Healthy Churches are Growing Churches. That is the premise of Robert Warren's Healthy Churches' Handbook. Using a similar approach to Christian Schwarz's Natural Church Development (NCD), Warren suggests that healthy churches will be strong in seven values, goals and characteristics (as opposed to eight activities in NCD).
These are: energised by faith; outward-looking focus; seeks to find what God wants; faces the cost of change and growth; operates as a community; makes room for all; and does a few things and does them well.
The second part of the book contains practical material to help churches become more healthy, including a questionnaire which enables you to develop a profile of your church and to see which areas need the most work.
Robert Warren is an experienced mission-oriented priest (he was team rector of St Thomas, Crookes at the time of the Nine O'Clock Service) and much of the material was developed while he was involved with the Church of England's Springboard project.
