The Syriac Orthodox Church, the Syriac Catholic Church, the Syriac Maronite Church of Antioch and the Syro-Malankara Catholic Church of the West Syriac Rite which is developed from the Antiochene Rite use a version of the Divine Liturgy of Saint James which differs substantially from its Byzantine Rite counterpart, most notably in being substantially shorter (it can be completed in under two hours, whereas the historic form of the Byzantine Rite liturgy prior to the revisions of St. Basil and St. John Chrysostom took more than four hours), and in that it can be used with more than eighty different anaphoras; the most commonly used are those of Mar Bar Salibi (which is the shortest), and that of St. James, which resembles that of the Byzantine Rite liturgy, and is mandated on certain occasions, such as major feasts, the consecration of churches, and the first liturgies offered by newly ordained priests. Due to the long isolation of the Saint Thomas Christians the rite of the Syro-Malankara Catholic Church shows some differences, so that this rite is called the Malankara Rite.
