I'm going to assume the setup was the same with Mathematica 7 as for 
Mathematica 8: the kernel executable is hidden inside the Mac package 
/Applications/Mathematica.app.

If you right-click (or Ctrl-click) on that item in Finder, select Show 
Package Contents. In the new Finder window that opens, look at

   Contents/MacOS/MathKernel

That's the executable you actually want. So, for example, if you type in 
a Terminal command line:

   /Applications/Mathematica.app/Contents/MacOS/MathKernel

then you'll get an interactive command-line session. And if you have a 
file batch.m of legitimate Mathematica expressions, then the following 
_will_ work:

   /Applications/Mathematica.app/Contents/MacOS/MathKernel <batch.m 
 >batch.out

(assuming your current directory is the location of batch.m, of course).

Now just either add 
/Applications/Mathematica.app/Contents/MacOS/MathKernel to your PATH or 
make an alias for it in the directory where you're working (or some such 
thing).
