Church Slavonic

Church Slavonic is the traditional liturgical language of the Orthodox Churches and Eastern Catholic Churches in the Slavic-speaking countries. The oldest form of the language was created towards the end of the ninth century during the Slavic mission by the two brothers Cyril and Methodius. However, this Old Church Slavonic only makes up a small part of the manuscript tradition, as the majority of Church Slavonic literature was influenced by local vernacular idioms, resulting in different versions of Church Slavonic.
