is an ancient Church of India and it traces origin to as far back as A. D. 52 when St. Thomas one of the Disciples of Jesus Christ came to India and established Christianity in the South Western parts of the sub-continent.

St. Thomas Christians or the Indian Syrian Christians exist at present in different churches and denominations. But a major section of the parent body of St. Thomas Christians which has maintained its independent nature constitute The Orthodox Church under the Catholicate of the East on the Apostolic Throne of St. Thomas and the Malankara Metropolitan with Headquarters at Devalokam, Kerala in India. The Church, though modern in its vision and outlook, keeps the traditional oriental Orthodox faith and liturgy.

It accepts the first three Ecumenical Synods.The liturgy now in use is the translation of the liturgy adopted from the Antiochian Church. Earlier it had relationship with the Churches of Edessa, Tigris and Selucia. However, the liturgical rites are uniquely Indian. Today the Church uses liturgy in Malayalam, Syriac, Hindi, Kannada, German and English.

The Indian Orthodox diaspora in Ireland scattered over several cities in Ireland. Our church has parishes and congregations in Waterford, Cork, Sligo, Drogheda and Belfast (Northern Ireland).
