Answer:
Separation of church and state
Explanation:
The term separation of church and state does not mean that separate religion from people's lives or separate it from political but it is about the public that they can bring their religion-related issues in front of all public. But it should not be there that political favor one religion or ignore other religions but even do favor all religions in the same way. The term or phrase separation wall was first used by Roger Williams in 1635. But the term separation of church and state is not mentioned in the first constitution law. This law is only applicable to the federal government not to involve in any religious matter. Even it has been protection provided in the constitution law for their liberty for religion.
