Malankara Mar Thoma Syrian Church in the context of "Divine Liturgy of Saint James"

A crozier or crosier (also known as a paterissa, pastoral staff, or bishop's staff) is a stylized staff that is a symbol of the governing office of a bishop or abbot and is carried by high-ranking prelates of Roman Catholic, Eastern Catholic, Eastern Orthodox, Oriental Orthodox, Malankara Mar Thoma Syrian Church, Church of South India and some Anglican, Lutheran, United Methodist and Pentecostal churches.

In Western Christianity the crozier typically takes the form of a shepherd's crook, a tool used to manage flocks of sheep and herds of goats. In Eastern Christianity, the crozier has two common forms: tau-shaped, with curved arms, surmounted by a small cross; or a pair of sculptured serpents or dragons curled back to face each other, with a small cross between them.

The Liturgy of Saint James is a form of Christian liturgy used by some Eastern Christians of the Byzantine rite and West Syriac Rite. It is developed from an ancient Egyptian form of the Basilean anaphoric family, and is influenced by the traditions of the rite of the Church of Jerusalem, as the Mystagogic Catecheses of Cyril of Jerusalem imply. It became the primary Divine Liturgy in the Church of Antioch and Church of Jerusalem in the early fifth century, soon becoming supplanted by the liturgies of Saint Basil and Saint John Chrysostom. It is still the principal liturgy of the Syriac Orthodox Church, the Malankara Orthodox Syrian Church, the Maronite Church, the Syriac Catholic Church, Syro-Malankara Catholic Church and other churches employing the West Syriac Rite. It is also occasionally used in the Eastern Orthodox Church and Melkite Catholic Church. The Malankara Mar Thoma Syrian Church uses a reformed variant of this liturgy, omitting intercession of saints and prayer for the dead.

The liturgy is attributed with the name of James the Just and patriarch among the Jewish Christians at Jerusalem.

The World Council of Churches (WCC) is a worldwide Christian inter-church organization founded in 1948 to work for the cause of ecumenism. Its full members today include the Assyrian Church of the East, most jurisdictions of the Eastern Orthodox Church (including the Ecumenical Patriarchate of Constantinople), the Oriental Orthodox Churches, the Union of Utrecht, the Lutheran World Federation, the Anglican Communion, the Mennonite churches, the World Methodist Council, the Baptist World Alliance, the World Communion of Reformed Churches, several Pentecostal churches, the Moravian Church, and the Malankara Mar Thoma Syrian Church. Notably, the Catholic Church is not a full member, although it sends delegates who have observer status to meetings.

The WCC describes itself as "a worldwide fellowship of 352 global, regional and sub-regional, national and local churches seeking unity, a common witness and Christian service". It has no head office as such, but its administrative centre is at the Ecumenical Centre in Geneva, Switzerland. The organization's members include denominations which claim to collectively represent over 600 million people across the world in more than 110 countries.

The mitre (Commonwealth English) or miter (American English; see spelling differences; both pronounced /ˈmaɪtər/ MY-tər; Greek: μίτρα, romanized: mítra, lit. 'headband') is a type of headgear now known as the traditional, ceremonial headdress of bishops and certain abbots in traditional Christianity. Mitres are worn in the Catholic Church, Malankara Orthodox Syrian Church (IOC), Malankara Syrian Orthodox Church (Jacobites), Eastern Orthodox Church, Oriental Orthodox Churches, the Anglican Communion, some Lutheran churches, for important ceremonies, by the Metropolitan of the Malankara Mar Thoma Syrian Church, and also, in the Catholic Church, all cardinals, whether or not bishops, and some Eastern Orthodox archpriests.

The Malankara Rite is the form of the West Syriac liturgical rite practiced by several churches of the Saint Thomas Christian community in Kerala, India. West Syriac liturgy was brought to India by the Syriac Orthodox Bishop of Jerusalem, Gregorios Abdal Jaleel, in 1665; in the following decades the Malankara Rite emerged as the liturgy of the Malankara Church, one of the two churches that evolved from the split in the Saint Thomas Christian community in the 17th century. Today it is practiced by the various churches that descend from the Malankara Church, namely the Jacobite Syrian Christian Church, the Malankara Orthodox Syrian Church (Indian Orthodox Church), the Syro-Malankara Catholic Church, Malankara Mar Thoma Syrian Church, and the Malabar Independent Syrian Church.

Among these, the Jacobite Syrian Christian Church, the Malankara Orthodox Syrian Church, the Syro-Malankara Catholic Church and the Malabar Independent Syrian Church preserve the traditional West Syriac liturgy, while the Malankara Mar Thoma Syrian Church follows a reformed liturgical tradition shaped partly by Anglican influences in the 19th century.
