The Lausanne Theology and Education group (LTEG) was set up by the Executive of the Lausanne Committee for World Evangelization during its meeting in Berlin in September 1976. Its task is to promote theological reflection on issues related to world evangelization and, in particular, to explore the implications of the Lausanne Covenant. Charged with this responsibility, LTEG chose as the first topic for discussion the controversial "homogeneous unit principle," which has been developed by Fuller Seminary's School of World Mission.
The School of World Mission has had a very wide influence in recent years. Large numbers of mission theorists, mission executives, missionaries, pastors, and lay leaders have been challenged and stimulated by its philosophy of church growth. At the same time, some aspects of this philosophy have not escaped criticism. So during the present decade a number of books and articles have appeared, expounding and defending different points of view. The most important of them are listed in the bibliography.
