Truna 1* 1 UIN Sunan Gunung Djati Bandung, Indonesia; dodystruna@uinsgd.ac.id * Correspondence: dodystruna@uinsgd.ac.id Received: 2021-08-19; Accepted: 2021-09-15; Published: 19-09-2021 Abstract: This study discusses how religious development in Indonesia has resulted in switching the function of purity to non-purity in religious practices. Using a phenomenological approach, this review finds that some Muslims maintain their purity for various reasons, but some mix their beliefs with the local culture. This situation leads to the following study on a macro scale about Islam's indigenization in Indonesia's cultural landscape. This study found a relatively high cultural acculturation between Islam as a global religion and local Indonesian culture. The community reinforces this acculturation by promoting traditional leaders and the need for a sense of security that has been embedded in local communities. Keywords: Acculturation; cultural tradition; Indonesian anthropology; Islamic culture; social phenomenology. Abstrak: Kajian ini membahas bagaimana perkembangan agama di Indonesia mengakibatkan beralihnya fungsi puritanisme dalam praktik keagamaan. Dengan menggunakan pendekatan fenomenologis, tinjauan ini menemukan bahwa sebagian umat Islam masih mempertahankan kemurniannya dengan berbagai alasan, namun sebagian lagi mencampuradukkan keyakinannya dengan budaya lokal. Situasi ini mengarah pada studi berikut dalam skala makro tentang pribumisasi Islam dalam lanskap budaya Indonesia. Kajian ini menemukan adanya akulturasi budaya yang relatif tinggi antara Islam sebagai agama global dengan budaya lokal Indonesia. Masyarakat memperkuat akulturasi ini dengan memprioritaskan tokoh adat dan perlunya rasa aman yang telah tertanam dalam masyarakat setempat. Kata Kunci: Akulturasi; Antropologi Indonesia; budaya Islam; fenomenologi social; tradisi budaya. 1. Introduction The diversity of religious practices is a common phenomenon in almost all religions. The same phenomenon is also in Africa, North America, Latin America, Western Europe, Eastern Europe, and Northern Europe. Their respective regional culture influences their characteristics. Theologians are increasingly interested in how the major Christian and Islamic traditions integrate within African religion and contend with emergent religious groups that challenge their orthodoxy (Pye, 2017). In connection with the theme of this review, the above issue can contain two kinds of understanding. The first is a sociological perspective to understand the influence of religion on local culture. The second is phenomenological, which focuses on religious experiences as perceived by believers, called the life- world (Schutz, 2012). Here we should see the meaning behind these symptoms for the followers, not the sense from others' point of view. Religion has a transformative function, transforming from a condition to the new state it wants (Henriksen, 2017). Religion contains a unique and absolute truth, as its adherents believe (Barro & McCleary, 2019). It demands its followers to follow the truth. Faith requires and emphasizes that everything that is not in line with the concept of religious truth must be changed and 'put right' (Jenkins, Berry, & Kreider, 2018). Likewise, a religious adherent is bound by all the obligations that must be obeyed without demanding (Kemp, 2019). As a devout believer, one is required to uphold religious values (Hong & Handal, 2020).
