Many difficulties had to be overcome in preserving religious identity given the constant attacks by the dominant culture. The Byzantine Rite follows the canon law of Orthodox, its own liturgical calendar and uses Oriental ceremonies. The Mass is that of Saint John Chrysostom, which is celebrated in the Greek language in solemn ceremonies and in the Albanian language in daily functions. The peculiarities of the Eastern rite are evident in sacred vestments, the veneration of holy icons as well as the Church's architecture.
