A free church in the sense used by members of the COC is similar yet different then most churches by the fact that it maintains a complete separation of church and state.
The COC is an example of a multi-denominational free church with primary focus of being a Neo-Zoroastrian religious organization established to bring together persons whom share a similar belief and mode of worship. The COC is composed of conjoined Family Oriented Monastic Orders each is an Individual Orthodox Member Monastery of the Church of Cognizance intrinsically separated from any government (as opposed to a theocracy, an "established", or state church). A free church does not define government policy, nor have governments define church policy or theology, nor seeks or receives government endorsement or funding for its general mission..
