A theory is proposed to explain how religion/spirituality (R/S) is related to positive youth development and thriving. The concept of telos is employed to define thriving as continued growth through strength-based living that leads to contributing to one's communities and living out one's ethical ideals. Virtue development is proposed as a primary process by which R/S promotes thriving. Virtues are defined as hybrid personality units emerging when characteristic adaptations are given meaning by a transcendent narrative identity. R/S contributes to virtue formation through the ideological, social, and transcendent contexts embedded within religion by providing opportunities to grow both the characteristic adaptations and transcendent narrative identities necessary for virtue formation in youth and, ultimately, thriving. Implications for future research are discussed.
