This book is the result of a socio-theological analysis of the substantial membership growth of the Christian and Missionary Alliance--C&MA--in Lima, Peru, since 1973. The C&MA is a Protestant Christian denomination with worldwide work in North America, Latin America, Africa, Asia, and, recently, Europe. The focus here is on its work in Lima, Peru. The C&MA started its work in Lima in 1957, and by 1973 had 120 members. Today's membership has grown to about 60,000 with heterogeneous social backgrounds. It is this substantial membership growth, starting at the end of 1973, that has motivated the primary research question: What are the main conditioning factors that have led to the substantial growth of the C&MA in Lima since 1973?
