The Malankara Orthodox Syrian Church (MOSC) also known as the Indian Orthodox Church (IOC) or simply as the Malankara Church, is an autocephalous Oriental Orthodox church headquartered in Devalokam, near Kottayam, India. The church serves India's Saint Thomas Christian (also known as Nasrani) population. According to tradition, these communities originated in the missions of Thomas the Apostle in the 1st century (circa 52 AD). It employs the Malankara Rite, an Indian form of the West Syriac liturgical rite.
