Why a WWII massacre dispute is testing Poland’s support for Ukraine
Catholic leaders from Poland and Ukraine jointly appealed for reconciliation over a WWII memory dispute, urging governments to avoid divisive language. The dispute centers on Ukraine's naming of a military unit after UPA heroes, which Poland views as a symbol of the Volhynia massacres that killed about 100,000 Polish civilians. Poland responded by revoking President Zelenskyy's Order of the White Eagle, sparking public debate and highlighting deep national divisions. The conflict threatens Ukraine's EU accession hopes, as the controversy raises questions about its handling of historical grievances. The joint appeal underscores the role of the Catholic Church in mediating between the two nations amid rising tensions.

Poland and Ukraine’s long‑standing dispute over the World War II‑era Volhynia massacres has escalated into a diplomatic crisis that threatens Kyiv’s bid for European Union membership, prompting a rare joint appeal from senior Catholic leaders in both countries for reconciliation and “disarmament of language.” 1 2
The Volhynia massacres (1943‑1945) saw the Ukrainian Insurgent Army (UPA) kill an estimated 100,000 ethnic Poles in territories that shifted between Polish and Ukrainian control during the war. Poland officially labels the events a genocide, a characterization rejected by Ukraine, which views the UPA as a resistance movement against Nazi and Soviet domination. 1
On 26 May 2026 Ukrainian President Volodymyr Zelenskyy named a military unit after the “heroes of the UPA.” The decision ignited outrage in Poland, where the UPA is associated with the Volhynia atrocities. 2
On 29 June 2026 three Polish cardinals (Grzegorz Ryś, Konrad Krajewski, Kazimierz Nycz) and two Ukrainian prelates (Major Archbishop Sviatoslav Shevchuk and Cardinal Mykola Bychok) issued a statement urging both governments to seek forgiveness, forgive one another, and avoid “narrow national interests.” The appeal invoked St John Paul II’s 2003 call for the two peoples not to remain enslaved by painful memories. 1 2
Polish public opinion is sharply divided, with a majority favoring the removal of Zelenskyy’s honor. Ukrainian officials view the revocation as an affront to national sovereignty. The dispute is seen as a potential obstacle to Ukraine’s EU accession, which requires unanimous support from existing member states, including Poland. 1
President Zelenskyy has declared that Ukraine will not be dictated on which historical figures it honors, announcing plans for a national pantheon. Polish officials warn that this stance could jeopardize Kyiv’s EU aspirations. Warsaw is likely to demand a clearer Ukrainian acknowledgment of the scale and character of the Volhynia massacres, while Kyiv remains reluctant to alter its commemorative policies. 2
The Catholic appeal emphasizes moral responsibility, forgiveness, and a shared Christian ethic as a pathway to de‑escalation. However, entrenched historical narratives and political calculations make a swift compromise unlikely, leaving the Poland‑Ukraine relationship and Ukraine’s EU trajectory in a delicate balance. 1 2*
Examine how Catholic mediation shapes Poland‑Ukraine historical reconciliation
Catholic “mediation” in Poland–Ukraine historical reconciliation works less like partisan arbitration and more like a moral and spiritual framework that enables truth-telling, repentance, forgiveness, and a “reconciled remembrance” capable of supporting civic peace. In John Paul II’s message for the 11 July commemoration of the Volhynia tragedy, the Church’s role is shown through three interconnected mediations: conscience, memory, and collaboration.
Catholic mediation begins by insisting that reconciliation is not merely a diplomatic posture; it requires an interior disposition—an honest examination of conscience. For John Paul II, both Poles and Ukrainians feel “more and more acutely the need for a deep examination of conscience,” precisely because the wounds of the past still press on the present.
He connects this to conversion in two directions:
In other words, Catholic mediation does not treat reconciliation as forgetting or smoothing over. Instead, it treats reconciliation as repentant truth that can ground future justice and peace.
A second mediating element is the Church’s distinctive approach to memory. John Paul II frames the Jubilee of the Year 2000 as a model: “the Church asked forgiveness publicly for the sins of her children and at the same time pardoned those who had offended her in various ways,” aiming “to purify the memory of sorrowful events from all sentiments of bitterness and revenge.”
This is crucial for historical reconciliation in a contested past: Catholic mediation seeks to remove the internal dynamics that make conflict self-perpetuating—resentment and revenge—while still allowing remembrance to remain serious and truthful.
John Paul II explicitly proposes that the attitude of the Jubilee be taught to “young generations” so that they do not face the future “conditioned by a history of suspicion, preconceptions and violence,” but “in a spirit of reconciled remembrance.”
So Catholic mediation shapes reconciliation by redefining what it means to remember: not as a weapon or a demand for hostility, but as a purified witness that can support peace.
A third element is the Church’s insistence that forgiveness is not opposed to justice; it is presented as its completion. John Paul II states: “there is no justice without forgiveness” and that collaboration without reciprocal openness would be “brittle.”
He then applies this principle directly to the Polish–Ukrainian context:
Notice the symmetry: Catholic mediation is not one-sided. The logic is both pardon received and pardon requested, anchored in the Christian claim that forgiveness is patterned on God’s action in Christ.
This shapes historical reconciliation by giving it a communal moral structure: the path forward requires acts of forgiveness and penitential responsibility, not only mutual statements of regret or pragmatic agreements.
Catholic mediation also operates through institutional and pastoral encouragement—particularly the cooperation of Christian communities and the engagement of civil leaders.
John Paul II “delighted” that “the Christian communities of Ukraine and Poland are promoting this commemoration to help heal the wounds of the past,” and he encourages both peoples to persevere in “collaboration and peace.”
Importantly, he extends the appeal beyond ecclesial circles: he addresses “a respectful thought” to the “Presidents and their respective civil Authorities,” hoping they will advance “constantly in concord and peace,” and he imparts a special Apostolic Blessing for those joining the celebrations.
Thus, Catholic mediation acts as a bridge between:
From these themes, Catholic mediation shapes reconciliation by combining four claims:
A limit of the provided sources: they focus on the Church’s moral/spiritual mediation in connection with the 11 July commemoration and the Jubilee model. They do not detail specific diplomatic mechanisms or institutional mediation procedures beyond exhortation and encouragement.
In John Paul II’s vision, Catholic mediation shapes Poland–Ukraine historical reconciliation by teaching reconciliation as a path of conscience (examination and conversion), purified memory (reconciled remembrance), and a forgiveness-founded justice, promoted through commemoration and collaboration that reaches into civic life.
