For centuries already, Serbian Orthodox Church (SOC) plays a vital role in preservation of not only religious, but also an ethnic Serbian identity in different parts of the world where congregations of this religious community can be found. Although the majority of SOC members inhabit Balkan Peninsula, with the migration of ethnic Serbs to different parts of the world, the community started establishing its local branches in different parts of Europe, including Germany. Various local congregations of SOC in Germany are part of the Eparchy of Düsseldorf and all of Germany with one of them being church located in Kassel. SOC congregations, along-side family upbringing, usually play a noticeable role in preservation of ethnic identity, especially among the second-generation Serbs. As the children of Serbian labor immigrants, this generation faces the challenge of navigating dual identities - one rooted in their parents' homeland and the other shaped by their German surrounding. This research examines how the SOC serves as a vital institution in fostering a sense of belonging and cultural continuity. Relaying on ethnographic fieldwork, in-depth interviews with community members, just like analysis of church activities, study explores how religious practices, cultural celebrations and various communal events serve as key mechanism in maintaining Serbian identity.
