The Indian Orthodox Syrian Church was founded by St. Thomas, one of the twelve apostles of Jesus Christ, who came to India in A.D. 52. It adopted East Syrian language and liturgies in the fourth century, becoming known as Syrian Christians. The church faced splits during interactions with Roman Catholic, Protestant, and Antiochene influences. The Catholicate was established in 1912, solidifying its leadership structure.

The concept of the “Throne of St. Thomas” stems from biblical passages (Matthew 19:28, Luke 22:28), affirming apostolic authority. The church, with 2.5 million members globally, follows West Syrian liturgy and aligns with Oriental and Eastern Orthodox, Roman Catholic, and Protestant Churches.

The current head is H.H. Baselios Marthoma Mathews III, residing at the Catholicate Palace in Kottayam, Kerala. The church comprises 30 dioceses, each led by a bishop, emphasizing both administrative and spiritual roles.
