Most non-profits (tax exempt) do no charity work, or so little it doesn't amount to anything. That said, the tax code separates religious organizations into a separate category from charities and non-profits.
As a matter of fact, if you look at Tax code: TITLE 26 > Subtitle A > CHAPTER 1 > Subchapter F > PART I > § 501, there are almost 30 different categories of tax exempt organizations. Things like Boy/girl Scouts, cemeteries, fraternities and the Rotary club are exempt, but I don't see them doing much charity work.

I forgot to add the local gun club with over 3,000 members. No charity there.
