Who is the first Christianity in India?

The first recorded Christian in India is often considered to be St. Thomas the Apostle, who is believed to have arrived on the Malabar Coast around 52 AD. According to tradition, he preached the Gospel, established Christian communities, and was martyred in India. His missionary work is foundational to the Indian Christian community, particularly among the Syrian Christians of Kerala, who trace their roots back to his evangelistic efforts.
