Calderwood Baptist Church has a very good relationship with Bishop Elias Taban of the Evangelical Presbyterian Church in Southern Sudan.

Sudan is the largest and one of the most diverse countries in Africa. A Comprehensive Peace Agreement was signed in 2005 ending over 50 years of conflict between North and South Sudan, which the UN estimates cost over 1.5million lives and created over 5million displaced people.

Bishop Taban was born in May1955 on the day in which war broke out in his province. Elias became a child soldier at the age of 13 before training to become a Civil Engineer. Bishop Taban has also gained an Advanced Diploma in Theology and founded EPC in 2003.

Since the end of the Civil War, Bishop Taban has made it his mission to share Jesus with his people. EPC have planted many churches across Southern Sudan and local evangelists work in areas of the country where churches have yet to be planted.

EPC also operate a number of businesses, which support the redevelopment of the country. These include construction, water-well drilling and agriculture. While these businesses support the development of the country and meet the needs of local people, all the profit from the businesses is then reinvested into services that EPC provide, which include schools, orphanages, health clinics and a 50-bed hospital.
