Why should churches or anyone pay taxes? Tax is a "religious " mandate according to biblical text. 10% income was set by biblical text called a tithe.
Taxation is a form of capitalism slavery. It has nothing to do with true freedom where that everyone, every business or every money using institution (schools, colleges, museums, hospitals, you name it, etc. ) has a bank account of virtually a million billion trillion unlimited dollars to insure that money or the lack there of is not any issue nor a means of enslaving people to minimum wage slave labor wages.
Most religion seems to take the same attitude to paying taxes as do the wizards and witches in the Discworld novels of Sir Terry Pratchett.
That being that magical folk would be quite willing to pay tax, IF anyone asked them to.
However it was made abundantly clear that asking magical magical folk to pay their tax was a VERY unwise idea indeed. As might be attested to by several former tax collectors now living happily on lilly pads in frog ponds.
God is a frog, from crawling on land to lost in space.
Stealing souls is rewarded by corrupted Governments . In fact, they don't allow non religious to lead a nation.
If Jesus honestly cared for the poor, he would non tax artist who are the poorest paid field. Artist have many time longer history than religion and greater influence. Artist cross all cultures and medicines.
Albert Einstein. "I'm enough of an artist to draw freely on my imagination. Imagination is more important than knowledge. Knowledge is limited; imagination encircles the world."
