Did St. Thomas establish Christianity in India
One of the Apostles of Christ, St Thomas whose remains are buried in Madras and St Bartholomew, had visited India and established Christianity here in the early years of the Christian Era.
“St. Thomas never came to South India” as per Pope
When Armenian Christians visited that place in Madras, all they found was ruined Hindu temples and samadhi of a Hindu Yogi. The Portuguese later converted it into St. Thomas Church in 16th century.
