The “martyred” St. Thomas has existed since the Acts of Thomas, ca. 210 CE, in which he is executed by King Mazdai for social crimes and sorcery. The… - Ishwar Sharan

There is simply nothing Indian, much less South Indian, in the setting and ambiance of the Acts of Thomas. All internal evidence suggests Syria, Iraq and Persia – or Parthia as it was called in the first century CE – as the place where the drama of the Acts was played out to its preordained end, or to a kingdom on the edge of the Roman Empire – like Edessa itself – as there are strong Greco-Roman influences in the text, India as a specific place and Gundaphorus and Misdaeus-Mazdai as Indian kings appear to be literary devices used by Bardesanes to give credibility to the unconventional religious theme of the book.

Both Rufinus and Socrates would have known the Greek version of the Acts which was made immediately after the Syriac text was written (if it wasn’t the other way round as some scholars believe). They would also have known the testimony of Ephraim, Gregory, Ambrose and Jerome for St. Thomas in India. Yet Rufinus and Socrates both declare that St. Thomas went to Parthia.

And finally there is Luz Church, the first church the Portuguese would build in Mylapore and possibly the oldest standing Portuguese church on the Tamil coastline. It, too, is built on temple ruins, according to Archaeological Survey of India records, and was raised in 1516 by the Franciscan missionary priest Pedro da Atongia. The Catholic fortnightly Madras Musings says, "But with the Portuguese only occasional visitors to this coast from 1509 and settlers only from 1522, the dates on the stone plaque and above the church's entrance seem more likely the date of the establishment of a shrine in the 'grove of Thomas' than the date of the surviving building." Yes, indeed – but the "grove of Thomas" once contained a "pool of Vishnu". What happened to it in 1516?
