During the Parthian rule, St. Thomas visited Taxila. As a faithful disciple of Jesus Christ, he sowed the seed of Christianity in Taxila. After the ascension of Jesus Christ, the Disciples of Christ dispersed all around the world, and St. Thomas selected the Indian region to spread the Gospel. The whole story of St. Thomas is based on Gnostic record “Acts of Thomas” and few sources of Synoptic records. All these records narrate his visit in South India and North-West India (Pakistan).
