grep -f namefile textfile

There are quite a lot of other ways you could process the two files, but it depends on exactly what output you need and what you're going to do with it.

Usage: grep -hblcnsviw pattern file . . .

If both files are in the same format, you can do:

EDIT: You'll probably need to sort the files first:
join -v 1 <(sort namefile) <(sort textfile)
