[Objective] This study aims to explore the characteristics and tasks of old age within a super-aged society, proposing Christian educational strategies that enable the elderly to play meaningful roles in the church community. This exploration incorporates insights from social developmental psychology and theological perspectives on vocation and interdependence in later life. [Contents] Moving beyond a limited view of the elderly as merely wise figures or passive recipients of pastoral care, this study highlights the unique vocation and value of this life stage. Drawing on Joan Erikson’s (1997) and Joyce Ann Mercer’s (2017) work, Erikson provides a fresh perspective on the unique tasks and realities of old age, while Mercer expands our understanding of aging and vocation in later life. These perspectives support a vision of the church as an intergenerational community fostering growth and deeper relationships with God. [Conclusions] As a results of the study, a broader understanding of old age contributes to enhancing the richness and purpose of life in later years. Church education should emphasize that the elderly continue to play essential roles within God’s calling. Third, a deeper understanding of vocation in old age plays a key role in transforming the church into a faith community where all generations grow together and form deeper relationships with God.
