This chapter focuses on three major areas of investigation into the role of religion and spirituality in older people’s lives: age differences in the nature of religious and spiritual belief and practice; health benefits that accrue to older people who profess a religious faith and engage in spiritual activities; and influences on social and intergenerational relationships and support resulting from membership of a faith tradition. Social gerontology’s recent concern with religion and spirituality in later life has had a relatively limited impact on theorizing about aging and social relationships. Hinduism is also widely regarded as an age-friendly religion, which ascribes a distinct more mature stage of being to the last stages of life, in preparation for the transition to a new life beyond death. The chapter concludes with a stress on the importance of conducting research on religion, spirituality, and aging in non-Western and non-Christian cultures.
