I read that report earlier, but I did wonder whether donations to churches qualified as charitable donations, for the purposes of these numbers (ie the 62% 46% split).
This reference to IRS practice certainly indicates that the IRS sees tithing as tax deductible in the same way as charitable donations:

Need some more detail on the research.

Could there be any greater conceit, than for someone to believe that the universe has to be simple enough for them to be able to understand it ?
