 Syro-malabar liturgy and theology 

Those who continued with East Syrian theological and liturgical tradition and stayed faithful to the Synod of Diamper are known as the Syro-Malabar Catholic Church in communion with the Catholic Church- from article

Syro-Malabar Catholic Church did not stay in ""east syrian theological tradition"". They embraced roman catholic theology.The old east syrian church and roman catholicism are aeons apart in many doctrines.

Present Syro-Malabar Church has no uniform liturgy. Some of its dioceses use a latinised form of liturgy and they are arguing for an indigenous indian liturgy. Crisis is brewing in this church over matter of liturgy. See this: http://www.rediff.com/news/sep/05kerala.htm"
