The territory of the Diocese of Kochi holds deep spiritual heritage. It includes Kodungalloor, where St. Thomas the Apostle is believed to have landed in 52 CE, and early Christian centres such as Paloor, Maliankara and Kokkamangalam. Over the centuries it witnessed foundational events of Indian Christianity, including the controversial Synod of Diamper in 1599 and the Coonan Cross Oath of 1653.
The Synod of Veliyanad, presided over by Patriarch Ignatius Peter IV, divided the Malankara Church into seven dioceses, with Kochi originally comprising twenty-one parishes across Kochi State and British Malabar under its first Metropolitan, Karottu Veettil Semavoon Mar Dionysius. During the twentieth century the vast territory was progressively reorganised, giving rise to the Malabar, Kunnamkulam and Sulthan Bathery dioceses. Following the 1958 Supreme Court verdict, Metropolitan Paulose Mar Severios built the Zion Seminary at Koratty, which is now the diocesan headquarters. The diocese was guided by prominent spiritual leaders and several Catholicoi, including Baselios Geevarghese II and Baselios Augen I, and continues to contribute to the spiritual and cultural preservation of Malankara Orthodox history.
