The West Syriac Rite is the liturgy of a communion that history scattered and worship held together. After the Council of Chalcedon in 451 the church of the Syriac-speaking East divided over the council's definition, and the party that rejected it, given hierarchy and endurance by the tireless sixth-century bishop Jacob Baradaeus, became the Syriac Orthodox Church, with the West Syriac liturgy as its bond.
Under Islamic rule the community persisted as a people of its rite, its patriarch of Antioch residing in a succession of Mesopotamian monasteries, its scholarship flowering in figures such as Bar Hebraeus, and its liturgy absorbing Arabic alongside Syriac while never surrendering the older tongue. The rite's most remarkable journey was eastward.
The ancient Christians of Kerala, who traced their foundation to the apostle Thomas, entered communion with the Syriac Orthodox patriarchate in the seventeenth century after their revolt against Portuguese Latinisation, and the West Syriac liturgy became the worship of the Malankara churches, celebrated today by millions of Indians in Syriac and Malayalam.
A separate branch, the Maronite Church of Lebanon, kept its own form of the same Antiochene-Syriac inheritance in communion with Rome, with Latin borrowings layered over the Syriac base. One rite therefore serves churches in five communions across three continents, a liturgical family tree whose trunk is the prayer of ancient Jerusalem and Antioch.
