Regarding the "House Church" movement, a term used to describe an independent group of Christians who gather in a home, Please begin by reading what appears may be a decent starting point for a definition of a House Church on Wikipedia: Wikipedia definition of a House Church Here are some reviews of books on the subject from different authors: Amazon.com Reviews of the Book "The Rabbit and the Elephant: Why Small Is the New Big for Today's Church" Amazon.com Reviews of the Book "Finding Organic Church: A Comprehensive Guide to Starting and Sustaining Authentic Christian Communities" 1. What can we in Baptist churches learn from this movement? Why do people leave traditional churches?

Hopefully this frames out two sets of questions that can be beneficial for our mutual learning on this topic.
