This study showed the nexus between state and Nahdlatul Ulama (NU), being the mainstream Islamic group addressing political ideology beyond Pancasila. The transnational influence views religion as an ideology, not faith, resulting in the different nation’s elites response. Furthermore, the government failed to formalise the relationship by endorsing NU to take concrete measures in the area. This study demonstrated how Indonesian religious organisations could maintain stability. The post-Suharto era evinced the special relationship between the state and the largest Muslim organisation, (...) helping the government to defuse militant doctrines. Furthermore, this study defied the secularisation theories to set aside the religion’s role in adapting national democracy or social development. The findings indicated that the compromising politicking religion could strengthen the national identity and ideology shield of external infiltration doctrine. Contribution: This article examines the problem of contemporary nationalism post-Suharto and the variety of potential disintegration. Indeed, the appearance of nationalist-based religious groups such as NU strengthens the nation’s integrity by building awareness of binding religion and nationalism. (shrink)
