[4] The Church now has two dioceses, one in Colombo (covering the Western, Southern, Eastern, Northern and Uva provinces and Ratnapura, Nuwara Eliya and Puttalam districts) and the other in Kurunegala (covering Kurunegala, Kandy, Matale and Kegalla, Anuradapura, Polonnaruwa, districts).

The missionaries who arrived in Galle started to establish schools in order to uplift the education of the natives and to spread the Christian religion.

The SPG helped Bishop James Chapman establish the College of Saint Thomas the Apostle in Mutwal, which opened on 3 February 1851.

The schools are independently and privately managed by the CMS governing body headed by the bishops of the church, while some schools like Trinity College Kandy have adopted a board of governors under the patronage of the Bishop of Kurunegala.

Prime ministers D. S. Senanayake, Dudley Senanayake, Wijayananda Dahanayake and S. W. R. D. Bandaranaike were past pupils of S. Thomas' College, Mount Lavinia as well as Leslie Goonewardene and N. M. Perera, founders of Ceylon's first political party.

The music for parts of this hymn was composed in 1950 by the leading Sri Lankan folk musician Deva Suriya Sena.
