This article focuses on the problem of social interaction occurring in the process of communication among believers of two Christian religions: Catholicism and Evangelical Church. Both confessions are represented by the highlanders of Silesian Beskid, Southern part of Cieszyn Silesia. Historical and socio-cultural circumstances of this community with two religions were shaping regional identity, cultural identification and traditional norms of coexistence for several centuries. These values were treated by the whole local community as more important than local disagreements. This way idea of cultural community was supported. It is visible in the attitudes and behaviors in which tolerance and acceptance finally overcame local animosities based on religious divisions.
