The author examines the impact of a large number of Ukrainian Christians of different denomi­nations on the transformation of interchurch relations in Polish churches and their rethinking of confes­sional identity and pastoral approaches. The article examines the church environment of the three main denominations: Catholicism, Orthodoxy, and Protestantism. The research method used includes eleven semi-structured interviews with clergy and theologians of different denominations, as well as discourse analysis of church documents and media. As a result, new modes of ecumenical interaction have been identified: from institutional dialogue to practical concelebration and humanitarian cooperation. Military migration has become a catalyst for changes in Polish ecumenism from formal diplomacy to solidarity action. This experience demonstrates that in times of war, ecumenism ceases to be only a theological concept and becomes a tool for responding to social challenges.enAttribution-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nd/4.0/ecumenismreligious migrationUkrainian churches in Polandinterchurch dialoguewar in Ukrainereligious field in Polandinfo:eu-repo/semantics/article10.31743/vv.18582
