The Codex Gigas, the largest surviving medieval illuminated manuscript Liturgical only

Church Slavonic

црькъвьнословѣньскъ

The liturgical language of Slavic Eastern Orthodoxy, from Old Church Slavonic to its later national recensions.

Cyril and Methodius carried the liturgy to the Slavs in their own tongue. Church Slavonic, in its Russian, Serbian, and Bulgarian recensions, is still sung across Slavic Orthodoxy, and its translation fixed the pattern for vernacular worship in the East.

Prayers & Creeds in Its Traditions

  • Trisagion Prayers Orthodox — The opening prayers of Orthodox services and prayer rules, built around the thrice-holy hymn 'Holy God, Holy Mighty, Holy Immortal.'
