A Shared Origin
Before there was an Orthodox Ethiopia or a Catholic Ethiopia, there was simply Christian Ethiopia — and it arrived remarkably early. Tradition traces the first seeds of the faith to the Ethiopian eunuch baptized by the deacon Philip in Acts 8, but organized Christianity in the Kingdom of Aksum begins in the fourth century with Saint Frumentius, a shipwrecked Syro-Phoenician who was enslaved at the Aksumite court, rose to influence the young king, and was eventually consecrated the first bishop of Ethiopia by Saint Athanasius of Alexandria. From that consecration onward, the Ethiopian Church looked to the See of Alexandria for its patriarchal oversight, a relationship that would last for roughly sixteen centuries.
For its first several centuries, Christian Ethiopia was simply part of the wider communion of churches in full agreement with one another, sharing bishops, liturgy, and doctrine with Alexandria and the other great sees of the ancient Christian world. The division that eventually produced two distinct Ethiopian churches, one Orthodox and one Catholic, did not originate in Ethiopia at all. It originated at an ecumenical council held far away, on the Bosphorus, in the year 451.
Chalcedon: Where the Split Actually Comes From
The Council of Chalcedon in 451 defined Christ as possessing two natures, fully divine and fully human, united in one person — a formula known as dyophysitism. The Ethiopian Church, along with the Coptic, Syriac, Armenian, and Malankara churches, rejected this formula, holding instead to miaphysitism: the belief that Christ’s divine and human natures are united in a single nature without division, confusion, or change. Rome and Constantinople interpreted this position as the heresy of monophysitism, the belief that Christ’s humanity was absorbed entirely into His divinity, though the Oriental Orthodox churches have long maintained that this characterization misrepresents their actual teaching.
The Ethiopian word for this position, tewahedo, means “made one,” and it gives the Ethiopian Orthodox Church its full name: the Ethiopian Orthodox Tewahedo Church. This theological stance placed Ethiopia, alongside Egypt and the other non-Chalcedonian churches, outside full communion with Rome and Constantinople for the next fifteen centuries, cut off from the councils and creedal statements that would go on to shape Western and Byzantine Christianity. Any Ethiopian Christian community that later accepted Chalcedon and papal primacy, by definition, ceased to be Ethiopian Orthodox in the technical sense and became something else — Ethiopian Catholic.
It is worth being precise about what this means in practice today. The doctrinal line separating the Ethiopian Orthodox Tewahedo Church from the Ethiopian Catholic Church is, formally, the Catholic Church’s acceptance of the fifth-century Council of Chalcedon and, with it, the universal jurisdiction of the pope. Everything else that distinguishes the two churches today — their separate hierarchies, their different biblical canons, their distinct histories after the seventeenth century — flows downstream from this one theological and jurisdictional fork.
The Jesuit Union That Lasted Ten Years
For over a thousand years after Chalcedon, Ethiopia’s Christianity remained essentially untouched by Rome. That changed in the sixteenth century, when Portuguese soldiers arrived to help the Christian Ethiopian kingdom repel invasion from the Adal Sultanate, bringing Jesuit missionaries in their wake. Those missionaries focused their efforts on converting the country’s ruling class rather than the general population, hoping that a converted monarch could bring the entire Ethiopian Church into union with Rome.
The strategy worked, for a time, largely through one remarkable man. Pedro Paez arrived in Ethiopia in 1603, mastered Ge’ez and Amharic, and won the trust of Emperor Susenyos through patience, architectural skill, and genuine personal regard for Ethiopian customs. Susenyos converted to Catholicism under Paez’s influence and declared it the state religion in 1622, the same year Paez himself died. Rome, sensing an extraordinary opportunity, appointed the Portuguese Jesuit Afonso Mendez as Patriarch of Ethiopia the following year.
Mendez did not share his predecessor’s patience. Where Paez had been careful to respect Ethiopian liturgical customs, Mendez pursued a program of thorough latinization, imposing the Latin calendar, Latin liturgical forms, and Latin vestments even in monasteries that had followed the ancient Ethiopian rite for centuries. Susenyos formally submitted the entire Ethiopian court to Roman authority on February 11, 1626, and then, at Mendez’s urging, enacted harsh laws against subjects who refused to conform. The result was open civil war, a conflict that claimed roughly eight thousand lives before Susenyos, exhausted and disillusioned despite his military victory, granted his subjects freedom of religion and effectively abandoned the union.
His son and successor, Fasilides, finished what Susenyos had started reversing. Fasilides restored the Ethiopian Orthodox Church, expelled Mendez and the Jesuits in 1632, closed the mission schools they had built, and cut Ethiopia off from further European religious contact for nearly two centuries — a decision he framed as necessary to protect the country’s sovereignty and cultural cohesion from foreign religious interference. The entire Catholic union, from Susenyos’s declaration in 1622 to the final expulsion in 1632/1636, had lasted roughly a decade. It left a lasting wariness toward Rome that shaped Ethiopian religious policy for generations.
The Modern Ethiopian Catholic Church
The Catholic Church did not return to Ethiopia in force until the nineteenth century, this time through Lazarist and Capuchin missionaries working under the comparatively tolerant reign of Emperor Menelik II. This revival eventually produced a permanent, organized Ethiopian Catholic hierarchy. The Ethiopian Catholic Church, formally established in 1930, is a sui iuris Eastern Catholic church in full communion with the Holy See, using the Alexandrian Rite in the Ge’ez language and accepting both the Christological doctrine of Chalcedon and the pope’s universal jurisdiction.
Its administrative structure has grown gradually over the past century. An apostolic exarchate for Ethiopic-Rite Catholics was established at Addis Ababa in 1951, elevated to a full metropolitan archeparchy in 1961 with suffragan eparchies at Asmara and Adigrat, and reorganized further over the following decades as new eparchies were created and, in 2015, as the Eritrean and Ethiopian Ge’ez Rite churches were formally separated into two distinct sui iuris churches. Today the Ethiopian Catholic Church is composed of the Metropolitan Archeparchy of Addis Abeba and three suffragan eparchies: Adigrat, Emdeber, and Bahir Dar-Dessie.
Leadership recently changed hands. Cardinal Berhaneyesus Demerew Souraphiel, who had led the Ethiopian Catholic Church as Archbishop of Addis Abeba since 1999, retired in June 2026, and Pope Leo XIV appointed Tesfaye Tadesse Gebresilasie, who had been serving as auxiliary bishop of the same see, as the new Metropolitan Archbishop of Addis Abeba and head of the Ethiopian Catholic Church. In terms of size, the contrast with Ethiopian Orthodoxy remains stark: as of recent counts, the Catholic Church in Ethiopia, including both its Ge’ez Rite and Latin Rite jurisdictions, numbers under a million baptized members, representing well under one percent of the national population, in a country where Orthodox and Catholic Christians together with Protestants and Muslims make up a diverse religious landscape.
The Canon: Two Different Bibles
Perhaps the most immediately visible difference between the two churches, for anyone who picks up their respective Bibles, is the sheer size of the canon. The Ethiopian Orthodox Tewahedo Church holds the broadest Old Testament canon in Christianity, traditionally numbered at 81 books. This canon includes texts absent from both the Catholic and Protestant Bibles, most notably the Book of 1 Enoch, the Book of Jubilees, and the three books of Meqabyan — a distinctly Ethiopian set of texts unrelated to the Greek 1–2 Maccabees despite the similar name.
The Ethiopian Catholic Church, by contrast, follows the standard Catholic biblical canon of 73 books, the same canon used by every other Catholic church in the world, Latin or Eastern. This creates a curious situation unique among the world’s Christian traditions: two churches praying the same Ge’ez liturgy, chanting the same ancient hymns, and sharing the same saints for most of their common history, yet reading from Bibles of noticeably different length and content.

For readers who want to see the fuller Ethiopian Orthodox canon firsthand, including books not found in Western Bibles, a complete edition is available here. Among the texts unique to this canon is the Book of Enoch, which describes fallen angelic Watchers and their forbidden teachings — a modern annotated edition connecting that text to contemporary discernment questions is available here for readers who want to go deeper on that specific book.
What They Still Share
It would be a mistake to read this history as a story of two churches with nothing left in common. The Ethiopian Catholic Church deliberately preserved the Ge’ez Rite rather than adopting the Latin liturgy, meaning its services, chant, vestments, and much of its liturgical calendar remain recognizably continuous with Ethiopian Orthodox worship, drawing on the same Alexandrian liturgical family that shapes the Coptic tradition as well. A visitor unfamiliar with the doctrinal history could sit through an Ethiopian Catholic liturgy and, on sound and ritual alone, mistake it for an Orthodox one.
Both churches also continue to venerate the same pre-schism saints of Aksumite Ethiopia — Saint Frumentius, the Nine Saints who strengthened monasticism in the fifth and sixth centuries, and the long line of Ethiopian ascetics who shaped the country’s distinctive spiritual culture. The division that followed Chalcedon, and the deeper wound left by the Jesuit union’s collapse, did not erase fifteen centuries of shared history before either event. It simply added new chapters that the two churches now read differently.

FAQ
Frequently Asked Questions
Same Language, Same Land, Two Different Answers to Chalcedon
The Ethiopian Orthodox Tewahedo Church and the Ethiopian Catholic Church still sing much of the same ancient Ge’ez liturgy, still honor Saint Frumentius as their common father in the faith, and still trace their roots to the same fourth-century kingdom of Aksum. What separates them is not distance or unfamiliarity, but a fifth-century council and a seventeenth-century civil war that neither side has forgotten.
Understanding that history is the first step to understanding either church rightly — and to appreciating just how ancient, and how contested, the Christian story in Ethiopia really is.
