The Diocese of Alleppey was erected by the 1952 Papal Bull "Ea Redemptoris Verba" of Pope Pius XII that divided the northern territory of the old Cochin Diocese at the Kuthiathodu Canal Line. The territory to the north of that line now belongs to the Cochin Diocese and the territory to the south to the Diocese of Alleppey. The executorial Decree of 8 September 1952 assigned to the Diocese of Alleppey and Cochin respectively a supplementary personal jurisdiction over certain parishes in the territory of the other. This Decree was approved by the Sacred Congregation for the Propagation of the Faith on 24 September 1952 and became effective on 11 October 1952. The boundaries are defined as: to the north, the Kuthiathodu Canal Line; to the south, a straight line from the curve of the Pampa River at Viyapuram to the Arabian Sea through Thottappally; to the east, a line along the middle of the Vembanadu Lake continued to the south of the Pallathuruthy Canal to Viyapuram; to the west, the Arabian Sea. The area assigned to the Diocese comprises roughly the area of the Jesuit Mission of St. Andre of Muteret. The Jesuit started mission work among the St Thomas Christian in this area about 1570. One of the most influential Jesuit missionaries who worked in this area was Fr. Giacomo Fenicio, an Italian who was Vicar of St Andrew’s Church at Arthunkal, from 1584 to 1602 and again from 1619 until his death in 1632. He was a pioneer in Indology. A century of intense mission work of the Jesuits increased the size of Christian community from Cochin to Purakkad and built several churches, notable among them being St. Andrew’s Arthukal. St. Michael’s Kattor, St. Thomas Thumpoly and St. George’s Manakodam. A few other churches built during this period were destroyed by wars or by sea erosion. After the Schism of the Coonan Cross, the St. Thomas Christians of the Mission of St. Andre were reconciled to Rome by Msgr. Giuseppe Sebastiani during his second tour of Malabar in 1662. Even after the capture of Cochin by the Dutch, the Jesuits continued to look after the Christians of this area until the middle of the 18th century. The Mission was then taken over by the Carmelite Missionaries and remained under the Vicariate of Verapoly until the restoration of the old Cochin diocese in 1886. In 1570 Jesuit missionaries started to work in the area. Five churches were built:
