 Then, twenty-five years after in 1933, Pope Pius XI in a Papal Bull entitled “Ad maius religionis” divided Mindanao between the diocese of Zamboanga in the south and a new diocese that of Cagayan de Oro in the north, to which he appointed an American Jesuit, James Hayes, as the first bishop.The original territory of the diocese of Cagayan de Oro in 1933 included the provinces of Surigao, Agusan, Bukidnon, Misamis Oriental, Misamis Occidental, Lanao and the island of Camiguin.A series of divisions however, gradually reduced this territory.
