Faith development theory has evolved as a prominent theoretical perspective during the past three decades to explain different ways of relating to religious beliefs and worldviews. Recent revisions of the theory have elaborated on these characteristic ways as religious styles namely the fundamentalist, mutual, individuative-systemic, and dialogical. The present study developed an Urdu version of its principal measure, i.e., Faith Development Interview, to analyze twelve cases of Muslims of various religious affiliations within Islam in Pakistan. Four case studies representative of (...) each faith style are presented in detail. The cases are compared to analyze Islamic faith in terms of faith development theory and to understand fundamentalism in a Muslim context. The findings support faith development theory as a comprehensive paradigm to address the varieties of faith orientations in Islam. Implications for future research with larger samples in highly religious and collectivistic cultures are discussed. (shrink)
