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.
