A study of the expansion of the early church from Pentecost continuing into the 20th century. Several questions will be considered, such as the following: Is the work of missions, as traditionally carried on, a thing of the past? Has the evangelical message, as traditionally preached to the nations, been in error? Have the methods of establishing churches with converted people been wrong? What are the present policies for the mission churches in assuming full responsibility for themselves? These and many more current trends and methodology will be covered.
