Liturgy is essential to the life of the Church. It is through liturgy that the Church expresses herself in the present day situation. The liturgy of the Syro-Malabar rite belongs to the Chaldean liturgical family. From around the 4 th C to the 16th C. the mass in the Syro-Malabr rite was celebrated in the Aramaic (East Syriac) language. But at the Daimper Synod in 1599, changes were made in the liturgy and the liturgy was made to conform to the Latin rite. But with the restoration of the liturgy that took place in 1962, the Liturgy of the Pre-Diamper began to be used. Now, the liturgy is being celebrated in Malayalam, the native language of Kerala. The Eucharistic Prayer of Addai and Mari is the one that is used in the Syro-Malabar Liturgy. The Eucharistic Prayer of Addai and Mari is one of the oldest Eucharistic prayers in the Catholic Church. The Eucharistic Liturgy has three forms: the most solemn form known as the Rasa, the solemn and the simple form. One of the special features of the Eucharist Prayer is the presence of four long prayers known as the Gehanta which are, according to many Eucharistic scholars, the closest forms of prayer to the Jewish Prayers over the meals.
