“Uniatism” is the name — coined from the Eastern-rite unions like the Union of Brest (1596) — for a historic strategy: seeking Christian unity by detaching groups of Eastern Christians from their Orthodox Mother Churches and attaching them to Rome individually, while they keep their Byzantine rite. The word slides between three things, and they must be kept distinct: the historical unions, the Churches they produced, and the method itself. Only the method is what the dialogue renounced.

For the Orthodox the word marks a real wound, and the grievance has teeth. The Union of Brest split the Kyivan Church in two — two bishops withdrew their signatures and led the opposition, and rival Churches contested the same parishes and people for centuries. The Transylvanian union (1698–1700) was promoted by the Habsburgs and Jesuits, with Orthodox believers denied civil rights until they accepted it. The contest turned violent — the Greek-Catholic Archbishop Josaphat Kuntsevych was killed by an Orthodox mob in 1623. And the Catholic–Orthodox dialogue itself confessed the later abuses: that missionary activity aimed “to bring them back,” that “certain requirements of the religious freedom of persons… were forgotten,” that “Christians were rebaptized” (Balamand §10).

But the mirror grievance must be honored with equal force, because “uniatism” is a hostile abstraction laid over living Churches. The word reduces real communities — Ukrainian, Ruthenian, Melkite, Romanian Greek Catholics — to a discredited technique “of the past.” They are not a strategy; they are Churches whose faithful freely sought Rome, kept their heritage, and suffered for the choice (the Ukrainian Greek Catholic Church was crushed under Soviet rule and rose again from the catacombs). Their unions were often acts of self-preservation — at Brest, to secure their rite and married clergy against Latinization; in Transylvania, to win Romanians the civil rights the others enjoyed. To call their founding a regrettable method is itself an injury, and they have said so.

The Church can say two true things at once. As a method for future unity, uniatism is renounced: Rome no longer pursues reunion by drawing communities out of Orthodoxy parish by parish — the goal is full communion between the Churches as Churches, and this “form of ‘missionary apostolate’… can no longer be accepted… nor as a model of the unity our Churches are seeking” (Balamand §12). And the Eastern Catholic Churches that already exist are legitimate and not to be dissolved: the same document affirms their “right to exist” (§3), and Vatican II teaches they are “of equal dignity” (Orientalium Ecclesiarum §3). So the slur must not be allowed to do its work: the method is repudiated and its abuses confessed — but “uniate,” wielded as a weapon, cannot argue real Churches and real martyrs out of existence.
