This article introduces ten volumes on church life in Sudan. While the authors are from within the church, their first purpose is not to give a fair as possible view on the story as a whole. It is evident that the account in these books has a purpose beyond the dispassionate recounting of history. Perversely to its opponents, the Sudanese church often demonstrated courage under persecution and has even grown in the face of persecution. The reaction of the Sudanese Christians to the systematic cruelty they experienced is one of the great untold stories of the church in the twentieth century.
