Masaryk's interpretation of faith and religion presented a challenge both for the so-called Masaryk Slovaks and his critics. This paper focuses on a few reactions from selected authors, from the most famous follower of Masaryk's ideas on philosophy – s. Štúr – to the theologians J. Lajčiak and F. Jehlička. This particular issue – the interpretation of faith and religion in the lives of individuals as well as the whole of society – forms part of the presentation of Masaryk's ideas in a Slovak context.
