The Diocese history of Auchi dates back to the latter part of the 19th century when the first Roman Catholic Missionaries arrived at Agenebode in the present Etsako East Local Government Area of Edo State. Although, evidences abound of earlier contacts of the Christian missionaries with the indigenes of Agenebode and environs, the officially recorded date for this is 1884 when catholic priests started visiting Agenebode and environs from their then headquarters in Lokoja.
