This qualitative phenomenological study aimed to capture experiences of spiritual identity development in a purposive sample of South African adolescents, using semi-structured interviews and reflective writing exercises. Participants confirmed the prominence of religiosity and spirituality, as intertwined concepts central to their sense of purpose and identity. Consistent with the ideas expressed in psychosocial theories and lifespan development approaches, these adolescents valued the importance of choice when confronted with contradiction. They prioritized personal commitment and authenticity in their spiritual journeys toward finding a sense of self. It is clear that spiritual identity development unfolds as a lifelong process, driven by an interplay between cognitive development, psychosocial experiences, and the religiocultural context. The findings of this study reiterates that, as adolescents mature into emerging adulthood and their lives and meaning-making abilities become more complex, spirituality is critical in answering intricate questions about the self, others, and purpose of life.
