Issues regarding workplace spirituality have received increased attention in the organizational sciences. The implications of workplace spirituality for leadership theory research and practice make this a fast growing area of new research and inquiry by scholars. The purpose of this research was to test a dynamic relationship between spiritual leadership and spiritual wellbeing (i.e. a sense of calling and membership) and key organizational outcomes in a sample of emerging military leaders. Using structural equation modeling (SEM) results revealed a positive and significant relationship between spiritual leadership and several unit-level outcomes including organizational commitment and four measures of performance. These relationships were explained or mediated by spiritual well-being. Implications for research and practice are discussed.
