A church tax? (part 2 of 6)

The Bible says "God loves a cheerful giver." This has been used to say that we should pay a church tax if it is introduced. The quote is from 2 Corinthians 9:7 which says:

"Each man should give what he has decided in his heart to give, not reluctantly or under compulsion, for God loves a cheerful giver."

The verse says we should not force people to give (compulsion). They should decide what they want to give. This way people will be giving willingly and cheerfully.

If there is a tax that is a set amount per person, will each person be giving "what he has decided in his heart to give" and not "under compulsion"?

I am asking these questions because I am concerned that we are turning away from the Word of God instead of towards it as we try to solve our problems.
