Marine Corps Reference Publication (MCRP) 6-12A, "Religious Ministry Team Handbook," guides commanders, chaplains, Religious Program Specialists (RPs), and lay leaders in providing religious ministry and effective command religious programs (CRPs). It builds on the operational religious ministry principles in Marine Corps Warfighting Publication (MCWP) 6-12, "Religious Ministry Support in the US Marine Corps," and lessons learned from chaplains who ministered in war and peace. MCRP 6-12A clarifies the tasks and functions of the religious ministry team (RMT). It is a ready access to the tools RMTs need to perform their duties in today's expeditionary forces. Religious ministry in the Marine Corps is a combination of technique, common sense, art, experience, and caring about Marines and their families in garrison while being operationally ready at all times in every clime and place.
