The Constitution and Bill of Rights are referring to a 'separation of the POWERS of CHURCH and STATE. Not separation of CHURCH and STATE.
Nowhere did the founding fathers state they wanted the CHURCH and STATE completely separate,as the Christian principles guided the forming of the constitution and bill of rights.
It's ON THE MONEY. In GOD WE TRUST.
Please quote the passages of Scripture that support a representative form of a Republic, and I will quote the passages form John Locke (a deist, not a Christian) which are almost word-for-word the description of our Constitution.
