Christianity in al-Andalus

When St. Laura died in 864, she belonged to a Christian society that had already lived under Muslim rule for a century and a half and would endure, in dwindling form, for several more. The conquest of 711 did not erase the Church of Visigothic Spain: it left the hierarchy standing — a metropolitan at Toledo, bishops at Córdoba, Seville, and other sees, with their councils, churches, and monasteries — and it left intact the old Hispanic (Visigothic) liturgy that the Mozarabs would carry as their most distinctive inheritance. These “Arabized” Christians (musta’rib) kept their faith while their language and culture drifted toward Arabic, a tension that defined the learned world of Eulogius and Paulus Albarus, the writers who give us St. Laura’s milieu. This file supplies that well-documented ecclesial context: the institutional Church, its ancient liturgy, its anxious intellectual life, and its long decline to near-disappearance under the Almoravids and Almohads.

Tradition: Pre-Schism Western (Mozarabic) / Orthodox reception

The Word “Mozarab”

The term Mozarab derives from the Arabic musta’rib, “one who makes himself an Arab” or “Arabized” — applied to the indigenous Christians of al-Andalus who lived under Muslim rule while retaining their Christian faith and, for a time, their Latin and Visigothic church-life, even as they increasingly adopted the Arabic language and the cultural forms of the dominant society (Ann Christys, Christians in al-Andalus, 711–1000, Richmond: Curzon, 2002; “Mozarabs,” Wikipedia, as locator). The word is not a confessional label the Christians chose for themselves so much as a description of their cultural condition, and modern scholarship treats it with some caution, since “Mozarab” can imply a more uniform community than the sources support (Christys, 2002). What the term names accurately is the double bind of these Christians: they were a tolerated, protected, and taxed religious minority — dhimmis — whose distinctness from their rulers was religious and legal, while their daily culture grew steadily more Arabic (on the legal frame see ../05-arrest-and-trial/under-the-dhimma-law.md).

The Church That Survived the Conquest

The decisive fact for understanding St. Laura’s world is that the Visigothic Church was not destroyed in 711 but absorbed into the new order with its structure largely intact. Mozarabic communities kept their own bishops and their own judges, who administered justice according to the Visigothic Liber Iudiciorum, and their bishops continued to meet in synods under the authority of the metropolitan of Toledo (Christys, 2002; “Mozarabs,” Wikipedia, as locator). Churches and monasteries went on functioning; Eulogius of Córdoba, writing in the 850s, names a whole cluster of monastic houses in and around the city (Kenneth Baxter Wolf, Christian Martyrs in Muslim Spain, Cambridge: Cambridge University Press, 1988; on those houses see ../03-the-convent-of-cuteclara/the-mozarabic-womens-houses.md). The Church was even visible enough to generate its own controversies: in eighth-century Toledo the metropolitan Elipandus advanced the Adoptionist view that Christ was the “adoptive son” of the Father — a position condemned in the Frankish realm under Charlemagne — which shows a Mozarabic hierarchy still theologically active and in contact with the wider Latin Church (“Mozarabs,” Wikipedia, as locator).

By St. Laura’s lifetime this institutional Church had to decide how to respond to the martyr movement breaking out in Córdoba from 851 onward — Christians who provoked their own executions by publicly denouncing Muhammad. The hierarchy split. The bishop of Córdoba, Saul, was sympathetic enough that he pressed the reluctant Eulogius back into priestly ministry; but it was the metropolitan Reccafred (Reccafredus) — described in the sources as metropolitan of Seville and Córdoba and as a friend of the Muslim authorities — who took the cautious, conciliatory line. After the martyrdoms of Flora and Maria heightened the crisis, a church council was convened around 852 under the new emir Muhammad I, and Reccafred urged compromise, even imprisoning churchmen (Eulogius among them) who encouraged the martyrs (Wolf, 1988; Jessica A. Coope, The Martyrs of Córdoba, Lincoln: University of Nebraska Press, 1995; “Eulogius of Córdoba,” OrthodoxWiki, as locator). That a metropolitan could summon a council, discipline clergy, and negotiate with the emir at once shows both the survival of the Church’s machinery and the narrow ground on which it operated.

The Mozarabic (Hispanic) Liturgy

The Mozarabs’ most enduring possession was their liturgy. The rite they prayed — known variously as the Mozarabic, Hispanic, or Visigothic Rite — was the ancient liturgy of the Spanish Church, developed above all in the Visigothic period and codified by the great seventh-century fathers of the Spanish Church. It was Isidore of Seville, with Julian and Ildefonsus of Toledo, who shaped this rite as Damasus, Leo, Gelasius, and Gregory shaped the Roman; Isidore presided over the Fourth Council of Toledo (633), which established uniform chant for the Divine Office and the Eucharist across the Spanish sees (“Mozarabic Rite,” Encyclopedia.com; “Mozarabic Rite,” Wikipedia, as locator). To carry this rite was to carry the whole patristic and liturgical inheritance of Visigothic Spain — Isidore’s vast learning, a distinctive proper of texts and chants, its own structure of the Mass and Office — a genuinely independent ancient tradition of the Latin West, parallel to but not derived from Rome.

This is why the Mozarabic Church matters far beyond the borders of al-Andalus: it preserved an entire Western liturgical world that the post-Reconquest Church would otherwise have lost. That preservation came at a cost. After the Christian advance and the capture of Toledo (1085), the Roman Rite was imposed and the old Hispanic Rite suppressed — the Council of Burgos (1080) had already mandated its replacement by the Roman liturgy and Gregorian chant, a policy pressed by the reforming papacy of Gregory VII (“Mozarabic Rite,” Encyclopedia.com; “Mozarabic chant,” Wikipedia, as locator). The rite survived only in a handful of Toledo parishes, and was deliberately rescued at the turn of the sixteenth century by Cardinal Jiménez de Cisneros, who founded the Capilla Mozárabe in Toledo cathedral and had the old books printed so the rite could still be celebrated (Encyclopedia.com; FSSPX News, “The Mozarabic Rite,” as locator). It survives there, and in the Talavera chapel of the old cathedral of Salamanca, to this day — a living relic of the liturgical tradition the Mozarabs had kept alive under Islam.

The World of Eulogius and Albarus

The literary culture of St. Laura’s Córdoba is known chiefly through two friends, Eulogius (d. 859) and the layman Paulus Albarus (Paul Alvarus, c. 800–861), who had studied together under the teacher Speraindeo and remained lifelong intimates (Wolf, 1988; “Paul Albar,” Wikipedia, as locator). Theirs was a deliberately learned Latin Christian culture, increasingly anxious that it was being lost. In his Indiculus Luminosus (854), written to defend the martyrs and to cast Muhammad as a forerunner of Antichrist, Albarus pauses to lament that young Christians prized Arabic poetry and letters over their own scriptures: they could no longer write a decent letter in Latin, he complains, yet composed in classical Arabic more elegantly than the Arabs themselves (“Paul Albar,” Wikipedia, as locator; Kenneth Baxter Wolf, ed. and trans., The Indiculus Luminosus of Paul Alvarus, Liverpool: Liverpool University Press, 2022). The passage is the single most-quoted evidence for Mozarabic Arabization, and it is a complaint — testimony precisely from the party resisting the trend.

Eulogius embodied the counter-effort to keep Latinity alive. Around 848 he traveled north to the Christian kingdoms of the Pyrenees — into Navarre, visiting monasteries such as San Zacarías — and there, beyond the reach of al-Andalus, he found Latin manuscripts that had grown rare in the south. He brought back texts of Augustine, Virgil, Juvenal, and Horace (among others), feeding them into the Córdoban Christian schools as fresh fuel for a culture he feared was dimming (“Eulogius of Córdoba,” Wikipedia and OrthodoxWiki, as locators; Wolf, 1988). The detail captures the whole predicament: a Mozarabic priest had to ride into the Christian north to recover the Latin classics and fathers, because in Córdoba the language of learning was becoming Arabic. Eulogius’s own standing in the Church was high — at his death he was bishop-elect of Toledo, never consecrated because he was executed (11 March 859) for sheltering the convert Leocritia (Wolf, 1988; “Eulogius of Córdoba,” OrthodoxWiki, as locator).

The Long Decline

The Mozarabic community of al-Andalus did not end suddenly; it eroded. Three forces wore it down. The first was conversion to Islam, slow but cumulative across generations, which steadily reduced the Christian share of the population — the process Albarus’s lament reflects from the inside (Christys, 2002; Coope, 1995). The second was emigration north to the expanding Christian kingdoms, a movement of Mozarabic families that ran for centuries during the Reconquest and carried with them their rite and their books (Christys, 2002). The third was direct persecution under the North African dynasties of the eleventh and twelfth centuries. In 1126 the Almoravid emir Ali ibn Yusuf ordered the mass deportation of Andalusi Christians to North Africa, and the Almohads who took power by mid-century were harsher still, pressing Christians and Jews toward conversion, death, or exile and driving a further exodus northward, especially toward Toledo and the Tagus valley (“Expulsion of Andalusi Christians in 1126,” Wikipedia, as locator; “Almohad Caliphate,” Wikipedia, as locator). The outcome is telling: after the Almohad period a Jewish community reappeared in the region, but a native Christian one did not. The Mozarabic Church of al-Andalus had effectively ceased to exist where it had begun, surviving only as a transplanted inheritance — the rite at Toledo, the saints in the calendars, the books carried north.

[Disputed: The pace and extent of conversion to Islam, and thus the size and vitality of the Christian population in St. Laura’s day, are genuinely contested. Richard W. Bulliet’s influential “conversion curve” (Conversion to Islam in the Medieval Period, 1979) inferred from the chronology of Muslim names that the bulk of conversion in al-Andalus came after the ninth century, with Muslims a minority until roughly the tenth — implying a still-substantial Christian majority or near-majority in Laura’s lifetime. Critics, including Alwyn Harrison (“Behind the Curve: Bulliet and Conversion to Islam in al-Andalus Revisited,” Al-Masāq 24, 2012), argue that Bulliet’s data and method do not actually support the standard reading of a robust, slowly declining Christian community, and that conversion may have been faster or the Christian population already more reduced than the curve suggests. The disagreement bears directly on how to read the martyr movement: as the cry of a large community under cultural pressure, or of a shrinking one sensing its own dissolution. This file reports both positions and does not adjudicate between them.]

Tie to the Orthodox Frame

The Mozarabic Church belonged wholly to the undivided, pre-schism Church of the first millennium. Its liturgy was codified in the seventh century, its hierarchy descended from the Visigothic councils, and its life under Islam ran through the ninth century — entirely within the era before the East–West estrangement hardened into schism (conventionally dated to 1054, but a gradual process). From the Orthodox standpoint, then, St. Laura, Eulogius, Albarus, and the martyrs of Córdoba are saints of the one undivided Church, and the Mozarabic Rite is an authentic ancient Western liturgical tradition of that same Church — which is why these Western saints are received and venerated in the Orthodox world (see ../08-veneration/reception-and-the-western-saints.md and, for the broader framework, ../../orthodoxy/11-world-orthodoxy/early-and-byzantine/pre-schism-church.md).
