceive their relationship to Christ the Son? Orthodoxy required that believers see themselves as adopted into the Son’s unique filiation, sharing by grace what he possesses by nature. If Christ’s humanity were also adopted, the distinction between the head and the members might blur in unsettling ways.

Thus the council’s eventual declarations did more than condemn a phrase; they strove to protect an entire vision of Christian life. To say, as they did, that Christ could not be called “adopted” in his humanity was to insist that the one who saves is always, in every aspect, the eternal Son made flesh. From this flowed the faithful’s hope: that in him, they too would become children of God, not as parallel adoptees but as members of his body, sharing the sonship that is his by right.

Charlemagne’s Invisible Hand: Power, Piety, and Politics

Charlemagne’s presence at the council of regensburg 792 is, in many respects, spectral. Whether or not he attended in person, his will hovered over the proceedings like a stern but unseen judge. The emperor had long cultivated an image as both defensor ecclesiae—the defender of the Church—and as its internal reformer. He summoned councils, approved their acts, and sometimes pressed them to be bolder in condemning error.

For Charlemagne, theology and politics were deeply intertwined. A unified faith could knit together peoples as diverse as the Franks, Lombards, and Bavarians; it could also legitimate his expansion into regions like northern Spain. If the Church within his borders spoke with one voice about Christ, then dissenting voices, especially in contested borderlands, could more easily be labeled as outsiders, even enemies. A clear condemnation of Adoptionism at Regensburg and elsewhere helped draw an invisible boundary of orthodoxy that, in many cases, overlapped with the boundaries of Carolingian influence.

Charlemagne’s advisors understood this dual utility of doctrine. Alcuin and others not only drafted theological refutations but also framed them in ways that reinforced imperial authority. By associating Adoptionism with regions less fully integrated into the Carolingian order, they subtly portrayed orthodoxy as a mark of civilized, loyal, and properly governed Christian society. To be in communion with the Carolingian Church was to be on the right side of history and salvation.

Yet we should not reduce Charlemagne’s role to cynical manipulation. Contemporary accounts emphasize his genuine concern for correct belief. In the royal mind, error about Christ was not just a political nuisance; it risked divine wrath, which could manifest in military defeats, famines, or internal rebellions. To purge heresy was to seek God’s favor on the realm. The king who built churches and endowed monasteries also felt compelled to uproot teachings that threatened the coherence of the faith he so arduously promoted.

Nevertheless, the power dynamics are inescapable. Bishops at Regensburg deliberated under the tacit understanding that their conclusions would be weighed in Aachen. A council that failed to condemn what the emperor and his chief theologians already viewed as heresy might find itself marginalized or even reprimanded. On the other hand, a firm condemnation would likely win royal approval, favor, and possibly material support for local ecclesiastical projects.

In this light, the council of regensburg 792 becomes an example of what one might call “imperial orthodoxy in action”—a process in which theological precision and political consolidation advanced hand in hand. When the bishops put their seals to the canons and anathemas, they were not only safeguarding doctrine; they were also, perhaps unwittingly, strengthening the ideological spine of an empire that aspired to Christian universality.

The Condemnation Pronounced: Anathemas in Regensburg

The climactic moment of the council came when, after days of deliberation and citation, the bishops drafted and pronounced their formal sentence against Adoptionism. The language, as far as later sources allow us to glimpse it, was stark and uncompromising. They anathematized those who claimed that Christ, “according to his humanity,” could be called an adopted son of God. Such formulas, they declared, were contrary to Scripture and the tradition of the Fathers.

We can imagine the scene: a scribe reading the draft aloud, the assembly listening, some nodding in assent, others scanning the text with careful eyes. Adjustments might be made—a word sharpened here, a citation strengthened there—until the canons met the council’s collective judgment. Then, one by one, bishops stepped forward to sign or affix their mark, a ritual that turned ink into authority. Each signature was a pledge: “I, N., agree that this is the faith of the Church and the standard for my flock.”

Felix and Elipandus, though not present, were named as the principal exponents of the condemned teaching. Their writings were labeled as erroneous, their interpretations rejected. In that moment, their long labors as teachers and pastors were, in effect, publicly disowned by a major assembly of the western Church. The personal cost, for them and their supporters, must have been immense—even if they only heard the news months later, carried across mountain passes by couriers who had never seen Toledo or Urgell.

But for the majority at Regensburg, the condemnation brought relief. Ambiguity lifted; the line separating orthodoxy from error had been redrawn with heavy strokes. Priests could now preach and teach with the authority of a council at their back. When confronted with texts or travelers from Spain that spoke of Christ as “adopted” in his humanity, they could point to the canons of 792 and say: “The Church, guided by the Holy Spirit, has judged otherwise.”

The council’s acts did not remain in Regensburg. Copies were made, laboriously, by monastic scribes. These were dispatched to other sees, to monasteries, perhaps even to the royal court. Their words entered the bloodstream of Carolingian Christianity, to be cited and reaffirmed at later gatherings, such as the Council of Frankfurt in 794. In a world without printing presses, every manuscript carrying the council’s decisions was a fragile vessel of memory, yet enough of them survived—or their substance did—that Regensburg’s condemnation became part of the Church’s enduring stance.

One later chronicler, in a narrative preserved in a monastic library, summarized the spirit of such councils with a telling phrase: “Thus was error put to flight, and the truth of the Incarnation shone forth with greater clarity.” Whether we hear in that line pious exaggeration or genuine gratitude, it captures how many in the eighth and ninth centuries interpreted events like the council of regensburg 792. The anathemas were not, in their eyes, acts of cruelty but of healing—a surgeon’s cut to excise a dangerous growth from the body of Christendom.

Echoes Beyond Bavaria: From Regensburg to Rome and Aachen

The council’s work might have ended within the walls of Regensburg, but its consequences did not. The decisions taken there traveled outward, intersecting with other centers of power and reflection—most notably Rome and the imperial court at Aachen. The Carolingian world was increasingly accustomed to thinking in terms of a shared Latin Christendom, in which local councils contributed to, and drew strength from, a broader consensus overseen by both pope and emperor.

Rome, though geographically distant, maintained a symbolic and legal primacy. Popes had to reckon with the theological positions emerging from the lands of the Franks, particularly as Charlemagne’s influence grew. The condemnation of Adoptionism at Regensburg and subsequent councils aligned with Roman concerns to safeguard the Nicene-Chalcedonian heritage. Papal letters would, in time, echo these anti-adoptionist judgments, creating a feedback loop of mutual reinforcement.

Aachen, as Charlemagne’s favored residence and the heart of his reforming projects, became the place where theological decisions were digested, systematized, and integrated into imperial policy. At the Council of Frankfurt in 794, for example, bishops from across the empire gathered under Charlemagne’s gaze to address several issues, including Adoptionism. The Regensburg condemnations contributed to the materials on which Frankfurt built, helping to cement a unified, empire-wide rejection of the doctrine.

In this way, the council of regensburg 792 functioned as an early trumpet in a larger choir. Its voice was not solitary; it harmonized with, and was amplified by, subsequent gatherings. Over the next decades, as Carolingian intellectual life blossomed, scholars produced more systematic Christological reflections, drawing on the decisions of these synods as fixed points. What had once been a contested question about how to speak of Christ’s humanity and sonship became, slowly but surely, a closed case in the Latin West.

The echoes reached even into the monastic schools where young clerics were formed. They learned, not through first-hand exposure to Spanish texts, but through compendia and summaries that presented Adoptionism as a defeated error. Their teachers, citing councils like Regensburg, would use the controversy as a kind of cautionary tale: this is what happens when one steps outside the language of the Fathers and the creeds. Thus, long after the original protagonists had died, their names and ideas survived as warnings, framed within narratives of orthodox victory.

Rome, Aachen, and Regensburg together illustrate how, in the late eighth century, doctrinal unity was not decreed in a single stroke but woven through a series of overlapping decisions and confirmations. Each council added another layer of certainty, another line in the story that defined the West’s understanding of Christ. The council of regensburg 792 may seem, at first glance, a provincial episode in Bavarial history; in fact, it was a crucial thread in the tapestry of medieval Christendom.

The Council and the Making of Carolingian Orthodoxy

Orthodoxy, in the Carolingian world, was not a static inheritance but a dynamic project. Charlemagne and his successors did not merely receive the faith; they curated, clarified, and, in some ways, reshaped it for their time and place. Councils like Regensburg were workshops where this process unfolded, as bishops hammered doctrinal metal into forms suited for both theological clarity and imperial cohesion.

The condemnation of Adoptionism at the council of regensburg 792 contributed significantly to what modern historians often call “Carolingian orthodoxy.” This was a distinct, though deeply traditional, articulation of Christian belief that emphasized continuity with the early councils while also reflecting the specific concerns of a vast, Latin-speaking empire. Its Christology stressed the unbroken sonship of Christ, the unity of his person, and the fittingness of his dual nature for the work of salvation.

In practice, this meant that certain ways of speaking about Christ were locked in as normative, while others—like the adoptionist formulas—were excluded. The boundaries of acceptable discourse narrowed, but within those boundaries a rich intellectual life blossomed. Theologians could explore the implications of the Incarnation for liturgy, for moral life, and for political authority, confident that the basic parameters of Christ’s identity were settled.

One can see the fruits of this in Carolingian exegesis, where Christ appears not only as the Redeemer but as the archetype of the Christian king and the Church itself. The certainty that he was the eternal Son in human flesh allowed preachers and commentators to draw powerful analogies between his humility and exaltation and the ideals of Christian rulership. The emperor, like Christ, was to be both servant and lord, humble in piety yet exalted in office. To tamper with Christ’s sonship threatened this entire symbolic edifice.

Moreover, the stamping out of Adoptionism reinforced the Carolingians’ self-perception as guardians of orthodoxy, especially in contrast to both the Byzantine East and the Islamic world. At a time when the iconoclastic controversies were roiling the Greek-speaking Church, Latin theologians prided themselves on fidelity to the Incarnate Word in all his fullness. Adoptionism seemed, to them, a step toward dissolving that fullness—a step they refused to tolerate. Their resistance became part of a broader narrative in which the Frankish-led West emerged as a bulwark of correct doctrine.

Thus, Regensburg’s decisions fed into a larger, self-reinforcing cycle. Councils defined orthodoxy; rulers enforced it; theologians celebrated and expounded it; and subsequent generations inherited it as the unquestioned framework of their faith. The council of regensburg 792 may have been one waypoint among many, but without such waypoints, the road of Carolingian orthodoxy would not have been so clearly marked.

Ordinary Believers and Distant Frontiers: How Doctrine Traveled

When bishops signed the canons at Regensburg, few peasants in remote Bavarian valleys or on the Spanish frontier had any direct awareness of what had transpired. They were more immediately concerned with harvests, taxes, and the turn of the seasons. Yet, over time, the council’s decisions trickled down into their lives, shaping the prayers they heard, the homilies they listened to, and even the images before which they knelt.

The primary conduit for this transmission was the parish priest, often poorly educated by later standards but nonetheless the chief interpreter of Christianity for his flock. After Regensburg, priests in the Carolingian realms would be instructed, through diocesan synods and episcopal directives, to avoid language that smacked of Adoptionism. They were to emphasize that Christ was the eternal Son who had become man for humanity’s salvation, not a man raised to divine rank as an adopted child of God.

Such emphases might appear in catechetical explanations to those preparing for baptism, in brief expositions of the creed recited at Mass, or in seasonal sermons—especially at Christmas and Epiphany, feasts rich with themes of Christ’s manifestation as Son. The subtle influence of the council of regensburg 792 can thus be discerned, not in grand treatises alone, but in how villagers gradually learned to imagine the figure at the center of their faith.

On distant frontiers, where Christian and non-Christian populations mingled, the council’s impact was even more strategic. Missionaries in Saxony or among Slavic peoples needed a clear, non-negotiable message about who Christ was. Confusion or divergence might weaken their efforts to distinguish Christian belief from local pagan traditions or from the teachings of neighboring religions. The tidy rejection of Adoptionism simplified their task. There would be no room, in their preaching, for Christ as a mere holy man elevated by God; he must be proclaimed as God’s own Son in human flesh.

The contrast was particularly sharp in regions bordering the Islamic world. Muslim theologians, affirming Jesus as a prophet but denying his divinity, posed an intellectual challenge to Christian communities. In this context, any teaching that seemed to reduce or relativize Christ’s sonship could be exploited by Muslim critics as evidence of Christian inconsistency. Carolingian insistence on a robust, unqualified Christology thus served as an apologetic shield as well as an internal norm.

Behind these grand narratives, however, we can still glimpse the small, poignant moments in which doctrine touched individual lives: a mother teaching her child to make the sign of the cross “in the name of the Father, and of the Son, and of the Holy Spirit”; a dying man repeating the creed with his priest, trusting that the Christ he confessed was powerful enough to carry him through death; a community gathering around a crucifix, seeing in the tortured figure not an adopted hero but the very Son of God who had shared their suffering. These everyday acts of faith were, in their own way, the living echo of decisions made in halls like that of Regensburg.

Manuscripts, Margins, and Memory: Preserving the Council’s Voice

Without parchment and ink, the words spoken at Regensburg would have vanished like smoke. The survival of the council’s decisions depended on a chain of fragile, labor-intensive acts: drafting, copying, correcting, and preserving manuscripts. In monasteries across the empire, scribes bent over desks, quills in hand, painstakingly reproducing the canons and associated texts that enshrined the condemnation of Adoptionism.

These manuscripts were not mere duplicates; each was a new performance of memory. A scribe in Fulda or Reichenau might copy the acts of the council of regensburg 792 alongside other conciliar decrees, capitularies, and patristic excerpts, creating compendia that served as reference works for bishops and abbots. Marginal notes sometimes revealed how later readers interpreted or expanded upon the original decisions. “Note,” a scribe might write in cramped letters, “how this canon aligns with the teaching of blessed Augustine,” or “This error was also refuted at Frankfurt.”

Occasionally, manuscripts fell victim to time: ink faded, pages were lost, bindings tore. Some were scraped and overwritten as palimpsests, their original texts only faintly visible beneath new writings. Our modern knowledge of Regensburg’s exact wording is therefore patchy, reconstructed from later collections and citations. But the very fact that later councils and theologians quoted Regensburg’s condemnation is itself a testament to the manuscript tradition that carried its voice forward.

The act of copying was also an act of allegiance. When a monastery chose to include Regensburg’s canons in its library, it signaled acceptance of their authority. In this way, the physical distribution of manuscripts mapped onto the spread of doctrinal consensus. A region that lacked such texts might remain hazy about the council’s specifics; one that possessed and studied them could align more tightly with the Carolingian orthodoxy they expressed.

In the margins and interlinear glosses, we sometimes catch glimpses of doubt, curiosity, or pastoral concern. A monk annotating a passage against Adoptionism might jot down a brief explanation in the vernacular, to help less Latinate readers grasp its meaning. Another might cross-reference similar condemnations elsewhere, stitching together a web of texts that, taken together, narrated the Church’s relentless defense of Christ’s full sonship.

Centuries later, humanist scholars and early modern historians would open these same codices, now old and brittle, and find within them evidence of the theological labor of a bygone age. Their works, in turn, ensured that the council of regensburg 792 would not disappear entirely into oblivion, but live on in footnotes, monographs, and, eventually, digital editions. In this sense, the council’s true building was not only the hall in Bavaria where bishops gathered, but the vast, scattered library of Christendom, in which its words found enduring, if fragile, shelter.

Legacy of the Council of Regensburg 792 in Medieval Thought

As the centuries unfolded, the name “Regensburg 792” rarely occupied center stage in theological debates. Greater councils, such as those of Nicaea, Chalcedon, or the Fourth Lateran Council, loomed larger in the collective imagination of Western Christendom. Yet the decisions made at the council of regensburg 792 subtly informed the way medieval thinkers approached Christology for generations.

First, the firm rejection of Adoptionism helped close off certain speculative avenues. While medieval theologians engaged in complex discussions about the communicatio idiomatum—the communication of properties between Christ’s divine and human natures—and about his knowledge, will, and growth in wisdom, they generally did so within tightly controlled boundaries. The idea that Christ’s humanity could be described as “adopted” remained off limits, a red line drawn in the eighth century and rarely, if ever, crossed with any seriousness thereafter.

Second, the controversy sharpened the West’s sensitivity to the language used about Christ’s person. Later scholastics like Anselm, Peter Lombard, and Thomas Aquinas built on a tradition already wary of phrases that might imply a divided subject in Christ. When Aquinas, in the thirteenth century, insisted that there is only one suppositum in Christ—the person of the Word—he did so echoing assumptions that councils like Regensburg had helped solidify. Adoptionism served, retrospectively, as a negative foil: an example of what happened when theologians strayed too near the precipice of dual subjectivity.

Third, the council’s alignment with broader Carolingian efforts at reform contributed to the long-term association between doctrinal clarity and ecclesiastical renewal. Later reform movements, from the Gregorian papacy to the twelfth-century renaissance, could look back on the Carolingian age as an era when kings and bishops worked in concert to purify belief and practice. Regensburg’s anti-adoptionist stance became one thread in this nostalgic tapestry, a reminder that correcting errors about Christ had always been central to authentic reform.

Finally, the condemnation of Adoptionism influenced how medieval Christians regarded the relationship between Christ and the baptized. The insistence that Christ’s sonship is unique—by nature, not by adoption—heightened the sense that believers’ own adopted status was a sheer gift. The liturgy’s language of divine filiation, especially in Easter and Pentecost texts, resonated with an underlying conviction: we are sons and daughters in the Son, not parallel adoptees alongside him. This subtle but important distinction shaped medieval spirituality, coloring prayers about grace, predestination, and the hope of glory.

Modern scholarship, too, has taken an interest in the council. Historians such as Roger Collins and John C. Cavadini have examined the Adoptionist controversy to illuminate the interplay of politics, pastoral care, and doctrinal development in the early medieval West. They show how councils like Regensburg reveal not only what people believed, but how and why they policed belief in the ways they did. As one historian has observed, “The Carolingian reaction to Adoptionism demonstrates the extent to which theological debate had become an instrument of cultural integration in the eighth century”—a judgment that captures both the intellectual and social significance of events in 792.

Regensburg in the Long View: Empire, Faith, and Fragility

Today, Regensburg is a city of picturesque streets and church spires, its medieval core remarkably well preserved. Tourists walk along the stone bridge over the Danube, visit the Gothic cathedral, and sit at cafés where once, long ago, royal envoys and monks might have traded news of distant synods. Few of these visitors think of the summer of 792, when the city hosted a council that helped shape the contours of Western Christianity’s understanding of Christ.

Yet if we look beneath the cobblestones, imaginatively peeling back the layers of time, we can sense the fragility of what the council attempted. The unity it sought to protect—unity of faith, language, and imperial loyalty—would, over the centuries, be tested repeatedly. The Carolingian Empire itself fractured not long after Charlemagne’s death, splitting into rival kingdoms that would eventually form the backbone of modern European states. New controversies arose: the Filioque clause in the creed, the Eucharistic debates of the eleventh century, the Christological reflections of scholasticism.

And yet, through all these changes, the basic anti-adoptionist stance of Regensburg held. No major Latin theologian seriously reopened the question of whether Christ’s humanity might be called “adopted.” The council’s line became part of the deep grammar of Western Christology, so taken for granted that few even remembered the controversy which had necessitated it. This is, perhaps, the final irony of such councils: their greatest successes are often invisible, their decisions woven so tightly into the fabric of thought that later generations forget there was ever an alternative.

The long view also invites humility. The bishops at the council of regensburg 792 acted with conviction, but not with omniscience. They made choices, drew lines, and attached the weighty label of “heresy” to certain ways of speaking about Christ. Their decisions helped safeguard a coherent vision of the Incarnation, but they also closed off other possible avenues of reflection. Modern theologians and historians sometimes wonder whether, amid the necessary defense of core truths, the Church might also have lost something of the rich diversity of early Christian attempts to articulate the mystery of Jesus.

Still, when we listen to the voices of Regensburg—not only its canons, but the prayers and anxieties that surrounded them—we encounter a community deeply aware of its own vulnerability. Surrounded by pagan and Muslim powers, haunted by memories of past heresies, and struggling to form a coherent Christian culture from disparate tribes and languages, they clung to Christ’s identity as the fixed star by which to navigate. To them, the difference between an “eternal Son made flesh” and an “adopted man elevated by God” was not a footnote; it was the difference between a solid anchor and a rope that might snap in the storm.

In that sense, the council of regensburg 792 speaks across the centuries to any age grappling with the tension between doctrinal fidelity and interpretive creativity, between the need for unity and the reality of plurality. It reminds us that theology is never merely abstract; it is bound up with empires and exiles, with fear and hope, with human faces and fragile parchments. And it urges us to listen carefully when the Church gathers, in any era, to ask again the ancient, trembling question: “Who do you say that I am?”

Conclusion

The council of regensburg 792 stands, in the end, as a small but pivotal chapter in the long story of how Western Christianity learned to speak about Christ with both daring and restraint. In a Bavarian city far from the theological giants of the early Church, bishops and abbots wrestled with words that had first been forged in Greek on the shores of the Mediterranean, testing them against new formulas born in the contested lands of Iberia. Their verdict was clear: any suggestion that Christ’s humanity could be described as “adopted” by God threatened the unity of his person and the integrity of the Incarnation.

Behind that verdict lay a web of motives: sincere devotion to the mystery of Jesus, pastoral concern for ordinary believers, and the political ambitions of an emperor determined to weld his expanding realm into a coherent Christian empire. Charlemagne’s invisible hand guided, but did not wholly determine, the outcome; the bishops of Regensburg brought their own memories, fears, and hopes to the council chamber. Together, they produced a decision that would echo through subsequent councils, theological treatises, and the everyday catechesis of parish life.

Their work reminds us that doctrine does not fall from heaven in polished formulas. It is argued, prayed over, copied into manuscripts, and tested in the rough world of empires and borderlands. The adoptionist controversy, with its human protagonists—Elipandus, Felix, Alcuin—reveals how close the line can be between bold reflection and condemned error. And yet, in the judgment of both contemporaries and most later Christians, Regensburg’s defense of Christ’s unqualified sonship helped secure a truth at the heart of the gospel: that the one who walked the dusty roads of Galilee was none other than the eternal Son of God made flesh.

Today, when we read the creeds or hear the gospel proclaimed, we do so within a framework that councils like Regensburg helped to shape. Their decisions have faded into the background, but their effects remain in the way Christians instinctively speak of Jesus—as true God and true man, the only-begotten Son in whose unique filiation we are, by grace, made children of the Father. Remembering the council of regensburg 792 is, therefore, not an antiquarian exercise. It is an act of gratitude and reflection on how fragile communities, in turbulent times, sought to be faithful to a mystery that still surpasses our understanding, yet continues to claim our allegiance and our love.

FAQs

• What was the main issue addressed at the Council of Regensburg 792?
  The council of regensburg 792 primarily addressed the theological doctrine known as Adoptionism, which claimed that Christ, in his humanity, could be called an “adopted” son of God. The bishops judged that this language threatened the Church’s confession of Christ as the eternal Son who became man and therefore condemned the adoptionist formulas as contrary to Scripture and tradition.
• Who were the key figures involved in the Adoptionist controversy?
  The most significant proponents of Adoptionism were Elipandus, archbishop of Toledo, and Felix, bishop of Urgell. On the opposing side, major figures included Charlemagne, who pushed for doctrinal unity, and the scholar Alcuin of York, whose theological writings and letters played a crucial role in shaping the anti-adoptionist response that influenced the council of regensburg 792 and later synods.
• Why did Charlemagne care so much about this theological dispute?
  Charlemagne viewed correct doctrine as essential for both the spiritual health of his subjects and the political unity of his expanding empire. A clear, orthodox confession of Christ helped bind together diverse peoples under a single Christian identity. The emperor feared that tolerating teachings like Adoptionism could fragment belief, weaken imperial cohesion, and even provoke divine displeasure, making the controversy addressed at Regensburg a matter of statecraft as well as faith.
• Did the Council of Regensburg 792 act alone in condemning Adoptionism?
  No. The council of regensburg 792 was one among several Carolingian-era councils that dealt with Adoptionism. Its decisions were echoed and reinforced by later synods, notably the Council of Frankfurt in 794. Together, these gatherings created a strong, empire-wide consensus against adoptionist language and ensured that the doctrine would be marginalized in the Latin West.
• How did the decisions at Regensburg affect ordinary Christians?
  Most laypeople never heard of the council by name, but its decisions filtered into their lives through preaching, catechesis, and liturgy. Priests were instructed to present Christ unequivocally as the eternal Son made man, avoiding adoptionist terms. Over time, this helped shape popular piety and the way ordinary believers imagined Jesus—as uniquely Son by nature, into whose sonship they themselves were adopted through baptism and grace.
• What sources tell us about the Council of Regensburg 792 today?
  Our knowledge of the council comes from surviving conciliar collections, later references in Carolingian documents, and the writings of contemporaries like Alcuin. Many original manuscripts have been lost or exist only in fragmentary form, but enough material remains—often preserved in monastic libraries—to reconstruct the council’s basic decisions and place it within the broader anti-adoptionist campaign of the late eighth century.
• Is Adoptionism still considered a heresy in Christian theology?
  Yes. Within mainstream Catholic, Orthodox, and most Protestant traditions, the idea that Christ is an adopted son of God, in any ontological sense, is rejected. The councils and theological developments that followed events like the council of regensburg 792 firmly established that Christ’s sonship is eternal and by nature, and that believers participate in this sonship only by grace and adoption.
