The Jacobite Syrian Christian Church is one of the oldest Christian communities in the world. Its history dates back to the time of St. Thomas the Apostle, who is believed to have arrived in India in AD 52 to spread the message of Jesus Christ. Over the centuries, the faith grew and took root in different parts of India, especially in Kerala. As the community expanded, members moved to other states, including Karnataka, leading to the formation of the Jacobite Syrian Christian Church Bangalore Diocese.

The Bangalore Diocese was established to bring together the faithful living in Karnataka under one spiritual leadership. This diocese falls under the Holy Apostolic See of Antioch and All the East, which is the spiritual head of the worldwide Jacobite Syrian Christian Church. The diocese works towards maintaining the rich traditions, customs, and liturgical practices handed down through generations.
