Batam, as one of Indonesia’s fastest-growing urban centers, presents a distinctive context for Christian Religious Education (CRE). The city’s multicultural and multireligious environment requires an educational approach that not only transmits doctrinal knowledge but also nurtures faith capable of engaging diversity. This study explores how the integration of Christian Religious Education and urban theology contributes to students’ holistic spiritual formation in Batam’s plural society. This research employed a qualitative descriptive approach, utilizing interviews, classroom observations, and document analysis in selected Christian schools in Batam. Data were analyzed thematically to identify patterns of pedagogical practices and theological perspectives that support faith formation amid cultural plurality. The findings indicate that effective Christian Religious Education in Batam emphasizes three core dimensions: theological contextualization of the Gospel within urban life, pedagogical strategies that respect cultural and religious diversity, and the cultivation of dialogue-based learning that fosters mutual understanding. Teachers who integrate theological reflection with practical pedagogy demonstrate higher effectiveness in nurturing students’ critical faith engagement. The study highlights the importance of linking urban theology with CRE to respond to the challenges of secularism, interreligious encounters, and cultural hybridity in Batam. Such an approach not only strengthens Christian identity but also promotes tolerance, empathy, and responsible citizenship. Integrating Christian Religious Education with urban theology provides a transformative model for nurturing faith in Batam’s multicultural context, offering valuable insights for religious education in other urban and plural settings across Indonesia.
