The purpose to this paper is to explore the relationship between teachers' perceived spiritual leadership and organizational commitment. A survey was conducted to collect data from a sample of 2,094 teachers from 117 primary and secondary schools in Hong Kong. Questionnaire developed by Fry et al. (2005; Fry, 2003; Karadag, 2009) was used to measure teachers' perceived spiritual leadership and spiritual survival in their schools. Eighteen items were used to measure the three factors of teachers' organizational commitment: affective commitment, continuance commitment, and normative commitment (Meyer, Allen, & Smith, 1993). The analyses were conducted using multilevel confirmatory factor analysis (MLCFA) and multilevel structural equation modeling (MLSEM). The current study has illustrated how membership and meaning/calling play a mediating role between spiritual leadership and organizational outcomes. It has shown that the influence of spiritual leadership on membership is apparently stronger at the school level than is it at the teacher level. This reflects, to an extent, the observation that qualities operate at both individual and organizational levels. It also reflects the call for all members in an organization to engage in a spiritual journey – a journey of transformation to become a less ego-centered and more other-centered person (Fry and Altman, 2013, p. 69).
