From a popular standpoint, Christian Schwarz's book on natural church development is being accepted overwhelming, and also uncritically, by many pastors and church leaders. However, several scholars are raising major concerns about the research methodology employed by Schwarz. Drs John Ellas and Flavil Yeakley carefully point out what they describe as the “pseudo-science” used for the underlying research base described in Schwarz’s book.
