This article examines the origin, history, profile and mission of the Roman Catholic weekly Dzwon Niedzielny [Sunday Bell] published in Krakow in 1925–1939. The methodology of critical analysis of historical sources and qualitative analysis of press studies has been used to assess whether the magazine was successful in carrying out its program. On the linguistic level, the corpus of core article headlines from a total of 765 issues has been analyzed (with the help of the text analysis tool corpusomat.pl) to identify keywords, collocations, characteristic vocabulary and construct a word frequency table. The results indicate that the editors by and large stuck to their declared goals and objectives. The mission statement from the magazine's earliest phase was still very much in evidence in what it published years later. The editors of the Dzwon Niedzielny never wavered from their main goal which was to educate the public in spirit of Roman Catholicism, patriotism and communal responsibility.
