It examines the influence of the Catholic Church on the formation of the legal systems of both countries, in particular on the development of administrative practices, moral and ethical principles, and legal institutions.

Analyzing the role of the Catholic Church in the context of inter-state relations between Poland and Ukraine, the article emphasizes its importance as a mediator in peace-making processes, as well as an institution that helped maintain political stability and law and order within both states. Particular attention is paid to the development of legal culture in both countries as a result of this interaction, as well as the challenges facing contemporary law in the light of secularization and globalization.
