This study investigated the role of spirituality and religion in supporting purpose during adolescence. Two case studies of adolescents who were coded as purposeful in the religious and/or spiritual domain as part of a larger study at the Stanford Centre on Adolescence were analysed and discussed. The results showed religion and spirituality as overlapping domains with authenticity to self as expressed though spirituality as a distinguishing factor between the two cases. Authenticity fosters one of the key elements of purpose--meaningfulness to the self--but only if done with equal attention to the world beyond the self.
