The contribution of the Cyrillo-Methodian religious and cultural mission has been described from different perspectives and points of view. The aim of the study is to examine how the basic principles of the Thessalonian brothers' mission are interpreted and how they are experienced and updated in the current religiosity and cultural tradition. In our study, we focus on current trends that appear in today's religiosity survival which are based on the results of the research carried out in 2020, related to the prospects of development of religiosity in Slovakia. From a methodological point of view, the text compares the underlying principles of religiosity, which are integrated in the teachings of Cyril and Methodius with current trends and ideas of the younger generation about their own religiosity. The aim of the study is to determine whether in the scenarios of the development of religiosity we find the presence of the Cyrillo-Methodian tradition and how they are transformed in the current conditions.
