That led later to western Christians giving the name "Nestorian Church" to the Church of the East where his teachings were deemed Orthodox and in line with its own teachings. Nestorius is revered as among three "Greek Teachers" of the Church (in addition to Diodorus of Tarsus and Theodore of Mopsuestia). The Church of the East's Eucharistic Service, which is known to be among the oldest in the world, incorporates prayers attributed to Nestorius himself.
