The context and processes of an intervention intended to revitalize a church congregation's aspirations and practices as an empowered community during a period of rapid growth are described. Incorporating the principles of process‐oriented community and organization development with standard group techniques and interviewing, the first author, as an internal consultant, cooperated with the church members, board, and pastors in identifying both their needs and resources. The process and content results of the assessment demonstrated that spiritual, social, personal, and material needs and indigenous resources were successfully identified. The multiple methods of data collection enabled divergent groups in the congregation to participate and offered church members the opportunity to develop skills in assessment, problem solving, and decision making. With systematic feedback from the assessment the congregation subsequently specified courses of remedial action to promote a renewed sense of commitment to its core values; follow‐up over a year later showed that congregational development continued but with some retrenchment. The authors discuss the transferability of the findings, the role of an internal consultant, and the value of community and organization development for religious congregations.
