Which principle is directly associated with the concept of the separation of church and state?

The principle of religious equality closely aligns with the concept of the separation of church and state. This principle ensures that individuals have the right to practice their religion freely without interference from the government and that the government does not favor one religion over another. This separation is fundamental to maintaining a pluralistic society where various beliefs coexist without state endorsement or discrimination.

By emphasizing religious equality, the state upholds the idea that all citizens, regardless of their religion or lack thereof, deserve equal treatment. This is crucial in preventing the government from establishing or promoting a particular religion, which would violate the rights of those who may adhere to different faiths or none at all.
