This comprehensive essay traces the 2,000-year evolution of godparents within Christian tradition—from early church sponsors ensuring the sincerity of converts, through medieval codification of spiritual kinship, to today’s flexible and sometimes secular interpretations of the role. It examines how godparenthood emerged from both theological and social needs, shaped by changes in doctrine, family structure, and cultural practice. Rooted in baptismal rites, godparents have long served as spiritual mentors and social connectors, influencing law, custom, and community in both religious and secular societies.
