“Uniatism” is not a neutral term. It was coined as a pejorative — from unia, the Polish word for the unions by which Eastern Christian communities entered communion with Rome — and it has never shed its derogatory character. Orthodox theology uses it to describe what it regards as a colonial strategy: the detachment of Eastern Christians from their authentic Orthodox inheritance through political pressure, the offer of privileges, and the fiction of “union” that required surrendering the substance of Eastern ecclesiology while retaining only its liturgical surface. The Eastern Catholic churches that resulted from this strategy are, in the Orthodox account, a problem — a standing wound in the body of Eastern Christendom that the ecumenical movement must eventually heal by restoring these communities to the Orthodoxy from which they were extracted.

This article accepts the Orthodox framing — and then examines it against the evidence.

The evidence includes eighteen million living Eastern Catholics. It includes the martyred bishops of the Ukrainian Greek Catholic Church, tortured and killed in Stalin’s camps. It includes the Melkite Greek Catholic patriarch who stood at the Second Vatican Council and told the Latin bishops, in a liturgical tradition identical to that of his Orthodox neighbors, that they were confusing Catholicism with Latinism. It includes Pope Benedict XVI’s formal characterization of the 1946 forced liquidation of the Ukrainian Greek Catholic Church as a “pseudo-synod.” And it includes the Balamand Statement itself — a document that conceded something real to the Orthodox, affirmed something essential for Eastern Catholics, and ultimately satisfied no one.

I. Twenty-Three Churches — An Introduction

The Catholic Church is not a single rite. It is, in the language of the Second Vatican Council and the 1990 Code of Canons of the Eastern Churches, a communion of twenty-four particular churches — the Latin Church and twenty-three Eastern Catholic churches, each sui iuris (“of its own law”), possessing its own canonical tradition, liturgical rite, theological patrimony, and internal governance. Each is fully Catholic. None is a subordinate appendage of the Latin Church. The Eastern Catholic churches are organized into five great liturgical families — Byzantine, Chaldean/East Syriac, Antiochene/West Syriac, Alexandrian, and Armenian — each tracing to one of the ancient apostolic centers of Christianity:

The canonical status of these churches deserves emphasis because it is often misunderstood even by Catholics. Each sui iuris church governs itself — it has its own synod, its own law, its own marriage discipline, its own selection of bishops. None of this is subject to Latin Church law. The Eastern Catholic churches retain married parish clergy, communion under both species for infants, the leavened bread of the Eucharist, the Eastern calendar, the iconographic tradition, and the patristic theological heritage of the East. The Petrine primacy does not override these particularities; in the Catholic understanding, it guarantees them.

II. The Orthodox Charge — Stated at Its Strongest

The Orthodox critique of these churches deserves to be stated as its best defenders state it, not as a caricature. It has three distinct components:

The ecclesiological objection is the most sophisticated. It holds that the Eastern Catholic churches presuppose a defective “return ecclesiology” — the Catholic assumption that Orthodox churches are schismatic communities that need to “come back” to the one true Church. This assumption, Orthodox theologians argue, was already implicitly abandoned by the Second Vatican Council’s recognition of Orthodoxy as a genuine sister church possessing valid sacraments and apostolic succession. Metropolitan John Zizioulas of Pergamon — the Orthodox Church’s most prominent communion ecclesiologist and for many years the Orthodox co-chair of the international Catholic-Orthodox dialogue — has pressed this argument with particular force: if Orthodoxy is genuinely a sister church, then the Eastern Catholic churches, whose original reason for existing was to serve as a bridge by which Orthodox communities would enter Catholic communion, have outlived their theological justification and belong to a superseded ecclesiology.

The historical objection is the most emotive. The Union of Brest (1596) is presented as a coerced transaction: Polish-Lithuanian state power combined with Jesuit missionary pressure induced Ruthenian bishops exhausted by Protestant encroachment and resentful of Constantinopolitan neglect to sign their communities into the Latin orbit. The Union of Uzhhorod (1646) is presented similarly: Habsburg Counter-Reformation patronage and Calvinist pressure on Ruthenian serfs produced a union shaped by political necessity rather than theological conviction. In the most extreme Orthodox telling, the Greek Catholics of Ukraine are not authentic inheritors of a voluntary union but captives of a four-century-old colonial project — a fiction the Moscow Patriarchate was at least honest enough to liquidate in 1946.

The pastoral objection is the most practical. The existence of parallel Catholic and Orthodox patriarchates of Antioch, parallel Byzantine Catholic and Orthodox bishops in Ukraine, parallel Armenian Catholic and Apostolic patriarchs — this parallel structure makes genuine Catholic-Orthodox dialogue structurally impossible, because every Orthodox bishop must treat his Catholic neighbor not as an ecumenical partner but as the representative of a communion that has taken a portion of his flock.

These three objections are serious. They deserve honest engagement. And the most honest engagement begins not with a counter-argument but with a counter-fact.

III. The Melkite Argument — The Living Liturgical Refutation

The Melkite Greek Catholic Church is the most elegant refutation of the Orthodox uniatism charge, because it does not argue — it simply exists. Founded when a split in the Patriarchate of Antioch in 1724 produced two parallel successions — one Catholic (under Cyril VI Tanas), one Orthodox — the Melkites celebrate the identical Divine Liturgy of St. John Chrysostom as their Greek Orthodox neighbors. The same texts. The same music. The same fasts. The same Octoechos, the same iconographic tradition, the same Arabic and Greek. Approximately 1.6 million Melkites worldwide celebrate a liturgy indistinguishable to an uninformed visitor from the liturgy celebrated in any Greek Orthodox parish on the same block.

The Melkite existence demolishes the claim that authentic Eastern Christianity and communion with Rome are incompatible. If a Melkite can celebrate the Divine Liturgy of St. John Chrysostom in full, unreduced, unlatinized integrity as a Catholic — and he can, and does, every Sunday — then the Orthodox claim that accepting the Pope requires abandoning the East is simply false. It is false as a theological argument, and the Melkites make it false as a lived reality.

The most decisive Melkite voice on this question belongs to Patriarch Maximos IV Saigh, who led the Melkite church from 1947 to 1967 and whose interventions at the Second Vatican Council were among the most consequential of any Council Father. Maximos repeatedly refused to address the Council in Latin — the first patriarch to do so — on the grounds that Latin was not a Catholic language but a Western language, and that the East had its own equally Catholic voice. His argument was stated with the clarity that only a living Eastern Catholic could achieve:

Maximos refused the cardinalate three times — on the principle that for a patriarch of apostolic origin to accept a rank within the Latin Church’s administrative structure would be to concede the Latin equation — until Paul VI reconstituted the College of Cardinals as the senate of the universal Church rather than a Latin institution. Then he accepted. The distinction matters: he was not resisting Rome; he was insisting that Rome recognize the full catholicity of the East, which is precisely what the Eastern Catholic churches embody.

IV. The Historical Record — What the Unions Actually Were

The Orthodox historical account of the great unions is not fabricated — it draws on real evidence of political pressure and ecclesiastical dysfunction. But it systematically suppresses the evidence on the other side, and intellectual honesty requires naming both.

The Union of Brest was not imposed on the Ruthenian church by Latin missionaries. It was initiated from within the Ruthenian Orthodox episcopate itself. Metropolitan Mykhailo Rohoza and Bishops Ipatii Potii and Cyril Terletsky led the delegation that presented the formal Act of Union to Pope Clement VIII in Rome on 23 December 1595. The terms they negotiated preserved the Slavonic liturgy, the married priesthood, local episcopal election, and — crucially — the Nicene Creed without the filioque insertion. These were not the concessions of men who had been bribed into abandoning their tradition. They were the conditions of men negotiating the preservation of that tradition under circumstances of considerable difficulty: Calvinist and Protestant pressure, Ottoman military threat, and the increasingly distant and politically compromised Patriarchate of Constantinople under Ottoman domination.

That the union was contested — that Prince Constantine Ostrogski organized the anti-union Orthodox council at Brest simultaneously with the pro-union Catholic council — is not evidence that the union was illegitimate. It is evidence that the Ruthenian church was divided, as churches in crisis generally are. The subsequent history of Ukrainian Greek Catholicism, spanning four centuries, through the destruction of the Cossack era, the partitions of Poland, the Habsburg period, the Soviet liquidation, and the underground church, is not the history of a colonial fiction. It is the history of a people’s faith.

The Union of Uzhhorod of 1646 deserves a more careful reading than the Orthodox account provides. Sixty-three Ruthenian Byzantine-rite priests signed at Uzhhorod Castle on 24 April 1646 in the presence of the Catholic Bishop of Eger. The Orthodox account emphasizes Habsburg Counter-Reformation patronage and political pressure — and these were real factors. But the account that omits the alternative is incomplete: the Ruthenian clergy of Royal Hungary faced not a simple choice between authentic Orthodoxy and coerced Catholicism, but a genuine crisis in which Calvinist lords were seizing Orthodox churches, Orthodox clergy had no canonical bishop of their own, and the Moscow Patriarchate — their nominal ecclesiastical superior — was geographically and politically unreachable. Union with the Habsburg-protected Catholic Church was, for those 63 priests, a measure of pastoral survival for their communities, not surrender to a colonial power. That the terms preserved the Byzantine liturgy, married clergy, and Eastern calendar confirms that what they sought and received was protection for their tradition, not absorption into the Latin Church.

V. The Lviv Pseudo-Sobor of 1946 — The Martyrological Refutation

The most powerful refutation of the Orthodox uniatism narrative is not an argument. It is the Lviv Pseudo-Sobor of March 1946 and everything that preceded and followed it.

On 15 March 1945 — ten months before the end of World War II — Joseph Stalin personally approved a secret NKGB instruction titled “On the measures aimed at the estrangement of the Greek-Catholic Church from the Vatican and its subsequent annexation to the Russian Orthodox Church.” The plan was straightforward: arrest the entire hierarchy, coerce the lower clergy into apostasy, convene a “synod” without bishops to vote for liquidation, and hand the church’s buildings to the Moscow Patriarchate. On 11 April 1945, all five Greek Catholic bishops present in Soviet-controlled western Ukraine were arrested in a single coordinated operation.

With the entire hierarchy imprisoned, a Soviet “Initiative Group” of three priests — led by Fr. Havryil Kostelnyk, consecrated Orthodox by the Moscow Patriarchate specifically for this purpose — convened 216 priests at St. George’s Cathedral in Lviv on 8–10 March 1946. By a show of hands they voted to “revoke the 1596 Council of Brest, eliminate the Union, break from the Vatican, and return to the bosom of the Russian Orthodox Church.” Pre-written telegrams of thanks to Stalin, Khrushchev, and Patriarch Alexy I of Moscow went out the next morning. The Moscow Patriarchate accepted the merger. Over 1,400 priests and 800 nuns who refused to comply were sent to the gulag. More than 4,000 Greek Catholic church buildings were transferred to the Russian Orthodox Church.

Pope Benedict XVI called this event by its right name in his letter of 22 February 2006 to Cardinal Lubomyr Husar of the UGCC:

For forty-three years after the Pseudo-Sobor, the Ukrainian Greek Catholic Church was the largest forbidden church in the world. Bishops were consecrated in secret — Slipyj consecrated Vasyl Velychkovsky in a Moscow hotel room in 1963 on his way into Roman exile, and the chain continued underground through the Soviet decades. Liturgies were celebrated in forests, barns, and apartments. Priests heard confessions and administered last rites at risk of re-arrest. Sisters renewed their vows in private homes. The church that the Moscow Patriarchate had declared absorbed lived on, beneath the surface, by the faith of its people and the protection of an institution the Soviets could not touch: the universal Catholic communion and its bishop, the Pope of Rome.

The UGCC was legalized on 1 December 1989. On 27 June 2001, Pope John Paul II celebrated the Divine Liturgy at the Lviv Hippodrome before more than one million faithful — and beatified twenty-seven martyrs of the Ukrainian Greek Catholic Church, including Bishops Budka, Charnetsky, Khomyshyn, Liatyshevsky, Romzha, Lakota, Kotsylovsky, Velychkovsky, Sleziuk, and Lukach; the Redemptorist priest Zynoviy Kovalyk; the laywoman Tarsykia Matskiv; and the foundress of the Sisters Servants of Mary Immaculate, Josaphata Hordashevska.

The Orthodox charge is that the Eastern Catholic churches are a colonial problem. The martyrs of Lviv are the answer.

VI. The Balamand Statement — What It Actually Says

The 1993 Balamand Statement is the most significant Catholic-Orthodox document of the modern ecumenical era. Its full title is Uniatism, Method of Union of the Past, and the Present Search for Full Communion. It was produced by the Seventh Plenary Session of the Joint International Commission for Theological Dialogue between the Catholic Church and the Orthodox Church, meeting at the Balamand School of Theology in Lebanon, 17–24 June 1993.

Six autocephalous Orthodox churches were not represented: Jerusalem, Georgia, Serbia, Bulgaria, Greece, and Czechoslovakia. Most significantly, the Moscow Patriarchate was absent — not for logistical reasons but for principled ones. Russia had specific objections to any document that might legitimize the Ukrainian Greek Catholic Church’s canonical existence, given the Moscow Patriarchate’s direct role in the 1946 Lviv Pseudo-Sobor. A commission document affirming that Eastern Catholic churches “have the right to exist” was, from Moscow’s perspective, a document vindicating the very community whose liquidation Moscow had facilitated and ratified. Russia’s absence meant the document could never claim the consent of the Orthodox world’s largest communion — and ensured it would remain contested in precisely the territory where it mattered most. The Eastern Catholic churches were not invited either — a structural irony noted publicly by Cardinal Lubomyr Husar, since the document’s subject was their existence and their future. The document contains 35 numbered paragraphs and two governing claims that cannot be read in isolation from each other:

The document’s official status is important to understand precisely: it is not binding magisterial teaching on either side. Its own communiqué states that “this common document belongs to the responsibility of the Commission itself, until the competent organs of the Catholic Church and of the Orthodox Churches express their judgement in regard to it.” No such formal judgement has been rendered by either. Cardinal Walter Kasper, then president of the Pontifical Council for Promoting Christian Unity, stated the official Catholic interpretation in November 2009: “The Balamand document of 1993 is still valid, according to which this is a phenomenon of the past that took place in unrepeatable circumstances. It is not a method for the present or the future.” That is the key phrase: the rejection of uniatism as a method applies to future strategy. It does not retroactively delegitimize the churches that already exist and have the right to exist.

VII. Eastern Catholic Reaction — Validation and Wound

The Eastern Catholic reception of Balamand was neither uniform nor fully accepting. Cardinal Myroslav Lubachivsky, Major Archbishop of the UGCC from 1984 to 2000, offered a qualified acceptance — he pledged to apply the practical rules of the document in Ukraine but raised reservations, most pointedly the observation that “the UGCC is a sister church not only to the Orthodox Church, but to the Roman Catholic Church as well.” That correction cuts to the heart of the matter: Balamand’s framers had treated the Eastern Catholic churches as a problem in Catholic-Orthodox relations. Lubachivsky insisted they were a full partner in those relations, not merely an object of them.

The sharpest formal Eastern Catholic protest came from the Romanian Greek Catholic bishops, who on 8 July 1993 — two weeks after Balamand — wrote to Pope John Paul II formally denouncing the document and rejecting all documents produced by the international dialogue commission. Their standing was unimpeachable: their church had been suppressed by Communist Romania in 1948, its bishops imprisoned, its property seized and given to the Romanian Orthodox Church, and its faithful forced into apostasy for forty years. It had only just been restored in 1989. For these bishops, who had survived or inherited the direct experience of communist-Orthodox collaboration against their church, a document that treated “uniatism” as a problem requiring concessions to the Orthodox was not ecumenism. It was asking them to validate the logic of their own persecution.

Cardinal Lubomyr Husar, the UGCC’s Major Archbishop from 2001 to 2011, tried to find a middle path. In a 2004 interview he stated: “If we take Uniatism in this classical way of trying to re-establish unity, we as well do not accept it. We were tricked into it. It was not the intention of our bishops at the end of the 16th century.” This is the most sophisticated Eastern Catholic response to Balamand: accept its rejection of uniatism as a mission strategy while reframing the historical unions as something other than uniatism in the pejorative sense — as communities that emerged from genuine theological conviction under historical pressure, and whose continued existence reflects the ongoing faith of millions, not the lingering effect of a discredited strategy.

VIII. The Structural Catholic Argument — The Petrine Office as Guardian

The deepest Catholic argument about the Eastern Catholic churches is not historical or apologetic. It is ecclesiological. And it turns the Orthodox uniatism charge inside out.

The Orthodox charge assumes that the Petrine primacy is the enemy of Eastern particularity — that accepting the Pope means accepting a Latin-centered uniformity that will eventually absorb and dissolve the authentic Eastern inheritance. The existence of the Eastern Catholic churches is the empirical refutation of this assumption. They have preserved their liturgical rites, their canonical traditions, their theological patrimony, their married clergy, their Eastern calendar and iconographic traditions — and they have preserved them because of the Petrine office, not in spite of it.

The contrast with the Russian Orthodox Church’s experience in the Soviet period is instructive. The Moscow Patriarchate operated under the Soviet state on terms the state dictated. Patriarch Sergius’s 1927 Declaration of Loyalty accepted Soviet conditions for the church’s survival; the NKVD monitored and controlled Orthodox hierarchical appointments; the church was permitted to function as a tool of Soviet policy. The Moscow Patriarchate cooperated with the 1946 liquidation of the UGCC — accepting its buildings, absorbing its clergy, and ratifying its destruction with the theological language of “reunification.” It had no external advocate who could resist Soviet power.

The Ukrainian Greek Catholic Church had one: the Pope of Rome. John XXIII negotiated Slipyj’s release in coordination with the Kennedy administration. Paul VI elevated the Major Archbishopric and maintained its canonical existence in exile. John Paul II made the UGCC’s survival and restoration a personal priority, visited Lviv in 2001, beatified its martyrs, and lobbied relentlessly for the return of its property. The universal Catholic communion maintained diaspora hierarchies in Philadelphia, Winnipeg, Curitiba, Buenos Aires, and Sydney that preserved the church’s canonical continuity through decades when Galicia could not.

This is not an argument for papal monarchy. It is an argument for what the Petrine office actually is in Catholic ecclesiology: a servant of the unity and integrity of the particular churches, a voice that can speak for the voiceless, a structure that exists above and across the political boundaries that states use to destroy what they cannot control. The Eastern Catholic churches are not evidence against that office. They are evidence for it. And the diversity of paths by which they entered Catholic communion only strengthens the case: the Syro-Malabar Church of Kerala — 4.5 million faithful tracing their origins to Thomas the Apostle, entering fuller communion with Rome through missionary contact over centuries, with nothing resembling the political pressure of Brest or Uzhhorod — is an independent proof that the Eastern Catholic phenomenon cannot be reduced to a single coercive colonial model. Different churches, different centuries, different continents, different circumstances — the same living reality of Eastern Christianity in full communion with Peter.
