The Romanian government encountered unexpected difficulties after the First World War with the increase of religious minorities, particularly evangelicals in the newly acquired border region of Bessarabia. International affiliations and increasing success in rural areas led government officials and the Romanian Orthodox Church to label these groups as foreign pawns or socially deviant sectarians. The Baptist Church in Chișinău proved a special case of concern as its leadership included a Jewish man, Lev Averbuch. Averbuch's congregation was a diverse religious community, filled with Romanians, Russians, Bulgarians, Jews, Greeks, and others. Their multi-ethnic composition, multi-lingual services, ties to international organisations, and controversial sermons speaking out against nationalism and antisemitism were used by police and Orthodox Church authorities to paint them as a threat to national security. The analysis of Averbuch's interwar community of Jewish Christians in Chișinău shows the region was not a homogenous religious space and that religious identity was of greater value than national identity. It provides insight into the fluidity of religious, ethnic, and even geographic borders, and how policies of national consolidation were challenged at the local level by religious minorities during Europe's tumultuous interwar years.
