Here is the substance of the St. Thomas story: First, if he
existed he was a twin brother of Jesus which is unacceptable
because Jesus was the Only Son of God. Next, he could not have
preached Christianity in 52 AD because Christianity and the New
Testament came into existence only in the fourth century, after
the Council of Nicaea called by Roman Emperor Constantine in 325
AD. The first Christians came to India with the Syrian merchant
Thomas in 345 AD escaping persecution in Persia. Lastly, the
Namboothari Brahmins settled in Kerala only after the fourth
century AD, so could not have been converted by Apostle Thomas
in 52 AD using the Bible from three centuries later. – Dr. N.S.
Rajaram According to Christian leaders in India, the Apostle
Thomas came to India in 52 A.D., founded the Syrian Christian
Church, and was killed by the fanatical Brahmins in 72 A.D. His
followers built the St. Thomas Church near the site of his
martyrdom. Historians however say this apostle, even if he
existed, never came to India.
