Spiritual character development constitutes a central dimension of holistic child development, influencing moral reasoning, identity formation, emotional regulation, and prosocial behavior. In contemporary societies characterized by rapid technological change, cultural pluralism, and declining communal value systems, concerns have emerged regarding the weakening of moral and spiritual foundations among children and adolescents. This meta-analysis examines the role of parents in the spiritual character development of their children through a synthesis of empirical, theoretical, and evaluative studies drawn from psychology, education, sociology, and family studies. Using a qualitative meta-synthesis design, peer-reviewed journal articles, books, dissertations, and international policy reports were systematically reviewed to identify dominant themes, convergences, contradictions, and contextual influences. Findings demonstrate that parents play a foundational and irreplaceable role in shaping children’s spiritual character through modeling, intentional value transmission, parenting style, emotional attachment, discipline practices, and family routines. While schools, religious institutions, and peers contribute to spiritual socialization, their effectiveness is significantly mediated by parental involvement and the home environment. However, parental influence is constrained by socioeconomic pressures, inconsistent parenting practices, digital media exposure, and weakened family structures. The study concludes that intentional, consistent, and relational parenting remains the most sustainable pathway for spiritual character formation. It recommends family-centered interventions, strengthened parental capacity-building, and coordinated collaboration between parents, educational institutions, and community organizations.
