A good opportunity to outline the problem mentioned in the title of this article is the publication of the sources presenting the process of canonization of blessed Dorota from Mątowy, already existent in German version and known to historians as such since 1978, but recently translated into Polish by the senior bishop of the Warmian archdiocese, Julian Wojtkowski, with the consent of Böhlau Verlag from Weimar. Thus, it is not the fact that the source was published that is the reason for this article, but rather that it has been made available in Polish, which has particular importance due to its source value for scientific research and promotion of the knowledge about Dorota from Mąty, a blessed recluse of the late Middle Ages. Another reason is associated with numerous unknown references regarding the townspeople of Grudziądz of the 14/15th c., who participated in the process of canonization of Dorota. In author’s opinion, the source material included in the files of the process of canonization, unnoticed by the contemporary historiography dedicated to medieval Grudziądz, may prove to be a very interesting and valuable for the research of the religious and cultural life of the city. This allows us to claim that quite a numerous group of Grudziądz townspeople enrolled in the religious atmosphere typical of medieval Pomesania, as they demonstrated faith in the miraculous intercession of blessed Dorota. Dorota – a recluse from Kwidzyn, was treated as a patron saint that could have helped those who suffered from numerous ailments or diseases, even in the face of death. In the discovered witness testimonies there is no skepticism regarding the feasibility of such a help, sometimes present in other such records. Among Grudziądz townspeople it was widely accepted that people should pray to blessed Dorota, expect her help and dedicate vows. Although the opinions of Kwidzyn townspeople testifying during the process may be perceived as inspired by the devotion of local clergy, in the case of Grudziądz townspeople and their testimonies we clearly observe the great fame of Dorota in the northern part of the Kulmerland and belief in her miraculous intercession and prophetic gift, which was expressed especially in the testimony by the Grudziądz commander.
