The conversion of Vedha Muthu has an historical perspective. Before
British supremacy was established in the region it had been part of the Vijayanagara Empire, whose appointed
Nayaks, (governors), had restricted the life of the members of Vedha Muthu's Nadar caste, regardless of status, and denied them access to the
Thiruchendur Murugan Temple. Consequently, many Nadar's considered the arrival of the British as an opportunity to remove this discrimination, and had become receptive to Christianity. In 1823, after performing Christian conversions at
Sathankulam, the Rev. C T E Rhenius, (the first
Church Mission Society missionary in India), visited Solaikudiyiruppu. Through the encouragement and preaching of Rhenius, Vedha Muthu converted and was baptised with the new name,
Velu Muthu, becoming the village's first Protestant Christian. Rhenius converted many in Solaikudiyiruppu, and by 1825 had persuaded Vedha Muthu and his fellow converts to build a church. After the mysterious death of the Nadar Christians' leader Chinnamuth Sundaranandam David, Rev. Rhenius looked for another to share missionary work, and turned to Vedha Muthu to take the place of Sundaranandam David, whereupon Vedha Muthu joined an initiative to establish a Christian satellite village at Neduvillai. In 1830, Neduvillai's name was changed to
Megnanapuram, meaning a "Place of True Wisdom". ==Schism and reconciliation==
