These articles delve into various facets of communication within multicultural contexts, exploring interfaith practices, cultural diversity, and social development in Indonesia. They emphasise the importance of ethical and inclusive communication for fostering interfaith relationships, as seen in Karl-Otto Apel’s approach to interreligious dialogue and the Hindu community’s interactions in Kutai Kartanegara. The studies also highlight the role of adaptive da’wah management in shaping youth development and addressing legal challenges, such as the fulfillment of child support rights post-divorce. Furthermore, they reflect on how cultural inculturation, identity negotiation, and the integration of social and religious values contribute to social resilience. Ultimately, the findings call for more effective social and legal reforms to promote justice, inclusivity, and equity in multicultural societies, ensuring that diverse communities can coexist harmoniously and sustainably.
