In the 1990s, Peter Wagner published The Healthy Church, a book describing several diseases that churches sometimes exhibit. Many of us who study churches have followed his lead and tried to name other diseases we have seen. Maybe one of these posts will speak to your church’s situation:
10 Church Diseases that Might be Afflicting Your Church
10 Infectious Diseases in the Church
10 Diseases of Church Small Groups
7 Potentially Deadly Church Sicknesses (by Thom Rainer)
If you name other diseases in churches, I’d love to hear about them!
