Faith does not factor in atheism. It simply means lack of theism. No belief.
And having 'no belief' is to have faith that there isn't something worth believing in...
@ Tyler
That would seem to required a degree of "faith" in that theory. An agnostic, on the other hand, is a "fence sitter" who doesn't really take a position either way.
That is my understanding as well...
@ allport
It is a way to live free from shame and expectations
So its fair to say that you have 'faith' that such a way of life will free you from such things...
