Professional psychologists may be asked about Christian counseling services and wonder how to best respond. Given the diversity of methods and worldviews that might be considered Christian counseling, it is important for psychologists to understand some of the major approaches used. Biblical counseling, pastoral counseling, Christian psychology, Christian ministry, and other approaches are described briefly, and in each case implications for professional psychologists are offered. Collaborative efforts are likely to be productive when interacting with certified pastoral counselors and Christian psychologists, and ministry approaches may provide supplemental resources for psychotherapy with Christian clients. Ethical issues are considered, and a 5-step model for responding to questions about Christian counseling is offered. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
