Gilanians and Bactrians have any intercourse with strangers". The Sasanians also proved rather tolerant of the Christian faith until the persecution by the Zoroastrian priest Kartir under Bahram II (276–93 AD). Further persecutions seem to have taken place under Shapur II (310–379) and Yazdegerd II (438–457), with events in 338 having brought significant damage to the faith. India (1st century AD) According to Eusebius' record, the apostles Thomas and Bartholomew were assigned to Parthia (modern Iran) and India. By the time of the establishment of the Second Persian Empire (AD 226), there were bishops of the Church of the East in northwest India, Afghanistan and Baluchistan (including parts of Iran, Afghanistan, and Pakistan), with laymen and clergy alike engaging in missionary activity. An early third-century Syriac work known as the Acts of Thomas connects the apostle's Indian ministry with two kings, one in the north and the other in the south. According to the Acts, Thomas was at first reluctant to accept this mission, but the Lord appeared to him in a night vision and compelled him to accompany an Indian merchant, Abbanes (or Habban), to his native place in northwest India.

Thomas thereafter went south to Kerala and baptized the natives, whose descendants form the Saint Thomas Christians or the Syrian Malabar Nasranis. Piecing together the various traditions, the story suggests that Thomas left northwest India when invasion threatened, and traveled by vessel to the Malabar Coast along the southwestern coast of the Indian continent, possibly visiting southeast Arabia and Socotra en route, and landing at the former flourishing port of Muziris on an island near Cochin in 52. From there he preached the gospel throughout the Malabar Coast. The various Churches he founded were located mainly on the Periyar River and its tributaries and along the coast. He preached to all classes of people and had about 170 converts, including members of the four principal castes. Later, stone crosses were erected at the places where churches were founded, and they became pilgrimage centres. In accordance with apostolic custom, Thomas ordained teachers and leaders or elders, who were reported to be the earliest ministry of the Malabar church. Thomas next proceeded overland to the Coromandel Coast in southeastern India, and ministered
