Tax all Churches since Churches are businesses.

Organized religion has turned into big business, and thousands of churches across the country have sprung up due to the tax exempt status they enjoy.
A section from Wikipedia under Megachurch reads, "Another concern with megachurches is their tax-exempt status. These churches generate millions of dollars and are not subject to the same disclosures that charities are on tax-exempt revenues. This has received attention from the US Senate.[21] Megachurches have also been investigated for illegal contributions to the political campaigns of Republican candidates[22][23] and one has been accused of embezzlement.[24]."
If Churches are going to "Sell God", they should be taxed like any other business that has a product to sell.
