ENThe paper presents an analysis of the discursive construction of Christianity and interdenominational and interreligious relations in the Christian persecution discourse of Lithuanian Catholic anti-genderist groups. The analysis is based on a case study of the discourse developed by Tomas Viluckas in his news portal, Laikmetis (laikmetis.lt), which was operationalised by the Christian Professional Union. The analysis shows that not only does religion have an influence on gender politics, but current debates on gender politics in broader society also shape religion and interreligious relations. Public debates on the ratification of the Istanbul Convention in Lithuania fuelled the perceived relevance of the idea of Christian persecution. This discourse highlighted the multidenominational nature of Christianity and challenged the dominant vision of the national Catholic Church as the sole defender of what is imagined as the traditional Lithuanian family, even if the hierarchy of religious communities in Lithuania features the Roman Catholic Church at the top. Keywords: interdenominational and interreligious relations, Christian persecution discourse, gender politics. [From the publication]
