Marine Corps Reference Publication (MCRP) 6-12D, Devotional Field Book, is a resource for command religious programs in the Marine Corps. In addition to being a personal devotional guide for Marines and Sailors, it may be used in conducting divine services or lay led services. This MCRP was designed primarily to support those operations where limited printed resources are available for the command religious programs and is dedicated to the hope that it will lead others to the inexhaustible resources of God.
