The separation between church and state is significant as it preserves religious freedom and prevents the government from favoring or discriminating against religions. This principle ensures that laws and policies are shaped by democratic principles rather than religious doctrines, promoting pluralism in society. It also protects religious institutions from government interference, allowing them to function independently. By maintaining this separation, a more equitable public policy environment is established, enabling citizens of various beliefs to coexist harmoniously without fear of persecution or preference based on religion.
