Fusion is an explanation of the assimilation program Nelson Searcy utilizes in his local church. It has many practical suggestions on how a congregation can be more effective at interacting with guests and engaging them outside the walls of the church facility. The book is all about function and encouraging the reader to be intentional about moving the first-time guest into fully engaged member of the church.
Fusion is not a book on ecclesiology. In fact, the greatest frustration I had with the book was the lack of clarity concerning what the responsibilities and privileges of church membership are for the individual. He does make the point very clear that membership is for believers, but it saddens me that such a point must be made in a book discussing how to appropriately assimilate people into the church. When a congregation lacks a clear understanding of the nature of the church any assimilation program will resort to pragmatism. How pragmatic were the first Christians in the establishment and building of the church?
In my congregation, we need to do a better job of listening to our membership. The systems that have been effective in the past are no longer working due to societal shifts. With this in mind, we will begin using some of the ideas presented in the book, but at the same time, we are developing and teaching a thorough ecclesiology in order to ensure our methodology is consistent with scripture.
