The rapid development of digital technology has significantly transformed patterns of social interaction and public communication. While digitalization has expanded access to information and public participation, it has also given rise to various ethical challenges, including the spread of hoaxes, hate speech, cyberbullying, and social polarization. This study aims to analyze the reactualization of the value of Belief in the One and Only God as a foundation for strengthening public ethics in the digital era. The research employs a qualitative approach through library research by examining relevant academic literature, books, and policy documents. The findings indicate that the value of Belief in the One and Only God embodies universal moral principles such as honesty, responsibility, tolerance, empathy, and respect for others, which remain highly relevant in addressing ethical issues in digital spaces. The reactualization of these values can be achieved through character education, value-based digital literacy, the cultivation of ethical digital culture, and the active involvement of families, educational institutions, and government agencies. Furthermore, strengthening public ethics should not rely solely on legal regulations but also on the internalization of spiritual and moral values in everyday life. Therefore, the integration of divine values into digital practices is essential for creating a civilized, inclusive, ethical, and sustainable digital public sphere.
