Devotees from other states are the main contributors to this Church feast. The feast, known as "Edathua Perunnal", helped Edathua to develop as one of the most important commercial centers in Kuttanad region. During the feast family members from outside Edathua, especially from the southern Kollam, Trivandrum side of Kerala and Kanyakumari District of Tamil Nadu, come and visit their relatives. During the 10-day feast, many devotees stay and cook food in the church premises and take part in ritual bathing in the river in front of the church. The church is colorfully illuminated, and there is a fireworks display.
