The kernel is not hidden, it should be in (Directory Mathematica is
installed in)/Mathematica\  You can
start it from the command line in a terminal by providing that path.  If
you start the kernel from the command line and redirect input, the
kernel will run in batch mode, using the input file to get the initial
expressions and leaving the results in standard out (or you can redirect
the output as well), eg. (path)/MathKernel < infile > outfile.

By the way, in OS X ctrl-Mouse click on the icon of a .app file will
give you a menu in the Finder.  The option Show package contents will
allow you to see the files that are contained in the .app.  This is the
way Mathematica is delivered on OS X, so if you ctrl-click on the
Mathematica icon in the Finder you can probe the directory structure to
see where things are stored.
