Divine Liturgy of Saint James in the context of "Liturgy of Saint John Chrysostom"

The West Syriac Rite, also called the Syro-Antiochian Rite and the West Syrian Rite, is an Eastern Christian liturgical rite that employs the Divine Liturgy of Saint James in the West Syriac dialect. It is practiced in the Maronite Church, the Syriac Orthodox Church, the Syriac Catholic Church and various Malankara Churches of India (see the section on usage below). It is one of two main liturgical rites of Syriac Christianity, the other being the East Syriac Rite.It originated in the ancient Patriarchate of Antioch. It has more anaphora than any other rite.

Although the West Syriac liturgical tradition had always included many texts translated from Greek, this new influx of materials of Greek origin led to the emergence of two slightly different Syriac Orthodox traditions, that of Antioch, incorporating these new elements, and that of Tikrit, which did not incorporate it. It was essentially the Tikrit rite that was introduced into South India in the 18th and 19th century.

The Syro-Malankara Catholic Church, also known as the Malankara Syrian Catholic Church, is an Eastern Catholic sui iuris particular church that employs the West Syriac Rite and is in full communion with the worldwide Catholic Church possessing self-governance under the Code of Canons of the Eastern Churches. It is one of the major archiepiscopal churches of the Catholic Church. It is headed by Major Archbishop Baselios Cardinal Cleemis Catholicos of the Major Archdiocese of Trivandrum based in Kerala, India. With more than 1096 parishes, it is one of India's biggest church evangelical establishments.

The Malankara Syrian Catholic Church traces its origins to the missions of Thomas the Apostle in the 1st century. The Church employs the West Syriac Rite Divine Liturgy of Saint James. It is one of the two Eastern Catholic churches in India, the other being the Syro-Malabar Church which employs the East Syriac Rite liturgy.
