The phrase "separation of church and state" is designed to protect the integrity of both religion and government. This principle ensures that governmental institutions remain neutral towards religious beliefs, preventing the influence of any single faith in public policy. It safeguards individuals’ rights to practice their religion freely without state interference, and conversely, keeps religion from exerting control over state affairs. This separation promotes pluralism and peace within diverse societies, allowing various beliefs to coexist. It aims to uphold the principles of freedom and tolerance in a democratic framework.
