In the history of religious organizations of Western Ukraine in the 20-30th years of the XX century. The activity of such an early protestant denominational formation as the Ukrainian Evangelical-Reformed Church occupies a prominent position. Among UCRC researchers there are several approaches to the preconditions for the birth of the Ukrainian Calvinistic movement in Western Ukraine. In particular, O. Dombrovsky, studying the historical preconditions for the formation of the UREC in Western Ukraine, expressed the view that the formation of the Calvinist cell should be considered in the broad context of the Ukrainian national revival of the 19th and 20th centuries, a new assessment of the religious factor in public life proposed by the Ukrainian radical activists ( M. Drahomanov, I. Franko, M. Pavlik), and significant socio-political, national-cultural and spiritual shifts caused by the events of the First World War. Other researchers of Ukrainian Calvinism, who based their analysis on the confessional-polemical approach (I.Vlasovsky, M.Stepanovich), interpreted Protestantism in Ukraine as a product of Western cultural and religious influences, alien to Ukrainian spirituality and culture.
