Supporting a sustainable world in a situation of war is the background to this study. Additionally, interdisciplinarity forms a part of the dialogical ecosystem of searching for suitable solutions in a complex reality. For such purposes, in this contribution, the co-authors reflect on an actual instance of war. The first author provides a theological, socio-political and philosophical framework for an understanding, based in realism, of the relationship between theology and politics. The second author provides a first-hand case description from Riga, Latvia, of a politically-linked ecumenical project to assist Ukrainian refugees from the Russian invasion.
