Book excerpt: First published in 1977 and now in its third edition, this book has been recognised as one of the most successful studies to be made of the impact of a Christian mission in Africa. Starting with a survey of the economy and society of Malawi in the mid ninetieth century, the book goes on to examine the home background to the Livingstonia Mission of the Free Church of Scotland and the influence of David Livingstone upon it. It then describes the failure of 'commerce and Christianity' around the south end of Lake Malawi and the subsequent positive response which the mission evoked among the people of Northern Malawi. African responses and the relationship between Christianity and politics dominate the second half of the book. Comprehensive reassessments are made of the origins of the Watch Tower movement; the growth of Christian independence and the character of interpolitical associations. This revised edition includes a new introduction, and up-dated bibliography, and some revised text.
