This has been on my mind because of a church in London where they put pressure on members to tithe 10%. I've never thought it necessary to give this amount unless perhaps one is not paying tax, rent and bills.
I thought I'd give a link by John MacArthur which shows how Israelites were actually required to pay over 20%, and that what they gave was used in a similar way to how the money we pay in tax is used.

But according to J.B.Jordan, who teaches that 10% is correct, the government should never charge over 10% in tax so that the biblically correct amount can go to the church.
This is an unlikely situation, however. So for a democracy where taxes are over 20%, and where the individual is able to have a say in how his taxes are used, the money we give to the church should really be the voluntary amount, where a person gives what his heart moves him to give. Eg Exodus 25:2.
Is this correct, or should someone who's paying over 20% in taxes still tithe 10%?
