The geo-political zone of which is the Diocese of Amichi became conscious of the missionary tread in 1909 with a group of inquisitive and enthusiastic citizens of Amichi on expeditionary venture to C.M.S. Headquarters at St. Mary’s C.M.S. Church Uruagu Nnewi. The ream was led by the earliest convert Okafor Aguzie (Later baptized, Abraham).

These pioneer converts led by Okafor Aguzie their leader who was baptized Abraham, were Okoli Ezike baptized Peter Ezike, Okeke Okonkwo baptized James Okonkwo, Enekebe Onyekonwu baptized Richard Igwebuike and Nwike Onyeorie baptized Joseph Onyeorie. Others who were not yet baptized then were Umeanulude Ezike-Igbokwe, Ajajiofor Nzukwe, Okwumuo Okafor and two women Akuezuonu and Nwayorie.

By 1911 the resident evangelists from St. Mary’s Uruagu had begun to operate in Amichi and the real evangelism had begun throughout Amichi and its environs. From Amichi the gospel spread to Osumenyi, Ezinfite, Akwaihedi, Utuh, Ebenator, Ekwulumili, Unubi and Ogbodi.

All the churches in this geo-political zone remained administered from St. Mary’s C.M.S. Church at Uruagu Nnewi until 1940 when St. Simon church Nnobi became a district and took over the administration from her.

In 1957, St. Andrew’s Church Amichi was made a Parish and other churches in the environ came under the umbrella of the Parish and continued so till the year 1962. When St. Andrew’s Church, Amichi because a district of its own in 1962, it ceased to be under the administration of St. Simon’s Church district Nnobi. While the Churches in the following communities – Osumenyi, Ezinifite, Ebenator, Utuh, Akwaihedi, Ekwulumili, Unubi and Ogbodi remained under St. Andrew’s Church district, St. James Church, Azigbo was still under Nnobi district.

Until now, the Diocese on the Niger continued to be the administrative headquarters of all churches under St. Mary’s Church Uruagu Nnewi. St. Andrew’s Church Amichi, St. Stephen’s Church Osumenyi, St. Simon’s Church Ezinifite, St. Andrew’s Church Ebenator, Holy Trinity Church Utuh, Immanuel Church Ekwulumili, Ebenezer Church Unubi, Immanuel church Akwaihedi St. James Church Azigbo, All Saint’s Ogbodi and many more medium and smaller churches in the present geo-political zone of Nnewi South Local Government Area, Ekwusigo Local Government Area and Nnewi North Local Government Area.

As the Anglican Missions in Nigeria continued to grow and expand, with the Niger Diocese now being too unwieldy to be administered by the Bishop who is the Bishop on the Niger, as well as the Archbishop of the province of the Niger, it became obvious that hitherto Niger Diocese would require more Dioceses. First Enugu Diocese was carved out followed by Awka and then Nnewi Diocese in February 1996. Thus bringing Nnewi, Amichi and Ihiala Archdeaconries under the administration of Nnewi Diocese with its first Bishop as the Rt. Revd Dr G.I.N. Okpala (J.P).

When Amichi District was made Archdeaconry on 14^th February 1992 that was before the creation of Nnewi Diocese, the following parishes came under its jurisdiction: St. Andrew’s Parish Amichi, St. Stephen’s Parish Osumenyi, St. Simon’s Parish Ezinifite, St. James Parish Azigbo, Immanuel Church Parish Ekwulumili and Ebenezer Church Parish Unubi.
