Missiology Made Simple

A collection of essays on Missiology for missionaries

Missiology is said to be the mother of all theology; for it is out of the gospel’s engagement with culture that theology develops. Without proper missiology, there is a good chance that Christianity will be looked upon as a foreign religion. This collection of essays on missiology represents the collective wisdom of two missiologists, Dr. Gary Fujino and Dr. Michael T. Cooper. Based on their life-long learning as missionaries and missiologists, these essays will provide foundational concepts for being a successful missionary.

Gary and Michael have been doing missiology together for 20 years. They bring more than 60 years of missions experience as field missionaries and academics who have been equipping missionaries around the world. Their missiological collaboration began on the campus of Trinity Evangelical Divinity School as they embarked on their doctoral studies at the turn of the millennium. Many hours were spent working through missiological issues raised by Paul Hiebert, Robert Priest, Tite Tienou, and Harold Netland. Gary and Michael’s passion has always been in making missiology accessible to missionaries.
