Dhanbad has Oriental Orthodox Churches. Christian missionaries arrived in today's Jharkhand in 1845. Pre-migration era

By the year 1765 Britishers were successful in their military mobilization to bring Santhal Pargana under British rule. After this conquest, the British colonial planters in India indentured tribal people of the Chota Nagpur Plateau region into Northeast India about 150 years ago for the purpose of being employed in the tea gardens industry as workers and came to be known as Tea tribes. These tribals were influenced by the Christian missionaries who came along with the British. These Christian missionaries worked for the improvement standard of living and providing education to the children of the tribals. Nearly 15 decades later missionaries from Germany left started their voyage to India in 1844 and reached Kolkata (formerly Calcutta) in 1845. These missionaries were initially heading for Mergui in Myanmar (formerly Burma) in view of preaching the Christian faith among the Karen people or in the areas located in the footsteps of the Himalayas. However, on meeting some people from Ranchi, they changed their plan and headed for Chhotanagpur and its main town, Ranchi. They reached Ranchi on 2 November 1845 and camped on, what is now known as, the 'Bethesda Ground' in Ranchi. Post-migration era
After India became independent, the missionaries who remained post independence, worked for the improvement standard of living and providing education to the children of the tribals. Evidently many of the tribals emerged as sportsmen especially in the game of hockey and football. Even the first Prime Minister of India, Dr. Jawaharlal Nehru, in his The Discovery of India acknowledges the contribution of the early missionaries for development of tribals dialect stating that 
even laboured at the dialects of the primitive hill and forest tribes...
