It comprises Sharpeville, Vereeniging, Boipatong, Vanderbijlpark, Sebokeng and the southern side of the city of Johannesburg.
The diocese is the area between the Vaal Triangle—where Sharpeville, Vereeniging, Boipatong, Vanderbijlpark and Sebokeng are found—and the southern side of the city of Johannesburg.
The diocese is small in size, being only 80 kilometres (50 mi) long and half that wide, but rapid urbanisation has resulted in significant growth in parishes.
One of the latest new congregations worships in French and aims to welcome refugees from the Congo and other Francophone African countries.
Locally, the diocese enjoys a close relationship with the Anglican Diocese of St Mark the Evangelist, with youth from Christ Church, Polokwane, and elsewhere, attending the "A re roriseng ("Let us worship") conference each year in Rosettenville.
