The free market is under civil law. Civil law in principle precedes the free market and establishes its conditions by shaping public behavior and attitudes. It is enforced by rulers who are ministers of God. Taxation as such is not theft, contrary to some libertarian theorists. Lawful authorities are entitled to economic support.
Taxation supports the State.
Paul calls on Christians to obey lawful authorities. This may mean challenging one authority in the name of another. Authorities are to some extent in competition with each other. It is not unlawful to pit one against the other, as Paul's tactics in Acts indicate. Freedom is sometimes achieved by using one authority to reduce the power of another.
