A.C.K Immanuel Church Weithaga is arguably the oldest church in our Diocese and only second in the larger Mt. Kenya region to A.C.K St. Paul’s mother church Kabete. The mother church in Kabete was started in 1900 by the Leaky family while the Weithaga church was started in 1903 by The Rev. Wallace Arthur McGregor commonly and locally called Mangereka. The foundation stone of this church was laid on Feb 2nd 1935 by the Bishop of Mombasa then Rt. Rev. R.S Heywood. The Church has since then gone through several renovations and extensions to what it is today. Weithaga pastorate has been served by more than 110 Vicars from 1903 to date. The first Vicar was The Rev. Arthur Wallace McGregor who served from 1903-1925 the longest so far. The current Vicar is the Ven. John Ndegwa Maina who is the Archdeacon of Weithaga and the Vicar General of the Diocese. Weithaga church has been served by more than 110 clergymen so far. The interesting thing about the church is that out of all those who have served there, seven of them have become Bishops in the Anglican Church as shown below;
