The Divine Liturgy of St. John Chrysostom: Orthodox Service Books - Number 1

The Divine Liturgy of Saint John Chrysostom is the most celebrated Divine Liturgy in the Byzantine Rite. It is attributed to Saint John Chrysostom, Archbishop of Constantinople in the 5th century. It reflects the work of the Cappadocian Fathers to both combat heresy and define Trinitarian theology for the Christian Church. The Liturgy of Saint John Chrysostom was probably the Divine Liturgy (or "Mass") used originally by the School of Antioch and was, therefore, most likely developed from West Syrian liturgical rites. In Constantinople, it was refined and beautified under John's guidance as Patriarch of Constantinople (398–404). Having become the liturgical form of the Church of Holy Wisdom, Hagia Sophia, it became over time the normative liturgical form in the churches within the Byzantine Empire. The two liturgical rites of Saint John Chrysostom and Saint Basil in the Byzantine Church became the norm by the end of the reign of Justinian I.
