This study investigates Indonesian students’ viewpoints on interfaith marriages in East Nusa Tenggara. A total of 819 students from 52 universities and colleges participated in the poll, and their answers were improved through focus groups and interviews with various student and non-student groups. The findings show that the students are quite open to interfaith relationships and exhibit reasonable reasoning. Interfaith dating is common in academic environments, which encourage acceptance of interfaith unions. In an effort to foster tolerance, students are advocating for legislative changes that would facilitate interfaith marriages. However, there are several challenges on the path to interfaith marriages. The rigid restrictions of family, culture, and religion that dictate marriage decisions regularly clash with the idealism of students. Decisions about marriage are not just driven by personal preferences, but they are heavily influenced by religious, cultural, familial, and customary norms. Religious differences are still thought to be potential triggers for family conflicts, effects on social status, inheritance issues, and challenges in passing along knowledge to future generations. As a result, many students believe that religious conversion is a better option than interfaith marriage. Students’ views on interfaith dating and marriage may seem idealistic in light of the current social, cultural, religious, and political circumstances.
