The Church of the East was the earliest form of Christianity in India , as adopted by the St Thomas Christians of the Malabar region (present-day Kerala ) from at least the third century, and possibly much earlier.[ a] [ 2] This diversified into different churches over time. Later, from the 17th century, the Catholic and Eastern Orthodox Churches , and Protestant denominations were introduced, brought by European missionaries and colonisers.

^ By long-held tradition, Malabar Christianity began in 52 AD. Although not confirmable, this early date is a canonical belief for St Thomas Christians; nothing in historical sources rules out such an ancient beginning.[ 1]
