A "Free Church" is an independent church that is intrinsically separate from government (as opposed to a created entity by the IRS through a 501c3). A free church does not accept church theology or policy definitions from the government (as 501c3 exempt status imposes upon all its churches). A free church also does not seek or receive government endorsements or funding to carry out its work.
All churches should either "organize" or "re-organize" by executing a Declaration of Trust.
The Declaraiton is rooted in English Common Law, which is the Biblical Law foundation for the American Federal and State Constitutions, which have protected more of our God given liberties than any other system of government in the history of mankind.
