This study explores the integration of Christian values in multicultural classrooms, focusing on the challenges and opportunities faced by Christian educational institutions in Batam, Indonesia. As a rapidly developing urban center, Batam exemplifies Indonesia’s pluralistic society, where religious and cultural diversity shape daily educational experiences. Christian schools in this context are tasked with preserving their theological identity while promoting inclusivity and religious tolerance among students from various faith backgrounds. Employing a systematic literature review (SLR) guided by the PRISMA framework, this research synthesizes scholarly works published between 2015 and 2024. Literature was gathered from international and Indonesian databases such as ERIC, JSTOR, ProQuest, ATLA Religion Database, Garuda, and Neliti. The analysis included 86 relevant studies focusing on Christian education, multicultural pedagogy, religious tolerance, and faith identity development. The thematic findings reveal four core areas: strategies for integrating Christian values in diverse classrooms, challenges in balancing religious identity with inclusivity, best practices from global and local contexts, and theological-pedagogical frameworks supporting inclusive Christian education. In Batam, successful models involve contextualized curricula, interfaith dialogue, service-learning projects, and holistic mentorship. The study highlights the need for professional development programs in cultural competency and the creation of institutional policies that foster both faith formation and intercultural respect. While offering theoretical contributions to religious pedagogy and multicultural education, this research also provides practical guidelines for educators and administrators. Limitations include the reliance on secondary data, suggesting a need for future empirical research in classroom settings. Ultimately, the study proposes a balanced educational approach that honors Christian faith while nurturing social harmony.
