It was the foreseen vision of His grace the Late Abraham Mar Thoma Metropolitan that “Every Marthomite is an evangelist”. The Marthoma Voluntary Evangelists Association (MTVEA) was formed in 1924. Parish mission or Edavaka Mission is the local chapter of Marthoma Voluntary Evangelistic Association. The main objective of the Edavaka Mission is to enable every parish member to accept Jesus Christ as their savior and to be fruitful as a Christian wherever they are. 
The St. Thomas Marthoma Church Edavaka Mission is hoping to engage the parishioners every year with the refreshing gospel of our Lord. The Edavaka Mission meetings are structured in a way that more importance is given for intercessory prayer, bible study and to share the testimony. Other planned programmes are house visits, keeping a prayer diary, organizing pariah convention etc.
