The Syro-Malabar community at Mayur Vihar Phase III started Syro-Malabar Mass in 1998. Initially it had one Syro-Malabar Mass a month at St. Mary’s school. Fr. Sebastian Vadakumpadan served the community in the beginning. Fr. Joshy Vezhaparambil started to serve the community from 1998 and Mayur Vihar community had regular Sunday masses from 2001 onwards.
