Input: Question: During what year did the independent West Syriac community develop into the Maronite Church? Passage:West Syriac liturgies represent one of the major strains in Syriac Christianity, the other being the East Syriac Rite, the liturgy of the Church of the East and its descendants. Distinct West Syriac liturgies developed following the Council of Chalcedon (451), which largely divided the Christian community in Antioch into Melkites, who supported the Emperor and the Council and adopted the Byzantine Rite, and the non-Chalcedonians, who rejected the council and developed an independent liturgy – the West Syriac Rite. An independent West Syriac community that grew around the monastery of Saint Maron eventually developed into the Maronite Church, which uses its own Maronite Rite. A variant of the West Syriac Rite, the Malankara Rite, developed in the Malankara Church of India and is still used in its descendant churches.
