The paper is devoted to the analysis of the onymic cultural tradition of the believers of Judaism and Christianity in Podlasie. The author also discusses how the coexistence and integration of various cultural elements is reflected in the anthroponymy of both communities in the region. Stemming from Judaism, Christianity incorporated many elements of Jewish culture, which can be observed in various spheres. From the onymic perspective, it regards mostly biblical names from the Old Testament, which are included in the repertoires of names of both Jewish and Christian inhabitants (Abraham - Abraham, Beniamin - Benjamin, Jakub - Jacob, Józef - Joseph, Szymon - Simon; Anna - Anna, Elżbieta - Elisabeth, Maria - Mary etc.). In Podlasie, from the 15th c. up to the 20th c., the coexistence and mutual influences of both cultures contributed to diminishing differences in the onymic sphere, which is reflected in the presence of identical basic forms of biblical names, and the short forms derived from these names. The syncretism is even more apparent in the surnames of Podlasie inhabitants derived from the same anthroponymic, toponymic, or appellative bases by means of identical derivational suffixes.
