The tradition of this place is as old as Christianity itself. In those days the faithful of Edathua region used to go for worship at the Niranam church found by St.thomas, the Apostle. And then to the Champakulam church established in A.D 427.With the advent of the Chempakassery regime at Ambalapuzha principality many christians migrated to Kuttanad from ancient christian centres like Kuravalangadu and Kudamaloor. As the number of the faithful increased the need for church at Edathua was dreamed.
The foundation stone of the Edathua Church was laid on september 29, 1810 on the feast of St. Michael, the Archangel with the canonical consent of Bishop Reymond, the vicar Apostolate of the Varapuzha Vicarate under the Kodungallor Archdiocese. As the number of parishioners and pilgrims increased it was decided to construct a more spacious church. So the construction of a church called “cemetery church” was begun in 1824, That church was blessed on May 6,1824(Medam 23,1015) by Dr.Luduvikose Marthini,the Co-adjuster bishop of varapuzha. The foundation stone of the present magnificant church was laid on November 15,1839(10th Vrichikam 1015) by the Co-adjutor bishop of varapuzha.
The madbhaha was completed in 1861.
