This paper revisits the role of the Russian Orthodox Church (ROC) as a moral norm entrepreneur in international affairs—an inquiry that builds on and updates findings first presented a decade ago. Over the past ten years, the Moscow Patriarchate has moved from being a peripheral cultural actor to an integral component of Russia's broader strategy of normative statecraft. Through its advocacy of so-called "traditional values," the ROC has sought to position itself as a global defender of moral order against what it depicts as Western moral relativism and liberal decadence. This paper examines how Russia's full-scale invasion of Ukraine in 2022 has transformed this project—both in its ideological substance and its transnational reach. The analysis traces continuities and ruptures in the Church's engagement with international organizations, conservative NGOs, and transnational religious networks that previously amplified Russia's "moral sovereignty" narrative. It assesses the erosion of the ROC's credibility in parts of the Global South and among interfaith partners, while also documenting new alliances with illiberal political and religious actors who interpret the war as a civilizational confrontation. The paper argues that the Patriarchate's moral diplomacy has shifted from soft power projection to a more defensive, even militant, posture—one that merges spiritual rhetoric with geopolitical justification for aggression. By revisiting the concept of the ROC as a moral norm entrepreneur ten years later, the study highlights how war, sanctions, and international isolation have reconfigured the very mechanisms through which religious discourse operates in Russian foreign policy. The findings offer broader insight into the fragility and instrumentalization of faith-based norm entrepreneurship under conditions of authoritarian consolidation and global polarization.
