Abstract
The article presents the first attempt of a complete and systematic analysis of historic and theological publications of teachers and pupils of the Kyiv Theological Academy in the second half of the 19th – beginning of 20th century in the field of studying the history of relations of Catholicism and Protestantism with Orthodox on the Ukrainian lands. The specifics of Kyiv academic historians studies was determined by the social and-political circumstances in the middle of the 19th century and denoted by an attempt to comprehend this issue in the perspective of the history of interconfessional relations of two Western Christian traditions with the eastern tradition of Orthodoxy in the historical gap of the 16th – 17th centuries – the period of the largest confrontation in confessional relations in Ukraine. The author clarifies the characteristic features of researching the question of inter-confessional interaction in the 15th – 17th centuries, which are expressed in attempts to describe the coexistence of three denominations as multidimensional and provoking а variety of different interpretations. Historical studies present the attempt to show confessional interaction in the political and legal aspects and to provide historical interpretations to the ground of philosophy of history. The article proves the tendency of Kyiv academic researchers to move away from the established Russian historiography of the 19th century view at confessional relations in Ukraine through the prism of hard confrontation and outline in religious life Ukraine conditions and circumstances of inter-confessional dialogue. Also, historians in their studies repeatedly note the significant educational and outlook influence of Western Christian denominations on the formation of educational, cultural, theological, literary traditions in Ukraine.
