Теоретичні та методичні проблеми дослідження новітніх релігійних рухів у польській історіографії

The article analyzes the theoretical and methodological foundations of Polish research on the Reformation movements in Eastern Europe. It is established that basic scientific research represents the works of not only modern scholars, but also pre-revolutionary publications, which systematize and analyze historical and cultural material based on original sources and a large documentary heritage. It was found that a significant place in the study and systematization of archival materials belongs to Polish researchers of the 19th century. who not only carried out a thorough analysis of previous scientific developments contained in historical chronicles, but also summarized the original literary heritage accumulated by the Reformation-Protestant environment in the Polish, Lithuanian and Ukrainian lands. They studied and analyzed in detail their manuscript and printed meaning, scientific and educational sources, and the literature of school and cultural institutions. The authors continued their search for documents, carrying out fruitful analytical research into the religious and cultural life of Poland, the Grand Duchy of Lithuania, and the Polish-Lithuanian Commonwealth, which prepared a sufficient scientific basis for further research. It has been determined that modern Polish historiography on the problems of the Reformation and religious movements in Eastern Europe is represented by works that represent the multifaceted dimension of Renaissance-Reformation life in the Eastern European region, and explore the peculiarities of the religious, cultural, and educational activities of Socinianism, as well as its original literary monuments. An important scientific achievement of the mentioned authors is the disclosure of the structural and typological features of the Renaissance and Reformation in the Polish-Lithuanian Commonwealth, including in the Ukrainian lands. At the same time, some materials are devoted to individual pages of the history of freethinking in Ukraine. It is proven that most publications of Polish historiography lack a special analysis of the domestic religious situation, the disclosure of its features and the conditions of functioning in the religious and cultural life of Ukraine.Modern Polish historiography is limited to the study of the Polish Brethren movement in Ukrainian lands and the statement of the need to study mutual contacts between East Slavic religious movements and Polish-Lithuanian Arianism.It has been established that even in the latest historiography, which addresses the Reformation and religious and church life in Eastern Europe, Ukraine continues to be considered mainly as the most acceptable ground for the spread of religious and rationalist ideas.
