A History of the Church in Africa by Bengt Sundkler and Christopher Steed is reviewed. In 1900 the Christian population of Africa was estimated at 4 million out of a total of 118 million people. Roman Catholics were estimated at 1 million, Protestants at 1 million and Coptic-Orthodox at 2 million. This picture has changed radically. Today Christians amount to some 351 million out of 770 million. Any estimate of the growth of the Christian Church in Africa in the last 100 years is spectacular. In the book under review Sundkler (1909-95), the eminent Lutheran missionary bishop and church historian, has put flesh on these bare statistics in this his magnum opus.
