History of Indian Orthodox Church

Administration
The Church has its head quarters at Kottayam, Kerala. The present head of the Indian Orthodox church is H.H. Baselius Mar Thoma Didymos I. The official title of the head of the Church is "the Catholicos of the East seated on the throne of St Thomas and the Malankara Metropolitan".
The Church is ruled and governed by the Church Constitution of 1934. True to the orthodox Christian tradition, the Indian Orthodox Church employs an administrative system which is a perfect blend of episcopacy and democracy.

The Church is divided into 25 dioceses with a bishop heading each diocese. The Malankara Syrian Association is the parliament of the Church which is a body of bishops and elected laity and clergy representatives from all the parishes. This Association meets on special occasions to take important decisions pertaining to the entire church.
The Association also elects a Managing Committee for carrying out administrative activities on behalf of the Association. The number of laity members of this committee is double that of the clergy, which indicates the participative nature of laity in church matters. The Episcopal Synod comprising of all the Bishops of the church is the authority regarding Faith, Order and Discipline. The Synod is also responsible to install the Catholicos designated by the Association.
Faith and Liturgy
The Church, though modern in its vision and outlook, keeps the traditional Orthodox faith and liturgy. It accepts the first three Ecumenical Synods. In earlier days, the liturgy used by the Church was adopted from the Persian Church, which had to be abandoned at the Portuguese compulsion at the end of 16 th century. The liturgy now in use is the translation of the Syrian liturgy adopted from the Antiochian Orthodox Church in the 17th century. Today the Church uses Malayalam as liturgical language in Kerala, respective local languages in other parts of India and English in outside India.
The Indian Orthodox community inherited many aspects of Indian civilization and they are as any other member of any other community in India, in their customs, manners and life style.
History
Since the Old Testament times Kerala had trade relations with West Asia. These trade routes later enabled Christianity to reach Kerala that the Apostle Thomas preached the Gospel to the locals (which included Jewish settlers in Kerala), baptized many, ordained priests and founded seven churches. These seven villages became epicenters of Indian Christianity and other parishes started evolving from these seven mother parishes.
