The Patriarch and the Caliph: How Išōʿyahb III Rewrote Christian Power in the Age of Islam
By the middle of the seventh century, the world of late antiquity had collapsed into something unrecognizable. Empires that had defined history for centuries—the Sasanian and the Roman—lay shattered, their borders erased by the whirlwind conquests of the Muslim Arabs. In 652, a date that marked not just a military defeat but a civilizational transformation, the Sasanian Empire breathed its last, and with it, the old order of Persian Christianity. The world that emerged was ruled by new masters, Arabs who spoke of God’s unity and justice, and who had subdued the two mightiest empires on earth within a single generation.
These conquests brought with them not only swords but ideas—new forms of governance, new economic systems, and a new religious vocabulary. For the Christian communities of Mesopotamia and Persia, the question was no longer how to resist, but how to endure. Among those who faced this challenge head-on was the Patriarch of the Church of the East, Išōʿyahb III (649–659), a figure who would become the architect of Christian survival in the first Islamic century.
Born around 590 to a Persian Christian nobleman named Bastomag, Išōʿyahb entered the Monastery of Beth ʿAbē, a renowned center of learning belonging to the Nestorian tradition. His brilliance was such that he rose rapidly through the ranks of the Church: bishop of Nineveh by 628, metropolitan of Ḥidyāb by 640, and finally, patriarch (catholicos) of the Church of the East in 649. He ruled for roughly a decade, dying in 659, after steering his community through the greatest political and religious upheaval in centuries.
The collapse of the Sasanian monarchy had left the Church exposed. Once protected—if not always favored—by Persian rulers, the Nestorians now faced the uncertain mercy of a new and foreign power. The Muslim Arabs, who had defeated both Persia and Rome, now governed a mosaic of faiths, languages, and ethnicities. The Church of the East, already fractured by rivalries with the Jacobites and internal schisms in Fars and Arabia, suddenly found itself operating within a new imperial order that neither shared its theology nor spoke its language.
It was in this crucible that Išōʿyahb III began to write. His surviving letters—106 in total—preserved in the tenth-century manuscript Vat. Syr. 157 in the Vatican Library—are not mere ecclesiastical correspondence. They are blueprints of adaptation, dispatches from a man who recognized that the preservation of the Church depended not on defiance, but on diplomacy. In them, he urges bishops to remain loyal, to reconcile internal divisions, and above all, to cooperate with the new Arab rulers, whom he increasingly portrayed as instruments of divine will rather than agents of chaos.
At first, his tone is cautious, even resistant. The Arabs were, to his early mind, an unpredictable force—nomads who had overturned the world order. But as their rule consolidated, Išōʿyahb’s letters evolve. He begins to speak of the Muslims as chosen by God to humble the proud and purify the corrupt, a “scourge of correction” rather than a curse. By the end of his correspondence, he writes with an almost prophetic calm, describing cooperation with Muslim authorities as not merely pragmatic but righteous—a path of preservation sanctified by divine providence.
This transformation is the first great Christian reinterpretation of Islam, a theological reordering of the world that would echo through centuries of coexistence. Išōʿyahb’s letters mark the moment when Christianity ceased to be a religion of empire and became, instead, a faith of endurance under empire. They record, in real time, the process by which the Church of the East negotiated its place within the Ummah, not as an enemy to be extinguished, but as a community to be tolerated—and even, at times, respected.
And yet, this was no capitulation. Išōʿyahb was no apologist for conquest. He was, rather, a statesman in robes—a patriarch who understood that to survive was to submit wisely, not to surrender completely. His theology of accommodation was born not of fear, but of realism; not of servitude, but of stewardship. In the ruins of empire, he found a way to reimagine Christian authority in a world now ruled by the Caliph instead of the Shah.
This blog post will explore the world of Išōʿyahb III—his letters, his vision, and his genius for survival. It will trace how a man formed in the courtly Christianity of Persia learned to speak the language of the conquerors without betraying his faith, how he redefined the relationship between Church and State, and how his correspondence laid the groundwork for a century of coexistence before the formalization of the dhimma.
Above all, it will argue that Išōʿyahb III’s story is not one of submission, but of transformation—a portrait of a Christian world learning to live under Islam, and of a patriarch who turned defeat into endurance, and endurance into wisdom.
This is the story of a patriarch who faced the Caliph—and did not break.

⚔️ I. Between Empires and Empires No More (640–650 CE)
By the middle of the seventh century, the ancient order of the Middle East lay in ruins. The twin pillars of late antiquity — Rome and Persia — had bled each other to exhaustion through decades of war. In the chaos that followed, a new, unheralded power emerged from Arabia, a confederation of believers who in less than a generation would remake the map of the known world.
As Christian Sahner writes, “In the opening decades of the seventh century, the Middle East experienced a religious and political revolution. In less than thirty years, the Muslim community evolved from a fragile, persecuted sect into a true world power.” What began as a small movement in Mecca, driven by the conviction of a single Prophet, became a force capable of humbling emperors. By 652 CE, the Sasanian Empire — once the peer of Rome — had collapsed entirely. Xusro II’s dynasty was dead, his capital of Ctesiphon emptied, his heirs scattered. The Romans, though still breathing, had lost Syria, Palestine, and Egypt, their “long peace” of Christendom shattered.
From the ashes of these empires arose a new political and spiritual order. The early caliphs — Abū Bakr, ʿUmar ibn al-Khaṭṭāb, ʿUthmān ibn ʿAffān, and ʿAlī ibn Abī Ṭālib — ruled between 632 and 661 CE, precisely the lifetime of Patriarch Išōʿyahb III (649–659). The parallel is extraordinary: as the Prophet’s Companions governed the nascent Muslim Ummah, Išōʿyahb governed a wounded but resilient Church in Mesopotamia. Both men — the Caliph and the Patriarch — were heirs to collapsing worlds, forced to build new ones upon their ruins.
The Persian heartlands where Išōʿyahb lived had been ravaged by war, plague, and dynastic murder. Between 628 and 632, no fewer than nine kings occupied the Sasanian throne in frantic succession. When the Arabs arrived, they encountered a fractured nobility and a weary population — not hostile, but hollowed out. As Fanny Bessard observes, “The Sasanian Empire was considerably weakened after the Roman–Persian wars and the dynastic crisis of 628–32. Following the decisive Battle of al-Qādisiyya in 637…the whole of the rich Iraqi alluvium, including Khuzistan, passed under Muslim control between 635 and 642.”
It was in these very years that Išōʿyahb, then bishop of Nineveh and later metropolitan of Ḥidyāb (modern Erbil), watched the world around him shift beyond recognition. He witnessed the Battle of al-Qādisiyya (637) and the fall of Ctesiphon, the evacuation of Persian elites, and the slow, almost surreal arrival of new Arab governors who ruled not through fire, but through treaty. The shock was immense — and yet, there was no apocalypse.
Unlike the conquests of old, these Arabs did not exterminate or forcibly convert. As Sahner reminds us, “When it came to the conquered territories, the Muslims generally did not coerce their subjects to convert to Islam…The Qurʾān itself preached against forced conversion, including in the verse, ‘There is no coercion in matters of religion’ (Q 2:256).” The early conquerors saw themselves as a divinely sanctioned elite, entitled to rule but not compelled to erase. They lived off jizya and kharāj — taxes and tribute — not mass conversions.
Archaeology now confirms what the texts whisper: the conquest of the Near East was swift, but not savage. Bessard describes how in Syria and Iraq, resistance was sporadic, and many cities surrendered without battle. “The inhabitants were offered freedom of worship and safety of their churches and crosses,” she notes, citing the treaty of Ludd in Palestine. Even in Antioch, Aleppo, and Qinnasrīn, the transition was so seamless that modern historians have called these campaigns “the invisible conquests.” The mosque of ʿUmar in Bostra, built amid Roman colonnades, did not destroy the old city — it was woven into it, using spolia from pagan temples without tearing down Christian ones.
“Islam’s advocacy of tolerance of the People of the Book,” Bessard writes, “was immensely appealing to minorities continuously persecuted by Roman imperial authorities.” For Jacobites and Nestorians, long divided and often repressed by Constantinople and Ctesiphon alike, the coming of the Arabs was not liberation, but reprieve — the replacement of theological tyranny with administrative pragmatism.
Thus, the world of Išōʿyahb III was not one of extermination, but of transformation. The cities of the Sawād, from al-Ḥira to Mosul, fell under Muslim control, yet their churches still rang, their monks still traded, and their bishops still corresponded. Išōʿyahb’s own letters — written from monasteries and sees under new Muslim rule — make no mention of persecution. Instead, they speak of internal schisms, rival patriarchs, and rebellious metropolitans — signs that the Church’s greatest danger came not from the conquerors, but from itself.
In this fragile peace, Išōʿyahb discerned something divine. The Arabs, though unlettered and foreign, ruled with a justice alien to the late imperial world. They taxed, but they did not torment; they conquered, but they did not compel. Their governance, in his eyes, bore the mark of providence, not perdition.
It was the end of the empires — and yet not the end of the Church.
📜 II. Letters from the Conquered: Išōʿyahb’s Early Correspondence (640–649 CE)
This post examines the earliest Christian theological response to Islam, written not from the safety of Constantinople or Rome, but from the heart of the newly conquered Persian Empire. As Bishop (and later Metropolitan) of Nineveh, Išōʿyahb III was an eyewitness to the rise of the Caliphate. His letters from this period (Ep. 1B–52B; 1M–32M, per Bcheiry/Teule) reveal a sophisticated and evolving strategy for survival, portraying the Muslim conquest as a divine instrument and laying the groundwork for a new Christian identity under Islamic rule.

Section II.I. 🕳️ The "Disciplining Scourge": First Impressions (c. 637-640 CE)
In the immediate aftermath of the conquest, Išōʿyahb’s language is that of a theologian interpreting a catastrophic political event. The Arabs are not yet "Muslims" in his theological framework; they are a divine chastisement.

📨 Letter 39B (c. 638 CE) - To Patriarch Išōʿyahb II
This is a foundational text. Išōʿyahb describes the turmoil, linking it to biblical prophecy and the "end of the end of the world."
The Actors:
"Barbarian governors" 👉 The initial Arab military administrators in the Mosul/Nineveh region.
"Heretics" 👉 The Miaphysite Jacobites, whom Išōʿyahb claims are bribing the new rulers.
The Divine Framework: He states these rulers were "appointed [over us] because of our sins." This is crucial. They are not a demonic force but a "disciplining scourge" – a tool of God's punishment and pedagogy, much like the Assyrians or Babylonians in the Old Testament.
The Turning Point: A "divine miracle" occurs (which Išōʿyahb frustratingly doesn't describe). This miracle causes the Arab rulers to become "embarrassed" by the Jacobites and slowly shift their support towards Išōʿyahb's Church of the East. This shows him that the new rulers are pragmatic and can be persuaded by displays of divine power.
🎯 Key Argument: This letter is likely the first Christian description of Islam from within conquered territory, written during the lifetime of the Prophet's Companions who led these very conquests.

📨 Letter 44B (c. 638 CE) - To Metropolitan Gabriel of Beth Garmay
Here, we see Išōʿyahb as a political operator. He is furious that the Jacobites have used bribes ("golden persuasion") to build a church right by the city gate.
The Strategy: Išōʿyahb decides he must travel to Tikrīt to plead his case directly before the rulers. This reveals several things:
Tikrīt is a key administrative center.
Išōʿyahb believes the Arabs are open to rational (and charismatic) persuasion.
He notes that some of the Arabs' "evil helpers" were formerly Jacobites but are "now counted among the current rulers." This is a tantalizing reference to early conversions to Islam from formerly Christian Arab tribes (like Taghlib), as noted by al-Ṭabarī.

📨 Letter 48B (c. 638/9 CE) - The First Glimpse of Common Ground
This is a theological bombshell. Išōʿyahb chastises monks for being lazy in opposing the Jacobites, telling them they cannot use the "Ṭayayē" (Arabs) as an excuse.
The Key Passage: "For the Ṭayayē Mhaggrē do not assist those who say suffering and death came upon God, the Lord of all."
Terminology:
Ṭayayē: The common neutral term for "Arabs."
Mhaggrē: 👉 A transliteration of the Arabic Muhājirūn (Emigrants). This is a precise, early technical term picked up from official Muslim documents, proving direct contact.
Theological Bridge: For the first time, Išōʿyahb identifies a positive point of doctrinal agreement with the new rulers. Both the Church of the East and the Muslims reject the idea that God Himself could suffer and die (a Christological position they attributed to the Jacobites). The Arabs, he argues, are instinctively repelled by this.

Section II.II 🕊️ From Scourge to Sovereign: A New Church-State Relationship (c. 645-649 CE)
After becoming Metropolitan of Ḥidyāb under Caliph Uthman, Išōʿyahb's tone shifts from describing a punishment to building a partnership.

The Re-Centering of Power
📨 Letters 9M, 14M, 18M, 20M: Išōʿyahb repeatedly emphasizes that the Patriarch has returned to Seleucia-Ctesiphon and is "prospering." He himself travels there to meet with both the Patriarch and the "governor of all."
🔄 The Shift: The old Sasanian capital is re-established as the center of both ecclesiastical and political power. Išōʿyahb is no longer just a bishop complaining to his Patriarch; he is a metropolitan actively negotiating with the new Caliphal administration, likely under Governor al-Walīd b. ʿUqba in Kufa.

⚔️ The Unlikely Alliance: Christians, Muslims, and the Zoroastrian Backlash
While Išōʿyahb is remembered for his relationship with Islam, his letters from 649-652 reveal a more immediate and violent threat: a wave of persecution and church destruction at the hands of Zoroastrian Persians. This was not a random pogrom, but a targeted retaliation born from the collapsing Sasanian Empire's fury against Christians, who were widely perceived as having sided with the Arab invaders.
🔥 The Church Destruction in Fars and Kirmān
In his letter to Metropolitan Šem‘ūn of Fars, Išōʿyahb delivers a devastating report on the fate of the church in the Persian heartlands.
📜 Išōʿyahb's Lament (Letter 14C): "Where are the sanctuaries of Kirmān and of all Fars? They did not last until the uprooting by the coming of Satan, and not even until the command of the kings of the earth... This occurred only because of a simple sign by the command of the [Persian] governor that all the churches in your Fars should be totally uprooted."
The key here is the perpetrator: "the command of the [Persian] governor." The destruction was a deliberate act of state-sponsored retaliation by the last holdouts of the Sasanian regime. Išōʿyahb mocks the Zoroastrians as a "contemptable Demon," but the reality for the Christians in Fars was brutal and total.
🎯 The "Fifth Column" Accusation: Why the Zoroastrians Struck
The Zoroastrian persecution was not arbitrary. It was a logical response to the shifting allegiances of the 7th-century Middle East.
Shared Monotheism: For Zoroastrians, the theological line between the strict monotheism of Christians and Muslims was blurry. Both rejected the dualism and fire worship central to Zoroastrianism. In the eyes of the Persian authorities, Christians and Muslims were two branches of the same "Abrahamic" threat.
Rapid Christian Collaboration: As Iskandar notes, after the Muslim victories, "many Arab Christian tribes and local Christian people made peace with the Muslim Arabs." This was seen by the Sasanian loyalists as a betrayal. Christians were not just a conquered people; they were turncoats and a fifth column, actively collaborating with the invaders against the ancient Persian state.
The Geopolitical Reality: The Zoroastrians were fighting a two-front war: a military front against the advancing Muslim armies, and an internal, ideological front against a large Christian population they no longer trusted. Destroying churches was a way to punish collaboration and reassert control in territories slipping from their grasp.
💪 Išōʿyahb's Response: Forge the Alliance
Confronted with this existential threat from the Zoroastrians, Išōʿyahb's pro-Arab policy shifted from a strategy of convenience to one of necessity. He saw the Muslim rulers not just as tolerable overlords, but as essential protectors.
This is perfectly illustrated in his letter to Bishop Jacob of Šahrazūr (Letter 7C), where the bishop is being harassed by Zoroastrians and begs Išōʿyahb to use his Arab connections for help.
Išōʿyahb's response is stunning. He does not sympathetically promise to call in a favor from the Muslim governor. Instead, he delivers a fierce rebuke, calling the Zoroastrians an "extinct authority" and commanding Bishop Jacob to stop being a coward and to "stand actively and act strongly" to suppress the Zoroastrian uprising himself.
📜 Išōʿyahb's Command (Letter 7C): "Move yourself, O blessed man, with the zeal of God-fearing... remove the idol far from its worshipers. Do not be afraid of a place where there is no idol. But stand actively and act strongly... and immediately the dead will be silenced in the tomb of their vanity."
Išōʿyahb is not telling the bishop to seek Muslim help. He is telling him that he and his Christian community are now the local enforcers of the new Islamic order. They are to act with the confidence and authority that comes from having the Caliphate at their back.
🤝 The "God-Fearing" Coalition
This context explains Išōʿyahb's masterstroke: the adoption of the term "God-Fearers" (Dahlaw d'Alaha) to describe both Christians and Muslims.
By using this term, Išōʿyahb was constructing a powerful religio-political identity that explicitly excluded the Zoroastrians. He was building a theological framework for the military reality on the ground:
| The "God-Fearing" Coalition (Christians & Muslims) | The "Idol-Worshipping" Enemy (Zoroastrians) |
|---|---|
| Shared Belief: One Almighty God who does not suffer. | False Belief: Dualistic divinity (Ahura Mazda vs. Angra Mainyu). |
| Shared Identity: "People of the Book" / Monotheists. | "Pagan" Identity: Fire worshippers, idolaters. |
| Political Reality: Allies under the new Caliphal order. | Political Reality: The defeated "extinct authority" of the old Persian order. |
This was a brilliant piece of ideological engineering. It gave Christians a dignified and theologically elevated place within the new Islamic empire, not as mere subjects, but as partners in a shared, divine project of monotheistic triumph.
🧩 Conclusion: The True Threat Was Behind Them
For Išōʿyahb and the Church of the East in the 650s, the Muslim Arab was the future—a future to be negotiated, influenced, and collaborated with. The Zoroastrian Persian, however, was the past—a past of persecution, political subjugation, and theological hostility that was now lashing out in its death throes.
🕵️♂️ Identifying the Men of the Caliphate: The Muslim Officials in Išōʿyahb's Letters
While Išōʿyahb rarely names specific Muslim officials—referring to them by titles like "governors," "the governor of all," or "rulers"—we can triangulate their identities by combining his chronological data with the detailed conquest narratives from Arab historians like al-Baladhuri. This allows us to move from vague titles to specific historical actors, the Companions of the Prophet and early generals who shaped his world.
The table below synthesizes this information, identifying the most likely individuals Išōʿyahb would have encountered.
Išōʿyahb's Reference & Letter (Date) Location & Context Likely Muslim Official(s) Historical Identification & Role "Barbarian governors" / "Rulers"
📨 Letters 39B, 44B, 48B (c. 637-640) Nineveh & Mosul Region
Initial conquest, conflict with Jacobites, "divine miracle." 1. ‘Utba b. Farqad al-Sulami
2. Local Garrison Commanders 👉 ‘Utba was explicitly appointed by Caliph Umar in 20 AH/641 CE as the governor of Mosul, which administered Nineveh. Al-Baladhuri states he conquered the eastern fortress by force and made peace for the western side. He was the senior official in the region during Išōʿyahb's early episcopacy.
👉 The local commanders Išōʿyahb dealt with daily would have been subordinates of ‘Utba, implementing his policies and collecting taxes. "Governors" / "Rulers in Tikrīt"
📨 Letter 44B (c. 638) Tikrīt
Išōʿyahb travels here to plead his case before a higher authority against the Jacobites. Military Governor of Tikrīt (under ‘Utba b. Farqad) 👉 Al-Baladhuri confirms that ‘Utba b. Farqad also conquered Tikrīt. The official Išōʿyahb met was likely the garrison commander or fiscal agent (‘āmil) left in charge of this strategically important city. "Governor of all"
📨 Letter 46B (c. 638) Nineveh Region
Išōʿyahb seeks a mediator with connections to the top authority to free a captured Christian leader. ‘Iyāḍ b. Ghanam 👉 The "governor of all" strongly implies the overall commander for the region. This referring of course to ‘Iyāḍ b. Ghanam, who al-Baladhuri credits with the overall conquest of Al-Jazira (Mesopotamia). ‘Iyāḍ's campaign (launched 18 AH/639 CE) overlapped with this period, and his authority would have superseded ‘Utba's. "Mhaggrē" (Muhājirūn)
📨 Letter 48B (c. 638/9) Nineveh Region
Theological argument about God's nature. The Arab Military Class 👉 This is not a specific person but a collective term for the Muslim conquerors. Using the technical term Muhājirūn shows Išōʿyahb's awareness of their self-identity as "Emigrants" for the faith. He is engaging with their ideological claims. "The Ruler" / "Governor of all"
📨 Letter 18M (c. 648) Seleucia-Ctesiphon & Kufa
As Metropolitan, Išōʿyahb travels to the capital to negotiate with both the Patriarch and the secular authority. Al-Walīd b. ‘Uqba
(Governor of Kufa, 646-650 CE) 👉 This is a highly confident identification. By c. 648, the entire region of Iraq, including Išōʿyahb's see of Ḥidyāb, was administered from Kufa. Al-Walīd b. ‘Uqba was Uthman's governor there. Išōʿyahb's reference to traveling to clarify matters "about which the ruler wrote to me" perfectly describes a metropolitan's interaction with the Caliphal governor. The Unnamed Authority
📨 Letter 7C (c. 649/50) Šahrazūr
Bishop Jacob hopes Išōʿyahb will intercede with the Arabs against Zoroastrians. Al-Walīd b. ‘Uqba or his Sub-Governor in Mosul 👉 As Patriarch, Išōʿyahb's direct relationship would be with the top governor, al-Walīd b. ‘Uqba. The administrative chain for Šahrazūr ran through Mosul, which was by this time a subordinate province to Kufa. The "authority" Bishop Jacob feared was the local enforcement power of this Kufan administration.
While Išōʿyahb rarely names specific Muslim officials—referring to them by titles like "governors," "the governor of all," or "rulers"—we can triangulate their identities by combining his chronological data with the detailed conquest narratives from Arab historians like al-Baladhuri. This allows us to move from vague titles to specific historical actors, the Companions of the Prophet and early generals who shaped his world.
The table below synthesizes this information, identifying the most likely individuals Išōʿyahb would have encountered.
| Išōʿyahb's Reference & Letter (Date) | Location & Context | Likely Muslim Official(s) | Historical Identification & Role |
|---|---|---|---|
| "Barbarian governors" / "Rulers" 📨 Letters 39B, 44B, 48B (c. 637-640) | Nineveh & Mosul Region Initial conquest, conflict with Jacobites, "divine miracle." | 1. ‘Utba b. Farqad al-Sulami 2. Local Garrison Commanders | 👉 ‘Utba was explicitly appointed by Caliph Umar in 20 AH/641 CE as the governor of Mosul, which administered Nineveh. Al-Baladhuri states he conquered the eastern fortress by force and made peace for the western side. He was the senior official in the region during Išōʿyahb's early episcopacy. 👉 The local commanders Išōʿyahb dealt with daily would have been subordinates of ‘Utba, implementing his policies and collecting taxes. |
| "Governors" / "Rulers in Tikrīt" 📨 Letter 44B (c. 638) | Tikrīt Išōʿyahb travels here to plead his case before a higher authority against the Jacobites. | Military Governor of Tikrīt (under ‘Utba b. Farqad) | 👉 Al-Baladhuri confirms that ‘Utba b. Farqad also conquered Tikrīt. The official Išōʿyahb met was likely the garrison commander or fiscal agent (‘āmil) left in charge of this strategically important city. |
| "Governor of all" 📨 Letter 46B (c. 638) | Nineveh Region Išōʿyahb seeks a mediator with connections to the top authority to free a captured Christian leader. | ‘Iyāḍ b. Ghanam | 👉 The "governor of all" strongly implies the overall commander for the region. This referring of course to ‘Iyāḍ b. Ghanam, who al-Baladhuri credits with the overall conquest of Al-Jazira (Mesopotamia). ‘Iyāḍ's campaign (launched 18 AH/639 CE) overlapped with this period, and his authority would have superseded ‘Utba's. |
| "Mhaggrē" (Muhājirūn) 📨 Letter 48B (c. 638/9) | Nineveh Region Theological argument about God's nature. | The Arab Military Class | 👉 This is not a specific person but a collective term for the Muslim conquerors. Using the technical term Muhājirūn shows Išōʿyahb's awareness of their self-identity as "Emigrants" for the faith. He is engaging with their ideological claims. |
| "The Ruler" / "Governor of all" 📨 Letter 18M (c. 648) | Seleucia-Ctesiphon & Kufa As Metropolitan, Išōʿyahb travels to the capital to negotiate with both the Patriarch and the secular authority. | Al-Walīd b. ‘Uqba (Governor of Kufa, 646-650 CE) | 👉 This is a highly confident identification. By c. 648, the entire region of Iraq, including Išōʿyahb's see of Ḥidyāb, was administered from Kufa. Al-Walīd b. ‘Uqba was Uthman's governor there. Išōʿyahb's reference to traveling to clarify matters "about which the ruler wrote to me" perfectly describes a metropolitan's interaction with the Caliphal governor. |
| The Unnamed Authority 📨 Letter 7C (c. 649/50) | Šahrazūr Bishop Jacob hopes Išōʿyahb will intercede with the Arabs against Zoroastrians. | Al-Walīd b. ‘Uqba or his Sub-Governor in Mosul | 👉 As Patriarch, Išōʿyahb's direct relationship would be with the top governor, al-Walīd b. ‘Uqba. The administrative chain for Šahrazūr ran through Mosul, which was by this time a subordinate province to Kufa. The "authority" Bishop Jacob feared was the local enforcement power of this Kufan administration. |
🧩 Synthesis: The Evolving Chain of Command
The identities of these officials reveal the consolidation of Muslim power
Phase 1 (c. 637-640): Military Governorship. Išōʿyahb's earliest contacts were with conquering generals like ‘Utba b. Farqad and ‘Iyāḍ b. Ghanam. Their rule was direct, military, and focused on pacification and treaty-making. His terms for them ("barbarians," "scourge") reflect the raw, violent nature of this initial contact.
Phase 2 (c. 645-650): Integrated Civil Administration. A decade after the conquest, the state had bureaucratized. Išōʿyahb, now a metropolitan and then patriarch, deals with the formal Caliphal Governor in Kufa, al-Walīd b. ‘Uqba. Their relationship is characterized by negotiation, travel to the capital, and written correspondence. Išōʿyahb's shift in tone to a "peaceful and flourishing time" corresponds directly with this more stable, bureaucratic phase of rule under Uthman.
Conclusion: Išōʿyahb III did not live in a vague "time of the Arabs." He navigated a specific, evolving administrative hierarchy. His theological response—from interpreting them as a divine scourge to negotiating with them as legitimate sovereigns—was shaped by his personal and institutional interactions with these very men: the Companions and governors of the Rashidun Caliphate.:

As Catholicos-Patriarch, Išōʿyahb III’s primary mission crystallized: to preserve the unity and orthodoxy of the Church of the East under the new, permanent reality of Islamic rule. The early, tentative observations of the bishop and the confident negotiations of the metropolitan now gave way to a comprehensive strategy. This was not merely about survival; it was about building a symbiotic relationship with the Caliphate to secure the Church's future. This project, however, faced its greatest challenge not from the Muslim rulers, but from within—from a schism in the wealthy and independent-minded ecclesiastical province of Fars. The resulting crisis forced Išōʿyahb to justify his pro-Arab policy in the starkest terms, revealing a profound recalibration of Christian power in a post-Persian world.
🗺️ III.I The Schism in the South: A Church Divided Against Itself
The most severe threat to Išōʿyahb's patriarchate emerged from "the southern part of the world"—the vast ecclesiastical province of Fars, which included Beth Qaṭrayē (Eastern Arabia), Mazūn (Oman), and India. This region had a long history of autonomy from the central authority in Seleucia-Ctesiphon.
A History of Independence
The Church in Fars traced its roots to the Apostle Thomas and often acted as a rival center of power.
Metropolitan Yazdad of Fars rejected the Synod of Babay in 497.
In 585, Gregory of Fars refused to attend the Synod of Išōʿyahb I.
They had even struck the name of the unpopular Patriarch Joseph (552–567) from their liturgical books.
By Išōʿyahb III's election, the province was de facto independent. The crisis erupted over two key issues:
The Sale of Sacraments: Metropolitan Šem‘ūn of Fars was imposing heavy financial fees on candidates for the bishopric and priesthood in India. Išōʿyahb, in Letter 14C (c. 650), delivers a scorching rebuke, framing this simony as a spiritual catastrophe.
Open Rebellion: When Išōʿyahb and the synod sent delegations to Fars and East Arabia to restore order around 651/652, the local bishops refused to receive them. They held their own council and, crucially, sought the support of the local civil authorities to legitimize their autonomy.
📜 Išōʿyahb's Rebuke (Letter 14C): "When you locked the door of episcopal consecration in the face of the many peoples of India, and took away the gift of God for the sake of perishable gains... those who are above us locked the door of the Lord’s gift in the face of your needs... the world is now filled with bishops, priests, and the faithful... [but] your province... dwells now in darkness."
This was more than a disciplinary matter; it was a direct challenge to the patriarch's authority. Išōʿyahb's response was swift and severe: he excommunicated the rebellious bishops.
The Political Masterstroke: Appealing to the Faithful
Facing a schism supported by local rulers, Išōʿyahb executed a brilliant political maneuver. He bypassed the rebellious bishops entirely and appealed directly to the lay notables and civil administrators in East Arabia. In Letter 18C (c. 652), he writes to the powerful "faithful people into whose hands is placed the authority of administration" in key centers like Dayrīn, Mašmahīg, and Hagar.
🎯 His Instruction: "Choose and send to us those rebellious bishops, if you think they are still fit to repair their priestly service; or choose and send to us others who you think are more qualified... so that they be anointed, sanctified, and perfected. Then they will be sent to you again... according to the law of Christ."
This was revolutionary. Išōʿyahb was empowering the lay elite—who operated within the new Islamic administrative system—to effectively overthrow their own schismatic bishops and re-establish communion with the Patriarch. This strategy reveals his core insight: in the new order, the Church's stability depended on an alliance with its own integrated, powerful laity, who in turn were connected to the Caliphal power structure.
⚔️ III.II The Choice: Collaboration with Islam or Annihilation by Zoroastrianism
The schism in the South coincided with a violent backlash from the remnants of the old Sasanian order. This provided Išōʿyahb with the perfect historical object lesson to justify his entire policy.
The Zoroastrian Retaliation in Fars and Kirmān
While the Church in the North (Mesopotamia) was enjoying a "peaceful and flourishing time of faith" under the Arabs, the provinces of Fars and Kirmān became the last bastions of Persian resistance. Here, the Zoroastrian authorities, realizing the Christians had shifted their allegiance to the Arabs, launched a brutal persecution.
In the same Letter 14C where he rebukes Šem‘ūn for simony, Išōʿyahb contrasts the situation in the North with the catastrophe in the South:
📜 The Lesson of the Ruined Churches: "Where are the sanctuaries of Kirmān and of all Fars? They did not last until the uprooting by the coming of Satan, and not even until the command of the kings of the earth... This occurred only because of a simple sign by the command of the [Persian] governor that all the churches in your Fars should be totally uprooted."
The message was devastatingly clear. The rebellious South, which sought to operate independently of the Patriarch's pro-Arab policy, had not gained freedom—it had faced total annihilation at the hands of the "extinct" Persian power.
The Implicit Argument
Išōʿyahb masterfully frames the two possible futures for his Church:
| The Path of the Schismatics (Fars) | The Path of the Patriarch (Mesopotamia) |
|---|---|
| Alignment with the old Persian power. | 🔷 Alignment with the new Arab power. |
| ❌ Result: Churches uprooted, persecution, "darkness." | ✅ Result: "Peaceful and flourishing time of faith," stability, growth. |
This was not an abstract theological choice; it was a pragmatic, geopolitical one. The Muslims, whom he now confidently called "God-fearers," were not just the lesser of two evils—they were the guarantors of the Church's very existence and prosperity. The persecution in Fars proved, beyond any doubt, that the future of Eastern Christianity lay in a collaborative relationship with the Islamic Caliphate. The schismatics weren't just disobedient; they were leading their people to physical and spiritual ruin.
This crisis cemented the foundation of Išōʿyahb's legacy. He was no longer just a negotiator; he was the architect of a new paradigm for Christian power in a Muslim world.
☀️ III.III The Case of Mazūn: A Choice, Not a Sword
While Išōʿyahb battled schism in Fars and persecution in Kirmān, a different and, in many ways, more revealing crisis unfolded in Mazūn (Oman). This was not a story of churches being destroyed, but of a mass apostasy that exposed the very mechanics of the early Islamic social contract. The events in Mazūn, occurring in the heartland of the Caliphate under Caliph Uthman, provide our clearest window into the pragmatic and often surprisingly flexible policies of the first Muslim rulers.
💰 The Apostasy: A Financial Decision, Not a Persecuted One
Išōʿyahb’s account is startlingly clear: the Christians of Mazūn abandoned their faith without facing violence, fire, or the sword.
📜 Išōʿyahb's Lament (Letter 14C): "Where are the great people of Mazūn—Those who did not see any sword and [experienced] neither fire nor suffering, but merely because of their love for the portion of their possession were trapped like fools, so that the hell of apostasy swallowed them up and they were lost forever."
The patriarch explicitly states that the Muslim authorities did not force conversion. Instead, they presented a choice, one rooted in the fiscal structure of the early Islamic state:
📜 The Terms of the Choice: "The people of Mazūn... themselves admit that the Arabs have not forced them to abandon their faith, but only asked them to give up a portion of their possession and [thus] keep their faith. Yet they abandoned their faith, which is eternal, and retained the portion of their possession, which lasts for a short time."
This "portion of their possession" is the Jizya, the poll tax on non-Muslims. The Islamic offer was simple: remain Christian and pay the tax, or convert to Islam and be exempt. For the wealthy Christian community of Mazūn, their faith had a price, and they chose their wealth.
🏛️ The Stark Contrast: Išōʿyahb’s Portrait of Early Islamic Rule
Išōʿyahb is furious at his flock for their choice, but his letters simultaneously provide a powerful, firsthand testimonial to the character of early Muslim rule. He goes out of his way to praise the Arabs, creating a stark contrast between their just governance and the Zoroastrian persecution.
📜 A Stunning Endorsement (Letter 14C): "As for the Arabs, to whom God has now given rule over the world, and who are among us, as you know: not only do they not oppose Christianity, but they praise our faith, honor our priests and the holy men of Our Lord, and give aid to the churches and monasteries."
This is not the language of a man describing oppressive theocrats. He describes a regime that is:
Tolerant: They "do not oppose Christianity."
Respectful: They "praise our faith, honor our priests."
Supportive: They "give aid to the churches and monasteries."
This description, coming from the highest Christian authority within the Caliphate, fundamentally challenges the anachronistic image of a uniformly rigid and persecutory early Islam.
🧩 Synthesis: The Three Futures of Christianity under Islam
By 652 CE, Išōʿyahb III could look across his patriarchate and see three distinct models of Christian existence under Islamic rule, which he used as object lessons to justify his entire policy.
| Case Study | The Schismatic South (Fars) | The Apostate South (Mazūn) | The Loyalist Center (Mesopotamia) |
|---|---|---|---|
| Political Alignment | Sought independence; allied with fading Persian power. | Integrated into Caliphate; faced the choice of the Jizya. | Išōʿyahb's policy: Full collaboration with Arab rulers. |
| Outcome for Church | ❌ CATASTROPHE Churches uprooted by Zoroastrians; total destruction. | 🤝 PRAGMATIC FAILURE Mass apostasy to avoid tax; community lost by choice. | ✅ SUCCESS & STABILITY "Peaceful & flourishing time of faith"; churches aided. |
| Išōʿyahb's Lesson | Resistance to the new order leads to physical annihilation. | Valuing wealth over faith leads to spiritual death. | Collaboration with the "God-fearing" Arabs ensures survival and prosperity. |
🎯 The Refutation of Later Mythmaking
The case of Mazūn, specifically, serves as a powerful historical corrective:
It Refutes the "Pact of Umar" as a 7th-Century Reality: The so-called "Pact of Umar," which lays out strict and humiliating conditions for Dhimmis, is a later document, likely from the 8th or 9th century. The reality in the 640s-650s, as seen in Mazūn, was far more pragmatic. The choice was financial integration (Jizya) versus religious integration (Conversion), not one of systematic social humiliation.
It Refutes the Idea of Intolerant Companions: The rulers in Oman were the governors of Caliph Uthman, a Companion of the Prophet leading an administration of Companions. Their policy was not one of forced conversion or rigid theocracy, but of practical state-building. They needed revenue and social cohesion. Offering a financial incentive for conversion was a pragmatic tool, not an ideological crusade.
It Shows a Theologian Grappling with a New World: Išōʿyahb’s anguish is not that of a man whose people are being martyred, but of a shepherd whose flock is voluntarily leaving for worldly gain. His problem is not Islamic intolerance, but Christian complacency. This flips the traditional narrative of early Christian-Muslim relations on its head.
Conclusion: The tragedy of Mazūn was, for Išōʿyahb, the ultimate validation of his strategy. It proved that the Caliphate was a stable, rational power that kept its word. The threat to the Church was not Muslim persecution, but the moral failure of Christians who were unwilling to pay the price—literally—for their faith. In response, Išōʿyahb doubled down on his alliance with the Caliphate, positioning the Church of the East as a loyal partner to the Islamic state, the only viable path to ensure that the fate of Mesopotamia would not become the fate of Fars or Mazūn.
🏛️ III.IV The Secular Arbiter: Why Christians Sought Justice from the Caliph
The most audacious move in the schism came when the bishops of Fars and Beth Qaṭrayē, led by Metropolitan Šem‘ūn, decided to bypass the Patriarch entirely. They took their case for ecclesiastical independence directly to the highest secular authority: the Muslim Arab rulers. Išōʿyahb reports with fury that they "brought [their] rebellious request before the door of the rulers of the time." He even specifies that they appealed to the "Great Ruler, the chief of the rulers of this time," a title that can only refer to Caliph Uthman ibn Affan (r. 644–656) in Medina.
This act—Christians traveling to the heart of the Islamic world to have a church dispute settled—seems counterintuitive. But it was a calculated move that reveals the sophisticated and pragmatic nature of the early Caliphate.
🧠 Why the Schismatics Went to Medina
The rebel bishops were not naive. They appealed to the Caliph for several compelling reasons that align perfectly with the realities of the 7th-century Caliphate:
The Caliph as the Guarantor of Order: The primary role of the early Caliph was to maintain peace, collect taxes, and ensure stability (fitna) within the burgeoning empire. A schism within a major dhimmi community like the Church of the East was a source of social unrest and administrative confusion. The bishops likely argued that recognizing their autocephalous (self-governing) church in the South would simplify administration and create a more stable, localized power structure, making it easier for the Caliphate to govern.
Precedent from Other Traditions: The Sasanian Empire had a long history of state intervention in the affairs of the Church of the East, often confirming patriarchs and even intervening in doctrinal disputes. The bishops of Fars were simply adapting an old Persian model to the new Arab rulers. They were treating the Caliph as a new "King of Kings," the ultimate arbiter of communal leadership.
The Power of the Purse: The Christian communities of Fars and Beth Qaṭrayē were wealthy, involved in the lucrative Indian Ocean trade and pearl fishing. By appealing directly to the fiscal authorities, the schismatics could potentially negotiate their Jizya payments as a separate entity, cutting out the patriarchal center in Seleucia-Ctesiphon. This would have been financially appealing to both the local churches and the Caliphal treasury.
Exploiting Tribal Connections: The Christians of Beth Qaṭrayē (Eastern Arabia) had long-standing relationships with Arab tribes, some of whom were now powerful within the Islamic state. They leveraged these connections to gain access and present their case, believing their local influence could sway the decision in Medina.
⚖️ The Caliph's Court: A Realm of Law, Not Theology
Crucially, the schismatics were not asking Caliph Uthman to rule on the theological merits of their case. They were asking for a political and administrative ruling: to be recognized as a separate, legally autonomous dhimmi community.
This is where Išōʿyahb’s own description of the early Islamic state is so revealing. The Caliphate, in its first decades, functioned less as a theocracy and more as a pragmatic, legalistic empire. Its concern was not the internal doctrines of Christianity, but the maintenance of a clear, hierarchical system of authority that ensured the smooth flow of taxes and social peace.
Išōʿyahb himself articulates this principle perfectly, explaining the proper relationship between Christians and the state:
📜 Išōʿyahb's Political Philosophy (Letter 18C): "They are commanded by us to give what ought to be given to any authority, such as the poll taxes to whom they are due, the duties to whom they are due, reverence to whom it is due, respect to whom it is due... While they diligently submit themselves to all authorities outside the Church in flesh, soul, possessions, properties, and in all matters, they refuse to submit to Christianity."
This is a stunningly clear description of the Dhimmi contract as it initially functioned. It was a reciprocal, legal agreement, not a one-sided tool of humiliation.
❌ The Verdict and Its Meaning
According to Išōʿyahb, the schismatics' gambit failed spectacularly. He states that they "have in reality been despised by the governors just as their rebellion deserved."
Why did they fail?
The Value of a Single Interlocutor: For the Caliphal administration, dealing with one unified Patriarch for the entire Church of the East was far more efficient than managing multiple, squabbling Christian authorities. Upholding Išōʿyahb’s central authority preserved a clear chain of command.
Išōʿyahb’s Superior Diplomacy: The Patriarch had spent years building a reliable, collaborative relationship with the Arab governors in Mesopotamia. He was a known quantity who could guarantee the stability and tax revenue of his community. The schismatics from the periphery were an unknown risk.
The Rejection of "Fitna": The schismatics' actions were rebellion, just as Išōʿyahb said. The early Islamic state had a deep-seated aversion to internal disorder (fitna). By siding with the established patriarchal hierarchy, Caliph Uthman’s administration was upholding order and condemning sedition.
🧩 Conclusion: The Refutation of the "Pact of Umar" Myth
This entire episode serves as a powerful refutation of the later, rigid image of Islamic rule embodied by the so-called "Pact of Umar."
| The Reality (c. 650 CE) | The Later Myth ("Pact of Umar") |
|---|---|
| The Caliph as Arbiter: Christians actively seek the Caliph's judgment on internal leadership disputes, viewing him as a source of legitimate secular authority. | The Caliph as Imposer: The ruler unilaterally imposes strict, humiliating conditions on passive, subjugated dhimmis. |
| A Legal-Fiscal Contract: The relationship is defined by reciprocal obligations: taxes in exchange for protection and autonomy. Išōʿyahb frames this as a righteous duty. | A Tool of Humiliation: The Dhimmi status is primarily designed to enforce social inferiority and religious segregation. |
| Pragmatic, Not Theocratic: The state's concern is administrative efficiency and social order, not theological purity or the suppression of other faiths. | Ideologically Driven: The state's policy is an extension of Islamic theology, aimed at manifesting the dominance of Islam. |
The schismatic bishops' journey to Medina proves that the earliest Islamic state was seen by its subjects—even Christian ones—as a competent, accessible, and legitimate imperial authority. They went to the Caliph for the same reason anyone appeals to a supreme court: they believed he had the power to grant them justice. The fact that Išōʿyahb could simultaneously praise the Arabs for their support of churches and condemn his own bishops for appealing to those same rulers reveals a world of nuance that later polemics, both Christian and Muslim, would work hard to erase. In the 650s, the relationship was not yet one of pure domination and submission, but of negotiation and integration under a new, powerful, and surprisingly pragmatic sovereign.
⛪ III.V The Reclamation: How Išōʿyahb Brought the South to Heel
Faced with a full-blown schism supported by local rulers and even appealing to the Caliph himself, Išōʿyahb III could not rely on secular force. Instead, he executed a masterful campaign of ideological and spiritual reclamation, leveraging his central authority, a powerful theological argument, and the very real threat of divine impotence to bring the rebellious South back into the patriarchal fold.
🏛️ The Strategy of Centralization: Patriarchy, Synod, and Capital
Išōʿyahb’s first move was to reassert the unassailable authority of the central Church institutions. He framed the schismatics not just as disobedient, but as having placed themselves outside the only legitimate structure of Christian life.
The Unbroken Chain of Authority: In his letters, he constantly emphasizes the holy triad of his power: the Patriarch, the Synod, and the See of Seleucia-Ctesiphon. He declares that the Holy Synod, convoked in the traditional capital, has ratified the excommunication of the rebels, making their separation official and their priesthood null.
📜 Letter 16C: "Therefore, the Church of God, through the Holy Synod which was convoked at this time in the city of the catholicate seat, decided in your case what you have already decided for yourselves: that you will be estranged from the honor of the order [of the priesthood] that you are known by."
By focusing on the geographical and historical centrality of Seleucia-Ctesiphon, Išōʿyahb reminded the entire Church that there was still a single, functioning center of orthodoxy and power, even after the fall of the Sasanian Empire. He made unity synonymous with the ancient capital itself.
✝️ The Theological Masterstroke: The Argument of a "Powerless Priesthood"
This was Išōʿyahb's most brilliant and devastating weapon. He argued that by cutting themselves off from the apostolic succession flowing from the Patriarch, the schismatic bishops of Fars had not just broken a rule—they had severed their own connection to divine power.
The "Source of Life": Išōʿyahb uses the powerful metaphor of a river flowing from a source. The true power of the priesthood (the source) flows from Christ, to the Apostles, to the Patriarch, and down through the canonical hierarchy. The schismatics, by their rebellion, had dammed this river.
They Have the Title, But Not the Power: He concedes that the rebel bishops have the title of bishop, but they lack the actual power of the priesthood. This power is what enables true miracles, exorcisms, and the zealous faith that defends the Church in times of crisis.
📜 Letter 14C: "If the consecration is done illegally, the power of priesthood will not be transmitted from above to below... they would steal only the name while the power [of priesthood] will not go along with the name."
Explaining the Catastrophes: This argument allowed Išōʿyahb to brilliantly explain the twin disasters in the South:
The Ruin in Fars: Why were the churches destroyed without a fight? Because the illegitimate clergy of Fars lacked the spiritual power to inspire zeal or work miracles that would have defended their community or shamed the Zoroastrian persecutors. They were, in his words, "humble, quiet, and tranquil" in the face of their own destruction—a sign of divine abandonment.
The Apostasy in Mazūn: Why did the Christians of Mazūn apostatize over a simple tax? Because their church, cut off from the true source of grace, was spiritually weak. They lacked the "proofs of faith" (miracles, exorcisms, holy conduct) that would have given them the strength to choose faith over wealth.
This framed the schism not as a political disagreement, but as a soteriological crisis. To be outside the Patriarch's communion was to be cut off from the grace necessary for salvation and for earthly survival.
🛡️ The Carrot: The Promise of Spiritual Power
Against this bleak picture, Išōʿyahb offered a compelling path back: reconciliation. He framed his call for the rebels to return as an offer to restore them to the source of divine power.
📜 Letter 16C: "I called you to come to me, i.e., to the Church of God. You were called to be given the gift of the Spirit so that you would be completed in it, in order to stand against the fire of the blasphemy that raged in your region."*
He contrasted the vibrant, miracle-filled Christianity of his own territories—where "the glory of Christianity is shining"—with the spiritual desolation of the schismatic South. The choice was clear: remain in rebellious darkness or return to the light and power of the one, true Church.
🤝 The Muslims' Role in Išōʿyahb's Victory
Crucially, the Muslim administration played a silent but decisive role in Išōʿyahb's victory, exactly as he had anticipated.
The Caliph's Verdict: As previously covered, when the schismatics appealed to Caliph Uthman, they were rebuffed. The Caliphal state, valuing order and a single point of contact, upheld Išōʿyahb’s central authority. This secular rejection stripped the schismatics of any legal or political legitimacy.
The Proof of the Policy: Išōʿyahb’s entire strategy was predicated on the idea that collaboration with the Muslims ensured stability and prosperity. The schismatics provided the perfect negative example. Their territories (Fars and Mazūn) were the ones suffering catastrophe (persecution and apostasy), while Išōʿyahb's loyal territories in Mesopotamia were, by his own account, enjoying a "peaceful and flourishing time." The Muslims, by simply being the stable, predictable power that Išōʿyahb said they were, validated his entire policy.
🧩 Synthesis: The Final Triumph of a Realist
Išōʿyahb III did not reconquer the South with armies, but with a superior argument and a more compelling offer. He successfully:
Politically Isolated the Schismatics by ensuring the Caliphal state recognized only him.
Theologically Disarmed Them by arguing their priesthood was powerless and their sacraments were invalid.
Pragmatically Outmaneuvered Them by demonstrating that his collaborative model with Islam worked, while their independence led to ruin.
The restoration of the South to the Patriarchate was the ultimate validation of Išōʿyahb’s lifelong project. He proved that in the new world of Islam, the Church’s power would not be found in nostalgic dreams of Persian patronage or in schismatic independence, but in a disciplined, unified hierarchy that could negotiate from a position of strength with the Caliphate. By the end of the crisis, he had not just quashed a rebellion; he had cemented a new paradigm for Eastern Christianity: a Church that could thrive under Muslim rule by being doctrinally pure, centrally organized, and politically astute.
🏛️ Conclusion: The Patriarch's Tapestry—Weaving a Christian Future under Islamic Rule
The evolution of Išōʿyahb III's attitude toward the Muslim Arabs is not merely a personal journey; it is the story of the Church of the East strategically adapting to one of the most seismic political shifts in history. From the first shock of conquest to the calm assurance of a settled patriarch, his perspective evolved in three distinct, pragmatic stages, culminating in a comprehensive vision for Christian survival and even prosperity.
🔄 The Three Stages of Išōʿyahb
Stage & Timeline Portrayal of Muslim Arabs Core Strategy & Justification I. The Bishop (c. 637-640)
Early Conquest "Barbarian Scourge"
A divine punishment, a "disciplining scourge" for Christian sins. Survival & Persuasion: Prove theological superiority over Jacobites through miracles and apologetics to win the rulers' favor. II. The Metropolitan (c. 645-649)
Consolidation of Caliphate → Legitimate Sovereigns
God's qualified rulers for a new era; partners in administration. Collaboration & Integration: Re-center the Church in Seleucia-Ctesiphon, negotiate directly with Arab governors, and ensure stability. III. The Patriarch (c. 650-659)
Crisis in the South "God-Fearing" Allies
Monotheistic partners in a divine plan to overthrow Zoroastrianism and unify the faithful. Symbiosis & Justification: Frame Muslims and Christians as allied "God-Fearers"; blame internal Christian failure for apostasy, not Muslim rule.

🧠 The Master Narrative: A Theology of Pragmatism
Išōʿyahb’s ultimate success lay in his ability to construct a powerful, theologically-grounded narrative that explained the new reality and guided his flock's response.
A Divine Mandate: He consistently taught that the Muslim conquest was not a random catastrophe but a deliberate act of God. He stripped the event of its demonic character and framed it within a biblical paradigm of divine chastisement and historical change.
The "God-Fearing" Alliance: His most brilliant rhetorical move was to adopt the term "God-Fearers" (Dahlaw d'Alaha). This placed Christians and Muslims into a shared religio-political category of monotheists, united against the "idol-worshipping" Zoroastrians of the fallen Persian Empire. He wasn't just making peace with Islam; he was ideologically aligning with it against a common enemy.
The Scapegoat of Schism: When his policy faced its greatest test with the mass apostasy in Mazūn, he did not blame the Muslims. Instead, he turned inward. He argued that the schismatic, simoniacal churches of the South had severed themselves from the true source of grace flowing from his patriarchate. Their resulting "powerless priesthood" left their flocks spiritually weak and vulnerable, leading them to abandon their faith for worldly gain. The problem was not Islamic pressure, but Christian faithlessness.
📜 The Historical Bombshell: Refuting the "Companion Myth"
Išōʿyahb’s testimony is devastating to later, anachronistic narratives about early Islam. He lived and wrote during the rule of Caliph Uthman, a Companion of the Prophet, in a state administered by the very men who knew Muhammad and compiled the Quran. And what does he describe?
Not Theocratic Tyrants, but Pragmatic Rulers: The Muslim officials are open to persuasion, impressed by miracles, and primarily concerned with administrative efficiency and tax collection.
Not Forced Conversion, but a Fiscal Choice: In Mazūn, the offer was clear: pay the Jizya and keep your faith, or convert and be exempt. This was a policy of integration, not inquisition.
Not Religious Persecution, but Patronage: Išōʿyahb explicitly states the Arabs "praise our faith, honor our priests and the holy men of Our Lord, and give aid to the churches and monasteries." This is not the behavior of rigid theocrats intent on subjugating all other faiths.
The so-called "Pact of Umar," with its rigid and humiliating restrictions, reflects a later, more legally formalized stage of the Islamic state. Išōʿyahb shows us the earlier, more fluid reality, where the relationship was being negotiated in real-time by pragmatic conquerors and a shrewd Christian leader.
🎯 Final Conclusion: The Architect of a New Era
Išōʿyahb III was far more than a passive observer. He was the architect of a new paradigm for Christian existence in the Islamic world. He successfully:
Transformed a theological crisis into a political opportunity.
Centralized his Church's authority by leveraging the Caliphate's preference for a single interlocutor.
Provided a compelling theological framework that allowed his flock to accept Muslim rule not as a defeat, but as part of a divine plan.
He proved that the path to power for a "dhimmi" church lay not in resistance or nostalgia, but in doctrinal unity, hierarchical discipline, and strategic collaboration with the new sovereigns. In doing so, he secured the future of the Church of the East for centuries, crafting a model of coexistence that was, in its earliest days, far more nuanced and mutually beneficial than later history would often remember.
🕌 IV. The Era of the Companions (640–659 CE): Tolerance Before Theory
The entire ecclesiastical career of Išōʿyahb III—from his first troubled letters as Bishop of Nineveh to his confident reign as Patriarch—unfolds under the rule of the Rashidun Caliphs: ʿUmar ibn al-Khattab, ʿUthmān ibn ʿAffān, and ʿAlī ibn Abī Ṭālib. These were not distant, legendary figures; they were the contemporaries whose policies directly shaped his world. They were the Companions of the Prophet Muhammad, the men who knew the Revelation by heart and had fought at its dawn. If a rigid, theocratic intolerance were ever to manifest in Islam, it would have been here, in this age of conquest and zeal.
Yet, Išōʿyahb’s letters reveal a startlingly different reality: an era defined not by systematic persecution, but by a rough-and-ready justice and a pragmatic pluralism.
📜 The Evidence from the Ground: A Church Not Crushed, But Negotiating
The portrait that emerges from Išōʿyahb's correspondence is one of a functioning Christian society under Muslim rule.
Retention of Autonomy: Christians retained their bishops, their internal hierarchies, and their ecclesiastical courts. Išōʿyahb’s entire struggle with the schism in Fars presupposes a Church that still managed its own affairs, excommunicated its own bishops, and organized its own synods.
Churches and Monasteries Intact: In his loyal territories, Išōʿyahb reports that the Arabs "give aid to the churches and monasteries." This is not the description of a state intent on the humiliation or destruction of other faiths.
Dialogue, Not Diktat: Išōʿyahb does not describe receiving orders; he describes negotiating. He travels to Tikrīt and Seleucia-Ctesiphon to persuade governors. He wins them over through theological common ground and displays of divine power. The relationship is transactional and diplomatic, not merely one of submission.
🤝 The Spirit of the Early Treaties: Protection, Not Humiliation
This on-the-ground reality is perfectly reflected in the earliest capitulation treaties, which emphasize the preservation of life, property, and worship. The famous treaties of ʿUmar with Jerusalem, Ḥīra, and others guaranteed the safety of churches and the freedom of Christian worship in exchange for the payment of the Jizya.
This spirit is not a later invention; it is rooted in the Quranic worldview that the earliest Muslims were building. The revelations they carried with them contained a divine mandate to protect the places of worship of other "People of the Book."
📖 Qurʾān 22:40: "[They are] those who have been evicted from their homes without right—only because they say, 'Our Lord is Allah.' And were it not that Allah checks the people, some by means of others, there would have been demolished monasteries, churches, synagogues, and mosques in which the name of Allah is much mentioned. And Allah will surely support those who support Him."
As the classical exegete al-Ṭabarī explains in his Tafsīr, this verse was understood by the earliest authorities to mean that God prevents the oppression of the powerful against the weak, thereby protecting the "monasteries of the monks" (ṣawāmiʿ al-ruhbān) and the "churches of the Christians" (biyaʿ al-naṣārā) from destruction. The divine purpose is to allow worship to continue in all these houses of God.
Furthermore, the Quran explicitly commanded a baseline of justice and kindness toward non-hostile non-Muslims.
📖 Qurʾān 60:8-9: "Allah does not forbid you from those who do not fight you because of religion and do not expel you from your homes - from being righteous toward them and acting justly toward them. Indeed, Allah loves those who act justly. Allah only forbids you from those who fight you because of religion and expel you from your homes and aid in your expulsion - [forbids] that you make allies of them. And whoever makes allies of them, then it is those who are the wrongdoers."
Al-Ṭabarī's commentary clarifies that this initially applied to maintaining family ties with peaceful polytheists in Mecca, but its principle of just and kind treatment was understood by scholars to extend to any non-belligerent people.
⚖️ The Moral of the Story: Justice Over Legalism
The era of the Companions, often labeled "primitive," was in fact the most tolerant phase of the Caliphate. The evidence is clear:
No forced conversions were state policy.
No systematic destruction of churches occurred.
No humiliating "Pact of Umar" yet existed.
Instead, there was a "rough justice that the patriarch himself could respect." Išōʿyahb could condemn the apostasy in Mazūn not as a failure of Muslim policy, but as a failure of Christian character, precisely because the choice offered was a fiscal one, not made at sword-point. He could praise the Muslim rulers for supporting his churches because they were, by and large, upholding the Quranic injunction to protect them.
If intrinsic, ideological intolerance had been the driving force of early Islam, it would have reached its zenith in the hearts and policies of the Prophet's own Companions. Yet, under their rule, a Christian patriarch could negotiate, thrive, and even call them "God-fearing" allies. The later, more rigid legalism of the "Pact of Umar" was a development of a more settled, complex, and perhaps more insecure empire. The earliest days, by contrast, were characterized by a confident, pragmatic, and surprisingly just imperial vision—one that Išōʿyahb III, a master of realpolitik, recognized, respected, and successfully leveraged to ensure the survival of his Church for centuries to come.
🧩 V. The Historical Irony: The Pragmatic Caliphate vs. The Legalistic "Pact"
The letters of Išōʿyahb III present a stunning historical reality: for the first century of Islam, under the very rule of the Prophet's Companions, there was no "Pact of Umar," no codified system of dhimma, and no systematic program of humiliation. The relationship was governed by ad hoc treaties, pragmatic negotiation, and a spirit of coexistence. The so-called "Pact of Umar" was not the foundation of early Muslim-Christian relations but a later, 8th-9th century retrojection, created to solve problems that did not exist in the immediate aftermath of the conquest.
⚖️ The Two Eras: A Comparative Table
The world Išōʿyahb describes and the world later jurists invented are fundamentally different. The following table contrasts the reality of the 7th century with the legal theory of the 9th.
| Aspect | The Era of the Companions (c. 640-680 CE) As Witnessed by Išōʿyahb | The Era of Codification (c. 750-850 CE) As Codified in the "Pact of Umar" |
|---|---|---|
| Governing Principle | Pragmatic Coexistence & 'Ad Hoc' Treaties (Sulh) | Legalistic Subordination & Uniform Code |
| Social Context | Muslims a ruling minority, focused on conquest and administration. Cohabitation was limited. | Muslims a settled majority in many urban centers. Daily friction and visibility of non-Muslim life. |
| Christian Status | Protected Allies ("God-Fearers"). Išōʿyahb negotiates as a peer; churches are aided. | Subjugated Dhimmis. A legally defined inferior class, subject to restrictive clauses. |
| Religious Practice | Freedom within treaties. Išōʿyahb reports no restrictions on church building, processions, or bells. | Heavily Restricted. Bells banned, new churches forbidden, processions curtailed, distinctive clothing imposed. |
| Core Justification | Quranic Principle & Pragmatism: "To you your religion, to me my religion" (Quran 109:6); need for stable rule and taxes. | Theological & Social Hierarchy: To manifest the supremacy of Islam and prevent assimilation of the Muslim majority. |
🔄 The Turning Point: Why Pragmatism Was Lost
According to Levy-Rubin, the shift was not driven by a sudden discovery of intolerant texts, but by profound demographic and social changes within the Caliphate itself.
The Settlement Crisis: Initially, Muslims were a military elite living in garrison cities (amsar like Kufa and Basra). Their contact with the vast non-Muslim population was limited. The early sulh (surrender) treaties, which guaranteed life, property, and worship in exchange for taxes, were sufficient. This is the world Išōʿyahb knew.
The Rise of Cohabitation: Over the 8th century, Muslims ceased to be just conquerors and became settled urbanites. They moved into existing cities like Damascus and Jerusalem, and non-Muslims moved into the amsar. This created a new, intimate cohabitation that the old treaties never anticipated.
The "Insupportable" Situation: For the first time, the Muslim majority was confronted daily with the "offenses" of non-Muslim public life:
🐷 Pigs and wine sold openly in markets.
🔔 Church bells and naqus (semantrons) sounding loudly.
✝️ Public religious processions with crosses and icons filling the streets.
💼 Non-Muslims in high government positions wielding authority over Muslims.
This visible, audible, and olfactory dominance of non-Islamic life in shared urban spaces was, in Levy-Rubin's words, "insupportable for the now-settled conquerors." The old, tolerant treaties became a source of social tension.
⚔️ The Jurists' Dilemma and Their Solution
The early Muslim jurists of the 8th and 9th centuries (like Abu Yusuf, al-Shafi'i, and al-Shaybani) faced a problem: the original sulh treaties were binding, but they were too permissive for the new reality.
Their debate revolved around a key question: What defines a "Muslim city" (misr) where restrictive rules apply?
| School of Thought | Definition of a "Muslim City" (Misr) | Implication for Dhimmis | Key Proponent |
|---|---|---|---|
| The "Tolerant" School | Only cities founded by Muslims (Kufa, Basra) or taken by force ('anwatan). Cities with original sulh treaties kept their terms forever. | Strict adherence to early treaties. Churches in Damascus or Jerusalem were inviolable. Rights were permanent. | Abu Yusuf, al-Shafi'i |
| The "Restrictive" School | Any city with a predominant Muslim population and Islamic governance. Original treaties could be overridden by the new demographic reality. | Rights were conditional. Churches in such cities could be destroyed, dhimmis could be expelled to special quarters. | al-Shaybani, al-Tabari |
The "Pact of Umar" was the ultimate victory of the Restrictive School. It was a brilliant, if cynical, legal solution:
It was framed as a petition from Christians to Caliph Umar, thereby making the restrictive conditions seem voluntary and consensual.
It provided a single, uniform code that could be applied to all dhimmis, effectively annulling the hundreds of more lenient, individual sulh treaties from the conquest era.
It created a legal framework for the social humiliation and segregation that the Muslim urban majority now demanded.
🎯 The Ultimate Conclusion: The Patriarch's Pen vs. The Jurist's Fiction
The historical irony is profound. The most rigid and formalized system of discrimination emerged not during the zealous, militant conquests, but generations later, from the desks of jurists in a settled, sophisticated empire.
The Patriarch’s pen, not the Pact’s fiction, records the true beginning of Muslim–Christian relations. It tells of a generation of believers—Companions of the Prophet—who ruled half the world and yet did not trample the conscience of a single church. Išōʿyahb III did not negotiate with the specter of the Pact of Umar; he treated with the living successors of Muhammad, who honored their word, aided his monasteries, and praised his faith. The later ‘dhimmi system’ was not the prophetic model but a bureaucratic one, born not from the Quran’s core, but from the complex anxieties of an empire learning to live with itself.
The testimony of Išōʿyahb III is therefore not just a historical curiosity; it is a powerful corrective. It proves that the original relationship between Islam and Christianity, as practiced by the founders of the Caliphate, was capable of a justice and a pragmatism that later legal theory would work hard to erase.
🌅 VI. Conclusion — The Legacy of Holy Realism
The world of 652 CE had been shattered and remade. The ancient Persian Empire had crumbled into dust, and the Roman eagle had been driven back beyond the Taurus Mountains. In their place stood a new, unexpected power from the Arabian desert, speaking a new language of faith and wielding a sword that had carved out an empire in a single generation.
Yet, in the ruins of the old order, something remarkable emerged. It was not the darkness of annihilation, but the grey light of a difficult, pragmatic, and ultimately enduring peace. This new reality was not born of sentimental tolerance, but of what can only be called Holy Realism—a clear-eyed acceptance of God's will in history, coupled with a fierce determination to ensure the survival of the faith within it.
Išōʿyahb III stands as the first and greatest architect of this new Christian existence. He was the first theologian of coexistence, a patriarch who looked upon the armies of Islam and saw not only a "disciplining scourge" but also "God-fearing" men with whom one could negotiate, debate, and build a future. He understood that the Church’s power would no longer flow from royal patronage, but from its own internal unity, doctrinal purity, and strategic alliance with the state. He did not just survive the conquest; he mastered its logic.
His Muslim contemporaries, the Companions of the Prophet and their immediate successors, were in turn the first practitioners of a pluralistic justice. They established a rule that was, for its time, stunningly restrained. They offered a choice: integrate through faith or through finance. They upheld treaties, honored churches, and, as Išōʿyahb himself testified, praised the Christian faith they could have so easily crushed. Theirs was a sovereignty confident enough to permit difference.
The letters of Išōʿyahb III are therefore more than a historical archive. They are the earliest and most powerful testimony that the rise of Islam did not extinguish Eastern Christianity. Instead, it disciplined it, refined it, and forced it to find a strength it had forgotten. Stripped of imperial privilege, the Church of the East could no longer rely on the sword of a Christian king. It had to learn once again to live by faith, not by empire.
In the dialogue between this pragmatic patriarch and the pragmatic caliphs, we find a founding model for coexistence—one built not on perfect agreement, but on mutual interest, respect for power, and a shared space under the same sovereign sky. It is a legacy that resonates across centuries: a lesson in how to endure, how to negotiate, and how to keep the faith when the world has been turned upside down.
THE END.
