This article makes the case that Christian school counselors should be more directly engaged in student spiritual formation. To accomplish this aim, the historical context for the discussion is first explored, followed by a review of contemporary medical and psychological research associating a positive spirituality with healthy functioning across a variety of developmental domains. The argument is then situated within developmental theory and systems thinking as well as the Christian theological--philosophical writings of John Macmurray. Recommendations for improving Christian school counseling practice as they relate to student spiritual formation are included.
