Russian Orthodox boycott of Pope Leo XIV’s Nicaea anniversary event in Turkey exposes persistent Orthodox schism and a quiet but decisive Vatican pivot away from Moscow.
Newsroom (03/12/2025 Gaudium Press ) When Pope Leo XIV stood Friday amid the ruins of the basilica that once hosted the First Ecumenical Council of 325 and urged Christian leaders to “strongly reject the use of religion for justifying war, violence, or any form of fundamentalism or fanaticism,” one major Christian voice was conspicuously silent because it was entirely absent: the Patriarchate of Moscow.
No delegate from the Russian Orthodox Church – still the largest Orthodox body on paper – crossed the Sea of Marmara to attend the 1700th anniversary commemoration of the Council of Nicaea. Vatican ecumenical chief Cardinal Kurt Koch explained the empty chairs with studied neutrality: “The Catholics have invited Catholics, and the Orthodox invited Orthodox.” Moscow, however, had pointedly declined the Orthodox invitation.
The boycott was the latest public symptom of a deepening crisis in global Orthodoxy and a quiet but unmistakable reorientation in Rome’s approach to Russia under Pope Leo XIV.
The rupture traces back to 2018, when Ecumenical Patriarch Bartholomew I of Constantinople granted autocephaly to an independent Orthodox Church of Ukraine – a move Moscow denounced as illegitimate and that triggered a complete break in communion between the two ancient patriarchates. Russia’s 2022 invasion of Ukraine calcified the divide, while the Vatican’s 2023 document Fiducia Supplicans further chilled any prospect of a second Francis-Kirill summit after their 2016 Havana breakthrough.
Seventeen centuries ago, Emperor Constantine summoned the world’s bishops to this same lakeside town to restore order threatened by the Arian controversy. Today, the Moscow Patriarchate – heir to Byzantium’s imperial legacy – functions less as an independent voice than as an arm of Kremlin policy. Active believers inside Russia are few, yet Patriarch Kirill remains a reliable amplifier of the regime’s narrative, a role Pope Francis once dismissed with the stinging phrase that a patriarch cannot “lower himself to become Putin’s altar boy.”
Leo XIV has chosen a different path. Unlike his predecessor Pope Francis, who occasionally voiced understanding for Moscow’s geopolitical grievances – including suggestions that NATO expansion may have “provoked” Russia or that Kyiv should show “the courage of the white flag” – Leo has offered no such openings. He has affirmed the right of nations to self-defense, described Ukraine as “martyred,” and expressed measured hope that figures such as Turkish President Recep Tayyip Erdogan might broker dialogue and a ceasefire.
Crucially, he has not chased Moscow’s favor. By respecting the Orthodox invitation protocol and declining to press for Russian participation, Leo allowed the Moscow patriarchate’s absence to stand as its own statement – and ensured the Vatican would not be seen as meddling in an intra-Orthodox dispute or courting a church widely viewed as compromised by its alignment with Russian state power.
In an event meant to celebrate the council that gave Christianity the Nicene Creed and the famous “one iota” of difference that preserved orthodoxy, Moscow’s self-exclusion spoke volumes. For Pope Leo XIV, still in the early chapters of his pontificate, the empty Russian chairs in Nicaea may mark the clearest signal yet: Rome is no longer willing to pay the ecclesiastical or moral price of keeping a seat warm for a patriarchate that has chosen alignment with aggression over communion with its brother churches.
